沙箱应用程式& NSOpenPanel导致崩溃 [英] Sandboxed app & NSOpenPanel causes crashes

问题描述

我在我的Cocoa应用程序中做一个简单的文件打开面板。我启用权利和应用程式沙箱。
但是在OS X 10.9，当应用程序使用 NSOpenPanel 打开一个对话框时，会崩溃：

< blockquote>

应用程序特定信息：

由于未捕获异常NSObjectNotAvailableException而终止应用程序，原因：service com.apple.appkit.xpc.openAndSavePanelService无法初始化NSOpenPanelService的实例代表{

资料来源：

 code> self.panel = [NSOpenPanel openPanel]; 
 panel.delegate = self; 
 panel.canChooseDirectories = YES; 
 panel.canChooseFiles = NO; 
 panel.canCreateDirectories = YES; 
 panel.allowsMultipleSelection = NO; 
 [self.panel beginSheetModalForWindow：contextWindow completionHandler：^（NSInteger returnCode）{
 ... 
}];有没有人看过这个？

确实，您必须专门允许对用户选择的文件的读/写权限。在Xcode 5.1中，它位于Capabilities  -  App Sandbox下。
 
 
 
  
 
I am doing a simple file open panel in my Cocoa app. I enable entitlements and app sandboxing.
But on OS X 10.9, when the app should open a dialog using NSOpenPanel, it crashes with:

Source:
self.panel = [NSOpenPanel openPanel];
panel.delegate = self;

Has anyone seen this before?
解决方案
Indeed, you have to specifically allow Read/Write permissions on User Selected Files. In Xcode 5.1 this is under Capabilities - App Sandbox.
