IOS 7 uses Uiscreenedgepangesturerecognizer to achieve swipe to pop effects

When iOS 7 is not yet released, various apps implement various swipe to pop effects, such as.

On iOS 7, as long as it is a system-compliant navigation structure: [That is, the root view is controlled by the navigation controller]

will be able to have the original beautiful effect:

Unfortunately, the current project code does not follow the navigation structure of the iOS system, making it impossible to exploit this benefit. So I'm thinking about using the new Uiscreenedgepangesturerecognizer gesture:

1- (void) Viewwillappear: (BOOL) Animated2 {3     if(System_version_greater_than_or_equal_to (@"7.0")) {4Uiscreenedgepangesturerecognizer *left2rightswipe =[[Uiscreenedgepangesturerecognizer alloc]5 initwithtarget:self6 Action: @selector (handleswipegesture:)];7 [Left2rightswipe setdelegate:self];8 [Left2rightswipe Setedges:uirectedgeleft];9 [Self.view addgesturerecognizer:left2rightswipe];Ten     } One  A } -  -  the- (void) Handleswipegesture: (Uiscreenedgepangesturerecognizer *) Gesturerecognizer - { - [Self.navigationcontroller Popviewcontrolleranimated:yes]; -}

This also implements the effect of the relevant return function, in particular, related to gesture-related interference problems, see blog: http://blog.csdn.net/jasonblog/article/details/16867587
