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 IOS8 设备上运行,但应用程序在 IOS 7 设备上在类链接阶段崩溃,如下所示:
dyld:找不到符号:_OBJC_CLASS_$_UIUserNotificationSettings

我知道UIUserNotificationSettingsiOS 8 即将推出课程,但如何忽略 iOS 7 上的绑定 PushManager 课程?
是否有针对此 iOS 版本特定问题的解决方法或修复?
