Unable to connect to svn repository with XCode 4

阅读更多关于 Unable to connect to svn repository with XCode 4

After installing XCode 4 I went to the Organizer window to try to verify that the svn repositories that were set up in XCode 3 were recognized. The repositories were there but whenever I clicked on one I would always get the 'busy-wait' spinner. Thinking that XCode 4 didn't properly import the repository information, I went through the steps to re-create one of the repositories from scratch. I'm pretty sure I've input all the details correctly and I know I'm using the right password, but still all I'm seeing is the 'busy-wait' spinner. Beyond this, I don't know anything more about what the

问题 I want to use CHDataStructures as framework: https://github.com/davedelong/CHDataStructures. However there is no binary of the project. So I assume I have to build the .a file myself using xcode. How do I do that in xcode 4? I read the documentation but it is very confusing... Any ideas? 回答1: First we'll grab the CHDataStructures project: git clone https://github.com/davedelong/CHDataStructures.git Next, open the relevant CHDataStructures xcode project open CHDataStructures-iOS.xcodeproj I'll

Xcode 4 configure to use less RAM?

阅读更多关于 Xcode 4 configure to use less RAM?

I've been trying to use Xcode 4 on my 1GB Mac Mini. It's not a happy situation. It frequently slows way down, presumably due to memory shortages. Are there any settings I can change so it won't be such a memory hog? Todd Hopkinson Another post here suggests that the problem may be having the "predictive compilation turned on in the Xcode preferences." I ended up doing the following. None of them reduced Xcode's memory consumption, but they did reduce the memory needed by other programs, and hence solved my problem -- speed is fine now.

Xcode 4 debugging

阅读更多关于 Xcode 4 debugging

问题 since migrating to Xcode 4 I am totally perplexed by the debug view inasmuch as I am unable to see the values of arrays / dictionaries etc. Under Xcode 3 I could view debug console and see the actual values stored? 回答1: Debugging information now appears in the debug navigator (Cmd-5) and the debug area (Shift-Cmd-Y). You can have these areas show up by default when you run the application (or hit a breakpoint) by toggling the options in the "Behaviors" tab of Xcode's preferences. 回答2: To see

XCode 4 active architecture setting

阅读更多关于 XCode 4 active architecture setting

问题 I've updated the XCode to the latest 4 version (final). My project depends on a 3rd party library that was build for armv6. The problem is that i can not change the "active architecture" as it was in 3.x.x instead I see that during linking the active architecture flag is always passed as armv7. Does anyone know how to set active architecture for the build target (or for scheme) ? Thanks in advance. 回答1: Answering to myself ... Yes and no. You can not change the arc but you can trick the Xcode

阅读更多关于 FSMountServerVolumeSync parameter objective c

I'm just starting Objective C after being pampered with Applescript, and I can't seem to get FSMountServerVolumeSync to work. This is going to seem like a completely beginner question, but how do you pass a parameter from a variable to this action ? Let me explain: I want to take a variable called *username and set it to the username in this action. I would also like to do this to *url and url . Is there any way someone could show me a sample of how to set this up, from an absolute beginner standpoint? I am currently reading through tutorials and etc., but I would like to get this section of

How to rename a project in XCode?

阅读更多关于 How to rename a project in XCode?

问题 There are some pretty horrible instructions out there for renaming projects in XCode. Is there no easy way to do this? 回答1: In Xcode 4 try this: ⌘+1, click the blue node with the project name, wait a second, click again (the name becomes editable). That's it. 回答2: In the menu bar choose Project -> Rename... It'll do all the hard work for you and rename everything that needs renaming apart from the folder that the project is in. 回答3: In XCode 4, select the project name at the top of the

I have just downloaded and compiled curl. In my /usr/include folder I can see folder, 'curl' and I can see that I do, indeed, have '/usr/include/curl/curl.h'. However I cannot talk XCode into looking there when compiling. #import <curl/curl.h> In my target's properties I have included '/usr/include' to 'Header Search Paths'. The build continues to fail stating that it cannot find 'curl/curl.h' Am I not adding my search paths correctly? Thanks Rahul User Header Search Paths - searched for #include "..." and Header Search Paths for #include <...> . when we will provide its its frame work then it
