  • Reorder cells in a UITableView without displaying a "delete" button

    - by iter
    I want to be able to reorder cells in a table, but not to delete or insert them. I want a picture like this: This image appears in Apple's Table View Programming Guige, but the code samples there produce a table with red "delete" buttons when the table goes into editing mode. I can set editingStyleForRowAtIndexPath to UITableViewCellEditingStyleNone and that makes the delete buttons go away, but the rows are still indented as if to make room for these buttons.

  • Orientation in a UIView added to a UIWindow

    - by Ken
    OK, bear with me. I have a UIView which is supposed to cover the whole device (UIWindow) to support an image zoom in/out effect I'm doing using core animation where a user taps a button on a UITableViewCell and I zoom the associated image. The zooming is performing flawlessly, what I haven't been able to figure out is why the subview is still in portrait mode even though the device is in landscape. An illustration below: http://www.weeshsoft.com/images/IMG_0482.jpg I do have a navigation controller but this view has been added to the UIWindow directly. Signed, Baffled in Atlanta

  • Blackberry support for Forms Authentication - ASP.NET MVC app

    - by Derek Mitchell
    I'm writing an ASP.NET MVC application that uses Forms Authentication. The target clients are a variety of mobile web browsers. When I use the BlackBerry 8530 simulator my MVC app authenticates as expected. I can visit pages whose controller methods are decorated with the [Authorize] attribute - no problem - they display and therefore I assume my Forms Authentication is working correctly. Using a physical Windows Mobile device to browse my site, I have the same experience as the BB simulator, the forms authentication works as I would expect. BUT when I try to visit the site using a Blackberry 8900 physical device the Login page keeps on looping back when I click the Login page. The device is not retaining it's "authenticated" status. I added code to verify this and I can see that: Request.IsAuthenticated: False User.Identity.IsAuthenticated: False So my question is what next steps can I take to try and find out why the Blackberry 8900 is losing it's authentication status. Is this cookie related? Anyone have any ideas? Cheers Derek

  • How to create a UIScrollView Programmatically?

    - by Wayfarer
    Alright, so the key here is I'm not using IB at all, because the View I'm working with is created programmatically. The UIView covers the lower half the screen, and has a bunch of buttons on it. However, I want to add more buttons to the UIView, without making it any larger. To do so, I want to make a UIScrollView inside the view, which will allow me to add more buttons off screen so the user can scroll to them. I think that's how it works. self.manaView = [[[UIView alloc] initWithFrame:frame] autorelease]; self.manaView.backgroundColor = [UIColor purpleColor]; UIScrollView *scroll = [UIScrollView alloc]; scroll.contentSize = CGSizeMake(320, 400); scroll.showsHorizontalScrollIndicator = YES; [self.manaView addSubview:scroll]; The first part of the code iniates my UIView, which works great, but I can't figure out how to make the UIScrollView programmatically and add it to the view, and then add the buttons to it. UIButton *ret2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; ret2.tag = 102; ret2.frame = CGRectMake(255, 5, 60, 50); [ret2 setTitle:@"Return" forState:UIControlStateNormal]; [ret2 addTarget:self action:@selector(flipAction:) forControlEvents:UIControlEventTouchUpInside]; [scroll addSubview:ret2]; When I did that, the button simply disappeared off my screen. So How do I do this correctly? Thank you for your help!

  • How to popViewController from button click of custom UITableViewCell

    - by Chi Rod
    I have a button in a custom UITableViewCell. Its UITableView is controlled by a UIViewController. I would like to return to the RootView when that button is clicked. I am trying to use [self.superview.navigationController popViewControllerAnimated:YES]; in the target Action of the button, which is in the UITableViewCell.m file. However, it doesn't recognize "navigationController" because it is not in the stack. How can I return to the RootView when that button is clicked?

  • memory warning, generating UIImagefrom pdf files in objective-c

    - by favo
    When converting PDF Pages into UIImages I receive memory warnings all the time. It seems there is either some leak or something else that eats my memory. Using instruments didn't give me any helpful details. I'm using the following function to generate images from a pdf file: - (UIImage*)pdfImage:(NSString*)pdfFilename page:(int)page { CFURLRef pdfURL = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, (CFStringRef)pdfFilename, kCFURLPOSIXPathStyle, false); CGPDFDocumentRef pdfRef = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CFRelease(pdfURL); CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfRef, page); CGRect pdfPageSize = CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox); float pdfScale; if ( pdfPageSize.size.width < pdfPageSize.size.height ) { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.width; } else { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.height; } CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, pdfPageSize.size.width*pdfScale, pdfPageSize.size.height*pdfScale, 8, (int)pdfPageSize.size.width*pdfScale * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); // CGContextClipToRect(context, pdfPageView.frame); // CGPDFPageRetain(pdfPage); CGAffineTransform transform = aspectFit(CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox), CGContextGetClipBoundingBox(context)); CGContextConcatCTM(context, transform); CGContextDrawPDFPage(context, pdfPage); // CGPDFPageRelease (pdfPage); CGImageRef image = CGBitmapContextCreateImage(context); CGContextRelease(context); UIImage *finalImage = [UIImage imageWithCGImage:image]; CGImageRelease(image); CGPDFDocumentRelease(pdfRef); return finalImage; } I am releasing the document and everything else, so where could be the problem? Thanks for your help!

  • Problem with Rotating a UIScrollview

    - by leachianus.gecko
    Hey guys, I am having issues trying to get the pageControl sample code to work with rotation. I managed to get it to rotate but it does not visually loads correctly until I start to scroll (then it works fine). Any Idea on how I can fix this problem? Here is a link to the project if you want to see it in action. This code is based off the PageControl example apple has provided. here is the code: #import "ScrollingViewController.h" #import "MyViewController.h" @interface ScrollingViewController (PrivateMethods) - (void)loadScrollViewWithPage:(int)page; @end @implementation ScrollingViewController @synthesize scrollView; @synthesize viewControllers; - (void)viewDidLoad { amount = 5; [super viewDidLoad]; [self setupPage]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [scrollView release]; } - (void)dealloc { [super dealloc]; } - (void)setupPage { NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < amount; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; // a page is the width of the scroll view scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * amount, 200); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; [self loadScrollViewWithPage:0]; [self loadScrollViewWithPage:1]; } #pragma mark - #pragma mark UIScrollViewDelegate stuff - (void)scrollViewDidScroll:(UIScrollView *)_scrollView { if (pageControlIsChangingPage) { return; } /* * We switch page at 50% across */ CGFloat pageWidth = _scrollView.frame.size.width; int dog = floor((_scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; // pageControl.currentPage = page; [self loadScrollViewWithPage:dog - 1]; [self loadScrollViewWithPage:dog]; [self loadScrollViewWithPage:dog + 1]; } - (void)loadScrollViewWithPage:(int)page { if (page < 0) return; if (page >= amount) return; MyViewController *controller = [viewControllers objectAtIndex:page]; if ((NSNull *)controller == [NSNull null]) { controller = [[MyViewController alloc] initWithPageNumber:page]; [viewControllers replaceObjectAtIndex:page withObject:controller]; [controller release]; } if (nil == controller.view.superview) { CGRect frame = scrollView.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [scrollView addSubview:controller.view]; } } - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { [self setupPage]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } #pragma mark - #pragma mark PageControl stuff @end

  • Memory management for NSURLConnection

    - by eman
    Sorry if this has been asked before, but I'm wondering what the best memory management practice is for NSURLConnection. Apple's sample code uses -[NSURLConnection initWithRequest:delegate:] in one method and then releases in connection:didFailWithError: or connectionDidFinishLoading:, but this spits out a bunch of analyzer warnings and seems sort of dangerous (what if neither of those methods is called?). I've been autoreleasing (using +[NSURLConnection connectionWithRequest:delegate:]), which seems cleaner, but I'm wondering--in this case, is it at ever possible for the NSURLConnection to be released before the connection has closed?

  • UIViewAnimationTransition and landscape

    - by moor
    Hi! I'm having a problem with UIViewAnimationTransitionCurlUp and landscape mode. In my landscape application I have a view controller that manages two fullscreen views. In the controller I have a container view for the transitions. To switch between the two views, I use a curled transition but the animation is performed as if it were in portrait mode. I have setted the UIDeviceOrientation in info.plist, also the supported orientations to both landscape right and left. The controller returns true in shouldAutorotateToInterfaceOrientation only for landscape right and left. I have also tried to start the controller and views with 480 width and 320 height manually. I dont know where is the problema and dont know what else to try. Could someone help me? Thank you!

  • writing NSDictionary to plist

    - by ADude
    Hi I'm trying to write an NSDictionary to a plist but when I open the plist no data has been written to it. From the log my path looks correct and my code is pretty standard. Any ideas? NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", @"key3", nil]; NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", @"value3", nil]; NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys]; for (id key in dictionary) { NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]); } NSString *path = [[NSBundle mainBundle] pathForResource:@"FormData" ofType:@"plist"]; NSLog(@"path:%@", path); [dictionary writeToFile:path atomically:YES];

  • UISearchBar delegate not called when used as UINavigationBar titleVIew?

    - by phooze
    I have a UITableViewController that I have specified as a UISearchBarDelegate. Up until now, I had programmatically added the UISearchBar to the headerView of the table, and there were no problems. I began to run out of screen real estate, so I decided to kill my normal UINavigationController title (which was text), and added the following code, moving my SearchBar from the table to the UINavigationBar: // (Called in viewDidLoad) // Programmatically make UISearchBar UISearchBar *tmpSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,45)]; tmpSearchBar.delegate = self; tmpSearchBar.showsCancelButton = YES; tmpSearchBar.autocorrectionType = UITextAutocorrectionTypeNo; tmpSearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone; [self set_searchBar:tmpSearchBar]; [tmpSearchBar release]; self.navigationItem.titleView = [self _searchBar]; This code works as expected - my UINavigationBar is now a UISearchBar. However, my delegate method: /** Only show the cancel button when the keyboard is displayed */ - (void) searchBarDidBeginEditing:(UISearchBar*) lclSearchBar { lclSearchBar.showsCancelButton = YES; } ...is no longer being called. I've breakpointed, and I've confirmed that the UISearchBar's delegate is indeed self, the view controller. Oddly, this delegate method is still called just fine: /** Run the search and resign the keyboard */ - (void) searchBarSearchButtonClicked:(UISearchBar *)lclSearchBar { _deepSearchRan = NO; [self runSearchForString:[[self _searchBar] text] isSlowSearch:NO]; [lclSearchBar resignFirstResponder]; } Any ideas why UINavigationBar is swallowing my delegate calls?? What am I missing?

  • UIWebView not loading URL when URL is passed from UITableView

    - by Mark Hazlett
    Hey Everyone, So i'm building a webView into my application to show the contents of a URL that I am passing from a selection in a UITableView. I know the UIWebView is loading content properly because if you hard code say http://www.google.ca into the NSURL then it loads fine, however when I'm passing the URL that I parsed from an RSS feed back from the UITableView it won't load the URL properly. I tried the debugger and the URL is coming out as nil right before I try and parse it, however I can use NSLog to print the value of it out to the console. here's the code in my UIViewController that has my UIWebView #import <UIKit/UIKit.h> @interface ReadFeedWebViewController : UIViewController { NSString *urlToGet; IBOutlet UIWebView *webView; } @property(nonatomic, retain) IBOutlet UIWebView *webView; @property(nonatomic, retain) NSString *urlToGet; @end Here's the code for my implementation's viewDidLoad method... // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"Url inside Web View Controller - %@", urlToGet); NSURL *url = [NSURL URLWithString:urlToGet]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:requestObj]; } Once again, I can print the URL to NSLog fine and if I hard code the URL into the NSURL object then it will load fine in the UIWebView. Here is where I'm setting the value in my UITableViewController... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { ReadFeedWebViewController *extendedView = [[ReadFeedWebViewController alloc] init]; int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; extendedView.urlToGet = [[stories objectAtIndex: storyIndex] objectForKey:@"link"]; //NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"summary"]); NSLog([[stories objectAtIndex: storyIndex] objectForKey:@"link"]); [self.navigationController pushViewController:extendedView animated:YES]; [extendedView release]; } However, since I can print the value using NSLog in the extendedView view controller I know it's being passed properly. Cheers
