一个lable显示不同的字体颜色

#pragma mark ---- 固定字体颜色大小处理

- (NSMutableAttributedString *)attrStrFrom:(NSString *)titleStr numberStr:(NSString *)numberStr

{

NSMutableAttributedString *arrString = [[NSMutableAttributedString alloc]initWithString:titleStr];

// 设置前面几个字串的格式:蓝色 16.0f字号

[arrString addAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15.0f],

NSForegroundColorAttributeName:[UIColor redColor]

}

range:[titleStr rangeOfString:numberStr]];

return arrString;

}

[lable setAttributedText:[self attrStrFrom:[NSString stringWithFormat:@"预计%@后发货",timeString] numberStr:timeString]];
