UIButton颜色问题 [英] UIButton color issues

问题描述

如何更改UIButton上文本的颜色。这是我目前的代码：

How can I change the color of the text on my UIButton. Here is my current code:

    UIButton *b1 = [[UIButton alloc] init];
    b1.frame = CGRectMake(280,395,30,30);
    [[b1 layer] setCornerRadius:8.0f];
    [[b1 layer] setMasksToBounds:YES];
    [[b1 layer] setBorderWidth:1.0f];
    [[b1 layer] setBackgroundColor:[botCol CGColor]];
    b1.titleLabel.font = [UIFont boldSystemFontOfSize:24];
    [b1 setTitleColor:[UIColor redColor] forState:UIControlEventAllEvents];
    [b1 addTarget:self action:@selector(NextButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [b1 setTitle:@">" forState:UIControlStateNormal];
    [self.view addSubview:b1];

这是它的样子（忽略背景颜色和东西）：

Here is what it looks like (ignore the background color and stuff):

现在，我怎样才能让箭头变红？如上所示，我已经有以下内容：

Now, how can I get the arrow to be red? As you see above, I already have the following:

[b1 setTitleColor:[UIColor redColor] forState:UIControlEventAllEvents];

但它不起作用。

推荐答案

尝试设置单个事件，例如：

Try setting the individual events, such as:

[b1 setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
