我正在寻找一种方法来确定用户是否有,通过设置,启用或禁用他们的推送通知我的应用程序。
当前回答
iOS8+ (OBJECTIVE C)
#import <UserNotifications/UserNotifications.h>
[[UNUserNotificationCenter currentNotificationCenter]getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
switch (settings.authorizationStatus) {
case UNAuthorizationStatusNotDetermined:{
break;
}
case UNAuthorizationStatusDenied:{
break;
}
case UNAuthorizationStatusAuthorized:{
break;
}
default:
break;
}
}];

这个Swifty解决方案对我来说效果很好(iOS8+),
方法:
func isNotificationEnabled(completion:@escaping (_ enabled:Bool)->()){
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
let status = (settings.authorizationStatus == .authorized)
completion(status)
})
} else {
if let status = UIApplication.shared.currentUserNotificationSettings?.types{
let status = status.rawValue != UIUserNotificationType(rawValue: 0).rawValue
completion(status)
}else{
completion(false)
}
}
}
用法:
isNotificationEnabled { (isEnabled) in
if isEnabled{
print("Push notification enabled")
}else{
print("Push notification not enabled")
}
}

if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
// settings.authorizationStatus == .authorized
})
} else {
return UIApplication.shared.currentUserNotificationSettings?.types.contains(UIUserNotificationType.alert) ?? false
}
RxSwift可观察的iOS10+版本:
import UserNotifications
extension UNUserNotificationCenter {
static var isAuthorized: Observable<Bool> {
return Observable.create { observer in
DispatchQueue.main.async {
current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
if settings.authorizationStatus == .authorized {
observer.onNext(true)
observer.onCompleted()
} else {
current().requestAuthorization(options: [.badge, .alert, .sound]) { (granted, error) in
observer.onNext(granted)
observer.onCompleted()
}
}
})
}
return Disposables.create()
}
}
}
在Xamarin,以上所有的解决方案都不适合我。 这是我用的:
public static bool IsRemoteNotificationsEnabled() {
return UIApplication.SharedApplication.CurrentUserNotificationSettings.Types != UIUserNotificationType.None;
}
当你在设置中更改通知状态后,它也会得到实时更新。
尽管Zac的答案在iOS 7之前是完全正确的,但自从iOS 8到来后,它就发生了变化。因为enabledRemoteNotificationTypes从iOS 8开始就已经弃用了。对于iOS 8和更高版本,你需要使用isregisteredforremotenotifizations。
—>使用enabledRemoteNotificationTypes >使用isregisteredforremotenotifizations。
为了完成这个答案,它可以这样工作……
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
switch (types) {
case UIRemoteNotificationTypeAlert:
case UIRemoteNotificationTypeBadge:
// For enabled code
break;
case UIRemoteNotificationTypeSound:
case UIRemoteNotificationTypeNone:
default:
// For disabled code
break;
}
编辑:这是不对的。因为这些是位智慧的东西,它不会与开关工作,所以我结束使用这个:
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
UIRemoteNotificationType typesset = (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
if((types & typesset) == typesset)
{
CeldaSwitch.chkSwitch.on = true;
}
else
{
CeldaSwitch.chkSwitch.on = false;
}
