How to set valueForKey in UIActionSheet for buttons?

I am totally revamp one of the old project ,and in that they using UIActionSheet ,i am not familiar with it so please help me to find out .

UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:@"beard Selection" delegate:self cancelButtonTitle:@"Cancel"   destructiveButtonTitle:@""   otherButtonTitles:@"", @"", @"", @"", @"", @"", @"", @"", nil];

    NSLog(@"kishore calculation ");
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:0] setImage:[UIImage imageNamed:@"ca1.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:1] setImage:[UIImage imageNamed:@"ca2.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:2] setImage:[UIImage imageNamed:@"ca3.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:3] setImage:[UIImage imageNamed:@"ca4.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:4] setImage:[UIImage imageNamed:@"ca5.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:5] setImage:[UIImage imageNamed:@"ca6.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:6] setImage:[UIImage imageNamed:@"ca7.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:7] setImage:[UIImage imageNamed:@"ca8.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:8] setImage:[UIImage imageNamed:@"ca9.png"] forState:UIControlStateNormal];
    [[[popupQuery valueForKey:@"_buttons"] objectAtIndex:9] setImage:[UIImage imageNamed:@"ca10.png"] forState:UIControlStateNormal];

    popupQuery.actionSheetStyle = UIActionSheetStyleBlackOpaque;
    [popupQuery setTag:Cap];
    [popupQuery showInView:self.view];

UIActionSheet is like a UIAlertView ,in that they tried to add buttons but i am getting error like this ,

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ valueForUndefinedKey:]: this class is not key value coding-compliant for the key buttons.'

guide me to over come this :)

Solution

  • This code is using KVO to try to access private properties of the UIActionSheet class. This is a bad idea, and may get your app rejected from the app store.

    It's a bad idea because it relies on private implementation details of Apple's frameworks. In this case, it probably stopped working because Apple changed those private implementation details.
