I have a view hierarchy as a subview of a UIScrollView instance. The view hierarchy uses a simple container view as a wrapper around a horizontal row of subview tiles each of which is a UIView subclass that overrides drawRect. Nothing fancy. As a sanity check I echo the bounds, frame, and transform of each subview tile. To my astonishme...
I have tried Instruments and Shark to profile an iPhone app, but both use a data sampling approach, by regularly taking screenshots of thread stacks. I would prefer to have a full coverage profiling tool, which would record every single function call and the time spent in functions and their subroutines. This seems intuitively better th...

On top of this are 8 buttons in various places along the view/image, when one of the buttons is selected i update 'xPoint' and call the below to updat...
Hey guys, My app needs to have variable height table cells (as in each table cell differs in height, not that each cell needs to be able to resize itself). I have a solution that currently works, but it's kludgy and slow. My Current Solution: Before the table cells are rendered, I calculate how high each cell needs to be by calling s...
Hi, I need to ensure that my app gets the correct time, not the time set by the user in settings. So for instance, once the user starts the app, I'd want to get a timestamp. The user would see the elapsed time on a timer on screen updated every second. When the user exits the app, and after some time restarts the app , the timer wou...

Hi, I'd like to detect from within my app whether the iPhone has been rebooted since last time my app was started. I need to do this because my app uses the timer since last system reboot to clock a user's time and I want to detect reboot so I can invalidate the time. Is there anywhere I could extract the information from the system c...
This question is inevitably subjective, but I will ask anyway. I'm a PC. I've always been a PC. I have very little Apple expertise, although I'm completely happy in *nix. I've plenty of experience with development, and consider that I am able to pick up new languages and concepts faster than most of my colleagues (although ML/F# still h...
Does anybody know what might be causing this problem? When I run the code, the program immediately crashes on the simulator before getting anywhere; however if I just go to the simulator and run the program, the changes were loaded and there doesn't seem to be any obvious problems. Or how could I try to pinpoint this problem? [Session ...

Hi, I'm looking for a reliable way to get the time. It can't be tampered with and it needs to work offline. So no internet time , no user time setup in settings and no BSD uptime time since last reboot. I was wondering since GPS works using atomic clock, whether I could access that information. Thank you ...
Most of the times when Iphone program crash, compiler show stack with full of no's, but these no's don't make any sense to me. Very rarely it point out where the problem might be and mostly there are these useless no's. How you can make sure that when your program crashes while development/testing, it shows at what place this cause this ...
I know that happens with commercial websites so I was wondering if commercial iPhone apps that use the MapKit (especially those that generate a lot of traffic) need to get any sort of license from Google Maps as well. My best guess would be no, but just asking in case someone knows better. Also, I would guess Google gets license fees fr...

I am considering using MonoTouch for some iPhone development, but payload size is an important factor. For a user who has never installed Mono on their iPhone before, what would the size of an Objective-C "Hello World" app be compared to a MonoTouch "Hello World" app? More specifically, what is the approx. number of bytes that need to ...
