Question

I have an NSString and fail to apply the following statement:

NSString *myString = @"some text";
[myString stringByAppendingFormat:@"some text = %d", 3];

no log or error, the string just doesn’t get changed. I already tried with NSString (as documented) and NSMutableString.

any clues most welcome.

Answer 1

I would suggest correcting to (documentation):

NSString *myString = @"some text";
myString = [myString stringByAppendingFormat:@" = %d", 3];

From the docs:

Returns a string made by appending to the receiver a string constructed from a given format string and the following arguments.
