iOS 4.3.3 上的 GKNotificationBanner [英] GKNotificationBanner on iOS 4.3.3
问题描述
我在我的 iOS 4.1+ 应用程序中使用框架 GKAchievementNotification (https://github.com/typeoneerror/GKAchievementNotification).此应用已获得 Apple 批准(在应用商店中),但似乎在 iOS 4.3.3 上崩溃.崩溃日志如下:
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
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x00000001, 0xe7ffdefe
Crashed Thread: 0
Dyld Error Message:
Symbol not found: _OBJC_CLASS_$_GKNotificationBanner
Referenced from: /var/mobile/Applications/08289A0B-7AD3-4E37-B29F-A EDFE97B7ACA/PolarDefense.app/PolarDefense

对于不支持的 iOS 版本(iOS 5.0 之前的版本),该框架似乎没有正确丢弃 GKNotificationBanner.
Seems like the framework is not correctly discarding GKNotificationBanner for iOS versions which it does not support (iOS prior to 5.0).
我假设错误在于以下代码,您认为它有什么问题?
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 在更多地方被引用,但总是被#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 50000 包围
GKNotificationBanner is referensed in a few more places but always surrounded by #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 50000
那它怎么会崩溃呢?(为什么只在发布模式下?)
So how come it crashes? (And why only in release mode?)
部署目标是 4.1.我现在读到只有 4.2 才支持运行时检查类是否存在.这可能是问题吗?
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?
推荐答案
认为这可能与我需要链接到 GameKit 相关.将其改成weak并提交到App Store(第三次).
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).
