• Packaging a Bundle with a static library

  - by 4thSpace

  I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

• Android customizing ViewFlipper...

  - by wearysamurai

  So I'm having pretty much exactly the problem described here: http://code.google.com/p/android/issues/detail?id=6191 and until the ViewFlipper issue in 2.1 and 2.2 has been resolved, I'm attempting to customize my own ViewFlipper in the manner described: @Override protected void onDetachedFromWindow() { try { super.onDetachedFromWindow(); } catch (IllegalArgumentException e) { // Call stopFlipping() in order to kick off updateRunning() stopFlipping(); } } But I've never done this sort of thing before and am hoping to get a little guidance (as my own efforts are coming up short). Here's what I have so far. FixedFlipper.java: import android.content.Context; import android.util.AttributeSet; import android.widget.ViewFlipper; public class FixedFlipper extends ViewFlipper{ public FixedFlipper(Context context){ super(context); } public FixedFlipper(Context context, AttributeSet attrs){ super(context, attrs); } @Override protected void onDetachedFromWindow(){ try{ super.onDetachedFromWindow(); }catch(Exception e){ super.stopFlipping(); } } } main.xml: <com.site.TestApp.FixedFlipper style="@style/body" android:id="@+id/flipper"> ... </com.site.TestApp.FixedFlipper> And in my activity, I invoke it like so: FixedFlipper flipper = (FixedFlipper)findViewById(R.id.flipper); It seems like it should be pretty straightforward, but I keep getting this: Binary XML file line #4: Error inflating class com.site.TestApp.FixedFlipper I appreciate any suggestions. I've been chasing my tail for hours trying to figure out what piece of the puzzle I'm missing.

• How do I reduce the height of a TableView when it is constructed in IB?

  - by erotsppa

  I wanted to add a view to the bottom of my screen. The controller is a UITableViewController, how do I shrink the tableView and add a extra view at the bottom of the tableview? I've tried setting the frame of self.tableView in different places (viewDidLoad, viewWillAppear etc) but nothing happens. The tableView is created by IB and not programtically. I've tried added a footer to my table view but that's not what I want, because the footer actually scrolls up, I want a static non moving View at the bottom of the screen.

• Stop Progressbar manual scrolling in Android

  - by Rony

  Hi experts, I have already posted my query here, but unfortunately, not getting the required support for this simple query. http://www.anddev.org/prevent_manual_moving_of_seekbar_widget-t13048.html I am using progressbar widget in my application to show the download progress. In the current state, I am able to manually move the slider back and forth while download is progressing. How can I prevent the manual moving of progressbar, instead it works only based on progressbar.setProgress(progressbar.getProgress() + 1024); -- currently this works perfect, but I need to prevent the manual moving of progressbar during download. Any help in this regard is appreciated. Regards, Rony

• UITableViewCellStyleValue2 edit indicators?

  - by Jason Jardim

  I am using this style of table view UITableViewCellStyleValue2. I set editing, but I cant seem to get the arrows to show up on the right of the cell - like the Contacts app. Also in the contacts app I notice that if I have a Favorite it puts a * (star) to the right. Any info on how to get an image would be appreciated. Thanks!

• Core Data vs. SQLitePersistentObjects

  - by Macatomy

  I'm creating an iPhone app and I'm trying to choose between 2 solutions for a persistent store. Core Data, or SQLitePersistentObjects. Basically, all my app needs is a way to store an array of model objects and then load them again to display in a UITableView. Its nothing too complicated. Core Data seems to have a much higher learning curve than the simple to use SQLitePersistentObjects. Are there any obvious benefits of using Core Data over SQLitePersistentObjects in my case?

• How do I create a UISplitView manually?

  - by Mark

  I have an app that is going to navigate to a UISplitView (inside another view altogether) like so: - (void) switchToMyDayView { NSLog(@"Show My Day Screen"); if (self.myDayController.view.superview == nil) { if (self.myDayController == nil) { MyDayController *myController = [[MyDayController alloc] initWithNibName:@"MyDay" bundle:nil]; self.myDayController = myController; [myController release]; } [homeScreenController.view removeFromSuperview]; [self.view insertSubview:self.myDayController.view atIndex:0]; } } Which is done on the main navigation screen Now, the MyDayController has a XIB called MyDay.xib which has these items: File's Owner: MyDayController First Responder: UIResponder Split View Controller ---->Navigation Controller ---->Navigation Bar ----> Table View Controller ----> Navigation Item ---->View Controller So, I need some more components here, I need a UITableViewController and a UISplitViewControllerDelegate correct? I was going to just implement these protocols in my MyDayController, is this sort of standard? So, after the code above, I get an error: -[UIViewController _loadViewFromNibNamed:bundle:] loaded the "MyDay" nib but the view outlet was not set. so, how can I fix it using the UISplitViewController? I know that the UISplitViewController has a view property, but I cannot use it/connect it up in IB can I? Thanks a lot Mark

• How to conform to UITabBarControllerDelegate

  - by 4thSpace

  I have a tabbar based application and do the following to get a reference to the application delegate: MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; Which then gives this warning: warning: type 'id <UIApplicationDelegate>' does not conform to the 'UITabBarControllerDelegate' My application delegate header looks like this: #import <UIKit/UIKit.h> @interface MyAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end The only methods in the .m file are applicationDidFinishLaunching and dealloc. What else do I need to conform to the protocol?

• Handling multiple UISwitch controls in a table view without using tag property

  - by Thaurin

  I have a table view controller with multiple UISwitch controls in them. I set the delegate to the table view controller with the same action for all switches. I need to be able to determine what switch was changed, so I create an array of strings that contains the name of each switch. The indexes in the array will be put in the tag property of each UISwitch. However, I'm ready using the tag property for something else, namely to find the right control in the cell in cellForRowAtIndexPath with viewWithTag! (There are several things I need to set within each cell.) So, am I thinking along the right lines here? I feel I'm rather limited in how I find out exactly which UISwitch changed its value, so I can do something useful with it.

• What is the delegate method that is called when an MKPinAnnotationView is touched?

  - by Jake Schwartz

  I have been searching for this all night and I have just so frustrated. When a MKPinAnnotationView is clicked, the name and the subtitle comes up. I also want to center that point on the view. I figured there was some method I had to override because the information that pops up happened without me having to code it. Hopefully this was clear enough for you all. And in the mean time, I feel like there is some hidden guide on this use of MKMaps and other classes. Either that or it is terribly documented because I am having a lot of trouble finding information. Thanks.

• First Tap on customcell of uitableview should expand it and second should contract it.

  - by neha

  Hi all, In my application I have this requirement that first tap on custom cell of uitableview with a label in it should expand it and second should contract it. I'm able to expand and contract cell and expand label inside cell, but not able to contract the label on second tap. I'm using this function - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; if( selected == YES ) { [self expandRow]; } else { [self contractRow]; } height = [lblFeed frame].size.height + 75; } expandRow expands the label and contractRow contracts it. I'm perplexed as for how many rows this function gets called. It doesn't get called only for the cell tapped, it gets called more number of times for single tap on single cell may be for other cells but I'm not getting which rows. This' really urgent. Can anybody please help?

• UISearchDisplayController not working when created in code??

  - by Nick Bedford

  I'm working on a tab bar application and one of the tabs has a UISearchDisplayController hooked up to a UISearchBar. It's all connected up in the NIB and is working. When I tap the search bar, the Scope and Cancel buttons fly in etc, and the search delegate updates the results table correctly. However, I'm trying to implement the same code in the viewDidLoad message instead of the NIB, however when I delete the search display controller from the NIB and uncomment my code to create the same controller in the function, it doesn't work. It's as if there's some fundamental connection not being made so that all my search delegate functionality isn't being called. Here's my working NIB version of the Search Display Controller. It's hooked up to the search bar, the UINavigationController subclass (MASearchController) and the root view of that is hooked up as the searchContentsController. Now this is what you would expect to do in code to create the same, right? What I'm doing is leaving the UISearchBar in the NIB to eliminate one piece of the puzzle at a time in code. // [MASearchController viewDidLoad] UISearchDisplayController *searchController = [[[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:[[self viewControllers] objectAtIndex:0]] autorelease]; [searchController setDelegate:self]; [searchController setSearchResultsDelegate:self]; [searchController setSearchResultsDataSource:self]; I've checked all objects at run time and they all check out. Essentially I've deleted the search display controller from the NIB and then put in the code to create it in the viewDidLoad message. Why would this not work? The search keyboard comes up but none of my search and button animation functionality work???

• AVAudioPlayer making noise when playing multiple sounds at the same time

  - by Rob

  I am having an issue where AVAudioPlayer is introducing noise into playback ONLY when I play multiple sound files at the same time. If I play them each individually, they all sound perfect. But, if I play sound clip B while sound clip A is still playing, the speakers start crackling like there is noise. I have tried both m4a files AND caf files and both make the same noise, so it has to be something with how I am implementing this method or a quirk with AVAudioPlayer. Any insights? code I am using: UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [soundArray objectAtIndex:[touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"m4a"]; AVAudioPlayer * newAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; self.theAudio = newAudio; // automatically retain audio and dealloc old file if new m4a file is loaded [newAudio release]; // release the audio safely theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:0]; [theAudio setVolume: volumeLevel]; [theAudio play];

• Obtaining the tropicity of an image on the iPhone

  - by WhiteTiger

  Hello all I was wondering how it's possible to find out if an image in the iPhone photo library is isotropic or anisotropic. Basically how many millimeters each pixel measures in height and in width. In JPG images the information is hardcoded into the data stream so it's possible to do by simply pointing a const char* to the image file, but I'm not sure I can do that with the data the iPhone image returns. Thank you in advance

• Possible to use Buddypress within an iPhone app?

  - by lostInTransit

  Hi I want to create a community for my venture and also an iphone application for the same. I am thinking of using Buddypress for the community. But is it possible to use buddypress with an iPhone app? I'd like that when user posts a message via the iPhone app, it is also posted on buddypress? Or do I have to write custom scripts for editing the buddypress db according to user actions in the iPhone app? Thanks.

• Avoid hardcoding iPhone screen size with programmatic view creation

  - by miorel

  Hi, I was looking up how to create a view programmatically and found the following example code: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; This works great, except I don't like that it hardcodes the size of the screen. Is there a way to look up the size of the screen? An important point someone brought up is that if the app is running during a phone call then the screen will be slightly smaller because of the green "return to call" bar.
