iphone - Gap between Navigation bar and view controller content -

I am creating a "no connection" view in the difference between viewing the navigation bar and controller contents.

I want to subclass the UINavigationViewController and move the content down a bit of view controllers.

The question is how to do it correctly?

My current solution is working, but it is quite a hack. I want to make it better. Sub-class of AGNVG controller - (zero) viewDeadapp: (BOOL) animated {[Superodewepper: animated]; Static BOOL firstTime = Yes; If (first time) {contentView = zero; (UIView * v in self.view.subviews) {if ([v isKindOfClass: [NSClassFromString (@ "UINavigationTransitionView") class]]) {contentView = v; break; }} First Time = No; OrigFrame = contentView.frame; NoConnectionView.frame = CGRectMake (0, self.navigationBar.frame.origin.y + self.navigationBar.frame.size.height, 320, 20); } [Self Adjustment Organizer: No With Animation: No]; } - (zero) adjustmentTok Connection: (BOOL) is connection with animation: (BOOL) animation {if (connection is) {[noConnectionView removeFromSuperview]; ContentView.frame = originFrame; } And {{self.view addSubview: noConnectionView]; ContentView.frame = CGRectMake (0, origFrame.origin.y + 20, 320, origFrame.size.height-20); }}

Create your UIView and set its frame Some such as (0, 0, self.view.frame.size.witdh, 40)

Use to add a view to your UIViewController .

myView.frame.size.height with vertical offset, move your elements down in your main view .

You can get all this with such questions. If you need more help, then you should be more precise about the effort you have made, and what does not work.
