实现代码
#import "ViewController.h"
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UILabel *label1;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
//创建富文本对象
NSMutableAttributedString *attrrbute1 = [[NSMutableAttributedString alloc] initWithString:self.label1.text];
//设置字体大小
[attrrbute1 addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:29] range:NSMakeRange(5, 4)];
//设置字体颜色
[attrrbute1 addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(10, 4)];
//设置字体背景颜色
[attrrbute1 addAttribute:NSBackgroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(15, 5)];
//设置删除线
[attrrbute1 addAttribute:NSStrikethroughStyleAttributeName value:[NSNumber numberWithInteger:1] range:NSMakeRange(31, 10)];
//设置下划线
[attrrbute1 addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:2] range:NSMakeRange(40, 10)];
//一下两者必须结合使用
//设置空心字颜色
[attrrbute1 addAttribute:NSStrokeColorAttributeName value:[UIColor orangeColor] range:NSMakeRange(50, 10)];
//空心字边框颜色
[attrrbute1 addAttribute:NSStrokeWidthAttributeName value:[NSNumber numberWithInteger:1] range:NSMakeRange(50, 10)];
//将富文本属性添加到控件上
self.label1.attributedText = attrrbute1;
}
