  • Can a tab bar controller added to a uitableview?

    - by Sheehan Alam
    I have a View that contains a UITableView and a UITabBarController. I have set my IBOutlets, but the UITabbarController does not appear. Do I need to do anything else to allow it to appear? Note: I don't want the tab-bar to be displayed throughout the entire application. Only on one specific view.

  • 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]; } }

  • 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

  • Animating removeFromSuperview

    - by user230949
    I'd like to animate the transition from a subview back to the super view. I display the subview using: [UIView beginAnimations:@"curlup" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [self.view addSubview:self.mysubview.view]; [UIView commitAnimations]; The above works fine. It's going back to the super view that I don't get any animation: [UIView beginAnimations:@"curldown" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [self.view removeFromSuperview]; [UIView commitAnimations]; Is there something different I should be doing to get the subview to animate when removed?

  • Changing UITableViewCell height on a grouped cell doesn't look good

    - by Sheehan Alam
    I have a UITableView with 3 sections. In the first section I have 2 grouped cells. I am modifying the first cell to be larger than the second. Though the first cell resizes, it seems to mess up the cell below it. How can I resolve this? - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight; if(indexPath.section == kBioSection) { switch(indexPath.row) { case kBioSectionDescriptionRow: rowHeight = 100; break; } } else { rowHeight = 50; } return rowHeight; }

  • How do I get a reference to a rootViewController to a sub-view?

    - by Andy
    An answer posted for one of my previous questions brings up another question; I am calling a new view controller, "RuleBuilder," from my rootViewController. The rootViewController holds a reference to a contacts array. How do I get a reference to that array into the RuleBuilder? I tried adding UITableViewController *rootViewController; ... @property (nonatomic, retain) UITableViewController *rootViewController; to RuleBuilder.h, and then @synthesize rootViewController; in RuleBuilder.m. When I instantiate and push the RuleBuilder from within rootViewController, I do this: ruleBuilder.rootViewController = self; But when I try this [rootViewController.contacts addObject:newContact]; from within RuleBuilder, I get a compiler error to the effect of "request for 'contacts' in something not a struct" (or very similar; I haven't implemented this exact snippet of code, but I tried an identical approach not an hour ago for a couple of different references that I never was able to get working). Thanks, again, for your help.

  • What is a good way for a custom accessory view in a UITableViewCell to message the table view contro

    - by Alex Gosselin
    Hi Everyone, I am working on adding a custom accessory view, (a button) to a UITableViewCell, and I need it to tell the table view when it is touched, but I can't figure out how to communicate to the table view what button was pressed. Ideally I'd like to somehow call a function like this: [controller tableView:view didSelectCustomButtonAtIndexPath:indexPath usingCell:self]; when my custom view button is pressed. Sorry if this is a bit vague, I'm not really sure how to explain this well. I am basically looking for how to mimic the implementation for tableView:didSelectRowAtIndexPath: without having to subclass UITableViewCell. Thanks for any help.

  • How can I create dynamically updated views in a tab bar view, based on settings selection?

    - by Diggers
    Hi all, Noob question.... I've created a Tab Bar application. It has four tabs and works fine. Each view is created with a XIB and is effectively static. Each view takes user input and responds on screen. What I need to be able to do is change the input options the user have - in effect remove some UITextFields dependant upon which option the user selects in settings. I've created root.plist and created settings no problem i've also created additional XIBS for the altered UI, but what I don't know how to do, is call these into the tab view controller on demand. Effectively tab one has 3 possible views, tab two 3 possible views etc. But I only want the one that's relevant for the users settings selction to be displayed? Make sense? For reference, if we call the different views - UIInputViewA1, ...A2,....A3 UIInputViewB1,....B2....B3 etc. Hope someone can help, been trawling the net for nights trying to get my head round this. Beggining iPhone Development Bible doesn't help either. If you need any more info, please shout. Cheers Paul.

  • Improving the efficiency of multiple concurrent Core Animation animations

    - by Alex
    I have a view in my app that is very similar to the month view in the built-in Calendar app. There's a subview that holds the individual cells (a custom UIView subclass that draws text into its layer), and when the user navigates to the next "month", I create the new cells and slide the view to show them. When the animation stops, I remove the old, hidden cells and set things up so it's ready to go for the next animation. This all works nicely. However, I'd like to animate the cells' text color, as in the Calendar app, so that the outgoing ones transition to a lighter color and the incoming ones transition to a darker color. The problems is that I can have as many as 70 cells, so doing individual animations is very slow -- between 5-10 fps on my iPhone 3GS. I'm trying to find a less computationally intense way of doing this. My reading of the Shark results is that the majority of the time is spent redrawing the text for each frame for each frame. This makes sense, since text rendering is hardly the cheapest operation. I've considered creating a second view -- one holding the "outgoing" state and one holding the "incoming" state and using a single opacity animation to gradually reveal the updated cells while both are sliding. I'm concerned that instead of having 70 cells, I'll have 140, which seems like a lot of views. So, is that too many views or would there be a better way of doing this?

  • How do I push a new controller via UIButton, nested in a UIScrollView?

    - by jimijon
    Hello - I have my views that are part of a tabBar. Each view has a navigationController. In one of my views I have an embeded xib component. This is a scrolling view with UIButtons inside it. I want to slide in another view, inside the navigationController when a person taps the button. I can get the taps, etc. BUT, I can't figure out how to find the controlling navigationController of that page to push the new view into. Nothing seems to work that I have tried. IS this possible? Thanks

  • UITextField for Phone Number

    Hello everyone, I was wondering how I can format the textField that I'm using for a phone number (ie like the "Add New Contact" page on the iPhone. When I enter in a new mobile phone, ex. 1236890987 it formats it as (123) 689-0987.) I already have the keyboard set as the number pad. Thanks!

So I could not see any label in my table. How can I make this ? Thank You

  • Which icons/buttons to use for help, about, info?

    - by 4thSpace
    I use the info button to display a settings page. This page is a modal. I need another button from here to display "About" info, since I've already used "info" for something. I have a search form that is accessed only from the modal. On the search form, I need a help icon. I can use the info button but that seems confusing, since I already use the info button from the main view to access the modal. What else can I do for help and about icons/buttons?
