appDelegate synthesizing

[ovidiu]

Hello everyone.

I was just wondering how you people deal with the appDelegate.

So for me, the way I do it is the next one:

@interface MyClass : NSObject {

	MyAppDelegateClass *appDelegate;	
}
@property (nonatomic, assign) MyAppDelegateClass *appDelegate;	

@implementation MyClass

@synthesize appDelegate;

-(id) init{
[self setAppDelegate:(MyAppDelegateClass *)[[UIApplication sharedApplication] delegate]];
return self;
}

@end

Nothing is wrong so far, but I just wanted to know if that is a good habit to use or not. How do you do it?

You don't need to store another reference to the App Delegate. Any time you need it, just call:

MyAppDelegate* delegate = (MyAppDelegate*)[[UIApplication sharedApplication] delegate];

And replace MyAppDelegate with whatever the class name for your App Delegate is.

Yes, but I want to use the appdelegate in a lot of methods inside the applications, I don't like to write that whole line. I just wanted to use a shorter version, which is appDelegate.

How about just creating a #define like this:

#define  APPDELEGATE   ((MyAppDelegate*)[[UIApplication sharedApplication] delegate])

Now anywhere you want to access the App Delegate, just use "APPDELEGATE" in code.

Very nice elegant solution, I didn't think of that. Thanks.
