After spending three weeks learning Objective-C and Cocoa programming for my work, I've been tasked with researching alternatives to it for iPhone development. I know of two existing alternatives, and one future possibility. C# MonoTouch is a C#.NET implementation with bindings for iPhone specific functionality such as touch screen a...
Actually, almost exactly the same thing. A matrix of small views that would expand out when you click on them. I don't know if it makes more sense to take a snapshot of the view as an image and work with that, or if there is a way to keep the views "live". Thoughts on either approach are welcome! ...

I've noticed that there are two different ways to load nib files: 1) via the UIView's initWithNibName:bundle: method and 2) NSBundle's loadNibNamed:owner:options: method. Can someone explain the differences between these two and when it is more appropriate to use one over the other and in what circumstances? For instance, if I'm loading...
I've come across a strange render bug on iPhone OS 3.0... I have two images. One is a non-transparent PNG that is predominately black with a white gradient fading upward. The second is a transparent PNG with translucent clouds. When I overlay the two using UIImageView, the intersection of the clouds and white gradient triggers a rende...
I've read a lot about NSDecimal, NSNumber, NSNumberDecimal, CFNumber... and it begins to be a kind of jungle to me. Basically, I'm trying to create a simple model class that will handle simple computations, like this one: #import <Foundation/Foundation.h> @interface Test : NSObject { float rate; float amount; int duration...

Hey, I'm messing around with NSNumber for an iPhone app, and seeing what I can do with it. For most of my variables, I simple store them as "int" or "float" or whatnot. However, when I have to pass an object (Such as in a Dictionary) then I need them as an Object. I use NSNUmber. This is how I initialize the object. NSNumber *testN...

As I understand, in Objective-C you can only put Objects into dictionaries. So if I was to create a dictionary, it would have to have all objects. This means I need to put my ints in as NSNumber, right? SOo... NSNumber *testNum = [NSNumber numberWithInt:varMoney]; NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] i...

Every time try to set the value of any variable in my model object, I receive 'Unrecognized selector sent to instance' error, and the app crashes.
