NJKWebViewProgress is a progress interface library for UIWebView. Currently, UIWebView don't have official progress interface. You can implement progress bar for your in-app browser using this module.

NJKWebViewProgress don't use CocoaTouch's private methods. It's AppStore safe.

• iOS 4.3 or later
• ARC

Instance NJKWebViewProgress and set UIWebViewDelegate. If you set webViewProxyDelegate, NJKWebViewProgress should perform as a proxy object.

NJKWebViewProgress *progressProxy = [[NJKWebViewProgress alloc] init];
webView.delegate = progressProxy;
progressProxy.webViewProxyDelegate = self;
progressProxy.progressDelegate = self;

When UIWebView start loading, NJKWebViewProgress call delegate method and block with progress.

-(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress
{
    [progressView setProgress:progress animated:NO];
}

progressProxy.progressBlock = ^(float progress) {
    [progressView setProgress:progress animated:NO];
};
