我试图将网格NSView向上滑动,从另一行中显示另一行NSView.然后,一旦动画完成,第二个NSView将消失,第一个将立即返回到新数据的原始位置.

它可以在4/5的时间内工作.我得到的唯一错误是当第一个视图没有重置到原始位置时; 它停留在动画结束.

这是基本的想法(我这里没有代码):

[NSAnimationContext runAnimationGroup:^(NSAnimationContext *context){
    [[myView animator] setFrame:newPos];
} completionHandler:^{
    [myView setFrame:originalPos];
}];

我在谷歌上遇到麻烦,因为runAnimationGroup:completionHandler狮子座是新手.

从OS X 10.7和iOS 5.0开始,NSFileHandle有两个新属性:readabilityHandler和writeabilityHandler.我试过使用writeabilityHandler,但没有运气.文档很奇怪,它看起来像是readabilityHandler的复制粘贴描述,并用write替换了单词read.

根据文档分配块最终应该调用块.它不是.

- (void)sendResponse:(NSData*)dataToSend
{
    _incomingHandle.writeabilityHandler = 
    ^(NSFileHandle* fileHandle)
    {
        [fileHandle writeData:dataToSend]; // exception is thrown here
        fileHandle.writeabilityHandler = nil;
    };
    // Above block is not called without this line:
    //[_incomingHandle writeData:dataToSend];
}

只有当我尝试同步写入句柄时才会调用它,这是[_incomingHandle writeData:dataToSend]没有意义的.调用它之后会抛出异常:EXC_BAD_INSTRUCTION

*** Terminating app due to uncaught exception 'NSFileHandleOperationException', reason:
'*** -[NSConcreteFileHandle writeData:]: Resource temporarily unavailable'

我也尝试逐个发送数据.没运气.

有没有人成功使用过这家酒店？

根据Apple文档,在回调中FSEvents,

/* These flags are only set if you specified the FileEvents */
/*   flags when creating the stream. */
kFSEventStreamEventFlagItemCreated = 0x00000100, 
kFSEventStreamEventFlagItemRemoved = 0x00000200, 
kFSEventStreamEventFlagItemInodeMetaMod = 0x00000400, 
kFSEventStreamEventFlagItemRenamed = 0x00000800, 
kFSEventStreamEventFlagItemModified = 0x00001000, 
kFSEventStreamEventFlagItemFinderInfoMod = 0x00002000, 
kFSEventStreamEventFlagItemChangeOwner = 0x00004000, 
kFSEventStreamEventFlagItemXattrMod = 0x00008000, 
kFSEventStreamEventFlagItemIsFile = 0x00010000, 
kFSEventStreamEventFlagItemIsDir = 0x00020000, 
kFSEventStreamEventFlagItemIsSymlink = 0x00040000 

但是,我三次检查kFSEventStreamCreateFlagFileEvents调用时没有设置标志

FSEventStreamRef FSEventStreamCreate( 
    CFAllocatorRef allocator, 
    FSEventStreamCallback callback, 
    FSEventStreamContext *context, 
    CFArrayRef pathsToWatch, 
    FSEventStreamEventId sinceWhen, 
    CFTimeInterval latency, 
    FSEventStreamCreateFlags flags);  

但无论我做什么,kFSEventStreamEventFlagItem*当事件从FSEvents …

我是从Snow Leopard工作到家里的Lion装置.我不记得必须:

sudo easy_install pip

狮子座需要吗？在我这样做之前我遇到了错误,并且pip结束了:

[ some@computer ] ~ $ which pip
/usr/local/bin//pip

这是否意味着我将不得不sudo pip安装其他软件包？例如:

sudo pip install virtualenv
sudo pip install virtualenvwrapper

我还应该注意到,我正在使用命令行工具的新单独安装来运行XCode 4.3.所以我的OS X Lion卷上没有/ Developer路径.

我在OSX Lion上,我安装了libxml2(默认情况下),我安装了python(默认情况下)但是它们没有相互通信.在Lion上使用这个最简单的方法是什么？

$ python -c "import libxml2"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named libxml2

试过各种途径,但没有运气.我正在使用10.7.4的MBP.我不记得上次我在Mac上用Python安装任何东西时遇到这么多问题.请帮我在我的本地机器上使用lxml,而不是依靠SVN提交,在Linux机器上远程运行更新.

我正在尝试在Mountain Lion上编译Omnet ++ 4.1.当我输入:

./configure 

我收到以下错误:

configure:error:无法构建Tcl/Tk应用程序,可能是由于配置错误或缺少X11头文件或库.检查config.log以获取更多信息!

我记得在没有任何问题的情况下在Lion上编译它,任何想法如何让它在Mountain Lion上运行？

我正在尝试在本地构建我的应用程序并收到以下错误:

这似乎是我在Linux或Windows机器上看不到的问题.我的环境设置JAVA_HOME来自/ usr/libexec/java_home.这是在我的.bashrc文件中:

export JAVA_HOME=$(/usr/libexec/java_home -version 1.7)

这导致:

~/dev/Endeavor/endeavor-sdk$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home

但是,当我在我的项目上运行Maven时,我从native2ascii插件中收到错误:

[ERROR] Failed to execute goal org.codehaus.mojo:native2ascii-maven-plugin:1.0-alpha-2-SNAPSHOT:native2ascii (default) on project dataAccessServices: Error starting Sun's native2ascii: -> [Help 1]

我的调查指出我使用的是JRE而不是JDK.这很奇怪,因为我清楚地指向JAVA_HOME变量中的JDK .但是,这是mvn -version的输出:

~/dev/Endeavor/endeavor-sdk$ mvn -version
