  • Cocoa Touch best practice for capturing/logging/diagnosing crashes

    - by Dylan
    As I get closer to releasing my first public iPhone app I'm concerned about catching crashes in the field. I'm curious to hear how others have gone about this. I'm not sure what's possible outside of the debugger. Is all lost with an EXC_BAD_ACCESS or can I still catch it and get something useful into a log? Is the program main() the spot to put a @try/@catch?

  • UITableView : detecting click on '-' button in edit mode

    - by synthez84
    Hi all, On my iphone app, I have a UITableView in edit mode, containing custom UITableViewCell. I would like to detect when user has clicked on the left button of each cell (minus circular red button, the one that is animated with a rotation), just before the "Delete" button appears. I would like to be able to change my cell content in that case... Is that possible ? Thanks !

    - by Morgan
    Hey, i was wondering how to set the focus to a textbox in mobile safari. I've tried document.myForm.myTextArea.focus(); which works in regular safari, but it does not seem to work in mobile safari. To clarify, i want to set focus to a text box as soon as the user loads a page, and have the iphone keyboard pop up.

    Hi Anybody know how to programmatically generate audio podcast files with bookmarks that can be used in iTunes / iPod / iPhone / iPod touch? Specifically text bookmarks (bookmarks with titles) that the listener can skip to a specific point in time in the audio file. Also how to add the text transcription of the podcast's content. Even better if you have an example Cocoa code or library to write the audio file. Thanks.

  • Memory Leak from Foundation & CFNetwork Library

    - by Lakshmie
    I am using instruments to resolve memory leak issues for an app in iPhone. I just wanted to know if I have to resolve the leaks coming from Foundation and CFNetwork Libraries. Specifically, the leaks are from: 1. NSCFString 2. NSConcreteData 3. General Block-3584 Since they do not directly point to the code that I have written, how should I resolve them, if I have to? Thanks.

  • iTunes App Store: Does a major version upgrade = longer approval queue time?

    - by erlingormar
    I'm wondering if anyone has insight into this... when releasing an update of an iPhone application, should I expect the approval process to take longer if I submit something that's declared as a major version update (as compared to a minor version)? Last time around (about the time the big Facebook-update was released) our wait time for a minor version review was 21 days (16 working days).

  • UISegmentedControl not expanding size for navigation bar/very squished

    - by davetron5000
    Running through an iPhone SDK book and one of the examples has me creating a table and then later adding a UISegmentedControl to the table for sorting. I dutifully did this in IB, and it looks great: When I run it in the simulator or my phone, it's totally squished: The buttons work perfectly, it's just they are not sizing according to their content. Any ideas what's going wrong? Here's the attributes I have set:

  • Speed of NSScanner vs NSXMLParser?

    - by Chris
    I have an iPhone App that reads in an XML file, then pulls out the necessary data by looping through an NSScanner. The XML is not particularly long. I am wondering if it would be worth the work to implement NSXMLParser in place of using NSScanner, if I will see any real improvement in speed?

  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?
