Question

I would like to be able to right align a string using spaces. I have to be able to use the stringWithFormat: method.

So far I have tried the recommended format and it does not seem to work: [NSString stringWithFormat:@"%10@",@"test"].

I would expect this to return a string that has six spaces followed by “test” but all I am getting is “test” with no spaces.

Answer 1

It appears that stringWithFormat ignores the sizing requests of the %@ format specifier. However, %s specifier works correctly:

NSString *test = @"test";
NSString *str = [NSString stringWithFormat:@"%10s", [test cStringUsingEncoding:NSASCIIStringEncoding]];
NSLog(@"'%@'", str);

This prints ' test'.
