如何将NSString对象传递给stringByAppendingFormat：

Question

How to pass a NSString object to stringByAppendingFormat in objective c.

I am able to append string as:

NSString *aString =[name stringByAppendingFormat:@"Hello"];

but its not being possible to use an object of NSString for appending for example in my case

NSString *aString =self.stringName;
NSString *resultString =[name stringByAppendingFormat:[NSString stringWithFormat:@"%@",aString]];

what has to be changed in the above code ?

Answer 1

When using stringByAppendingFormat you are going to need a format. If you just want to append you should use:

NSString *aString =self.stringName;
NSString *resultString =[name stringByAppendingString:aString];

or

NSString *aString =self.stringName;
NSString *resultString =[name stringByAppendingFormat:@"%@",aString];

Answer 2

Maybe you must try in this way ?

NSString *aString  = self.stringName;
NSString * tempStr = [NSString stringWithFormat:@"%@",aString];
NSString *resultString =[name stringByAppendingFormat:tempStr];
