I am having an application on iTunes store which displays some UILabel and UIWebView on UIAlertView. According to session video,
You can really change accessoryView to customContentView in iOS7 (and it seems that in iOS8 as well) UIAlertView
[alertView setValue:customContentView forKey:@"accessoryView"];
Try this code:
UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"TEST" message:@"subview" delegate:nil cancelButtonTitle:@"NO" otherButtonTitles:@"YES", nil];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
[av setValue:v forKey:@"accessoryView"];
v.backgroundColor = [UIColor yellowColor];
[av show];
Remember that you need set custom accessoryView before the call [alertView show]
