So I extented UIWebView to support the gesture(now only go back gesture). 9 | 10 | 扩展了UIWebView，使其支持滑动手势返回（类似微信的In-App浏览器）。 11 | 12 | Safari里面除了点击‘前进’，‘后退’按钮，还可以通过滑动手势来前进和后退。 13 | 14 | 可惜UIWebView不支持这个手势，所以我扩展了UIWebView使其支持滑动手势返回。 15 | 16 | # Screenshot 17 | ![DLPanableWebView](images/demo.gif) 18 | 19 | # Requirements 20 | * IOS6.1 or later 21 | * ARC 22 | 23 | # Setup 24 | * Add 'DLPanableWebView' to your project. 25 | * If you are using CocoaPods: 26 | 27 | Add ```pod 'DLPanableWebView'``` to your [Podfile](http://cocoapods.org/) 28 | 29 | Run ```pod install``` 30 | * else 31 | 32 | Run ```git clone https://github.com/agdsdl/DLPanableWebView.git``` to download our code. 33 | 34 | Add 'DLPanableWebView.h' and 'DLPanableWebView.m' to your project. 35 | * Add #import 36 | ```objc 37 | #import "DLPanableWebView.h" 38 | ``` 39 | * Replace your 'UIWebView' to 'DLPanableWebView'. 40 | ```objc 41 | @interface WebViewController () 42 | @property (weak, nonatomic) IBOutlet DLPanableWebView *webView; 43 | @end 44 | ``` 45 | * That's it! 46 | 47 | Your web view now support pan back gesture. 48 | 49 | # Delegate 50 | [Optional] 51 | 52 | When navigate to the root page, and can not go back any more, ```DLPanableWebView``` will pass pan gesture to ```DLPanableWebViewHandler```. 53 | 54 | You can implement the ```DLPanableWebViewHandler``` protocol and handle the pan gesture if you want. 55 | For example, you can pop your WebViewController if you detect an pan back gesture(Check the demo). 56 | 57 | 58 | # License 59 | -------------------- 60 | The MIT License (MIT) 61 | -------------------------------------------------------------------------------- /images/demo.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/agdsdl/DLPanableWebView/4722c741fcf972c20679a4b915320837d4f8fff7/images/demo.gif --------------------------------------------------------------------------------
