UIWebView的警告，目标C

Question

我得到这样的警告：local declaration of webView hides instance variable

-(void)webViewDidFinishLoad:(UIWebView *)webView 
{ 
    [webView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"]; 
    [activityIndicator stopAnimating]; 
} 

Answer 1

在你的类，你已经有一个名为web视图变量。您可以更改其名称或像这样的东西改变你的方法签名：

-(void)webViewDidFinishLoad:(UIWebView *)aWebView { 
    [aWebView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"]; 
    [activityIndicator stopAnimating]; 
} 

这应该是不错的:)
