  • Adding a UILabel to a UIToolbar

    - by Boolean
    I'm trying to add a label to my toolbar. Button works great, however when I add the label object, it crashes. Any ideas? UIBarButtonItem *setDateRangeButton = [[UIBarButtonItem alloc] initWithTitle:@"Set date range" style:UIBarButtonItemStyleBordered target:self action:@selector(setDateRangeClicked:)]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, 20, 20)]; label.text = @"test"; [toolbar setItems:[NSArray arrayWithObjects:setDateRangeButton,label, nil]]; // Add the toolbar as a subview to the navigation controller. [self.navigationController.view addSubview:toolbar]; // Reload the table view [self.tableView reloadData];

  • Static keyboard in uitableview

    - by Martin
    I have a UITableView that holds just two cells with a textfield in each. As my tableview is just for editing the text in these textfields I always want the keyboard to be shown static in the bottom of the screen. So in viewDidLoad I set the first textfield to become first responder. Something I have noticed though is that when I push the UITableViewController into the UINavigationController the keyboard show up a little bit slower so you can see it animate into the screen. It would be much better if it was there already there when the uitableview shows up. I also tried making the textfield first responder before pushing it as recommended but that didn't made the keyboard show at all: MyTableViewController *myTableViewController = [[MyTableViewController alloc] initWithNibName:@"MyTableViewController" bundle:nil]; [myTableViewController.textField becomeFirstResponder]; [self.navigationController pushViewController:myTableViewController animated:YES]; [myTableViewController release]; How can I accomplish this? Thanks!

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • Why is my view not resizing after rotating?

    - by E-Madd
    I'm only supporting the portrait orientation, but both the right-side-up and upside-down versions. Why do my subviews not resize appropriately? There's a status bar sized black space at the top of the view. If I change tabs and come back, it's corrected.

  • Is there a way to get the current UIEvent being handled?

    - by not-
    I'm working in a class that is a delegate of another class; this other class is in a third-party library that I'd like to avoid changing if at all possible. The original class is handling a -touchesEnded event, and is delegating responsibility to me, but it doesn't pass the UIEvent itself to me. Is there a way to get a handle to the current event in progress? It's a double-tap handler, and all that is passed to me is the view being touched, and the point at which the touch occurred. I want to know exactly how many touches are involved in the event. Thanks! randy

  • Creating a button on a View from a second View

    - by BigJoke
    Hi, I have this app I'm working on, which on a second view asks (textfield) the name for a button to be created on first view. After specifying the name and pressing OK button, the first view pops up (as demanded) but there's no new button, although created indeed. Can I use the following code in a second view method, to "refresh" the first view before presenting itself. What's wrong with this code? Any other approach? Thank you. -(void)initWithView:(View1Controller *)aSuperview { theSuperview = aSuperview; } - (IBAction)itemNameButton { ... CGRect rectang; rectang = CGRectMake(0, 0, 320, 460);// just in case [theSuperview.view setNeedsDisplayInRect:rectang]; ... }

  • How do I change the background image of my app?

    - by user356387
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • UITextField in UITableViewCell Help

    - by W Dyson
    Hello All, I have scoured the internet looking for a good tutorial or posting about having a UITableView populated with a UITextField in each cell for data entry. I want to keep track of each UITextField and the text written within it while scrolling. The tableView will be sectioned. I have been using a custom UITableViewCell but I'm open to any method. Also, is it possible to use the textFields as ivars? If any of you could point me in the right direction, it would be greatly appreciated. Thank you in advance!

  • UIView rotate and than move

    - by user1790354
    I have problem with rotating and moving image (UIView). If I use this for rotate: [UIView beginAnimations: @"rotate" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.transform = CGAffineTransformMakeRotation (angle); // spaceShip is the UIView [UIView commitAnimations]; And this to move: [UIView beginAnimations: @"move" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.center = destanation // destanation is a point where user tap [UIView commitAnimations]; It's working well one at a time. But together this two animations don't work. Space Ship is rotating, but does not move in direction. Where my mistake? P.S. Early I have specify anchor point (0.5, 0.5). But when I rotate image it coordinates is changing.
