遇到的一些奇葩问题

1.字符串直接赋值在block中不能用

 lHtml1=[NSString stringWithFormat:@"【%@】%@: %@",self.appNameString,self.titleLabel.text,self.urlString];

要给其分配地址才行

 lHtml1 = [[NSString alloc]initWithString:[NSString stringWithFormat:@"【%@】%@: %@",self.appNameString,self.titleLabel.text,self.urlString]];

2.webView直接用地址请求有时候有用有时候又不行

 [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.urlString]]];

换一种形式可行

 NSMutableURLRequest* req=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:self.urlString] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10000];

  [req setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];

    [webView loadRequest:req];
