使用arc不允许'unsigned long'UIUserNotificationSettings *'的隐式转换 [英] implicit conversion of 'unsigned long 'UIUserNotificationSettings *' is disallowed with arc

问题描述

iOS 8中的推送通知无效。

Push notification in iOS 8 Doesn't work.

错误显示：

implicit conversion of 'unsigned long 'UIUserNotificationSettings *' is disallowed with arc

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [application registerUserNotificationSettings:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)];
    return YES;
}

我使用ios 8.0和xcode 6测试版。

I'm using ios 8.0 and xcode 6 beta.

推荐答案

• 使用本地或推送通知的应用程序必须显式注册类型的警报，它们通过使用UIUserNotificationSettings对象显示给用户。此注册过程与注册远程通知的过程是分开的，用户必须授予通过请求的选项传递通知的权限。


• 本地和推送通知可以包含自定义操作作为警报的一部分。自定义操作在警报中显示为按钮。点击时，系统会通知您的应用程序，并要求您执行相应的操作。

/// First register notification setting with settings type like 
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications]; // you can also set here for local notification.
