label大家玩的都比较多了.下面我就分享一下我用到的比较实用的几个例子.
1.自动换行
UILabel * WithdrawalRules = [[UILabel alloc] init];
指定numberOfLines =0 然后在 字符串里需要换行的地方 加\n就可以了.
WithdrawalRules.numberOfLines = 0;
WithdrawalRules.text =@"提现规则：\n1、当天提现最多不可超过3次；\n2、每次提现金额不低于10元，不高于100元。" ;
2.修改label的字间距
NSString *str = @"亲爱的手环用户!若是您的手环刷卡体验不佳,建议尝试更换手环参数模式,此参数目前仅在南京地区有效。";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:str attributes:@{NSKernAttributeName:@(1.0)}];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [str length])];
alabel.attributedText = attributedString;
3.修改label的行间距
-(NSAttributedString *)getAttributedStringWithString:(NSString *)string lineSpace:(CGFloat)lineSpace {
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineSpacing = lineSpace; // 调整行间距
NSRange range = NSMakeRange(0, [string length]);
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
return attributedString;
}
4.添加下划线
NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"点击购买手环"];
NSRange strRange = {0,[str length]};
[str addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:NSUnderlineStyleSingle] range:strRange];
5.字体的颜色
[str addAttribute:NSForegroundColorAttributeName value:rgbaColor(220, 221, 217, 1) range:NSMakeRange(0, str.length)];
