问题描述
我的代码中有这个 switch 语句:
I have this switch statement in my code:
switch(buttonIndex){
case 0:
[actionSheet dismissWithClickedButtonIndex:buttonIndex animated:YES];
break;
case 1:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:[imagePicker autorelease] animated:YES];
break;
default:
[self openEmailViewInViewController:self];
}
在案例 1 中的 UIImagePickerController 实例化中,我收到了一个错误:
And at the UIImagePickerController instantiation in Case 1 I am getting an error:
error:expected expression before 'UIImagePickerController'
我不知道我做错了什么.想法?
and I have no idea what I am doing wrong. Thoughts?
而且 buttonIndex 是一个 NSInteger
Oh, and buttonIndex is an NSInteger
推荐答案
不能在 case 标签后面声明变量.
