But my application is crash when I click on that button. Can you help that how I'll perform any event in subview.

Answer 1

remember this: 3 Nested views , No.1 contains NO.2 and NO.2 contains NO.3, you touch the screen, actually No.1 become the first responder, if NO.1's userInteractionEnabled == YES, then NO.2 could get the responder and so on, usually view's userInteractionEnabled is YES, but some are not , like UIImageView ...

Answer 2

you should add your second view like: you should add a uiview IBOutlet on which you show the second View; then make it proprty and add subview of secondView like below;

FirstView.h

@class secondView; { secondView *secondViewObj; }

@property(nonautomic,retain)secondView *secondViewObj;

in the implementation file Firstview.m @synthesize secondViewObj;

then in you viewDidLoad method you have uiview outlet mysecondsubView in the firstView on which you show the second view.

self.mysecondSubView=[[secondView alloc]initWithNibName@"secondView" nibBundle:nil];
