我正在尝试在单击按钮时创建一个名为“添加注释”的简单弹出窗口，该弹出窗口有一个保存和取消按钮，用于保存用户创建的注释并取消弹出窗口。这是弹出课程
AddNotesPopUp.h

typedef enum AddNotesViewType
{
AddNotesPopUpSimple
}AddNotesPopUpType;
@protocol AddNotesDelegate<NSObject>
@optional
-(void)saveButtonClicked:(id) popUp;
-(void)cancelAddButtonClicked:(id)popUp;
@end
@interface AddNotesPopUp : UIView

[self.delegate saveButtonClicked:self];
}
- (IBAction)cancelButtonAction:(id)sender {

@end
这就是我在视图控制器按钮操作中调用弹出窗口的方式
- (IBAction)addNotes:(id)sender {
AddNotesPopUp *pop=[[AddNotesPopUp alloc] initWithDelegate:self type:AddNotesPopUpSimple];
[pop show];
}
我已经检查了断点，并且通过 initwithDelegate 和 AddNotesPopUp.m 中的显示方法成功执行，但是没有出现弹出窗口，我在这里缺少什么？我已经在我的视图控制器中添加了 AddNotesPopUp 的代表和类，我也没有收到任何错误。我正在使用 Xcode 4.6。有什么建议么？
