I have found a solution for this problem. I know it is not the way but Sure that it works till iOS 8 will be launched in the market.
Reason for Crash:
in iOS 7 [self.subViews objectAtIndex: i]
returns UIView
Instead of UIImageView
and setImage
is not the property of UIView
and the app crashes. I solve my problem using this following code.
Check Whether the subview is UIView
(for iOS7) or UIImageView
(for iOS6 or earlier). And If it is UIView
I am going to add UIImageView
as subview on that view and voila its working and not crash..!!
-(void) updateDots
{
for (int i = 0; i < [self.subviews count]; i++)
{
UIImageView * dot = [self imageViewForSubview: [self.subviews objectAtIndex: i]];
if (i == self.currentPage) dot.image = activeImage;
else dot.image = inactiveImage;
}
}
- (UIImageView *) imageViewForSubview: (UIView *) view
{
UIImageView * dot = nil;
if ([view isKindOfClass: [UIView class]])
{
for (UIView* subview in view.subviews)
{
if ([subview isKindOfClass:[UIImageView class]])
{
dot = (UIImageView *)subview;
break;
}
}
if (dot == nil)
{
dot = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, view.frame.size.width, view.frame.size.height)];
[view addSubview:dot];
}
}
else
{
dot = (UIImageView *) view;
}
return dot;
}
Hope this solve ur issue too for iOS7. and If Anypone find the optimal solution for that please comment. :)
Happy coding
