UIAlertView on launch!

[dsinc14]

Hello Everyone,

I am new to development on the iphone and ipod touch, and my first app is almost complete. The only thing I have to do is to make a UIAlertView on the first three lauches, but I am not sure how to do this! Here is the code I have so far, and it works great to make an alert on launch, but it pops up every time.

- (void)applicationDidFinishLaunching:(UIApplication *)application {  
	 {
		alert = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
		[alert show];
		[alert release];
	}
}

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {
	
	if (buttonIndex == 0) {
		
	}
    
    // Override point for customization after app launch    
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
}

Can anyone help me?

I would make an NSInterger to have a count of 0 by default. Each time the app launches, you would add 1 to the count and save the count with NSUserDefaults on each close. Then set up your alert view to only be triggered on the first three launches like so:

- (void)applicationDidFinishLaunching:(UIApplication *)application {  
	 {
if (count < 3){
		alert = [[UIAlertView alloc] initWithTitle:nil message:nil delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
		[alert show];
		[alert release];
	}
}
else {

}
}

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {
	
	if (buttonIndex == 0) {
		
	}
    
    // Override point for customization after app launch    
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
}

Sorry But I don't understand what to do here "I would make an NSInterger to have a count of 0 by default. Each time the app launches, you would add 1 to the count and save the count with NSUserDefaults on each close." Can you explain it a little easier?

Just add an alert view code, in the viewDidLoad of the viewcontroller.m

[rickrets]

put this in the .h:

BOOL alert;

@property (nonatomic, readonly) BOOL alert;

in the .m:

@synthesize alert;

if (alert == FALSE) {
//
//your alert view
//
alert = TRUE;
}
