  • iPhone: Use a view as a transparent overlay with closing button

    - by axooh
    I've got a map with three bar buttons for different markers to show up in the map. If I click on a bar button, the specific markers are shown in the map, which already works great. Now I would like to show a transparent overlay (popup window) with the description of the markers after I clicked on a bar button with a button to close the overlay again and show the markers (which are set in the background). The function of the bar button: - (IBAction)routeTwo:(id)sender { // The code for the overlay // ... // remove any annotations that exist [map removeAnnotations:map.annotations]; // Add any annotations which belongs to route 2 [map addAnnotation:[self.mapAnnotations objectAtIndex:2]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:3]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:4]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:5]]; } I tried the following possibilities: 1. Using a modal view controller RouteDescriptionViewController *routeDescriptionView = [[RouteDescriptionViewController alloc] init]; [self presentModalViewController:routeDescriptionView animated:YES]; [routeDescriptionView release]; Works great, but the problem is: The map view in the background is not visible anymore (configuring alpha values of the modal view doesn't change anything). 2. Add RouteDescriptionView as a subview RouteDescriptionViewController *routeDescriptionView = [[RouteDescriptionViewController alloc] init]; [self.view addSubview:routeDescriptionView.view]; [routeDescriptionView release]; Works great as well, but the problem here is: I can't configure a close button on the subview to close/remove the subview (RouteDescriptionView). 3. Using UIAlertView Would work as expected, but the UIAlert is not really customizable and therefore not suitable for my needs. Any ideas how to achieve this?

  • UIAlertViewDelegate clickedButtonAtIndex: usefulness?

    - by Ed Marty
    The UIAlertViewDelegate protocol defines two methods, alertView:clickedButtonAtIndex: and alertView:didDismissWithButtonIndex:, which seem to me to be identical in usefulness. Why is there a clickedButtonAtIndex and a didDismissButtonWithIndex when they both do the same thing? I realize there is also a willDismissButtonWithIndex that happens before the alert view is dismissed, but is there any reason to use clickedButtonAtIndex instead of didDismissButtonWithIndex?

  • Which audio playback technology do I need for this?

    - by mystify
    I have trouble choosing the right audio playback technology. There's a ton of technologies to use on the iPhone, it's so confusing. What I need to do is this: start playing short sounds ranging between 0.1 and 2 seconds high quality playback, no crackle (I heard some of the iPhone audio playback technologies do a crackle sound on start or end, which is bad!) ability to start playback of a sound, while there's already another one playing right now (two, three or more sounds at the same time) What would you suggest here, and why? Thanks :-)

  • UILabel: Using the userInteractionEnabled method on a label

    - by Kevin Bomberry
    Hello again. I am wondering if anyone has used the userInteractionEnabled method on a UILabel to allow the label to act like a button (or just to fire off a method). Any help would be greatly appreciated. Cheers! Update (4/30/09 @1:07pm) Clarification: I have a standard InfoButton and next to it I want to place a label with the text "settings" and I would like the label to function like the button (which flips over to a settings screen. So, basically I need to tie the already defined showSettinsView to the "infoLabel" label; a user clicks on the infoButton or infoLabel and the method fires off. The infoButton is already working and is using an IBAction to trigger the method. I would like to know how to wire up the label to implement the same method. That is all. Cheers!

  • Why aren't Admob click callback delegate methods getting called?

    - by executor21
    I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help. EDIT: removed the double negative from the question title

  • Changing UINavigationBar font in Swift

    - by dcgoss
    I have a UINavigationBar with a title in the middle. I have added a custom font ("Comic_Andy.ttf") to my app (I have checked info.plist to make sure it's listed, and I have checked the Copy Bundle Resources to make sure it has been added), and I would like the title of the UINavigationBar to be displayed in that font. From what I can gather it seems as though I'm supposed to use this in my ViewController: myNavigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I placed that method in the viewDidLoad function of the ViewController. I have also tried this in the didFinishLaunchingWithOptions function of the AppDelegate: UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I am programming in Swift, in XCode 6 Beta 6. Many resources regarding this task have mentioned using a method called setTitleTextAttributes, which is nowhere to be seen. I can't figure it out for the life of me - I've probably spent close to 3 hours on it by now - I have checked every StackOverflow answer, every website, so please do not mark this as a duplicate. Many thanks in advance!

  • Custom UITableViewCell not appearing when row height is set

    - by Sheehan Alam
    I have a custom UITableViewCell which I have created in IB. My labels display when I don't over-ride: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath however my content is squished. I want the height to be 120px so I have the following: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight = 120; return rowHeight; } I'm not sure why the content inside of my UITableViewCell all of a sudden disappears?

  • Is there an easy way to make a horizontally paged UIScrollView wrap around?

    - by rustyshelf
    I notice that in the stocks application, the small graph wraps around, eg: when you get to the end of the scroll view and swipe right again, you go back to the beginning. Before I go ahead and code this myself is there an easy way to do this in the SDK? I can't find any properties or methods that would enable that? I have a paged UIScrollView that scrolls horizontally, pretty much exactly like the stocks application one does.

  • How to use generic (NSObject) controller with subviews of a UIViewController?

    - by wanderlust
    I have a UIViewController that is loading several subviews at different times based on user interaction. I originally built all of these subviews in code, with no nib files. Now I am moving to nib files with custom UIView subclasses. Some of these subviews display static data, and I am using loadNibNamed:owner:options: to load them into the view controller. Others contain controls that I need to access. I (sort of) understand the reasons Apple says to use one view controller per screen of content, using generic controller objects (NSObjects) to manage subsections of a screen. So I need a view controller, a generic controller, a view class and a nib. How do I put this all together? My working assumptions and subsequent questions: I will associate the view class with the nib in the 'class identity' drop down in IB. The view controller will coordinate overall screen interactions. When necessary, it will create an instance of the generic controller. Does the generic controller load the nib? How? Do I define the outlets and actions in that view class, or should they be in the generic controller? How do I pass messages between the view controller and the generic controller? If anyone can point me to some sample code using a controller in this way, it will go a long way to helping me understand. None of the books or stackoverflow posts I've read have quite hit the spot yet.

  • Assigning a selector via SEL type?

    - by fuzzygoat
    I just spotted the following in an online tutorial. It showed 001 as a method for assigning a selector, however I could not get this to work. Am I right in thinking that 001 is not right and 002 is the correct way, or am I doing something wrong with 001? // 001 SEL mySel = [self something]; // 002 SEL mySel = @selector(something); . -(void)something { NSLog(@"YAY"); } Gary

  • How do I allow users to dial numbers in my tableView cells?

    - by Griffo
    Hi all, I have a table containing cells with phone numbers. How can I allow the user to dial these numbers by tapping the row? It's not working by default and there's no option in interface builder like there is for uiwebviews so I imagine I need to programmatically tell the app to dial the number when the cell is tapped.

  • Can I create a UITableViewController that inherits from a custom subclass of UIViewController?

    - by prendio2
    I have common functionality that I need to access from all screens of my app: a right bar button item and associated action. So as not to repeat the code I would like to set this up in a custom UIViewController and have all my view controllers inherit from it. - (void)viewDidLoad { UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:@selector(lightsCamera)]; self.navigationItem.rightBarButtonItem = rightBarButton; } - (void)lightsCamera { … } However, I have a number of UITableViewControllers however and I would like to know if it is possible for them to inherit the functionality too?

  • Get Object ID of UI element from code.

    - by andoriyu.mp
    I'm trying link 40 buttons to one event handler method and then do the processing work from one method instead of 40. I know how to link it but once I get there I don't know how to distinguish what button was pressed. Does anyone know how to reference the button object sender id or is there another way to solve this problem? Any help would be greatly appreciated.
