如何为状态UIControlStateHighlighted设置按钮标签文本颜色 [英] How to set the buttons label text color for state UIControlStateHighlighted

问题描述

我正在创建一个iPhone应用程序，其中我有一个自定义按钮。我通过创建标签并将其添加为子视图来设置按钮标题。现在当按钮突出显示时，我想更改标签文本颜色。

I am creating an iPhone application in which i have a custom button. i have set the buttons title by creating a Label and adding it as subview. now when the button is highlighted i want to change the labels text color.

这是我的代码，

UIButton *button1= [UIButton buttonWithType:UIButtonTypeCustom];
    [button1 setFrame:CGRectMake(68,162, 635, 101)];    
    [button1 setImage:[UIImage imageNamed:@"startwithouttext.png"] forState:UIControlStateNormal];
    [button1 setImage:[UIImage imageNamed:@"startactivewithouttext.png"] forState:UIControlStateHighlighted];

   UILabel *buttonLabel = [[UILabel alloc]  initWithFrame:CGRectMake(button1.bounds.origin.x+50, button1.bounds.origin.y+20, button1.bounds.size.width-100, button1.bounds.size.height-40)];

    [buttonLabel setFont:[UIFont fontWithName:@"Helvetica" size:28]];
    buttonLabel.backgroundColor=[UIColor clearColor];
    buttonLabel.textColor=[UIColor colorWithRed:83.0/255.0 green:83.0/255.0 blue:83.0/255.0 alpha:1.0];
    buttonLabel.highlightedTextColor=[UIColor whiteColor];
    buttonLabel.text = @"Long text string";
    [button1 addSubview:buttonLabel];
    [button1 bringSubviewToFront:buttonLabel];
    [button1 setContentVerticalAlignment:UIControlContentVerticalAlignmentCenter];
    [button1 setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];
    [button1 addTarget:self action:@selector(button1clicked:) forControlEvents:

[mainView button1];   

当按钮突出显示时，任何正文都可以帮我改变文字颜色吗？

can any body help me to change the text color when the button is highlighted?

推荐答案

在StackOverflow上的另一个问题中找到答案：

Found the answer in a different question on StackOverflow: UIButton color issues

[button1 setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];

如果您可以在不创建Label的情况下工作并将其添加为上面提到的子视图。

This is if you can work without creating a Label and adding it as subview as you mention above.
