iphone - Can not load HTML String in UIWebview

Question

I am trying to show a HTML String in uiwebview and it give me the error below:

 **-[__NSArrayI dataUsingEncoding:]: unrecognized selector sent to instance 0x75caf40

here is the code:

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

if I copy the output string from NSLog and put it in loadHTMLString its fine but if I put "desc" which is the same I will get the error. I have not idea what could have gone wrong. Thanks

Answer 1

Try the following statement.

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

And please check whether the "self.jobdescription" is a UIWebView object or not.

Answer 2

Seems like desc is not string but array. Add NSLog(@"%@", NSStringFromClass([desc class])); to ensure.
