Look at Apple's diagram for the server purchase model . In step #9, how can the server know that it is really talking with an iPhone that is entitled to the purchase, and that Eve is not performing a replay with a dishonestly obtained receipt? The receipt may be valid, but that doesn't prove that the sender is the entitled party. Is there any notion of a device certificate on the iPhone that can be used to sign the receipt? Is there any way to bind the receipt to the device, or bind the receipt to both the iTunes account and to the device, so the server can validate? Apple-Provided Vulnerable

Im trying to use Date Formatters (NSDateFormatter), but I keep getting this error: Program received signal: “EXC_BAD_ACCESS”. Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib") This is nothing to do with NSDateFormatter - the message pasted in saying "Data Formatters" is correct. You will get this message in several situations, possibly most commonly when unable to find a linked in shared library at launch time. You may also get it when short of memory while running, in which case

Is there a way to deactivate the decelerating of a UIScrollView? I want to allow the user to scroll the canvas, but I don't want that the canvas continues scrolling after the user lifted the finger. Mark This can be done by utilizing the UIScrollView delegate method scrollViewWillBeginDecelerating to automatically set the content offset to the current screen position. To implement: Assign a delegate to your UIScrollView object if you have not already done so. In your delegate's .m implementation file, add the following lines of code: -(void)scrollViewWillBeginDecelerating:(UIScrollView *

I have used: [UIApplication sharedApplication].idleTimerDisabled = YES; in a number of Apps developed and running under iPhone OS 2.x and never had any problems with it. They were clock apps so needed to run constantly and ignore the iPhone's idle Timer setting. However, trying to achieve the same with a new App running OS 3.0 (and which needs to be deployed under 3.0 as it uses some 3.0 APIs) I've found the idle Timer to be either ignored or inconsistent. My App plays music from the iPod library and when the music is playing it auto-locks regardless of the above setting. But once you unlock

Has anyone seen an implementation of an "accordion" (maybe called "animated outline") view for the iPhone? I found an example project for Cocoa, but before trying a port, I was hoping that someone has invented the wheel already. To make it clear, in a UIView, consider a stack of sections, each containing a header, and then some contents. When the user touches the header (or through some message/event), if the section is already open => close it; if the section is closed => open it and close any other open section. An example in jQuery looks like: http://docs.jquery.com/UI/Accordion In my case,
