检查是否启用推送或启用位置 ios sdk

Question

我正在使用以下代码检测这 2 个（推送通知和定位服务）

    [postvars setObject:([CLLocationManager locationServicesEnabled])?@"true":@"false" forKey:@"locationServicesEnabled"];

    BOOL pushEnabled = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
    [postvars setObject:(pushEnabled)?@"true":@"false" forKey:@"pushServicesEnabled"];

但问题是，即使我在应用程序中提示时点击不允许，我也总是对两者都成立。同样在设置应用程序中，我检查了位置设置为从不，通知副标题显示。这段代码有什么问题？谁能在这方面指导我。

Answer 1

仅仅检查 [CLLocationManager locationServicesEnabled] 是不够的。

if([CLLocationManager locationServicesEnabled] && 
   [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
    [postvars setObject:@"true" forKey:@"locationServicesEnabled"];

}

用于通知检查这个很棒

BOOL pushEnabled = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
[postvars setObject:(pushEnabled)?@"true":@"false" forKey:@"pushServicesEnabled"];

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types == UIRemoteNotificationTypeNone) 
   {
    [postvars setObject:@"false" forKey:@"pushServicesEnabled"];
}

检查是否启用推送通知或启用位置服务：

推送通知：

从 iOS 8.0 以上版本开始，即使用户选择退出推送，它也会注册设备并提供令牌。

但是，发送推送时不会向用户显示推送，因此它将 return true.

- (BOOL)isPushNotificationsEnabled {
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]) {
        UIUserNotificationType types = [[[UIApplication sharedApplication] currentUserNotificationSettings] types];
        return (types & UIUserNotificationTypeAlert);
    }
    else {
        UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        return (types & UIRemoteNotificationTypeAlert);
    }
}

enabledRemoteNotificationTypes 自 iOS8.

以来已弃用

要检查 iOS8 中的远程通知状态，您可以使用：

[[UIApplication sharedApplication] isRegisteredForRemoteNotifications];

定位服务：

需要同时检查 locationServicesEnabled 和 authorizationStatus，例如

if([CLLocationManager locationServicesEnabled] && 
   [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
   //Enabled
}
