Answer 1

To get all the error details:

NSError * err;
...
[NSString stringWithFormat:@"%@", err];

You could try the localizedDescription method, which returns a string.

More in the docs.

Answer 3

I found that there are three main methods to NSError:

• error (NSInteger)
• domain (NSString)
• userInfo (NSDictionary)

Answer 4

for folks new to objective c (me), following is example code that makes accepted answer from 'KennyTM' work ->

[self showAlertWithTitle:@"Error:" withMessage:error.localizedDescription];

Answer 5

-[NSError localizedDescription].

(Also, every ObjC object inherited from NSObject implements -description which returns an NSString.)
