在ios开发过程中,总是会遇到一段话需要给不同的颜色以及不同字的大小,这个时候会使用到NSMutableAttributedString,以下是我自己写的一段代码,大家看看吧(复制可以直接跑).

上码:

UILabel *inLabel = [[UILabel alloc]initWithFrame:CGRectMake(95, 64, 190, 70)];

inLabel.backgroundColor = [UIColor cyanColor];

//infoLabel.backgroundColor = [UIColor clearColor];

inLabel.textAlignment = NSTextAlignmentLeft;

inLabel.font = [UIFont systemFontOfSize:13];

inLabel.numberOfLines = 0;

// infoLabel.textColor = [UIColor cyanColor];

[self.view addSubview:inLabel];

NSString *inString = @"连续签到1天得10积分；\n连续签到2天得15积分；\n连续签到3天及以上得20积分；\n注: 若连续签到终端则重新计算";

// NSString * ha = [NSString stringWithFormat:@"注:"];

// NSString * ha2 = [NSString stringWithFormat:@"1"];

// NSString * ar = [NSString stringWithFormat:@"%@,%@",ha2]

// NSRange infoRange = [infoString rangeOfString:@"注:"];

NSMutableAttributedString *inATString = [[NSMutableAttributedStringalloc]initWithString:inString ];

// [infoATString addAttribute:(NSString *)NSForegroundColorAttributeName

// value:(id)[UIColor redColor]

// range:infoRange];

[inATString addAttribute:NSForegroundColorAttributeName value:[UIColoryellowColor] range:NSMakeRange(4, 1)];

[inATString addAttribute:NSForegroundColorAttributeName value:[UIColoryellowColor] range:NSMakeRange(7,2)];

// NSRange range = NSMakeRange(infoString.length-1, 1);

//[infoATString addAttribute:(NSString *)kCTFontAttributeName value:(id)[UIFont systemFontOfSize:10] range:range];

[inLabel setAttributedText:inATString];
