superview

What are the coordinates used in UIViews and their corresponding superviews? I have this code which i would like to detect a 'corridor' where the user can touch... similar to this image: alt text http://img17.imageshack.us/img17/4416/bildschirmfoto20100721u.png This is the code i have: CGPoint touch = [recognizer locationInView:[shuttle superview]]; CGPoint centre = shuttle.center; int outerRadius = shuttle.bounds.size.width/2; int innerRadius = (shuttle.bounds.size.width/2) - 30; if ((touch.x < outerRadius && touch.y <outerRadius)){ NSLog(@"in outer"); if(touch.x > innerRadius && touch.y >

I have a UISegmentedController i have 3 UIViewControllers Like photos,frames,gallery. I add those 3 Views in Superview Using 'addSubView'. In frames view i have added a subview that name as EditView. In EditView i have done some changes, i want to update these changes in frames view. But when am removing EditView from frames view any single method doesn't calling. Then how to update the changes from subview in superview. Tree: UISegmentedController -> Frames(Su) -> EditViews(Subview). Can any one help me.. Yuvaraj.M I found the code to update something in superview from subview. Please use

I have the line of code below... How would I modify it to insert the subview in the superview's view named 'foo'? [[self superview] addSubview:copy3]; There are more than 1 ways of doing this - 1.have an IBOutlet reference in your code. This is created from xcode Interface builder. Once you have this then it fairly straight forward - [iboutlet_foo_object addSubview:copy3]; 2. tag the view that you are interested in. Again tagging a view can be done from xcode Interface builder or from code. After that - Foo *fooObj = [[self superview] viewWithTag:tagInt]; [fooObj addSubview:copy3]; 3.Finally

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
