label大家玩的都比較多了.下面我就分享一下我用到的比較實用的幾個例子.

1.自動換行

UILabel * WithdrawalRules = [[UILabel alloc] init];

指定numberOfLines =0 ?然后在 字符串里需要換行的地方 加\n就可以了.

WithdrawalRules.numberOfLines = 0;

WithdrawalRules.text? =@"提現(xiàn)規(guī)則：\n1、當天提現(xiàn)最多不可超過3次；\n2、每次提現(xiàn)金額不低于10元，不高于100元。" ;

2.修改label的字間距

NSString *str = @"親愛的手環(huán)用戶!若是您的手環(huán)刷卡體驗不佳,建議嘗試更換手環(huán)參數(shù)模式,此參數(shù)目前僅在南京地區(qū)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的行間距

-(NSAttributedString *)getAttributedStringWithString:(NSString *)string lineSpace:(CGFloat)lineSpace {

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

paragraphStyle.lineSpacing = lineSpace; // 調(diào)整行間距

NSRange range = NSMakeRange(0, [string length]);

[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];

return attributedString;

}

4.添加下劃線

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"點擊購買手環(huán)"];

NSRange strRange = {0,[str length]};

[str addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:NSUnderlineStyleSingle] range:strRange];

5.字體的顏色

[str addAttribute:NSForegroundColorAttributeName value:rgbaColor(220, 221, 217, 1) range:NSMakeRange(0, str.length)];
