I just wanted to see alert view without doing any action on clicking ok or cancel buttons.Please help me out. please guide me.Thanks.
That's just the debugger (gdb) initialising.
If the debugger isn't started on app launch (which will be the case if you just build and run instead of build and debug) the debugger will start and initialise when the app encounters a problem.
The problem you have here is in your alert view init line. Everything is fine until the last parameter: otherButtonTitles:
- notice the plural on titles, not title. This means the parameter takes a nil-terminated list of items - this is also stated in the documentation.
you should amend your code so that parameter is nil-terminated like so:
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Current Location" message:@"Show Current Location?" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
