Highlight just the text in a UILabel

Question

I\'m attempting to set the background color/highlight just the text within a UILabel. The issue is that the line breaks and spaces added to the UILabel

I've faced same issue and found out easier solution without huge performance costs. You can simply add TTTAttributedLabel to your project.

My demo project for the question:

#import "TTTAttributedLabel.h"

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    UILabel *label1 = [UILabel new];
    label1.textAlignment = NSTextAlignmentCenter;
    label1.numberOfLines = 0;
    label1.frame = CGRectMake(20, 0, CGRectGetWidth(self.view.frame) - 40, CGRectGetHeight(self.view.frame) / 2.0);
    [self.view addSubview:label1];

    TTTAttributedLabel *label2 = [TTTAttributedLabel new];
    label2.textAlignment = NSTextAlignmentCenter;
    label2.numberOfLines = 0;
    label2.frame = CGRectMake(20, CGRectGetHeight(self.view.frame) / 2.0, CGRectGetWidth(self.view.frame) - 40, CGRectGetHeight(self.view.frame) / 2.0);
    [self.view addSubview:label2];

    NSDictionary *attributes = @{NSBackgroundColorAttributeName:[UIColor blackColor], NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont systemFontOfSize:32 weight:UIFontWeightBold]};
    NSAttributedString *string = [[NSAttributedString alloc] initWithString:@"Some very long string which can contain newlines and some other stuff" attributes:attributes];
    label1.attributedText = string;
    label2.text = string;
}
