Hi Everyone:
I am attempting to deploy my first development iPhone app, and am running into some problems. I have successfully went though the online Provisioning Assistant, but now I am stuck. No matter what I do, I always get the following error.
/usr/bin/codesign failed with exit code 1
Anyone have any ideas why this is happening?
Looking to have some alerts/prompts pop up in my iPhone web app but I see the Title is at the top of the alert (I understand this is the normal behavior). My question is can I remove this? or use an alternative solution.
Looking for something that looks like the push notification alert but in JavaScript.
I am working a rss reader app for iphone . What are my options for displaying entry summary in rss feed ( which could be html) in a tableviewcell without compromising scroll performance .
I dont control the feed so html in summary section is out of my control .
I am thinking of uiwebview would be my last option ( so rss feeds have images and stuff in there, unfortunately ) . I was thinking if there was a way to extract summary text from html.
I have a UIImageView and want it to be displayed with a specific blend mode. I know the iPhone has different blend modes, and it's probably possible to do it with a lot of CG code...but maybe there's a nice way with the CALayer of UIImageView?
Hi, Shark has identified a area of code to be improved - Unaligned loop start
and recommends adding -falign-loops=16 (gcc compiler flag). I've added this to
Other C flags in iphone Xcode both to the dependant project and top level project. However it still does not seem to affect the performance and Shark is still reporting the same problem
so it appears it didn't work.
Am i doing this correctly?

I create a .caf audio file using AVAudioRecorder and if I try and play it back using AVAudioPlay I get no sound on the iPhone (if played in simulator works fine). If I close my application and reopen the file plays fine. Also I am not able to adjust the phone volume after recording unless I close and reopen my application. Any ideas?

Hey,

I've tried some code from each of these questions:
How to make one color transparent on a UIImage?

but have come up unsuccessful, unfortunately working with Core Graphics and images is not my strong suit.
How would I go about accessing a UIImage's raw data and changing the white pixels to clear?
Thanks!
So I am using the Three20 library for an iPhone app, and want to use the TTSpeechBubbleShape style for a view. But the triangle doesn't seem to want to draw on the left or right sides. I see in the source that it's a lot of geometry and was wondering if anyone had tackled this or knew how to fix it.
Hi,
Meaning the C10K problem, what is the best way to do asynch I/O on Mac OS X (assume to use on Mac and iPhone/iPad)?
On Linux our choice is epoll, on Windows is I/O Completion Ports.
Top priority is performance and scalability (thousands of connections).
Thanks

I'm trying to create a universal iPhone app, but it uses a class defined only in a newer version of the SDK. The framework exists on older systems, but a class defined in the framework doesn't.
I know I want to use some kind of weak linking, but any documentation I can find talks about runtime checks for function existence - how do I check that a class exists?

Im trying to "get" when a finger/touch leaves a UIButton in objective C for iphone.
I was told in another answer to use UIControlEventTouchDragExit however this event only fires when the touch gets about 100 pixels away from the button, whereas I would like it to be immediate. The apple docs say that goes according to the bounds however my understand is the bounds and the frame are the same unless you rotate the UIbutton (or whatever)
