Warning message for click button in iphone sdk 4.3

Question

I am starting to program xcode. Please tell me how to display a warning message when we are about to press a button in xcode-iphone-4.3

My code is as follows:

- (IBAction)buttonPressed:(id)sender{ UIAlertView* mes=[[UIAlertView alloc] initWithTitle:@"Hello World!!!!!!" message:@"This is the Iphone app" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [mes show]; [mes release]; 

Please help me with this.

Answer 1

 -(IBAction)buttonOnePressed:(id)sender { UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Clicked button 1" message: @"Alert Message here" delegate: self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",nil]; [alert setTag:1]; [alert show]; } -(IBAction)buttonTwoPressed:(id)sender { UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Clicked button 2" message: @"Alert Message here" delegate: self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",nil]; [alert setTag:2]; [alert show]; } 

Below is the delegate method for tracking button clicks on Alertview.

  -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (alertView.tag == 1) { // UIAlertView with tag 1 detected if (buttonIndex == 0) { NSLog(@"user pressed Button Indexed 0"); // Any action can be performed here } else { NSLog(@"user pressed Button Indexed 1"); // Any action can be performed here } } else if (alertView.tag == 2) { // UIAlertView with tag 2 detected if (buttonIndex == 0) { NSLog(@"user pressed Button Indexed 0"); // Any action can be performed here } else { NSLog(@"user pressed Button Indexed 1"); // Any action can be performed here } } } 

You can set a tag on a UIAlertView if you have more than one UIAlertView , and you can determine which UIAlertView clicked in its clickedButtonAtIndex deletion method using the corresponding tag.

In IBAction you need to write the code and give Connections to the button

Answer 3

Create an IBAction for your button and add code to view alerts in this method.
