UIImageview设置图像崩溃

Question

I'm setting image to a UIImageView using in the below code

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    for(int i=0;i<[radioButtons count];i++){
        [[radioButtons objectAtIndex:i] setImage:[UIImage imageNamed:@"checkbox_unchecked.png"]];

    }    
    UIImageView *imageViews=(UIImageView *)[self.view viewWithTag:indexPath.row];
    [imageViews setImage:[UIImage imageNamed:@"checkbox_checked.png"]];
}

So on clicking any tableview cell the images gets sets. But once if I click on objectatindex:0 then the app crashes. I'm unable to fix this.

Below is the crash log:

Answer 1

I think you are not getting UIImageView Object,you are getting uiview types object that's why it crashes. you should try to Define another tag property like 999+indexPath.row. Got it somewhere you define the tag=0 or IB automatically takes tag=0 to all object so it taking uiview with tag 0 not uiimageView

Answer 2

this means that you are sending message -(void)setImage to UIView, not to UIImageView. Make sure that view with tag indexPath.row and all radioButtons in array are actually UIImageView
