[Solved] application life cycle issue
I solved this problem, just overrides the UINavigationBar & in LayoutSubViews set the height of navigationBar. @implementation UINavigationBar (customNAvigBar) – (void)layoutSubviews { [self setFrame:CGRectMake(0, 0, 320, 55)]; } @end that means whenever i draws the navigationBar it calls automatically & sets the height. solved application life cycle issue
