IOS--UIWebView加载进度条（NJKWebViewProgress）

# NJKWebViewProgress NJKWebViewProgress is a progress interface library for UIWebView. Currently, UIWebView doesn't have official progress interface. You can implement progress bar for your in-app browser using this module. <img src="https://raw.github.com/ninjinkun/NJKWebViewProgress/master/DemoApp/Screenshot/screenshot1.png" alt="iOS ScreenShot 1" width="240px" style="width: 240px;" /> NJKWebViewProgress doesn't use CocoaTouch's private methods. It's AppStore safe. # Used in Production - [Yahoo! JAPAN](https://itunes.apple.com/app/yahoo!-japan/id299147843?mt=8) - [Facebook](https://itunes.apple.com/app/facebook/id284882215?mt=8‎) # Requirements - iOS 4.3 or later - ARC # Usage Instance `NJKWebViewProgress` and set `UIWebViewDelegate`. If you set `webViewProxyDelegate`, `NJKWebViewProgress` should perform as a proxy object. ```objc _progressProxy = [[NJKWebViewProgress alloc] init]; // instance variable webView.delegate = _progressProxy; _progressProxy.webViewProxyDelegate = self; _progressProxy.progressDelegate = self; ``` When UIWebView start loading, `NJKWebViewProgress` call delegate method and block with progress. ```objc -(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress { [progressView setProgress:progress animated:NO]; } ``` ```objc progressProxy.progressBlock = ^(float progress) { [progressView setProgress:progress animated:NO]; }; ``` You can determine the current state of the document by comparing the `progress` value to one of the provided constants: ```objc -(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress { if (progress == NJKInteractiveProgressValue) { // The web view has finished parsing the document, // but is still loading sub-resources } } ``` This repository contains iOS 7 Safari style bar `NJKWebViewProgressView`. You can choose `NJKWebViewProgressView`, `UIProgressView` or your custom bar. # Install ## CocoaPods ``` pod 'NJKWebViewProgress' ``` # License [Apache]: http://www.apache.org/licenses/LICENSE-2.0 [MIT]: http://www.opensource.org/licenses/mit-license.php [GPL]: http://www.gnu.org/licenses/gpl.html [BSD]: http://opensource.org/licenses/bsd-license.php [MIT license][MIT].
