EXC_BAD_ACCESS on UIAlertview code=1

问题

I am getting the EXC_BAD_ACCESS on [alert show] line.

Why I am getting this?

 alert = [[UIAlertView alloc]initWithTitle:@"Application Alert" message:@"all date popup" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Update",nil];

 [alert show]; //EXC_BAD_ACCESS on this line

回答1:

Just make delegate nil ,don't apply self to delegate .code it like below

alert = [[UIAlertView alloc]initWithTitle:@"Application Alert" message:@"all date popup" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Update",nil];

[alert show];

if you are using self in delegate then you will have to use alert delegate method

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

then it will not give EXC_Bad_Excess.let me know if it works..!!!!happy coding....

This crash must be on iOS 6. Solution for this crash is as follow :

[alert performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
