小编Equ*_*000的帖子

我有我的应用程序的以下Info.plist,问题是我用扩展myapp保存的文件似乎没有拿起我从图标集创建的MyApp图标(应用程序正确使用图标)所以猜测有什么东西在plist中错了.

我假设如果我在某些时候运行我的应用程序时工作,我保存的文档会突然显示给定的图标.

如果这很重要,文档将从一组基于NSCoder的类中保存.单击这些文档也会打开我的应用程序并正确加载文件,因此混淆了我所缺少的文件中显示的图标....

我已经创建了一些代码来使用AV Foundation对mov文件进行屏幕捕获,我的下一步是记录Mac播放的声音,以便以后添加到录制的视频中.我做了一些挖掘,看起来我可能需要实现某种音频驱动程序来捕获音频.关于如何实现这一点的任何指针？

我假设以某种方式需要AudioUnit和IOKit ......

提前致谢.

我有一些显示窗口的代码......

- (IBAction)displayWindow:(id)sender
{
    NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 50, 50) styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO];
    [window setBackgroundColor:[NSColor blackColor]];
    [window setAlphaValue:.5];
    [window setLevel:kShadyWindowLevel];
    [window setReleasedWhenClosed:YES];
    [window makeKeyAndOrderFront:self];
    self.window = window;
}

并关闭窗口....

- (IBAction)closeWindow:(id)sender
{
    [self.window close];
}

和窗口被定义为一个强大的属性......

@property (strong) NSWindow *window;

代码第一次工作,但第二次显示窗口时......

self.window = window;

与EXC_BAD_ACCESS崩溃...

我究竟做错了什么？

提前致谢....
