我使用标准架构（64 位 Intel）（x86_64）、SDK：最新的 OSX（OSX 10.9）和部署目标：10.8 使用 Xcode 5.1.1 构建了应用程序。
打开 NSSavePanel 后，一旦用户单击文件夹，应用程序就会崩溃。以下是代码片段和崩溃日志。这个问题在我的开发 macbook（操作系统：10.9.5）中没有发生。它只发生在客户端的macbook（操作系统：10.8.2）中。顺便说一句，我无法在客户的 macbook 中运行 Xcode。
-(IBAction)onSaveScriptFileAs:(id)sender
{
NSSavePanel *theSavePanel = [NSSavePanel savePanel];
[theSavePanel setTitle:@"Save Test Script As"];
[theSavePanel setAllowedFileTypes:[NSArray arrayWithObject:@"ts"]];
if (tempScriptFileName != nil) {
[theSavePanel setNameFieldStringValue:tempScriptFileName];
}
if ([theSavePanel runModal] == NSFileHandlingPanelOKButton)
{
[self saveScriptFile:[[theSavePanel URL] path]];
[self setTempScriptFileName:nil];
}
}
