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
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**

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

Check structure of data you get - from error message follows that value for key "description" is array, not string — Vladimir

but how is it possible. I am getting json data as string and save the value for key in NSString. I dont even have Array in there ? here is the value for key "description" that I get from nslog:"Arizona Academic Family Medicine One Million+ Metro Population Our beautiful Southwest" — John wilson

It is hard to say why without seeing all your code and all your data. Try to check what type desc object actually has — Vladimir

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.

Thanks Satya, it shows the String in the UIWebView but with parentheses and double quotes, is there any way I can eliminate them ?

Satya Over a year ago

Is it displaying those quotes & parentheses while directly loading with out using "desc" variable?

John wilson Over a year ago

I just copied the code that you sent and it shows them !! also, Yakymiv says that desc might be an array. He is right. I change my code to: NSString *desc = [json valueForKey:@"description"]; NSString *myArrayString = [desc description]; //NSLog(@"%@",myArrayString); // NSLog(@"%@", NSStringFromClass([myArrayString class])); [self.jobdescription loadHTMLString:myArrayString baseURL:nil]; it shows the string just fine but with parentheses !!!

then do this, replace the parentheses with empty strings. Like myArrayString = [myArrayString stringByReplacingOccurrencesOfString:@"(" withString:@""]; same for right parentheses also

Got it. Thanks so much. Here is my code for reference:NSString *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]; NSString *desc = [json valueForKey:@"description"]; NSString *myArrayString = [desc description]; NSString *myArrayString2 = [[myArrayString stringByReplacingOccurrencesOfString:@")" withString:@""] stringByReplacingOccurrencesOfString:@"(" withString:@""]; [self.jobdescription loadHTMLString:myArrayString2 baseURL:nil];

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