  • Add UIView behind UITableView in UITableViewController code

    - by Drew C
    I would like to use a fixed image as the background in a simple grouped table view in my iPhone program. Unfortunately, no matter what I do, the background is always solid white. I have followed several supposed solutions on this site and others to no avail. Here is the relavant code in the viewDidLoad method of the table view controller class (note, this code uses a solid blue color rather than an image for simplicity's sake): self.tableView.opaque = NO; self.tableView.backgroundColor = [UIColor clearColor]; UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; backgroundView.backgroundColor = [UIColor blueColor]; [self.tableView.window addSubview:backgroundView]; [backgroundView release]; I suspect that I am not positioning the backgroundView view in the right place. I have tried sendToBack:, bringToFront:, and others but I always just get a white background. Is it possible to do this from within the UITableViewController? Must I use Interface Builder?

  • UIPageControl design challenge

    - by Sheehan Alam
    My app has a UITabBarController that loads many different UINavigationControllers. I want a UIPageControl to switch between the different UINavigationControllers. Do I place the UIPageControl in my UINavigationController or in my appDelegate? Suggestions and best practices are welcome.

  • Invocation of ViewDidLoad after initWithNibName

    - by live2dream95
    It appears that ViewDidLoad() is sent to a ViewController only after its View is physically displayed (i.e. via NavigationController pushViewController), and not immediately after initWithNibName(). Is this a behavior I can rely on? I would like to get the chance to set the member variables of my view so that all the members are valid by the time ViewDidLoad() is invoked.

  • UITableViewCell is 1px shorter in didSelectRowAtIndexPath than cellForRowAtIndexPath

    - by Calvin L
    I have a UITableViewCell that I create in tableView:cellForRowAtIndexPath:. In that method I call: UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease]; NSLog(@"Cell height: %f", cell.contentView.frame.size.height); This gives me a return value of 44.000000. Then in my tableView:didSelectRowAtIndexPath: method, I call: UITableViewCell *cell = [tableView cellForRowAtIndexPath: indexPath]; NSLog(@"Cell height: %f", cell.contentView.frame.size.height); And this gives me a return value of 43.000000. Aren't they the same cell? What gives?

  • iPhone SDK: Orientation (Landscape and Portrait views)

    - by domness
    Okay, I've got my normal app which is in portrait mode. I can force my app to go to landscape mode for a view (using navigationcontroller and viewcontroller) like this: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; } But then when I go back to the main menu (tableview) it goes straight back to portrait. I try this code: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; } But that doesn't work.. Any ideas?

  • how to play video files by using UITableView?

    - by srikanth rongali
    Hi, In my iPhone application I need to show a video image in UITableView. Each tableViewCell have video and some labels. I used the MPMoviePlayerController for showing video in full screen when the cell is selected. But, I am getting error that MPMoviePlayerController class is not there. I tried using UIWebView. But, I could not make it. How can I play a video, when the cell is selected. Some say that videos do not play in simulator. They only play when we test in device. Is it right ? Please help me with the solution. Thank You.

  • Interface Builder caching bad data (voodoo)

    - by Ryan Townshend
    Sometimes IB will hold onto old or bad references, and I cannot seem to remove or edit them. EDIT I have made this a wiki question with the intention of gathering more data on the phenomenon. Answers involving situations where other coders have encountered this are welcome. This happened to me again last night with a table controller. When I created a spike project to try and reproduce the error, the system worked the way I anticipated. Then back in the actual project the bad behavior continued, even if I remove the xib file and all controllers involved. Creating a whole new project with none of the original (problematic) xib and nib files worked correctly. This question is not about the specifics of this incident but about this type of incident in IB. Does anyone know more about this type of bad IB behaviour, and possibly a more stylish way to to eliminate it than nuking the project? Note, removing the offending IB files and recreating them in the same project has not solved this for me in the past, only whole new projects. Answers regarding examples of when/how this glitch has been observed/created are welcome as well.

  • Block declared variable visible outside?

    - by fuzzygoat
    If I declare a variable within a block (see below) is there a way to specify that its visible outside the block if need be? if(turbine_RPM > 0) { int intResult = [sensorNumber:1]; NSNumber *result = [NSNumber numberWithInt:intResult]; } return result; or is the way just to declare outside the block scope? NSNumber *result; if(turbine_RPM > 0) { int intResult = [sensorNumber:1]; result = [NSNumber numberWithInt:intResult]; } return result; many thanks gary

  • textLabel.backgroundColor on UITableViewCell does not work

    - by Tom
    Hi! I'm trying to set the label backgroundColor of my UITableViewCells and it does absolutely nothing at all. I wonder if there's another way of doing this, so I'm asking! I tried this: cell.textLabel.backgroundColor = [UIColor redColor]; cell.backgroundColor = [UIColor redColor]; And it doesn't work, anything else? Thanks!

  • As-You-Type-Searching with Core Data / NSFetchedResultsController

    - by Snej
    I implemented an as-you-type-searching (text search on single attribute) by fetching with performFetch: after each given character by the user. The performFetch: is running in a background thread to avoid keyboard freezes. But while typing many useless fetches are started. A NSOperationQueue might be an option, but I wonder if there are other approaches for this quite usual search behavior. What's best practice to notice when fetching is done and the table view is updated with the previous fetch to start a new fetch?

    I want to write a small bit of data from my app to the iphone so I can load it when the app next starts. I am going to write the data using NSCoding, but I don't know what I should be specifying as a path.

  • How can I write a scrolling text in cocos2d ?

    - by srikanth rongali
    I have a text and it should be abled to scrolled only up and down to see entire text. and my application is a game and written in cocos2d. So, I have layers. There is also an image(CCSprite) adjacent to text. The text should be scrolled and the image have a touchesEnded: property. I used CCLabel for text and CCParallaxNode to add the text. But the text appears like a continues paragraph. But, my text should have different lines. My text is like this. //text starts Hey Player. Do you want to play the game right now then play. Do you want to practice or Play? what want to do? ...text continues //text ends What should I use for this ? Thank you.

  • Why does presentModalViewController not always work?

    - by E-Madd
    My application requires data from a server in order to run. The first thing it does is displays a view controller (LoadingViewController) that is responsible for checking if the data is saved to my PersistentStoreCoordinator. If the data isn't cached locally, it gets it from my server and caches it, and posts a notification that the LoadingViewController is listening for. When that notification comes through, LoadingViewController presents the application's MainViewController using the presentModalViewController with a flip animation. So far, so good... no errors. However, if the application loads and determines the data IS cached - the presentModalViewController does not work and the main application view never appears. No errors. I've even gone as far as adding a button to the Loading view that executes the same code when pressed and the damn thing works. I'm suspicious it has something to do with the timing of it all but I'm clueless as to what I can do to ensure the view is displayed with that flipping animation if the data is already cached locally. Any suggestions?

  • How do I use a modalViewController Identically in Two Controllers?

    - by Theory
    I'm using the Three20 TTMessageController in my app. I've figured out how to use it, adding on a bunch of other stuff (including TTMessageControllerDelegate methods and ABPeoplePickerNavigationControllerDelegate methods). It works great for me, after a bit of a struggle to figure it out. The trouble I'm having now is a design issue: I want to use it identically in two different places, including with the same delegate methods. My current approach is that I've put all the code into a single class inheriting from NSObject, called ComposerProxy, and I'm just having the two controllers that use it use the proxy, like so: ComposerProxy *proxy = [[ComposerProxy alloc] initWithController:this]; [proxy go]; The go method constructs the TTMessageController, configures it, adds it to a UINavigationController, and presents it: [self.controller presentModalViewController: navController animated: YES]; This works great, as I have all my code nicely encapsulated in ComposerProxy and I need only the above two lines anywhere I want to use it. The downside, though, is that I can't dealloc the proxy variable without getting crashes. I can't autorelease it, either: same problem. So I'm wondering if my proxy approach is a poor one. How does one normally encapsulate a bunch of behaviors like this without requiring a lot of duplicate code in the classes that use it? Do I need to add a delegate class to my ComposerProxy and make the controller responsible for dismissing the modal view controller in a hypothetical composerDidFinish method or some such? Many TIA!

  • How to handle an array of pointers in Objective-C

    - by DougW
    I figured out the answer to this question, but I couldn't find the solution on here, so posting it for posterity. So, in Objective-C, how do you create an object out of a pointer in order to store it in objective-c collections (NSArray, NSDictionary, NSSet, etc) without reverting to regular C?
