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];
