    I have a really weird error, and I don't know what is causing this.

  • Accessing Private Frameworks to see what they do...

    - by Moshe
    I am investigating the UIFont thing on iPhone. (You can't easily use custom fonts.) I was wondering if the peeking at the Quarts drawing methods would help. The issue is, i don't know where to look or how to access that information. Where can I find the framework headers? Also, I was wondering where the iPhone stores the Fonts. (Path to them...)

  • Add UITabBar Control!

    - by Taimur Hamza
    hi, I m stuck in a really simple problem. And i m afraid my question might annoy some people. The problem i am facing in short is that i want to add UITabBar Control to my iphone application other than the main screen. Let me explain, I have done everything successfully Added UItabbar control from IB in the main window's xib, added a variable at the back end , associated it by dragging the line. Also added a UIWindow variable and wrote these lines . [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; when i launch the application a blank window appears and tab bar shows on its bottom. But the problem i dont want to add it to a particular window which is inside my app. Its no the first screen of my app. Its actually the 3rd screen of my app. Can anybody help ? thanks Taimur

  • MFMailComposeViewController broke CSS styles in html template

    - by Victor
    I use MFMailComposeViewController to send a message in html format. If my html template contains the css styles: <div class="margin:10 10 10 0"> <a href="domain.name">Go To</a></div> In this case it works good. But if I send: <a href="domain.name">Go&nbsp;To</a> then I see the letter that comes with broken styles as there (3D is not my misprint) <div style=3D"margin:10 10 10 10;"><a href=3D"www.google.com">Go=C2=A0To</a></div> Well as the letter goes broken when I insert in the template symbols from national alphabets. Somebody can tell what the problem and check with yourself?

  • iPhone image distortion

    - by Corey Floyd
    Are there any reasons why the simulator will display UIImageViews properly, but incorrectly on the iPhone? My Process: An image in a PNG file Start a UIGraphicsBeginImageContext() Draw the PNG in a CGrect Draw text in the CGRect Create an UIImage from the context Set the image of a UIImaveView to the UIImage Set the frame of the UIImageView to the size of the PNG Add as a subview Outcome: The image does not display correctly. The rightmost 1-3 pixels of the image is just a vertical white line. This occurs only on the device and not on the simulator. I can fix the problem, but only by increasing the size of the UIImageView. If I increase the size.height of the UIImageView by 1 pixel, it displays the UIImage correctly. Of course, these leaves the iPhone to scale my image before drawing it on screen which is not desirable. Any ideas why this occurs or any fixes for it? (I will post my code if needed)

  • Where specifically do UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum save thei

    - by Chris Markle
    Simple question I think and I'll be trying ot myself to see... When people talk about using UIImageWriteToSavePhotosAlbum or UISaveVideoAtPathToSavedPhotosAlbum is the "saved photos album" the "Camera Roll" or the "Photo Library" (or something else either than these two) that I see in the Photo Albums application? I don't think the doc makes it super-explicit as to which it is...

  • NSFetchedResultsController titleForHeaderInSection with formatted NSDate

    - by Daniel Granger
    In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12/2009 12:32:32 +0100) which look a bit of a mess in a header! So I want to use a date formatter on this to make a nice header like "Apr 17 2010" but I can't do that with the [sectionInfo name] as this is NSString! Any Ideas? Many Thanks

  • Optimizing UITableView

    - by Daniel Granger
    I have a UITableview made up with a custom cell loaded from a nib. This custom cell has 9 UILabel s and thats all. When scrolling the table on my iPhone the tables scrolling motion is slightly jerky, its not as smooth as other tableviews! (On the simulator it scrolls fine but I guess its using the extra power of my mac) Are there any tips to help optimize this or any tableview or methods to help find the bottleneck. Many Thanks

  • Detecting iPhone camera orientation

    - by Stephen Petschulat
    I'm getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll. In the UIImagePickerControllerDelegate callback method, the UIImage.imageOrientation comes up as UIImageOrientationRight no matter how the photo is taken. When reading it off the Camera Roll, a landscape shot (turned left) comes up UIImageOrientationUp while a portrait shot comes up UIImageOrientationRight. How can I reliably get the camera orientation in both situations?

  • Are primitive types garbage collected in Android?

    - by snctln
    I know this may be a dumb question, but my background is more in c++ and managing my own memory. I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String and Rect for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense) Anyways I was working though it some more tonight and I realized that I may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection? So a year ago every few seconds I would see a message in logcat like GC freed 4010 objects / 484064 bytes in 101ms Now I see that message every 15-90 seconds or so... So to rephrase my question: Are primitive types (int, float, boolean, etc) included when seeing this message?
