UILabel TEXT的两种颜色

本文介绍了UILabel TEXT的两种颜色的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想为 UILabel的文本设置两种颜色。我尝试了 TTTRegexAttributedLabel ，但它抛出了未知类型错误。

I want to set two colors for UILabel's text. I tried TTTRegexAttributedLabel, but it is throwing unknown type error.

我也尝试过以下代码。但它在settext崩溃。

I tried following code too. But it is crashing at settext.

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Hello. That is a test attributed string."]; [str addAttribute: @"Hello" value:[UIColor yellowColor] range:NSMakeRange(3,5)]; [str addAttribute:@"That" value:[UIColor greenColor] range:NSMakeRange(10,7)]; [str addAttribute:@"Hello" value:[UIFont fontWithName:@"HelveticaNeue-Bold" size:20.0] range:NSMakeRange(20, 10)]; [syncStatusLabel setText:(NSString *)str];

有没有其他方法可以为单个UILabel文本设置多种颜色？

Is there any other way to set multiple colors for single UILabel text?

推荐答案

你可以设置文字颜色，如下图所示..

you can set text color with pattern image like bellow..

[yourLable setTextColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"yourImageName"]]];

并使用此波纹管代码设置不同的颜色..请查看详细配合的教程..

and also set different color with this bellow code.. please check tutorial with detail mate..

NSString *test = @"Hello. That is a test attributed string."; CFStringRef string = (CFStringRef) test; CFMutableAttributedStringRef attrString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0); CFAttributedStringReplaceString (attrString,CFRangeMake(0, 0), string); /* Note: we could have created CFAttributedStringRef which is non mutable, then we would have to give all its attributes right when we create it. We can change them if we use mutable form of CFAttributeString. */ //Lets choose the colors we want to have in our string CGColorRef _orange=[UIColor orangeColor].CGColor; CGColorRef _green=[UIColor greenColor].CGColor; CGColorRef _red=[UIColor redColor].CGColor; CGColorRef _blue=[UIColor blueColor].CGColor; //Lets have our string with first 20 letters as orange //next 20 letters as green //next 20 as red //last remaining as blue CFAttributedStringSetAttribute(attrString, CFRangeMake(0, 20),kCTForegroundColorAttributeName, _orange); CFAttributedStringSetAttribute(attrString, CFRangeMake(20, 20),kCTForegroundColorAttributeName, _green); CFAttributedStringSetAttribute(attrString, CFRangeMake(40, 20),kCTForegroundColorAttributeName, _red); CFAttributedStringSetAttribute(attrString, CFRangeMake(60, _stringLength-61),kCTForegroundColorAttributeName, _blue);
