Question

我使用标准架构（64位英特尔）（x86_64），SDK：最新OSX（OSX 10.9）构建应用程序，使用Xcode 5.1.1构建目标：10.8。

打开NSSavePanel后，一旦用户单击文件夹，应用程序就会崩溃。以下是代码段和崩溃日志。我的开发macbook（操作系统：10.9.5）中不会发生此问题。它只发生在客户端的macbook中（操作系统：10.8.2）。顺便说一句，我无法在客户端的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];
    }
}

崩溃日志：

Answer 1

我唯一的猜测是你使用的是最新的SDK 10.9，而客户端是在10.8上运行的。尝试使用10.8 SDK进行链接并将其提供给客户端。

顺便说一下，我使用的是Xcode 6，但我仍然使用一些技巧链接到10.6 SDK。必须支持老客户。
