Iphone: Alert View

Here we learn about the UIAlertView Of iphone Application: just how to show the Alert Messages in Iphone Application.

Alter View:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"MSG" delegate:nil/self cancelButtonTitle:@"OK" otherButtonTitles:@"cancel",nil]; 

alert.tag = 1;

[alert show];

[alert release];

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex

{

     if(alert.tag == 1)

     {

        if(buttonIndex == 0)

             // statements

else

  //statements

       

     }

}

Change UIAlertView Button Color:

Create the object of UIAlertView , the call automatically following method:

- (void)willPresentAlertView:(UIAlertView *)alertView 

{ 

[[[alertView subviews] objectAtIndex:1] setBackgroundColor:[UIColor redColor]];

    /*

      Here index 0 = Title , 1 = cancel Button , 2,3.... = otherButton

*/ 

} 

Alter View without Button:

UIAlertView *baseAlert = [[UIAlertView alloc] 

initWithTitle:@"" 

message:@"Message to user \n with asynchronous \ninformation" 

delegate:self cancelButtonTitle:nil 

otherButtonTitles: nil]; 

[NSTimer scheduledTimerWithTimeInterval:2.0f target:self selector: @selector(performDismiss:) userInfo:nil repeats:NO]; 

[baseAlert show]; 

baseAlert.frame = CGRectMake(0,190,320, 120);

- (void) performDismiss: (NSTimer *)timer 

{ 

[baseAlert dismissWithClickedButtonIndex:0 animated:NO]; 

}
