Xcode's help system includes documentation for all the Cocoa and Carbon APIs. However, it would be nice to also have documentation for the standard C and C++ libraries, POSIX APIs, BSD system calls, etc., integrated into the same system. Are additional Xcode documentation sets available, or is there any way to integrate man pages or ot...

I have an app that allows the user to view, manipulate and manage a collection of Schedule objects. Different parts of the app need access to this data. I've experimented with making the collection a singleton, but I didn't find that very clean. I recently changed to storing the global data in the AppDelegate class and using: MyAppDele...

I'm hitting a road block and I'm wondering if the brilliant collective minds here can help. In ObjC CocoaTouch I'm trying to mock an object that takes struct parameters and returns a struct. OCMock is coughing up a hair-ball so I tried wrapping with a Hamcrest matcher. No die. The function/method I'm testing looks something like this: -...

I'm trying to construct a CABasicAnimation to animate the backgroundColor property of a Core Animation CALayer, but I can't figure out how to properly wrap a CGColorRef value to pass to the animation. For example: CGColorSpaceRef rgbColorspace = CGColorSpaceCreateDeviceRGB(); CGFloat values[4] = {1.0, 0.0, 0.0, 1.0}; CGColorRef red =...
Dear all, I found that after setting the [[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO] at viewDidLoad, then if I want to align an image to the top, I will need to set its position as .y = -20; Is there anyway to make the y coordinate of the "top position" to "0" ? or is it doomed to be -20 after hidding the ...
When I use UIImagePickerController to select a photo, either from the Camera Roll or the Photo Library, the image that gets returned to me in the method 'didFinishPickingImage' does not contain the exif data for latitude and longitude.

I have a 320x480 PNG that I would like to texture map/manipulate on the iPhone but these dimensions are obviously not power of 2. I already tested my texture map manipulation algorithm on a 512x512 PNG that is a black background with a 320x480 image superimposed on it, centered at the origin (lower left corner (0,0)) where the 320x480 a...
I am using InterfaceBuilder to set up my app. I have several views being controlled by a UINavigationController. In IB I set up the views using the simulated metrics to position the elements below the Navigation Bar. I have a background texture that is placed in the window object of the Main.nib so that it is shared throughout the app. ...
So I'm pretty sure i already know the answer to this, but does the SDK include access to the combo box control used in mobile safari? It should be easy enough to build one... but I'm not looking to re-invent the wheel if I don't have to. ...
I have a simple application, based of the "Utility Application" template. It retrieves a password-protected XML file (via NSXMLParser). I want to allow the user to set a username and password in the "FlipsideView", how would I go about this? I have the basics in place, the two UITextField boxes, the value of which gets set to a fixed v...
Hi Is it possible to get the street/area where the user currently is by using the CoreLocation framework? So if I get the user's longitude and latitude position, can I get the address (xx street, yy city, z state) from that position? Thanks. Someone had already posted the question before. Just found out http://stackoverflow.com/questi...
Note: This is the opposite direction to most similar questions! I have an iPhone application which I would like to provide a demo of on the Mac. How hard is it to recompile (or rewrite) iPhone applications into Mac applications, assuming I intend to keep the same screen size, and not worry about making my application look "mac-like"? I...
Hi-- I have a viewController (Planner) that loads two view controllers (InfoEditor and MonthlyPlan) when the application starts. MonthlyPlan is hidden behind InfoEditor (on load). So my question is when I exchange InfoEditor for MonthlyPlan (MonthlyPlan gets brought to the top) how can I have data on the MonthlyPlan view be updated. ...
I'm using the following piece of Objective-C code to format a NSNumber, and it works fine most of the time, but it doesn't quite do what I want when the NSNumber object holds an integer (no fractional part). UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(80.0f, 90.0f, 225.0f, 40.0f)]; label.backgroundColor = [UIColor clearCo...
