推荐答案

试试这个，它适用于iOS 5.0及以上版本:(也是iOS 7）

Try this, It's Working Fine for iOS 5.0 and up: (iOS 7 also)

- (void)viewDidLoad
{

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setFont:[UIFont fontWithName:@"Helvetica" size:20]];

}

适用于iOS 8

- (void)viewDidLoad
    {

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setDefaultTextAttributes:@{
            NSFontAttributeName: [UIFont fontWithName:@"Helvetica" size:20],
      }];

    }
