问题 I'm using Xcode 4.0 and when building my view in Interface Builder everything looks great. When I run my app with the simulator or iOS device the whole view is off vertically (showing a white bar at bottom). It looks to be off by 20 pixels. TabBar, Labels, Tableview, Text and background image are all shifted up. Any ides? Thanks 回答1: Are you running fullscreen? I'm guessing that you've set the Status Bar to 'None' which means the size of your view in the Interface Builder is wrong. In your

问题 I am trying to create a simple modal dialog in XCode 4. I have created the xib, created the NSWindowController derived class and made it the class in the File's Owner of the xib.

Why do I have to call showWindow on my NSWindowController twice on 10.5? and in Apple documentation here: http://developer.apple.com/library/mac/

问题 I just installed a software update that I was prompted for, presumable affecting Xcode. Now when I start Xcode, I am presented with a dialog box which states that Xcode must install the Mobile Device Framework before continuing. When I try to do this, after providing my password, it fails with "An unknown error occurred. See the install log for more details." I do not see anything useful in install.log that identifies the problem. I've tried re-installing multiple times and rebooting to no

问题 I am having a lot of trouble debugging a segmentation fault in a C++ project in XCode 4. I only get a segfault when I built with the "LLVM 2.0" compiler option and use -O3 optimization. From what I understand, there are limited debugging options when one is using optimization, but here is the debug output I get after I run in Xcode with gdb turned on: warning: Got an error handling event: "Dwarf Error: Cannot find DIE at 0x3be2 referenced from DIE at 0x11d [in module /Users/imran/Library

问题 I'm coming from the java world, where files/classes should be layed out well structured within packages/folders in my understanding. What is the best practice in Xcode4? I couldn't find an Apple guideline for this yet. If anyone can push me to the right document, I'd be happy. In case there is no document: what is the best to do so?
