远程化类型的iOS8检查权限
远程化类型的iOS8检查权限
提问于 2014-08-29 14:08:21
在iOS8之前，我可以检查用户是否获得通知(警报)权限，比如：
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert)
{
//user granted
}它没有在iOS8上工作，它说：
iOS (3.0 and later) Deprecated:Register for user notification settings using the registerUserNotificationSettings: method instead.控制台说：
enabledRemoteNotificationTypes is not supported in iOS 8.0 and later.那么如何在iOS 8上检查呢？

好吧，我这样解决了我的问题：
BOOL isgranted = false;
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
if ([[UIApplication sharedApplication] respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
isgranted = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
}
#else
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert)
{
isgranted = true;
}
#endifStack Overflow用户

为了更有活力，我扩展了伍哈斯的回答。
- (BOOL)pushNotificationsEnabled
{
BOOL isgranted = false;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0){
if ([[UIApplication sharedApplication] respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
isgranted = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
}else{
}
}else{
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert)
{
isgranted = true;
}else{
}
}
return isgranted;

我在使用isRegisteredForNotifications时运气不佳。最后，我转而使用了currentUserNotificationSettings。
+ (BOOL)notificationServicesEnabled {
BOOL isEnabled = NO;
if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]){
UIUserNotificationSettings *notificationSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];
if (!notificationSettings || (notificationSettings.types == UIUserNotificationTypeNone)) {
isEnabled = NO;
} else {
isEnabled = YES;
}
} else {
UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert) {
isEnabled = YES;
} else{
isEnabled = NO;
}
}
return isEnabled;
