IOS开发－UI学习－NSMutableAttributedString（带属性的字符串）的使用
带属性的字符串：
1 NSString *aa = @"hellochinaIloveYou!"; 2 NSMutableAttributedString *mas = [[NSMutableAttributedString alloc]initWithString:aa]; 3 4 // 设置字符串字属性 5 UIFont *font = [UIFont fontWithName:@"Arial" size:35.0f]; 6 [mas addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, 17)]; 7 // 设置字体颜色 8 [mas addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0, 15)]; 9 // 设置背景色 10 [mas addAttribute:NSBackgroundColorAttributeName value:[UIColor grayColor] range:NSMakeRange(0, 13)]; 11 // 设置字符间距 12 [mas addAttribute:NSKernAttributeName value:[NSNumber numberWithFloat:10.1] range:NSMakeRange(0, 9)]; 13 // 设置删除线线型 14 [mas addAttribute:NSStrikethroughStyleAttributeName value:[NSNumber numberWithInt:1] range:NSMakeRange(0, 19)]; 15 // 设置删除线颜色 16 [mas addAttribute:NSStrikethroughColorAttributeName value:[UIColor greenColor] range:NSMakeRange(0, 7)]; 17 // 设置字体倾斜 18 [mas addAttribute:NSObliquenessAttributeName value:[NSNumber numberWithFloat:0.6] range:NSMakeRange(0, 5)]; 19 // 拉伸字体 20 [mas addAttribute:NSExpansionAttributeName value:[NSNumber numberWithFloat:0.9] range:NSMakeRange(0, 3)]; 21 // 设置下划线 22 [mas addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(0, 7)]; 23 // 设置下划线颜色 24 [mas addAttribute:NSUnderlineColorAttributeName value:[UIColor whiteColor] range:NSMakeRange(0, 7)]; 25 // 设置搂空字体 26 [mas addAttribute:NSStrokeWidthAttributeName value:[NSNumber numberWithInt:12] range:NSMakeRange(0, 9)]; 27 // 搂空字体设置颜色 28 [mas addAttribute:NSStrokeColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 9)]; 29 // 设置阴影 30 NSShadow *shadow = [[NSShadow alloc]init]; 31 shadow.shadowBlurRadius = 10; 32 shadow.shadowColor = [UIColor colorWithRed:0.502 green:0.023 blue:0.134 alpha:1.000]; 33 shadow.shadowOffset = CGSizeMake(-0.1, 0.1); 34 [mas addAttribute:NSShadowAttributeName value:shadow range:NSMakeRange(0, 19)]; 35 // 设置印刷字体 36 [mas addAttribute:NSTextEffectAttributeName value:NSTextEffectLetterpressStyle range:NSMakeRange(0, 6)]; 37 38 39 40 41 42 43 UILabel * label = [[UILabel alloc]initWithFrame:CGRectMake(0, 200, 418, 100)]; 44 // label.text = mas.string; 45 label.attributedText =mas; 46 47 [self.view addSubview:label];
