Hi, I was using an app the other day that crashed, but as it crashed also asked to send an email with the crash info. Does anyone know how this is done? Perhaps it was an exception handler in the code that before it lets the app die, sent the email, but just wondering if there are any onCrash type hooks in the iphone sdk. Thanks, Chr...

Hello, I need a background process to run every minute or so. I do not want this process to interfere with the responsiveness of the rest of the app. Would this be a good candidate for a thread?

I would like to have a main UIView take care of adding one of multiple UIViews as a subview. Since only one subview is active at any time, and the subview completely covers the main view, I might as well replace the main view. But this takes some effort, and I'm not sure if it would be worth the small gain in performance. Am I going to s...
We're working on a couple simple games and we have some performance problems that we keep running into, and I was curious if it was a code issue or a "we're using the wrong objects" issue. Our games are basically simple ones that work as follows: We have a custom view that we load, and a custom object that is our game engine. The view ...

That's an issue I still don't understand. Sometimes I have to write: NSString* myVariable; myVariable = @"Hey!"; Then, for example I define a Structure "DemoStruct" and get an Variable that uses it. Lets say I have a Structure that has x and y vars from type double. I want to pass this var to a method which then manipulates my var, ...
My iPhone app needs to do some URL escape sequence encoding for a form parameter. The NSString stringByAddingPercentEscapesUsingEncoding as stringByAddingPercentEscapesUsingEncoding doesn't escape a lot.

Is it true, that the Asterisk always means "Hey, that is a pointer!" And an Pointer always holds an memory adress? (Yes I know for the exception that a * is used for math operation) For Example: NSString* myString; or SomeClass* thatClass; or (*somePointerToAStruct).myStructComponent = 5; I feel that there is more I need to k...

Hi, I was wondering how the autorelese works on the iPhone. I though that once you send an autorelease to an object it is guaranteed to be retained in till the end of the scope of the block the autorelease was sent. Is that correct? I was initializing a view from a NIB in the applicationDidFinishLaunching like below: (void)applica...

I want to perform the same action over several objects stored in a NSSet. My first attempt was using a fast enumeration: for (id item in mySetOfObjects) [item action]; which works pretty fine. Then I thought of: [mySetOfObjects makeObjectsPerformSelector:@selector(action)]; And now, I don't know what is the best choice. As far...
