我正在尝试使用操作按钮发送本地通知。 通知没问题。但不显示操作按钮。 我正在使用 Xcode 6.3.2 iPhone 6 iOS 8.2
发送通知
UIApplication *myapp = [UIApplication sharedApplication];
UILocalNotification *test = [[UILocalNotification alloc] init];
if(test) {
NSLog(@"Sending notification");
test.alertBody = @"jothi test alert";
test.alertTitle = @"kottapa";
test.soundName = UILocalNotificationDefaultSoundName;
test.alertAction = NSLocalizedString(@"View Details", nil);
test.category = @"MY_CATEGORY";
[myapp presentLocalNotificationNow:test];
}
在应用程序委托(delegate)中didFinishLaunchingWithOptions:
UIMutableUserNotificationAction *myAction =
[[UIMutableUserNotificationAction alloc] init];
myAction.identifier = @"MY_IDENTIFIER";
myAction.title = @"Test Action";
myAction.activationMode = UIUserNotificationActivationModeBackground;
myAction.destructive = NO;
myAction.authenticationRequired = NO;
//------------
// First create the category
UIMutableUserNotificationCategory *inviteCategory =
[[UIMutableUserNotificationCategory alloc] init];
// Identifier to include in your push payload and local notification
inviteCategory.identifier = @"MY_CATEGORY";
// Add the actions to the category and set the action context
[inviteCategory setActions:@[myAction]
forContext:UIUserNotificationActionContextDefault];
// Set the actions to present in a minimal context
[inviteCategory setActions:@[myAction]
forContext:UIUserNotificationActionContextMinimal];
NSSet *categories = [NSSet setWithObject:inviteCategory];
UIUserNotificationSettings *settings =
[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound
categories:categories];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
最佳答案
您的代码有效,您只需向左滑动通知即可看到操作按钮(或者在设备未锁定时将其下拉,如果它以顶部横幅的形式呈现) )。
另外,我猜您已经这样做了,但只是没有包含代码,为了处理用户选择的操作,您需要在应用程序委托(delegate)中实现此方法:
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler
