iOS UILabel换行同时修改字体大小颜色

UIButton *onlyPriceBtn = [UIButton buttonWithType:UIButtonTypeCustom];

onlyPriceBtn.layer.borderColor = [HuConfigration uiColorFromString:@"#F0493D"].CGColor;;

onlyPriceBtn.layer.borderWidth = 0.5f;

onlyPriceBtn.layer.cornerRadius = 4;

onlyPriceBtn.layer.masksToBounds = YES;

onlyPriceBtn.frame = CGRectMake(15, CGRectGetMaxY(titleLabel.frame)+15, HHBWIDTH - 30, 60);

[self.bgView addSubview:onlyPriceBtn];

UILabel *btnTitleLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 60)];

btnTitleLabel.center = onlyPriceBtn.center;

btnTitleLabel.textColor = kHuColor(#A5A5A5);

btnTitleLabel.font = [UIFont customFontSize:12];

btnTitleLabel.numberOfLines = 0;

btnTitleLabel.text = @"独享价30.0元\n购买后仅供自己观看学习";//使用斜杠一定不要忘记写numberOfLines 否则无效

btnTitleLabel.textAlignment = NSTextAlignmentCenter;

NSMutableAttributedString *attributer = [[NSMutableAttributedString alloc]initWithString:btnTitleLabel.text];

[attributer addAttribute:NSForegroundColorAttributeName

value:kHuColor(#F0493D)

range:NSMakeRange(0, 8)];

[attributer addAttribute:NSFontAttributeName

value:[UIFont customFontSize:16]

range:NSMakeRange(0, 8)];

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];//调整行间距

[paragraphStyle setLineSpacing:4];

[attributer addAttribute:NSParagraphStyleAttributeName

value:paragraphStyle

range:NSMakeRange(0, btnTitleLabel.text.length)];

[paragraphStyle setAlignment:NSTextAlignmentCenter];//为了美观调整行间距，但是当调整行间距时上面设置的居中不能用看 所以要加这一句 [paragraphStyle setAlignment:NSTextAlignmentCenter] 不然没有居中效果

btnTitleLabel.attributedText = attributer;

[self.bgView addSubview:btnTitleLabel];
