    [self.view addSubview:obj.view];
   //[self.view insertSubview:obj.view aboveSubview:self.view];
    [UIView commitAnimations];

Are you using a TableView ?

Some objects do (strange) things, so it may be related.

If possible give use more information about your self object.

By the way, you can try

[ self.view insertSubview: atIndex: ];

or

[ self.view insertSubview: aboveSubview: ];>

Good Luck !
