Objective c 通知中心（OS X）-变量作为标题

我对通知中心内容中的set变量有问题。这是我的密码

NSUserNotification *notification = [[NSUserNotification alloc] init];
[notification setTitle:@"version of app"];
[notification setInformativeText:@"message"];
// Delay of pop-up notification
[notification setDeliveryDate:[NSDate dateWithTimeInterval:0 sinceDate:[NSDate date]]];
// Sound of notification
//[notification setSoundName:NSUserNotificationDefaultSoundName];
 NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
[center scheduleNotification:notification];

如何将CbundLeversion添加到通知内容？

虽然这与通知中心无关，但您应该使用

CbundLeversion

创建一个字符串

NSString *version  = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];
NSString *title = [NSString stringWithFormat:@"Version %@", version];

然后只需将title变量设置为title：

[notification setTitle:title];
