Answer 1

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 shorter Version in swift 5

extension UIView {
   var xsuperView = self.superview

   while xsuperView != nil {
        if let superView = xsuperView.self as? T {
            return superView
        } else {
            xsuperView = xsuperView?.superview
        }
    }
}

Answer 3

The best way to do this is:

CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
UITableViewCell *cell = (UITableViewCell*)[self.tableView cellForRowAtIndexPath:indexPath];

Answer 4

if ([[button superView] isKindOfClass:[UITableViewCell class]]) {

}

else //check next :

Answer 5

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
