GKNotificationBanner在iOS 4.3.3 [英] GKNotificationBanner on iOS 4.3.3

问题描述

我使用的框架GKAchievementNotification（https://github.com/typeoneerror/GKAchievementNotification）在我的iOS 4.1或更高版本的应用程序。这个程序是得到苹果的批准（是应用程序商店），但似乎崩溃在iOS 4.3.3。崩溃日志如下：

  OS版本：iPhone OS 4.3.3（8J3）
报告版本：104异常类型：EXC_BREAKPOINT（SIGTRAP）
异常codeS：00000001，0xe7ffdefe
坠毁主题：0dyld的错误信息：

  dyld的版本：191.3
 

好像框架是不正确丢弃GKNotificationBanner为它不（的iOS 5.0之前）支持的iOS版本。

我假设错误主要表现在以下code，你怎么想错了？

  @implementation GKAchievementHandler（私人）
 - （无效）displayNotification：（GKAchievementNotification *）通知{
 ＃如果__IPHONE_OS_VERSION_MAX_ALLOWED＆GT; = 50000
  如果（[GKNotificationBanner类]）{
    [GKNotificationBanner showBannerWithTitle：notification.title
                                      消息：notification.message
                            completionHandler：^ {
                                [个体经营didHideAchievementNotification：通知]
                            }
     ];
  }其他
 ＃万一
  {
    [_topView addSubview：通知]
    [通知animateIn]
  }
}
@结束
 

GKNotificationBanner是referensed在几个地方，但始终＃如果__IPHONE_OS_VERSION_MAX_ALLOWED> = 50000

那么怎么来的崩溃？ （为什么只在释放模式？）

部署目标为4.1。我现在读的运行时间，如果一类存在于检查4.2仅支持。难道这是问题吗？

解决方案

认为它可能有一个需要链接到的GameKit涉及到了我。将其更改为弱并将其提交给应用程序商店（第三次）。

I am using the framework GKAchievementNotification (https://github.com/typeoneerror/GKAchievementNotification) in my iOS 4.1+ app. This app is approved by Apple (is on app store) but seems to crash on iOS 4.3.3. The crash log is the following:

OS Version:      iPhone OS 4.3.3 (8J3)
Report Version:  104

Seems like the framework is not correctly discarding GKNotificationBanner for iOS versions which it does not support (iOS prior to 5.0).

I am assuming the error lies in the following code, what do you think it wrong?

@implementation GKAchievementHandler(private)
- (void)displayNotification:(GKAchievementNotification *)notification {
 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 50000
  if ([GKNotificationBanner class]) {
    [GKNotificationBanner showBannerWithTitle:notification.title 
                                      message:notification.message
                            completionHandler:^{
                                [self didHideAchievementNotification:notification];
                            }
     ];
  } else
 #endif
  {
    [_topView addSubview:notification];
    [notification animateIn];
  }
}
@end

GKNotificationBanner is referensed in a few more places but always surrounded by #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 50000

So how come it crashes? (And why only in release mode?)

Deployment target is 4.1. I read now that the run-time checking of if a class exist is only supported in 4.2. Could this be the problem?

解决方案

Think it could be related to me having a required linking to GameKit. Will change it to weak and submit it to App Store (for the third time).
