目前我在 iPhone 应用程序中工作，使用 UIImageView 在屏幕上设置背景图像，然后在 UIImageView 中添加 UITextField，然后我运行应用程序，UITextField 无法启用，如何启用它？请帮我

提前致谢

我试过这个：

UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
imageView.image=[UIImage imageNamed:@"2ndscreenback.png"];

Daystext =[[UITextField alloc]initWithFrame:CGRectMake(57, 122, 171, 31)];
Daystext.borderStyle=UITextBorderStyleRoundedRect;
Daystext.delegate=self;
Daystext.userInteractionEnabled=YES;
[imageView addSubview:Daystext];
[self.view addSubview:imageView];

只需在您的代码中添加以下行

imageView.userInteractionEnabled = YES;

像这样的意思

UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
imageView.image=[UIImage imageNamed:@"2ndscreenback.png"];

Daystext =[[UITextField alloc]initWithFrame:CGRectMake(57, 122, 171, 31)];
Daystext.borderStyle=UITextBorderStyleRoundedRect;
Daystext.delegate=self;
Daystext.userInteractionEnabled=YES;
imageView.userInteractionEnabled = YES;
[imageView addSubview:Daystext];
[self.view addSubview:imageView];

试试这样

UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
imageView.image=[UIImage imageNamed:@"2ndscreenback.png"];
imageView.userInteractionEnabled=YES;
[self.view addSubview:imageView];

Daystext =[[UITextField alloc]initWithFrame:CGRectMake(57, 122, 171, 31)];
Daystext.borderStyle=UITextBorderStyleRoundedRect;
Daystext.delegate=self;

[imageView addSubview:Daystext];

您可以在 imageview 上获取文本字段....

我认为最好为您的 UITextFild 设置背景图像，如下所示：

myTextField.borderStyle = UITextBorderStyleNone;
myTextField.background = [UIImage imageNamed:@"back.png"];

或者像这样

UIImageView *myView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"back.png"]];
[myTextField  setRightView:myView];
[myTextField  setRightViewMode:UITextFieldViewModeAlways];

试试这个。希望它对你有用！
