ipad - 已付费应用的 IOS13 iPad 设置崩溃

Question

我们在 AppStore 上的应用程序已经运行多年，没有任何问题。然而，自 iOS 13 发布以来，虽然应用程序仍然可以正常运行，但进入

iPad Settings -> MyApp

崩溃和设置应用程序将结束，以前的 iOS 版本没有任何问题。

我从 XCODE Organizer 查看了设备日志，可以在日志中看到以下内容:

我在这个问题上摸不着头脑，该应用程序运行良好，只是设置有这个问题。

我有一个关于如何诊断和修复的计划，希望能尽快解决，但想知道是否有人看过这个？

谢谢

Answer 1

最后，经过几个小时的设置、代码等，我终于修复了它。

方法是:

1)编辑我的APP设置的info.plist文件(作为文本)并将所有部分取出到文本编辑器中，文件几乎变成空白。

2)在iPad上重新编译并运行->停止应用程序->进入设置->点击应用程序，现在没有我的设置它可以正常工作，所以，我认为这一定是什么原因造成的。

3)开始将部分粘贴回 info.plist 文件，直到我终于得到了有问题的部分，如下所示:

    <dict>
        <key>AutocapitalizationType</key>
        <string>None</string>
        <key>AutocorrectionType</key>
        <string>No</string>
        <key>DefaultValue</key>
        <string>8101</string>
        <key>IsSecure</key>
        <string>No</string>
        <key>Key</key>
        <string>Admin_iTaxi Server Port</string>
        <key>KeyboardType</key>
        <string>NumberPad</string>
        <key>Title</key>
        <string>Server Port                </string>
        <key>Type</key>
        <string>PSTextFieldSpecifier</string>
    </dict>

4)看起来非常奇怪和奇怪，......我的意思是上面的 block 可能有什么问题？!......为什么这在最新的iOS13之前适用于所有iOS!？......

5)检查所有拼写，重新排序列表以使其与另一个有效的列表相似，更改键盘类型，其他项目，...开始-停止，检查设置，同样的事情，...仍然崩溃!。 ..

6)最后，我把变量名从“Admin_iTaxi Server Port”改成了“Admin_iTaxi Server XXXPort”，重新编译，果然成功了……嗯……为什么!？……

7)回到启动代码，并注意到我正在使用以下设置变量(如果它们不存在):

if (!IsConfigKeyExist(@"Admin_iTaxi Server Port"))
{
        TempServerPortAdmin = 8102;
        [[NSUserDefaults standardUserDefaults] setInteger:TempServerPortAdmin forKey:@"Admin_iTaxi Server Port"];
}

8)然后我想，info.plist文件有KEYs和TYPEs，都设置为，不记得设置任何或等等，因此。

9)将上面的代码更改为:

if (!IsConfigKeyExist(@"Admin_iTaxi 服务器端口"))
{
临时服务器端口管理员 = 8102；
[[NSUserDefaults standardUserDefaults] setValue:[NSString stringWithFormat:@"%li", TempServerPortAdmin] forKey:@"Admin_iTaxi 服务器端口"];
}

10) 恢复 info.plist 上的原始变量名，开始-停止-检查，... Eureeka，.. 现在可以工作了...

结论:不知何故，Apple 在他们的智慧中决定在将 Integer 读入 String 变量时使设置应用程序崩溃......为什么!？......我不知道，但修复(如上所述)不是将您的设置存储为“整数”并感染仅存储为“字符串”，特别是如果您要在 info.plist 文件中使用这些设置。

这解决了应用程序设置因 EXC_BREAKPOINT (SIGTRAP) 而崩溃的问题

我希望这有帮助。

祝你好运!
