问题 I am trying to use the new Auto Layout in Lion because it seems quite nice. But I can not find good information about how to do things. For example: I have two labels: +----------------+ | +------------+ | | + label 1 | | | +------------+ | | | | +------------+ | | | label 2 | | | +------------+ | +----------------+ but the first label gets not always populated with content, sometimes there ist just no content for it. What I would like to do is to automatically show the label 2 where label 1

问题 Failed system call was shmget(key=5432001, size=16498688, 03600). HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter. You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 16498688 bytes), reduce PostgreSQL's shared_buffers parameter (currently 1536) and/or its max_connections parameter (currently 104). If the request size is already small, it's

问题 Every time after I call glClear(GL_COLOR_BUFFER_BIT); , I get the OpenGL error "invalid framebuffer operation". The call seems to work just fine, and nothing seems wrong. I call glClear(GL_COLOR_BUFFER_BIT); first thing in the ::paintGL() method. Huh? Should I just disregard this error? 回答1: My best guess is that your framebuffer is not complete and calling glClear on an incomplete framebuffer is throwing the error. Check the status of the framebuffer using glCheckFramebufferStatus and make

问题 Im a new Java developer and was thinking about getting a Mac. But I heard that OSX Lion does not support Java. Does that mean that I cannot develop Java on a Mac? Or that I just have to go get all the Java downloads myself? 回答1: What it means for right now, is nothing has changed, except that the JDK 6 and on is now a separate download via Software Update. For JDK 7 it will be available from Oracle, maybe even through the App Store if we are lucky! What has happened is Apple has quit mangling

问题 On my old Mac running Snow Leopard, I could type "ios" into spotlight and it would start up the iPhone/iPad emulator by itself. I have since had to get a new machine running Lion. I have installed Xcode for Lion, I have installed the developer tool options from the preferences panel. But the "ios" option is no longer there :( The only way now seems to be to run Xcode, create an empty project and then launch emulator with the run option. I have searched and searched the intertubes and the
