Create NSString by repeating another string a given number of times

There is a method called stringByPaddingToLength:withString:startingAtIndex::

[@"" stringByPaddingToLength:100 withString: @"abc" startingAtIndex:0]

Note that if you want 3 abc’s, than use 9 (3 * [@"abc" length]) or create category like this:

@interface NSString (Repeat)

- (NSString *)repeatTimes:(NSUInteger)times;

@end

@implementation NSString (Repeat)

- (NSString *)repeatTimes:(NSUInteger)times {
  return [@"" stringByPaddingToLength:times * [self length] withString:self startingAtIndex:0];
}

@end
