IOS page Jump Controller has a delay

The general controller has the delay is should our controller view is the bar load, and so we use the time will be loaded, all of us in the use of Uinavigationcongtroller, this method

[Self.navigationcontroller Pushviewcontroller:controller Animated:yes]; When you jump, the controller needs to load the views view. All will be delayed for a while. Workaround:

View.frame = CGRectMake (0, 0, Zxscreenw, zxscreenh), manually invoking the view's set method can be resolved.

Zxtakepicturecontroller *pic = [[Zxtakepicturecontroller alloc] init];

Pic.view.frame = CGRectMake (0, 0, Zxscreenw, zxscreenh);

Pic.view.backgroundColor = [Uicolor Whitecolor];

[Self.navigationcontroller pushviewcontroller:pic Animated:yes];
