Why do both init functions get called

Question

If I have a class that is setup like this to customize a UIView.

@interface myView : UIView

- (id)init {
    self = [super init];
    if(self){
             


        

Answer 1

UIView init calls UIView initWithFrame:. Since you override both, calling your init method results in your initWithFrame: method being called:

In other words: your init calls UIView init. UIView init calls initWithFrame:. Since you override initWithFrame:, your initWithFrame: is called which in turn calls UIView initWithFrame:.

The solution, since your initWithFrame: will always be called, is to remove the call to foo from your init method.
