I'm actually enjoying it so much I'd love to extend this to my controller layer, particularly my UIViewController subclasses. Unfortunately, many UIKit classes don't function...
I have added a UISlider control to an iPhone View-based application and have wired up a text field that gets the values from the slider. To fit with the user interface colors in the application I need to change the color of the slider. With a little googling I was able to find 2 samples which do this (http://blog.hill-it.be/post/2009/03...
I'm trying to overlay a custom semi-transparent image over a base image. The overlay image is stretchable and created like this: [[UIImage imageNamed:@"overlay.png"] stretchableImageWithLeftCapWidth:5.0 topCapHeight:5.0] Then I pass that off to a method that overlays it onto the background image for a button: - (void)overlayImage:(U...
My colleague and I have been struggling with unit tests now for weeks. We have tried to get SenTest, GTM, and other frameworks set up, but we can never get past a gnarly ball of linking errors. Here's where I am now with GTM. I would appreciate any guidance. Beyond helping out on SO, if you have experience with this, I'd happily pay a ...

I am trying to pass through touches from a custom UIView to a UITableView underneath (the UIView is directly on top of the UITableView). However, it does not seem to be working. In my custom UIView, I have tried all of the following (I'm using touchesMoved as an example but I've implemented this for all 4 touch methods) - (void)touche...
Hi, I would like to know what would be the most elegant approach to extract digits from a double in ObjectiveC using Cocoa Touch (this needs to run on an iPhone): Let's suppose you have a double : 1.423 How would you get each "1", "4", "2", "3", that compose the double in several variables ? In the end I would like to get something...

My application creates CSV files, stored in the documents directory, with the purpose of being later imported into Microsoft Excel. What is the best way to transfer these files in an end-user-friendly way, via the iPhone USB cable, to a MacBook? If there is some way to do this exclusively with code on the phone itself (doubtful) that w...
I have a UITableView where a cell needs to be filled in with a date by selecting it through a pickerview. Instead of pushing the pickerview onto the navigationController I would want to let it slide up halfway into the screen with the tableview still visible in the upper half of the screen. I've seen some apps doing this neat effect befo...

I initially load data into two entities (representing 'speakers' and 'titles') I then load a third entity for 'sessions' and try to set relationships to 'speakers' and 'titles'. (from session to speaker and title is one-to-one. from speaker/title back...

What I mean is, do animators work on an animation in say Flash (or some other kind of key frame animation program) and then export it to the iphone somehow? For example, say I am an animator and I want to create a person waving for an iphone game. What type of external program would I use and then what libraries on the iphone sdk would...

I am currently trying to convert a touch from screenspace, to where it is in worldspace for a 2D game I am working on. The view I am working on has nearly the same coordinate system as the screen, basically if someone touches the x = 345, y = 500 pixel on the screen, it will be the same on the view, although the y will be backwards beca...
