问题 I have a Cocoa webview, with a web application in it. The web application has a fixed toolbar itself, and with the elastic scrolling, and the toolbar coming below the top, it looks bad. Is there a way to disable the elastic/rubber-band scrolling, or at least keep the toolbar from moving with the rest of the content? I can modify the web app as much as neede. 回答1: Maybe this article would help you. In short: disable overflow on HTML and BODY , add a wrapper with overflow:auto around all the

问题 Important Update Strange bug is fixed (at least for me) in Xcode 4.2! I've a severe problem with Xcode 4.1 Build 4B110 under Mac OS X Lion and running Instruments via Xcode. The problem is that Instrument freezes in partly if I start it via Xcode. So if I start a project in Xcode 4.1 and open "Profile" the Instruments UI appears. The timer starts running, but the instruments app doesn't track anything and the more severe problem: The program seems to be running but does not react on any

问题 I have been trying for months to get numpy installed for Python 3 but despite copious amounts of Googling and even posting to the numpy mailing list I am still no closer to a solution. I have managed to get it installed via MacPorts but unfortunately there doesn't appear to be a port of MatPlotLib for Python 3 which is the main reason I am trying to install numpy...so I am a bit stuck... I keep getting the same error whilst trying to build from the setup.py file. I have included the terminal

问题 I'm sandboxing my app, and trying to allow for import/export of multiple files, using an XML file to refer to them. To allow my app (or another sandboxed app) access to the files listed in the XML, I'm also including a serialized security-scoped bookmark. I'm serializing it as described in this answer, and my unit tests (which are not sandboxed) write and read the XML data without issue. When my app resolves the bookmark, the NSURL returned is nil, as is the NSError reference. Since I don't

问题 I haven't touched python and virtualenv in a while, and I believe I setup my MBP with virtualenv and pip, but have totally forgotten how this stuff works. After installing lion, I'm getting this error when I open up a new terminal window: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named virtualenvwrapper.hook_loader virtualenvwrapper.sh: There was a problem running the initialization hooks.

问题 What is the easiest way to activate PHP and MySQL on Mac OS 10.6 (Snow Leopard), 10.7 (Lion), 10.8 (Mountain Lion)? I'd prefer to use any bundled versions before resorting to downloading from the PHP or MySQL websites. That also rules out MAMP and similar. I'm comfortable at the command line in Terminal. 回答1: Open a good text editor (I'd recommend TextMate, but the free TextWrangler or vi or nano will do too), and open: /etc/apache2/httpd.conf Find the line: "#LoadModule php5_module libexec

问题 I am trying to do a simple maven build with IntelliJ IDEA 10.5.1 on OS X Lion and am getting the following error: Error running my-app [package]: No valid Maven installation found. Either set the home directory in the configuration dialog or set the M2_HOME environment variable on your system. I have set M2_HOME to the following, but I am still having issues.
