无法在UIWebview中加载HTML字符串

Question

我想在uiwebview中显示一个HTML字符串，它给出了以下错误：

 **-[__NSArrayI dataUsingEncoding:]: unrecognized selector sent to instance 0x75caf40
2013-09-17 10:26:48.774 iphoneApp[9395:2903] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI dataUsingEncoding:]: unrecognized selector sent to instance 0x75caf40'
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception*
*emphasized text**

这是代码：

NSString *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSString *desc = [json valueForKey:@"description"];
NSLog(@"%@",desc);
[self.jobdescription loadHTMLString:desc baseURL:nil];

如果我从NSLog复制输出字符串并将其放在loadHTMLString中它很好但如果我把“desc”相同，我将得到错误。我不知道会出现什么问题。谢谢

Answer 1

请尝试以下语句。

[self.jobdescription loadHTMLString:[NSString stringWithFormat:@"%@",desc] baseURL:nil];

请检查“self.jobdescription”是否是UIWebView对象。

Answer 2

好像desc不是字符串而是数组。添加NSLog(@"%@", NSStringFromClass([desc class]));以确保。
