无法更改UILabel文本颜色

Question

我想更改UILabel文本颜色,但我无法更改颜色,这就是我的代码的样子.

UILabel *categoryTitle = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 46, 16)];
categoryTitle.text = @"abc";
categoryTitle.backgroundColor = [UIColor clearColor];
categoryTitle.font = [UIFont systemFontOfSize:12];
categoryTitle.textAlignment = UITextAlignmentCenter;
categoryTitle.adjustsFontSizeToFitWidth = YES;
categoryTitle.textColor = [UIColor colorWithRed:188 green:149 blue:88 alpha:1.0];
[self.view addSubview:categoryTitle];
[categoryTitle release];

标签文本颜色为白色,而不是我的自定义颜色.

感谢您的帮助.

Answer 1

UIColor的RGB分量在0和1之间缩放,而不是255.

尝试

categoryTitle.textColor = [UIColor colorWithRed:(188/255.f) green:... blue:... alpha:1.0];

在Swift中:

categoryTitle.textColor = UIColor(red: 188/255.0, green: ..., blue: ..., alpha: 1)

Answer 2

可能是更好的方法

UIColor *color = [UIColor greenColor];
[self.myLabel setTextColor:color];

因此我们有彩色文字
