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.
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'
.
It's C style formatting. %nd means the width is n.
check following code.
NSLog(@"%10@",[NSString stringWithFormat:@"%10@",@"test"]);
NSLog(@"%@",[NSString stringWithFormat:@" %@",@"test"]);
NSLog(@"%10@", @"test");
NSLog(@"%10s", [@"test" cStringUsingEncoding:[NSString defaultCStringEncoding]]);
NSLog(@"%10d", 1);
NSString *str = @"test";
int padding = 10-[str length]; //6
if (padding > 0)
{
NSString *pad = [[NSString string] stringByPaddingToLength:padding withString:@" " startingAtIndex:0];
str = [pad stringByAppendingString:str];
}
NSLog(@"%@", str);
