Objective-C: imports

2009-07-10T15:39:00.001-07:00

There are two different ways of doing imports: with quotation marks and with angle brackets. For example,



#import  
#import "Tire.h"

The version with angle brackets is used for importing system header files. The quotes version indicates a header file that's local to the project. If you see a header file name in angle brackets, it's read-only for your project, because it's owned by the system. When a header file name is in quotes, you know that you (or someone else on the project) can make changes to it.

Objective-C - @class

2009-07-10T15:24:00.001-07:00

Objective-C introduces the @class keyword as a way to tell the compiler "this thing is a class, and therefore I'm only going to refer to it via a pointer." This calms the compiler down: it doesn't need to know more about the class, just that it's something referred to by a pointer.



#import 
@class Tire;
@class Engine;

@interface Car: NSobject
  :
  :
@end // Car

@class sets up a forward reference. This is a way to tell the compiler "Trust me, you'll learn eventually what this is, but for now, this is all you need to know."

@class is also useful if you have a circular dependency. That is, Class A uses Class B, and Class B uses Class A. If you try having each class #import the other, you’ll end up with compilation errors. But if you use @class B in A.h and @class A in B.h, the two classes can refer to each other happily.

Objective-c: color

2009-06-26T15:48:00.001-07:00

Colors can be created as white levels, using hue, or as an RGB composite.



UIColor *myWhiteTransparentColor = [ UIColor colorWithWhite: 1.0 alpha: 0.50 ];

UIColor *myColorHue = [ UIColor colorWithHue: 120.0 / 360.0
    saturation: 0.75
    brightness: 0.50
    alpha: 1.0
];

To create a simple RGB color, specify a set of four floating-point values for red, green, blue, and alpha (opacity) with values between 0.0 and 1.0. These represent values ranging from 0% (0.0) to 100% (1.0):



UIColor *myColorRGB = [ UIColor colorWithRed: 0.75
    green: 1.0
    blue: 0.75
    alpha: 1.0
];

The UIColor class also supports many static methods to create system colors, which are calibrated by the iPhone as closely as possible. These methods include the following, from UIColor.h:



+ (UIColor *)blackColor;      // 0.0 white
+ (UIColor *)darkGrayColor;   // 0.333 white
+ (UIColor *)lightGrayColor;  // 0.667 white
+ (UIColor *)whiteColor;      // 1.0 white
+ (UIColor *)grayColor;       // 0.5 white
+ (UIColor *)redColor;        // 1.0, 0.0, 0.0 RGB
+ (UIColor *)greenColor;      // 0.0, 1.0, 0.0 RGB
+ (UIColor *)blueColor;       // 0.0, 0.0, 1.0 RGB
+ (UIColor *)cyanColor;       // 0.0, 1.0, 1.0 RGB
+ (UIColor *)yellowColor;     // 1.0, 1.0, 0.0 RGB
+ (UIColor *)magentaColor;    // 1.0, 0.0, 1.0 RGB
+ (UIColor *)orangeColor;     // 1.0, 0.5, 0.0 RGB
+ (UIColor *)purpleColor;     // 0.5, 0.0, 0.5 RGB
+ (UIColor *)brownColor;      // 0.6, 0.4, 0.2 RGB
+ (UIColor *)clearColor;      // 0.0 white, 0.0 alpha

If you plan on reusing many different UIColor objects, you may also create instances of them:



UIColor *myWhiteTransparentColor = [ [ UIColor alloc ]
    initWithWhite: 1.0 alpha: 0.50
];

UIColor *myColorHue = [ [ UIColor alloc ]
    initWithHue: 120.0 / 360.0
    saturation: 0.75
    brightness: 0.50
    alpha: 1.0
];

UIColor *myColorRGB = [ [ UIColor alloc ] initWithRed: 0.75
    green: 1.0
    blue: 0.75
    alpha: 1.0
];

Objective-C: Font and size

2009-06-26T15:06:00.001-07:00

The text font (typeface) and point size can be set by assigning a UIFont object to the text view's font property. To create a UIFont object, use a static method named fontWithName:



UIFont *myFont = [ UIFont fontWithName: @"Arial" size: 18.0 ];
textView.font = myFont;

In addition, three other static methods exist for easily creating system fonts:



UIFont *mySystemFont = [ UIFont systemFontOfSize: 12.0 ];
UIFont *myBoldSystemFont = [ UIFont boldSystemFontOfSize: 12.0 ];
UIFont *myItalicSystemFont = [ UIFont italicSystemFontOfSize: 12.0 ];

Objective-C: Parse the date into integers

2009-06-24T14:40:00.002-07:00

Use the default styles defined in NSDateFormatterStyle.



NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterNoStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
NSString* currentTime = [dateFormatter stringFromDate:[NSDate date]];
[dateFormatter release];

Set your own time format:



NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setDateFormat:@"yyyy"];
int year = [[dateFormatter stringFromDate:[NSDate date]] intValue];

[dateFormatter setDateFormat:@"MM"];
int month = [[dateFormatter stringFromDate:[NSDate date]] intValue];

[dateFormatter setDateFormat:@"hh:mm:ss"]
NSString *time = [dateFormatter stringFromDate:[NSDate date]];

[dateFormatter release];

What's the NSDateFormatter format specifiers are available to format the string?

However, you could Use the NSDateComponents class instead



NSCalendar *calendar= [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSCalendarUnit unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  
    NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | 
    NSSecondCalendarUnit;
NSDate *date = [NSDate date];
NSDateComponents *dateComponents = [calendar components:unitFlags fromDate:date];

NSInteger year = [dateComponents year];
NSInteger month = [dateComponents month];
NSInteger day = [dateComponents day];
NSInteger hour = [dateComponents hour];
NSInteger minute = [dateComponents minute];
NSInteger second = [dateComponents second];

objective-c: iPhone screen

2009-06-08T10:57:00.000-07:00

To build a window, you need a frame. A frame is a rectangular region on the screen where your content should be displayed. Two methods exist inside a class named UIScreen to determine this.

The bounds method returns the entire screen's boundaries, including the space used by the status bar:


CGRect screenBounds = [ [ UIScreen mainScreen ] bounds ];

The applicationFrame method returns the displayable portion of the screen in which your application will be displayed. This space does not include the status bar:


CGRect screenBounds = [ [ UIScreen mainScreen ] applicationFrame ];

Objective-c: Class Introspection

2009-05-28T10:45:00.000-07:00

You can ask an object about its class:


NSLog(@"The class is %@", [myObject className]);

Testing for general class membership (subclasses included):


For example, in this code, isKindOfClass: would return YES because, in Foundation, the NSArchiver class inherits from NSCoder: 

NSMutableData *myData = [NSMutableData dataWithCapacity:30];
id anArchiver = [[NSArchiver alloc] initForWritingWithMutableData:myData];
if ( [anArchiver isKindOfClass:[NSCoder class]] )
  ....

Testing for specific class membership (subclasses excluded):

 
For example, in this code, isMemberOfClass: would return NO: 

NSMutableData *myData = [NSMutableData dataWithCapacity:30];
id anArchiver = [[NSArchiver alloc] initForWritingWithMutableData:myData];
if ([anArchiver isMemberOfClass:[NSCoder class]])
    ...

#define UIColorFromRGB(rgbValue) [UIColor \
    colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
    green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
    blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

iphone SDK: Stretchable Images

2009-05-21T09:31:00.001-07:00

Stretchable Images are an interesting concept. A stretchable image is a resizable image that knows how to resize itself intelligently so that it maintains the correct appearance. End caps are the parts of an image, measured in pixels, that should not be resized. We want the bevel around the edges to stay the same no matter what size we make the button, so we specify a left end cap size of 12. For example.


UIImage *buttonImageNormal = [UIImage   imageNamed:@"whiteButton.png"];
UIImage *stretchableButtonImageNormal =   [buttonImageNormal
         stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[myButton   setBackgroundImage:stretchableButtonImageNormal   forState:UIControlStateNormal];

Objective-C: Check whether an NSArray contains a certain object or not?

2009-05-20T14:06:00.001-07:00

For checking whether an NSArray contains a certain object or not, you should use the -containsObject: method, as in the following example:

 
NSArray *array;

array = [NSArray arrayWithObjects: @"Nicola", @"Margherita",
                                   @"Luciano", @"Silvia", nil];

if ([array containsObject: @"Nicola"]) // YES
  {
    // Do something
  }

-containsObject: compares the objects using -isEqual:, which is usually what you want: e.g., two NSString objects containing the same UNICODE characters would be considered equal, even if they are not the same object.
To get the index of an object, you can use -indexOfObject:, which returns the index of the object (better, of an object equal to the argument), or the constant NSNotFound if no object equal to the argument can be found in the array, as in the following example:


NSArray *array;
int i, j;

array = [NSArray arrayWithObjects: @"Nicola", @"Margherita",
                                   @"Luciano", @"Silvia", nil];

i = [array indexOfObject: @"Margherita"]) // 1
j = [array indexOfObject: @"Luca"]) // NSNotFound

iPhone SDK: Getting Paths to Directories of an iPhone application

2009-05-20T10:33:00.001-07:00

Here is some notes about how to get the path to the common directories of iPhone application:


// To obtain the Bundle 
NSString *path = [[NSBundle mainBundle] pathForResource:@"mydocument" ofType:@"plist"];
list = [[NSArray alloc] initWithContentsOfFile:path];

// To obtain the <Application_Home>/tmp/ path in NSString
NSString *tempPath = NSTemporaryDirectory();
NSString *tempFile = [tempPath stringByAppendingPathComponent:@"tempFile.txt"];

// To obtain the <Application_Home>/Library/Caches path in NSString
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDirectory = [paths objectAtIndex:0];
NSString *cacheFile = [cachesDirectory stringByAppendingPathComponent:@"cache.txt"];

// To obtain the <Application_Home>/Documents/ path in NSString
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentFile = [documentsDirectory stringByAppendingPathComponent:@"document.doc"];

Objective-C: Quick Way to Deal with Dates

2009-05-20T09:26:00.001-07:00

NSDate is the name of the class that is used to work with dates and NSDateFormatter is used to transform dates into something that can be presented to the user.

The most common thing people want to do with dates is to simply get today's date. Here is how you do that:


NSDate *date =[NSDate date];

Now, if you were to write this out to the log or use as text on a user control then you would end up with something like this: 2009-05-20 08:36:33 -0500

But How Do You Get the Date When It Is Not Today's Date?

All you need to do is this:


NSDate *date = [NSDate dateWithNaturalLanguageString:@"05/10/09"];

To pretty this up, use NSDateFormatter like so:


NSDateFormatter *df = [[NSDateFormatter alloc] init];
df.dateStyle = NSDateFormatterLongStyle;
[ASFunctions logThis:@"formatted date:" andThisObject:[df stringFromDate:date]];
[df release];

This code will output something like this to the log:

iPhone SDK: How to share variables between views?

2009-05-20T09:20:00.001-07:00

Approach 1

Either

create instance vars in both controllers and set them accordingly to point to the same object (from the App Delegate)
create an instance variable on the App Delegate and access it from within the view controllers

Approach 2

Simply declare the variable in some shared header file, then import that file wherever you want to access that variable.



NavigationBaseAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
UINavigationController *navigationController = [delegate navigationController];
 
AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil];
[navigationController pushViewController:anotherViewController animated:YES];
[anotherViewController release];

Seven things all iPhone apps need

2009-05-20T08:44:00.001-07:00

If you've got an iPhone or iPod Touch you've probably downloaded some apps to play with. If you've downloaded more than one, you'll quickly realize that some are better than others.

For developers there are lots of choices to make when crafting an app; not only does the app need to be based around a good idea, but the app needs to behave in a way that is familiar to iPhone users. If it takes a user more than a minute or so to figure out how your app works, chances are they'll never use it again and will leave you a bad rating.

Both outcomes are bad, particularly when you consider that to be successful in the store, your app needs to be in one of the 'top' something lists.

An iPhone app should do one thing well
Make sure it performs all tasks well
Use icons and imagery that are familiar
All apps should autosave
Let me listen to my music
Where appropriate, all apps should be location aware
Focus on minimal startup time

Setting Up Your Shell Environment on Leopard

2008-12-01T12:02:00.001-08:00

You can make your own personal configurations to ~/.bashrc and ~/.bash_profile. As a general rule, things that affect your environment should go in the .bash_profile file and things that affect the shell specifically should go in the .bashrc file.

The syntax to add a directory to the $PATH is as follows:

$PATH=/new/directory:/another/new/directory:"${PATH}"
