I'm getting the UITableViewCell a UIButton belongs to like this:
-(void)buttonHandler:(UIButton *)button {
OrderCell *cell = [[button superview] superview];
NSLog(@"cell.item = %@", cell.item.text);
And it works fine in anything before iOS 7. But gives me:
[UITableViewCellScrollView item]: unrecognized selector sent to instance 0x17ae2cf0
if I run the app in iOS 7. BUT if I do:
-(void)buttonHandler:(UIButton *)button {
OrderCell *cell = [[[button superview] superview] superview];
NSLog(@"cell.item = %@", cell.item.text);
Then it works in iOS 7 but not earlier?!?!?!
I'm circumventing the issue by doing this:
OrderCell *cell;
if([[[UIDevice currentDevice] systemVersion] isEqualToString:@"7.0"])
cell = [[[button superview] superview] superview];
else
cell = [[button superview] superview];
NSLog(@"cell.item = %@", cell.item.text);
but WTF is going on!? Does anyone know why this happens?
Thanks!
To complete the answer of @thomas-keuleers this is the swift method:
extension UIView {
func findSuperViewWithClass<T>(superViewClass : T.Type) -> UIView? {
var xsuperView : UIView! = self.superview!
var foundSuperView : UIView!
while (xsuperView != nil && foundSuperView == nil) {
if xsuperView.self is T {
foundSuperView = xsuperView
} else {
xsuperView = xsuperView.superview
}
}
return foundSuperView
}
}
and you simply call like that:
child.findSuperViewWithClass(TableViewCell)
A better solution is to add a category for UIView(SuperView), and calling it by:
UITableViewCell *cell = [button findSuperViewWithClass:[UITableViewCell class]]
This way, your code works for all future and past iOS versions
@interface UIView (SuperView)
- (UIView *)findSuperViewWithClass:(Class)superViewClass;
@end
@implementation UIView (SuperView)
- (UIView *)findSuperViewWithClass:(Class)superViewClass {
UIView *superView = self.superview;
UIView *foundSuperView = nil;
while (nil != superView && nil == foundSuperView) {
if ([superView isKindOfClass:superViewClass]) {
foundSuperView = superView;
} else {
superView = superView.superview;
}
}
return foundSuperView;
}
@end
