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.

iOS ScreenShot 1

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

Used in Production

Requirements

  • iOS 4.3 or later
  • ARC

Usage

Instance

NJKWebViewProgress
and set
UIWebViewDelegate
. If you set
webViewProxyDelegate
,
NJKWebViewProgress
should perform as a proxy object.
_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];
}
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:
-(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.
