跳转设置页面方法

iOS检测是否开启定位、是否允许消息通知

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

iOS 判断是否开启定位

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

iOS 判断是否允许消息通知

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

iOS 跳转系统设置打开定位页面

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 跳转系统设置打开消息页面

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 是判断版本的宏定义

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