的UIButton不diplay文本与[UIButtonname的setTitle]

Question

对于以下代码（其中的UIButton未连接到一个IBOutlet）设置：

UIImage *defaultButton = [UIImage imageNamed:@"StandardButton.png"]; 
PlayButton = [[UIButton alloc] initWithFrame:CGRectMake(250, 50, 220, 50)]; 
[PlayButton setImage:defaultButton forState:UIControlStateNormal]; 
[PlayButton setTitle:@"PlayButton" forState:UIControlStateNormal]; 
[PlayButton addTarget:self action:@selector(StoryModeReleased:)forControlEvents:UIControlEventTouchUpInside]; 
[self.view addSubview:PlayButton]; 

的PLAYBUTTON指针在.h文件声明。当我使用此代码时，按钮文本不会显示，但按钮会显示图像。我怎样才能让文字显示？

Answer 1

试试这个：

PlayButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
UIImage *defaultButton = [UIImage imageNamed:@"StandardButton.png"]; 
PlayButton.frame = CGRectMake(250, 50, 220, 50)]; 
[PlayButton setImage:defaultButton forState:UIControlStateNormal]; 
[PlayButton setTitle:@"PlayButton" forState:UIControlStateNormal]; 
[PlayButton addTarget:self action:@selector(StoryModeReleased:)forControlEvents:UIControlEventTouchUpInside]; 
[self.view addSubview:PlayButton]; 

我想你忘记了声明按钮的类型
