Question

I have a button place on a view partially… its one half is over the view and the other half is just sort of floating. So if A is my base view and B is placed over it and I have this button added over B. If i click on the button on the part which comes above B it receives the touch and performs the action, but if this touch is outside the area of B than the touch is not performed…. what am I doing wrong here… ? Any help is appreciated.

here is how I am adding the button.. I am trying to dynamically delete buttons similar to the way the apps are deleted in IOS.

UIButton *deletButton1 = [UIButton buttonWithType:UIButtonTypeCustom] ;
        deletButton1.frame = CGRectMake(25, -5, 30,30);;
        deletButton1.backgroundColor = [UIColor clearColor];
        deletButton1.tag=1;
        UIImage *buttonImageNormal1 = [UIImage imageNamed:@"delete.png"];
        [deletButton1 setBackgroundImage:buttonImageNormal1 forState:UIControlStateNormal];
        [deletButton1 addTarget:self action:@selector(deleteButton:) forControlEvents:UIControlEventTouchUpInside];

[self.addButton1 addSubview:deletButton1]; 

Here is a screen shot..

For the record, a subview doesn’t HAVE to be inside the parent view’s frame to receive touches if you override the proper methods of the parent view.
