问题 I already have a joystick programmed (finally) and I was wondering how I would get a 'hero' to move about the screen based on where the joystick is? I am using Cocos2d and any help would be greatly appreciated! 回答1: The simplest way to do this is to subclass CCNode for your player object and then manipulate it as you would any other CCNode . To start with, you can change the player's position struct like so: player.position = ccp( player.position.x + [joystick xValue], player.position.y +

问题 xcode used to have a whole bucket of user scripts and an easy way to add shell scripts to the environment. Here is an example. While the User Scripts are still in the xcode 4 help file, I cannot find any way to access the scripts in xcode 4. Did these disappear? 回答1: This link can be a sort of help to you.

问题 I'm using iOS 6 and Xcode 4.6 and with the Interface Builder I added to my controller a UIScrollView that uses all the available space. In this UIScrollView I added some views (a UIImageView , a UITextView and a UITableView (I disabled the scrolling for the UITextView and the UITableView )). In the : - (void) viewDidLayoutSubviews; method I resized all my views by increasing their height (to fit with their respective content). Then, I set the contentSize of my UIScrollView so that it fits

问题 I'm having an issue with my app that runs fine while running when I run using Xcode or the simulator. Stepping through the debugger isn't any help. I've looked at the crash logs and I can't figure out what the issue is (frankly I don't know how to read them unless one of my objects is explicitly listed). There's not much specific to my application, most of the objects listed are lower level items. Running it via Instruments looking for leaks doesn't turn up anything. It seems to be clean. I

问题 I created a simple data model with a 1-many relationship in XCode 4.1 on Lion. The type of the property generated for this relationship is NSOrderedSet, which fails to compile because the type is unknown. I searched the documentation to learn that this is a new kind of collection classes added for Mac OS 10.7 (Lion), especially useful in managed objects (I'm just getting used to the way Apple works: something as basic as a collection type in the language is bound to an OS release...

问题 By default, XCode is setup to download updates associated with the various documentation and API libraries available to the application. This can be disabled from the XCode preferences screen. However, I'd prefer not to disable the automatic updates but, rather, prompt me to start the updates so that I can potentially dismiss them for download at a later time. My reasoning is because I primarily work through a network connection that gains access to the internet through a 4G wireless hotspot
