我有一个像这样的 CFUserNotificationDisplayAlert 设置:

CFOptionFlags cfRes;

            CFUserNotificationDisplayAlert(5, kCFUserNotificationNoteAlertLevel,
                                           NULL, NULL, NULL,
                                           CFSTR("Okay"),
                                           CFSTR("Stop!"),
                                           &cfRes);

            switch (cfRes)
            {
                case kCFUserNotificationDefaultResponse:
                    strTest = CFSTR("Default response");
                    break;
                case kCFUserNotificationAlternateResponse:
                    strTest = CFSTR("Alternate response");
                    break;
            }

使用此代码我收到此错误: 使用未声明的标识符 kCFUserNotifactationDefualtResponce (以及其他 kCF*)
有任何想法吗？我有以下进口:

#import <CoreFoundation/CoreFoundation.h>
#import <CoreData/CoreData.h>
#import <UIKit/UIKit.h>

最佳答案

The CFUserNotification API is not available on iOS. Looks to me like you copied that bit of code from a Mac App.
