  • Having a UITextField in a UITableViewCell

    - by Mathieu
    Hi! I'm trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I'm still unable to have a fully working UITextField in some of my UITableViewCells, just like in this example: http://img231.imageshack.us/img231/4858/picture4za3.png Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven't been able to correctly implement the keyboard events. I tried with a bunch of examples from Apple (mainly UICatalog, where there is a kinda similar control) but it's still not working correctly. Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a UITextField in a UITableViewCell, that works fine? Thank you very much.

  • Detailstext in TableView from Coredata Iphone

    - by user554867
    Hey, that is my first question here at stackoverflow. Let me try to be specific as I can. The project is as follows: I am trying to parse an xml file in an iphone app, which works already. I am saving the parsed data into the CoreData of the Iphone. So far so good: I have two elements of the xml file which I want to show in the tableview as the text and the detailtext. Now the strange behaviour occurs: If I take the data of the Core Data and trying to visualize them in the tableview, then both elements are displayed in seperate cells and not as detailtext of the element. If I am just taking a constant string for the detailtext, then it works, but if I am trying to take for every cell a specific element from the Core Data then it is shown seperately in the tableview. I googled a lot, reading here and there. I dont know which code I should show because I dont have a clue where exactly the mistake could be. Maybe someone can answer that immediately because it is a stupid mistake somewhere, which is common. Thanks for your help.

  • Best way to create Default.png image for iPhone app

    - by Alex
    Originally I though I'll just take a screenshot of my app on the iPhone then tweak it in Photoshop. The images should be 480 x 320 according to Apple doc, and the dimensions of my screenshot are 480 x 320. But, the screenshot contains notification area (where reception bars, battery life, etc. are displayed) So, if I chop that part off my image will be a bit shorter and not 480px high. What do I do? Submit a shorter image? Stretch it up so it's 480px but without the notification bar? Submit it with the notification bar in the image? How did you create your Default.png?

  • How to format date from string?

    - by 4thSpace
    I have a string with this value: 2010-05-13 23:17:29 I'd like to format it and am using the following code: NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateStyle = NSDateFormatterMediumStyle; NSDate *formattedDate = [formatter dateFromString:dateString]; [formatter release]; When the debugger reaches the release line, formattedDate shows "invalid CFStringRef" and Cannot access memory at address 0x0 Any ideas what I'm doing wrong?

  • UIImagePickerController Crash after 5 to 7 pictures - again

    - by Sophtware
    OK, I know this one has been beaten to death on this forum, but I'm still having the memory problem and I have tried all the techniques on the web to get around this. I have an application that uses the UIImagePickerController to capture an image from the camera. I've tried both creating and destroying the controller for each picture, and keeping it around for the life of the app. Both are failing. The first way crashes the phone almost immediately. While the second, leaving the controller around, crashes the app after about 5 to 7 pictures. My original app used an undocumented API to get around this issue, but Apple rejected it because of this. I really need to get my app to the store. Does anyone have code showing how they got around the issue? I know there is a way because there are apps on the store using the camera, but I just can't seem to get it. Any help is greatly appreciated! I can post my code here too, if needed.
