这里是js,主要目的实现对url的获取
static NSString * const jsGetImages =
@"function getImages(){\
var objs = document.getElementsByTagName(\"img\");\
var imgScr = '';\
for(var i=0;i
imgScr = imgScr + objs[i].src + '+';\
};\
return imgScr;\
};";
[webView stringByEvaluatingJavaScriptFromString:jsGetImages];//注入js方法
NSString *urlResurlt = [webView stringByEvaluatingJavaScriptFromString:@"getImages()"];
NSArray *Imgarr = [urlResurlt componentsSeparatedByString:@"+"];
