iPhone崩溃可能与NSUserDefaults有关

时间：2014-11-12 13:04:53

标签： xcode cocoa-touch crash nsuserdefaults

新信息：我已在手机连接到计算机时复制了崩溃，并启用了异常断点，此时应用程序暂停。如果有人想在我停止应用程序之前帮助我获取相关信息，那将会很棒。它阻止了我在一条线上创造了一个我几周来一直没有问题的声音，这令人困惑。

我最近在我的游戏中实施了NSUserDefaults，并且它已经导致崩溃。问题是，当它连接到我的计算机时它永远不会崩溃所以我无法抓住崩溃 - 我只是假设它与NSUserDefaults有关。

截至目前，我只在我的NSUserDefaults中存储了Ints。我今天早上意识到我还没有使用synchronize电话，这会导致崩溃吗？

另外，如何检查不存在的密钥？

当我点击从游戏菜单切换到实际玩游戏时发生崩溃。游戏场景initWithSize中的第一行代码之一是调用检查和NSLog一些默认值。

新信息：查看崩溃日志后，此崩溃似乎有两个部分。首先，KERN_PROTECTION_FAILURE在我使用它时崩溃应用程序，实际上另一个＆＃34;崩溃＆＃34;几分钟后报告，有时我确定我不使用该应用程序。

检查NSUserDefault对象是否为null执行此操作：

NSUserDefaults *example = [NSUserDefaults standardUserDefaults];

NSObject * object = [example objectForKey:@"test"];

if(object == nil)
{
    //object is nil
}
else
{
   //object isn't nil
}

然后你需要在NSUserDefault

内做一些事情 
[example synchronize];
