UIButton 标题消失 [英] UIButton title disappears

问题描述

我有一个 ViewController，里面有一个 UIButton.当我点击时，按钮上的文字消失了.我为所有状态添加了所有 setTitle，但它继续消失.有什么想法吗?

I have a ViewController with an UIButton inside. When I clicked, the text on the button disappeared. I add all the setTitle for all states, but it continues disappearing. Any idea?

这是我的代码的一部分:

This is a part of my code:

@interface AddCardViewController : UITableViewController <UITextFieldDelegate>{
UIButton *commit;
    ......

@implementation AddCardViewController

- (void)viewDidLoad{

    self.commit = [UIButton buttonWithType: UIButtonTypeCustom];

    [self setCommitProperties];

    [self.view addSubview:commit];

 .........}



- (void) setCommitProperties{

   CGRect frameTable = self.tableView.frame;

   CGRect frame = CGRectMake(frameTable.origin.x + 10, 140, frameTable.size.width - 20, 40);

   commit.frame = frame;

   [commit setBackgroundColor : [UIColor whiteColor]];

   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateNormal];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateSelected];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateHighlighted];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateApplication];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateReserved];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateDisabled];

    [commit addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchDown];    

   UIColor *color = [[[PersonalizationManager alloc] init] getColor: @"AddCardViewController" :@"Commit_Title"]; 

   [commit.titleLabel setTextColor: color];

   color = [[[PersonalizationManager alloc] init] getColor: @"AddCardViewController" :@"Commit_Border"];

   [commit.layer setBorderColor:[color CGColor]];    
   [commit.layer setBorderWidth : 0.5f];
   [commit.layer setCornerRadius : 10.0f];
}

推荐答案

嗯，这很难确定，但是文字是不是因为颜色相同而看不到?我看到您为所有状态设置了文本，但您可能还想为所有状态设置颜色.

Well it's hard to say for sure, but is the text not visible because the color is the same? I see you set the text for all states but you may want to set the color for all states as well.

[commit setTextColor:[UIColor redColor] forState:UIControlStateSelected];
