NSMutableAttributedString繼承於NSAttributedString(帶屬性的字符串)可以簡單快速實現富文本的效果;很少說直接上效果圖和代碼,通俗易懂:html
(一)效果圖:ios
(二)代碼:app
1 UILabel *testLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 100, [[UIScreen mainScreen] bounds].size.width, 30)]; 2 3 testLabel.textAlignment = NSTextAlignmentCenter; 4 5 NSMutableAttributedString *AttributedStr = [[NSMutableAttributedString alloc]initWithString:@"猴年大吉,新春快樂!"]; 6 7 [AttributedStr addAttribute:NSFontAttributeName 8 9 value:[UIFont systemFontOfSize:26.0] 10 11 range:NSMakeRange(2, 2)]; 12 13 [AttributedStr addAttribute:NSForegroundColorAttributeName 14 15 value:[UIColor redColor] 16 17 range:NSMakeRange(2, 2)]; 18 19 [AttributedStr addAttribute:NSBackgroundColorAttributeName 20 21 value:[UIColor redColor] 22 23 range:NSMakeRange(7, 2)]; 24 25 testLabel.attributedText = AttributedStr; 26 27 [self.view addSubview:testLabel];
(三)常見的屬性及說明:字體
NSFontAttributeName // 字體spa
NSParagraphStyleAttributeName // 段落格式 3d
NSForegroundColorAttributeName // 字體顏色code
NSBackgroundColorAttributeName // 背景顏色htm
NSStrikethroughStyleAttributeName // 刪除線格式blog
NSUnderlineStyleAttributeName //下劃線格式繼承
NSStrokeColorAttributeName //刪除線顏色
NSStrokeWidthAttributeName //刪除線寬度
NSShadowAttributeName //陰影
