的UIButton不diplay文本與[UIButtonname的setTitle]

Question

對於以下代碼（其中的UIButton未連接到一個IBOutlet）設置：

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指針在.h文件聲明。當我使用此代碼時，按鈕文本不會顯示，但按鈕會顯示圖像。我怎樣才能讓文字顯示？

Answer 1

試試這個：

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]; 

我想你忘記了聲明按鈕的類型
