iPhone/iOS: Will there be called any method if a UIView is added as a subview

If I add a view as a subview like so

[self.view addSubview:mySubview];

Will there be called any method on mySubview, that I could开发者_StackOverflow中文版 override to add some custom behavior?

Adding a view to a (new) superview triggers

- (void)willMoveToSuperview:(UIView *)newSuperview

and

- (void)didMoveToSuperview.

See the UIView Reference for more.

You can override these two:

- (void)willMoveToSuperview:(UIView *)newSuperview
- (void)didMoveToSuperview

Take a look in the documentation for UIView for similar methods.

- (void)willMoveToSuperview:(UIView *)newSuperview
- (void)didMoveToSuperview

From UIView Doucumentation

willMoveToSuperview:, didMoveToSuperview—Implement these methods as needed to track the movement of the current view in your view hierarchy.
