objective-c - UIButton不显示使用[UIButton名称setTitle]设置的文本

对于以下代码(UIButton未连接到IBOutlet的情况):

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];

在.h文件中声明了PlayButton指针。当我使用此代码时，按钮文本不会出现，但是按钮会显示图像。如何显示文字？

最佳答案

尝试这个 :

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];

我认为您忘了声明按钮的类型
