iOS檢測是否開啓定位、是否容許消息通知

iOS 判斷是否開啓定位

+ (BOOL)isLocationServiceOpen {
    if ([ CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {
        return NO;
    } else
        return YES;
}

iOS 判斷是否容許消息通知

+ (BOOL)isMessageNotificationServiceOpen {
    if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) {
        return [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
    } else {
        return UIRemoteNotificationTypeNone != [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
    }
}

iOS 跳轉系統設置打開定位頁面

if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) {
        NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
            [[UIApplication sharedApplication] openURL:url];
        }
    } else {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
    }

iOS 跳轉系統設置打開消息頁面

if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) {
        NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
            [[UIApplication sharedApplication] openURL:url];
        }
    } else {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=NOTIFICATIONS_ID"]];
    }

注：SYSTEM_VERSION_GREATER_THAN 是判斷版本的宏定義

#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
