How to find my specific button over window? - ipad

Question

I have created by custom UIButton for iPad application.
Now for specific reasons, I want to hide those buttons. To do that I am using following code:
NSMutableArray *viewArray = [[NSMutableArray alloc] init];
// Get all the windows
for (UIWindow *window in [[UIApplication sharedApplication] windows])
{
// check for main screen
if (![window respondsToSelector:#selector(screen)] ||
[window screen] == [UIScreen mainScreen])
{
// check for all the subviews available in window
for (UIView * view in [window subviews]) {
// check whether it supports this method
if ([view respondsToSelector:#selector(isKindOfClass:)]) {
// type cast to button
// UIButton *btn = (UIButton *)view;
// if its type of my custom button class
if ([[view class] isKindOfClass:[DINNextLTProBoldButton class]]) {
// hide view and add to array
[view setHidden:YES];
[viewArray addObject:view];
}
}
}
}
}
But I am not able to get my custom buttons in this array. It stays empty only even thought the view which is being appeared on window/screen have those buttons.
Where I am going wrong? Please guide me.

Answer 1

try this (untested, but it gives the basic idea)
- (void)hideViewOfClass:(Class)clazz inHeirarchyOfView:(UIView *)view
{
for (UIView *subview in [view subviews])
{
if ([subview isKindOfClass:clazz])
subview.hidden = YES;
else
[self hideViewOfClass:clazz inHeirarchyOfView:subview];
}
}
call this function at first like:
for (UIWindow *window in [[UIApplication sharedApplication] windows])
[self hideViewOfClass:[DINNextLTProBoldButton class] inHeirarchyOfView:window];
