iOS 加載js獲取webView中圖片url

- (void)webViewDidFinishLoad:(UIWebView *)webView {//這里是js，主要目的實現對url的獲取
    static  NSString * const jsGetImages =
    @"function getImages(){\ var objs = document.getElementsByTagName(\"img\");\
    var imgScr = '';\ for(var i=0;i<objs.length;i++){\ imgScr = imgScr + objs[i].src + '+';\ };\ return imgScr;\ };";
    [webView stringByEvaluatingJavaScriptFromString:jsGetImages];//注入js方法
    NSString *urlResurlt = [webView stringByEvaluatingJavaScriptFromString:@"getImages()"]; mUrlArray = [NSMutableArray arrayWithArray:[urlResurlt componentsSeparatedByString:@"+"]]; if (mUrlArray.count >= 2) { [mUrlArray removeLastObject]; } DLog(@"%@",mUrlArray); }

其中mUrlArray為可變數組，用來盛放web中的圖片url組。
