I have been hunting down memory leaks for some time in my app. As of right now, as I flip back and forth between two views while watching the memory monitor instrument, the real memory fluctuates between 5 and 6 megs. This is all fine -- as far as I can tell everything is getting released properly when I pop back off a view. However, the...
Basically, I have a client that wants a breadcrumb trail implemented in the navigation bar. I realize Apple doesn't recommend this behavior, but the app I'm building is for internal use only and won't be submitted to the App Store. I need something along the lines of what AirVideo uses in their iPad App. Are there any navigation control...

The data I'm populating that table view from may have items from multiple categories, but the default view for the user will be one in which they are viewing all of the items, and then they have the ability to move backwards to a different table view that wo...
Hello I am crossposting this in the groups.google because I find it so very difficult to get answers on Three20 I can see from other posts that it is hard getting some newbie/starter help on Three20, but it is really hard to get started with Three20 with the lack of documentation and examples, so I will try :) Bear with me, I am just t...
In my application I have a UIViewController that opens a UIImagePickerController using presentModalViewController.

I'd like to try implementing a visual swipe for an iPhone project, like they do in some games, like Fruit Ninja. As you drag your finger around the screen, it leaves a trail that disappears after a while. I would think that you could have a fixed number of points in the "chain" and as new points are added to the front, old ones are rem...
I know this question has been answered a million times over the years... but times, and technologies, change quickly...so looking for "fresh" data ;-) I'm seeking advice on a robust, and relatively straight forward, approach toward moving fairly complex objects from a Rails 3 back-end to an iPhone 3(4) app. There is no pre-existing API ...

For example, all the PNG files I add to the project always wind up in the bundle. Conversely, the .m and .h files are not. How can I control or specify which are or are not included?

It is being called from a [NSURLConnection connectionDidFinishLoading] delegate method. Here is the code. { // Create a new MOC because we are working on...
I know this is quite possibly a lame question, but I've pulled three consecutive all-nighters and I'm very blurry. And I'm new to Objective C and Cocoa Touch. I've created a class that provides a delegate method. I'll use simplified example code since the specifics aren't important. The header file looks like this: #import <Foundation/...
