Question

我正在尝试使用我自己的简单绑定PushManager在robovm.0.0.14上注册推送通知，如下所示：

#import "PushManager.h"

@implementation PushManager

-(void) registerForPushNotifications
{

    NSLog(@"Registering for push notifications");
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        NSLog(@"Registering for IOS 8 and later");
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

}

@end

它正在使用IOS8设备，但应用程序在类链接阶段崩溃在IOS 7设备上，如下所示：

dyld：未找到符号：_OBJC_CLASS _ $ _ UIUserNotificationSettings
参考自： /var/mobile/Applications/6C45E5E5-AF8F-43E8-9680-5CD3076DB1FF/Game.app/Game 预计在：/System/Library/Frameworks/UIKit.framework/UIKit中 /var/mobile/Applications/6C45E5E5-AF8F-43E8-9680-5CD3076DB1FF/Game.app/Game

我知道{8}会出现UIUserNotificationSettings类，但是如何在iOS 7上忽略绑定的PushManager类？

是否有针对此iOS版本特定问题的解决方法或修复方法？

我检查了相关的类UIUserNotificationSettings是否存在，并且仅适用于iOS 8。

NSClassFromString(@"UIUserNotificationSettings")

这有些间接，但对我有用。
