Hey folks, I've got a client<=>server app I'm building for Mac OS X, using Objective-c/Cocoa and xCode. I've created a different project for both the apps I have, and I'm wondering the best way to share classes between them. There are several classes I've made that would be useful to both. This far I've been copying them around, but I f...
Hi, I'm curious to know your tips and tricks using XCode and Subversion. Not necessarily only focused on actions that can be done to a svn repo from xcode itself - but what things have you done to make your life easier when working with a svn managed folder that contains an xcode project? What files did you ignore? Any custom built scrip...
Hi, I have 4 textfields in a screen. Consider all textfields have some text in it. When i focus/ click on any textfield the value previously entered in the textfield disappears. How can I restrict this behavior? Any ideas? Thanks, TF ...
As I'm sure you're aware it's common to include both debug and release builds of libraries in their SDKs. My question is whether there exists a standard way of going about this for a Mac OS X framework in terms of distribution and possibly Xcode integration? One option is to ship a second entirely separate framework, e.g. MyLibrary.fram...
Hey, I am wondering how and whether the UIPickerView can be opened due to the user's pushing of an entry in the app's preference pane. Thank you ! I am speaking about iPhone Development. ...
IBCocoaSimulator crashes when IB cannot find the framework, I assume that happens to you too. I can run IBCocoaSimulator without crash, when I manually copy my framework+ibplugin from the build dir into /Users/username/Library/Frameworks. I'm doing this with Finder, this is not optimal, but works. I have searched for a smarter way and ...
The user can choose whether he wants to use an existing image or take a new one for use as the background. Everything works as far as the FirstViewController is concerned. Sadly the image is no longer set as the background when the SecondViewController is displayed. How do I enable the use of the image as background for the SecondView...
You can view the Java API in tree structure. So you can view all the subclasses of Object. How would I view all the subclasses of UIView or NSObject IPhone Cocoa API? I just found out you can do this: self.tableView.tableHeaderView = searchBar; searchBar is subclass of UIView. I want to add a textField to a tableView. I wonder if ...
As someone new to C and iPhone development, I'm making lots of use of the documentation. The "doc sets" pull down has only "iPhone OS3.1" library selected. However, sometimes when I highlight text in my source - eg "sqrt", right click, and choose "find text in documentation" I get a bunch of "Mac OSX Manual Page" hits, with pages title...
i wonder if its a wise choice to store images with core data into binary property say i have a collection of movies and i want to save the image dvd cover into a property the avg size of a cover is 20/30kb (320x480px) the reason i want to do this is for storage management, once i delete the movie i know the image is also deleted i'm j...
Hi, I've been slowly working my way through the examples in Beginning iPhone Development and there are a few things that I have not been able to figure out, but I'm sure you guys can help me with it. In Eclipse there is a Source->Generate Getters/Setters, can you do something similar to synthesize properties in Xcode I also cannot see...
I am currently using Xcode 3.2.1 for learning the iPhone SDK and was wondering if its possible to use the Clang-LLVM and the static-analyser to aid in debugging my code. Currently I am using the default templates, but swapping the compiler in project>settings gives me errors when compiling for the simulator. Is this possible? gary ...
Hi, I have a working iPhone project that I'm trying to rearrange on different projects in order to reuse code. I opened a new project that contains all my utility classes and referenced them from another project. One of the utilities I use is the JSON framework. The project complies OK but at run-time it throws an exception when I'm tryi...
I've got a UIToolbar in Interface Builder and I've noticed that it's locked to being 44px tall. Ideally I'd like to make this larger. Do Apple allow resizing of this control? and if so, how do I go about it? ...
I created a .xcdatamodel Managed Object Model file in Xcode. I selected that file in Groups & Files. Then I go to File > New... > and nowhere in the iPhone Templates / Cocoa Touch Class templates I see the "Managed Object Class" file template. Does anyone know what can be wrong? ...
1) I have the CoreData.framework imported. In Groups & Files I see it in the Framworks list together with UIKit.framework, Foundation.framework, CoreGraphics.framework. 2) I have this code, which should actually work. Don't know what that error means... #import <UIKit/UIKit.h> #import <CoreLocation/CoreLocation.h> @interface RootViewC...
Hello, I have a project that has to be set to "Objective-C++" for the "compile source as" value (no, "according to file type" will not work in my main project). I am having a problem with a file I got from a framework (specifically OpenFeint) that has compile errors when compiled as "Objective-C++". error: pointer of type 'void *' used...
In Xcode, I'd like to go File -> New Project -> and pick View Based Application. But it doesn't have the "Use core data for storage" (like some of the other projects). So I can't assign a core data to it. I'd like to know if this is an issue, and what's the best route to take for what I'm trying to do? (Which is build a core data based...
Hi, I'm working on an iPhone application and I'd like to use the XFSM libraries (see http://fsmbook.com for info) for interacting with finite-state machines. Anyway, I included the two libraries into my program using "add existing frameworks" but when I compile I get the error: dyld: Library not loaded: libbreadline.dylib Refere...
I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the colo...
