I've found a bunch of iPhone objects inside interface builder, but I assumed there would be a standard pack of icons, gradients etc to make things more applelike. How should I create these graphics, simply using pngs or are there special drawing tools shapes I can use inside interface builder? ...

I have been unable to find a way to anti-alias my rendering on iPhone OS 3.0 + OpenGL ES 2.0. I had assumed there would be multisampling but that appears to not be the case. I've been told that fragment shaders can be made aware of the projected pixel via a partial derivatives extention but I have no idea where that functionality lives o...
What I'm looking for is basically a breakdown of the iPhone OS install base by version number. Ars Technica did it a while ago, but I'm looking for a more recent, or ideally, a regularly updated source of this kind of information. I need this to inform my decision on target platform for my app in order to make the trade-off between the...
The application I am working on manipulates an image for a user, and after the user is done, they can save that photo. I have no problem capturing the screen and saving it (as I want some of the labels saved with the image) but this call: UIImageWriteToSavedPhotosAlbum([self getScreenAsImage] , nil, nil, nil); only appears to allow me...

While writing the touchesBegan handler for my view I ran into this interesting error. Code: ... UITouch *touch = [touches anyObject]; CGPoint point = [touch locationInView:self]; ... The problem is point.x is always zero, no matter where I "touch" and y is a huge number that flunctuates somewhere between 1070000000 and 1090000000. T...
I am creating an iPhone app where the user can send their work in an e-mail to whomever they wish. It is easy enough to open the Mail App using the openURL method of UIApplication. NSString* lsMailToStr = @"mailto:?subject=Subject!&body=Body"; [[UIApplication sharedApplication] openURL: [NSURL URLWithString:lsMailtoStr]]; However, it...
Hi Team, Had a question related to best practices in iPhone login authentication using asynchronous NSURLConnection. Since the same delegate is used for logging into a server, how do folks differentiate notifications coming back for an authentication request, versus when you recieve data for subsequent data requests? Thanks, Sj ...
Hello, I am creating an application for the iPhone which involves having more than one button which all animate the same UIImageView. It works well in the simulator, (like practically all apps) but when it comes to the device it plays the animation well, but with repetitive pressing of the buttons the app quits. So far I have implemented...
I have a web site with an API which publishes the information using JSON. I can access this API fine, but I would really like to store the information in an iPhone application using Core Data. Is there a way to hook the Persistent Store to the JSON API so rather than having to keep them in sync using some algorithm I can just use the w...
Hello, If you have a plain (not grouped) UITableView with a single row, the rest of the screen is filled with blank or empty cells. How do you change the appearance of these blank cells? Af first, I thought they would have the appearance of the cell used in the table view but it seems they don't. The people from Cultured Code (Things) ...
In 3.0 they have Auto-Fill for Safari. You go into the settings app to turn it on, and it needs to tie into an entry in the Address Book. I went into the Settings app to set up mine, and I noticed that it already had guessed who I was. Was it doing this using something in the API? If so, how do I access this function? My iPhone syncs ...
