I'm building a table with some text that is HTML, so I am using a UIWebView as a subview of my custom table cells. I already ran into one problem - as I scrolled down in the table, it would take the UIWebViews a second to update. For example, I'd be viewing Cells at rows numbered 1, 2, and 3. I'd scroll down to say 8, 9, and 10. For a mo...

I'm trying to get multiple levels of hierarchy working with Navigation Controllers. I have 3 levels of hierarchy and I can move down through the levels of hierarchy, but I can only go back one level and not two levels, back to the starting view.

I'm working on my first video game for the Android platform as a bit of a nights and weekends project. It is coming along nicely, but I am very unhappy with the control sensativity. In this game, you move an object left and right on the screen. On the bottom of the screen is a "touchpad" of sorts, which is where your finger should rest...

How would I go about doing something like that ? Basically I want to do something only if the user touches somewhere within a circular area that's not visible. Any help/...
Hi All, Is there any built-in function in Objective-C allows me to deep copy a NSMutableArray? I looked around, some people say [aMutableArray copyWithZone:nil] works as deep copy. But I tried it seems no. Right now I am manually doing the copy one by one (a 9*9 array): //deep copy a 9*9 mutable array to a passed-in reference array ...
I have a date string (well, NSData, but that's easy to convert to a string) that's in what I believe is the format the HTTP standard uses: Mon Apr 17 19:34:46 UTC 2006 Is there any better (i.e. less error-prone) way to parse that than specifying the format string by hand in an NSDateFormatter? (My application is an iPhone app, but I ...

iPhone apps are great for managing or viewing small elements of data however doing mass and/or long data entry or typing is a pain. For apps that need to have longer dynamic data that can be used on the iPhone but more easily created at the desktop, what sort of options exist for getting data from the desktop to the iPhone app? Are web...
I'm trying to create a multiview controller for a game, in which one root view controller releases views before switching to another view. The sub view controllers are, in turn, sub-root view controllers themselves since they contain other view controllers. For instance, my singlePlayerViewController will have a shakeObjectViewControlle...
Hey guys, I have a custom object that simply inherits from NSObject. It has 3 members - two floats and an NSDate. My app is going to have an array with a number of these objects kicking around, and I need to persist it between runs. What is the best way to accomplish this?

In an iPhone app I currently have code for downloading a file from the Web to the iPhone and saving it to disk. The problem is that if the file is large then the memory usage of the app skyrockets and the app crashes. I am sure I am just not doing it the "proper" way. Currently I have the following: mediaData = [[NSData alloc] initWi...

I have just started learning objective-C and the iphone sdk and I have a question that I hope someone can help shed some light on. What is the difference in the following: self.view = someView; and [self.view addSubView: someView]; Say for example, in a simple app, where we have only one controller and one container view (has a fe...
Hi I just picked up Obj-C and quite dislike its manual memory management. I decide to go with its Garbage Collection, by adding objc_startCollectorThread();//garbage collection in my Main() and change the garbage collection value to [-fobjc-gc] So is that all I need? So I can program "freely" like I do in Java/Python..etc? ...
