  • Resizing the imageView in a UITableView

    - by Luca
    Hi! I Created a grouped table view, and I noticed that placing an image in the imageView results in an image that is too large. It overlaps the rounded borders of the cell, which is horrible. I tried looking for a way to resize it, but I found many answers that didn't quite satisfy me. How would you do this? Which is the simplest way to go? The solutions I found where strangely complicated. Thanks!

  • Image is not detected if taken from camera Using UIImagePickerControllerSourceTypeCamera

    - by user1314379
    I am trying to build an app which will compare the two images and gives the Matching Percentage. I am taking two Images from The camera(Making use of UIImagePickerController) and saving it to the document directory.Then i fetch these images in a different view controller to get the face part, using CIDetector API and CIfacefeature API. The problem is It is not detecting the face at all through i am able to fetch the images properly. And if i store the same image in the main bundle it detects. I dnt know where the problem is. I have tried everything. May Be the problem is with the UIImage or may be the format in which image is getting saved in document directory or with the camera. Please help. I will be grateful to you. Thanks in Advance.

  • Need help with text animation within UITableViewCell

    - by gdiphone
    I'm trying to implement a simple text animation in a custom UITableViewCell without having to go into editing mode which automatically brings up the delete button on the right. What I'm trying to accomplish is that when the label is updated by a button within the UITableviewcell, the text in the label is updated but with some smooth animation like sliding to the right since the updated text is prepended to the string. Any sample code would be great. thanks

  • How do I reference a pointer from a different class?

    - by Justagruvn
    First off, I despise singletons with a passion. Though I should probably be trying to use one, I just don't want to. I want to create a data class (that is instantiated only once by a view controller on loading), and then using a different class, message the crap out of that data instance until it is brimming with so much data, it smiles. So, how do I do that? I made a pointer to the instance of the data class when I instantiated it. I'm now over in a separate view controller, action occurs, and I want to update the initial data object. I think I need to reference that object by way of pointer, but I have no idea how to do that. Yes, I've set properties and getters and setters, which seem to work, but only in the initial view controller class. Peace Love applesauce.

  • Why won't my UITableViewCell deselect and update its text?

    - by Josh
    I have a UITableView with a list of stories and a cell at the bottom that loads more stories. I am trying to make the "More Stories..." cell deselect and change its text to "Loading..." when clicked. I have searched all over the internet and all over stackoverflow and I cant figure out why my code isnt working right. Right now, when the "More Stories..." cell is clicked, it stays selected and doesnt ever change its text. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; if (storyIndex == [stories count]) { UITableViewCell *moreCell = [tableView dequeueReusableCellWithIdentifier:@"more"]; if (moreCell == nil) { moreCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"more"] autorelease]; } // Set up the cell moreCell.textLabel.text = @"Loading..."; [tableView deselectRowAtIndexPath:indexPath animated:YES]; [self moreStories]; } else { NSLog(@"%@",[[stories objectAtIndex: storyIndex] objectForKey: @"link"]); webViewController *webController; webController = [[webViewController alloc] initWithURLPassed:[[stories objectAtIndex: storyIndex] objectForKey: @"link"]]; [self.navigationController pushViewController:webController animated:YES]; [webController release]; webController =nil; self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil]; } }

  • aspectRatio = backingWidth / backingHeight ???

    - by carrots
    What am I doing wrong here, I can't get the result of this division: aspectRatio = backingWidth / backingHeight; I've thought I might try casting to (GLfloat) but that didn't do anything. As I step through the code I see that aspectRatio is 0 after the operation, while backingWidth is clearly 768 and backingHeight is 1029. Here are the types: GLfloat aspectRatio; and // The pixel dimensions of the CAEAGLLayer GLint backingWidth; GLint backingHeight; It must be something basic I'm doing wrong here..

  • Load all tab bar views when application first runs

    - by codenoobie
    Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

  • titleForHeaderInSection is not updating Section Header information correctly

    - by Jim
    I have two tableviews where one navigates to the next. Both use more or less the same code and use the managedObjectContext and FetchedResultsController design pattern to provide the relevant data for both tables. My problem happens when I navigate from the first to the second tableview and the data has only one Section Header / Row in the tableview. The data will then not update Section Header information. It does when there is more than one row but not if there is only one row. It leaves the information from the first attempt in place. I can confirm the row data is correct so the relevant data should be being passed to the Section Header correctly but it isn't. Has anyone else come across this problem?

  • Time in "Upload Received"

    - by rpeck1682
    I uploaded an app to itunes connect yesterday afternoon. It has been in the "Upload Received" stage ever since then. I uploaded a different app today, it was in that stage for only five minutes. This is the first time I've submitted since the new, more detailed status updates were present. I'm just wondering if the app sitting there in that state for so long seems like something to be concerned about. I'm guessing by staying in that state that it isn't being put on the review queue. Anyways, has anyone else had a similar experience?

  • how to create a custom settings view / make cell label editable

    - by Lex
    Hi everyone, I need to create a custom settings view used within the app. The app is a mockup so it actually does have one already, it uses a UITableViewCellStyleValue1, but nothing is editable. So essentially what I would like to have is the same thing but with editable detailTextLabel (the label on the right hand side), what's the best way to do this?

  • How can I make a view get bigger again, as soon as the status bar goes back to normal height after a

    - by Thanks
    In the simulator I went to Hardware menu and activated the simulation of bigger status bar during phone call. Now, I tried to make a view in my nib that takes up the whole screen. As soon as the status bar gets smaller, I want my view to get bigger, so it uses that space up there. But regardless of any autoresizing settings, my view will keep pressed down after that status bar gets smaller. There is a empty slot left where the status bar was after hanging up the call. What's that actually supposed to be? Is my app recognizing the status bar as a view, or is the status bar indeed making my screen smaller? I mean...does it mess around with my views as if it was a view itself, or do my views not know about a status bar, but about a smaller screen size when the status bar gets bigger? How do you get your views big again when the status bar returns to normal height?

  • Application to download video from youtube

    - by Nidal Saed
    I making an application to view videos form youtube, and I think it is very easy to write a code to make the user be able download the videos and save it in the documents folder of the application, my questions are: 1) is it legal to do this, and is there any concern of the application being rejected? 2) is it possible to make the user watch the video and when he finish (watched all the video) get this data and save it, (not to download it again since he already watched the video and downloaded it).

  • Graph not following orientation

    - by user1214037
    so I am trying to draw some grid lines that in landscape go all the way down to the bottom, however when I switch to landscape the the graph doesn't follow and the grid lines go smaller. I have set the - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } However it still doesn't work, here is my code. Can anyone spot the problem? this is the custom view file, the view controller is the default apart from the code above that returns yes. .h file #import <UIKit/UIKit.h> #define kGraphHeight 300 #define kDefaultGraphWidth 900 #define kOffsetX 10 #define kStepX 50 #define kGraphBottom 300 #define kGraphTop 0 @interface GraphView : UIView @end And here is the implementation - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 0.6); CGContextSetStrokeColorWithColor(context, [[UIColor lightGrayColor] CGColor]); // How many lines? int howMany = (kDefaultGraphWidth - kOffsetX) / kStepX; // Here the lines go for (int i = 0; i < howMany; i++) { CGContextMoveToPoint(context, kOffsetX + i * kStepX, kGraphTop); CGContextAddLineToPoint(context, kOffsetX + i * kStepX, kGraphBottom); } CGContextStrokePath(context); } Any help would be appreciated btw I am following this tutorial http://buildmobile.com/creating-a-graph-with-quartz-2d/#fbid=YDPLqDHZ_9X

    - by zp26
    Hi, I have a prblem with my code. I have a viewController and a singleton class. When i call the method readXml and run a for my program update the UITextView. When i call the clearTextView method the program exit with EXC_BAD_ACCESS. The prblem it's the name of the variable position. This is invalid but i don't change anything between the two methods. You have an idea?

  • UIActionsSheet text shadow problem

    - by AlexVogel
    I have a problem with the text shadow of the UIActionSheet buttons. At iOS 4.0.2 long string were truncated automatically. No at iOS 4.2 these texts are presented with a smaller font. But now the offset of the shadow is corrupted and to big. Is there a possibility to change/remove the text shadow of the UIActionSheet. EDIT: I'm building the UIActionSheet not with initWithTitle:, but with the normal init and sets all needed properties afterwards because the number of possible buttons is dynamic and the texts cannot be change. I've tested it with initWithTitle: and got the same results.
