  • My block is not retaining some of its objects

    - by Drew Crawford
    From the Blocks documentation: In a reference-counted environment, by default when you reference an Objective-C object within a block, it is retained. This is true even if you simply reference an instance variable of the object. I am trying to implement a completion handler pattern, where a block is given to an object before the work is performed and the block is executed by the receiver after the work is performed. Since I am being a good memory citizen, the block should own the objects it references in the completion handler and then they will be released when the block goes out of scope. I know enough to know that I must copy the block to move it to the heap since the block will survive the stack scope in which it was declared. However, one of my objects is getting deallocated unexpectedly. After some playing around, it appears that certain objects are not retained when the block is copied to the heap, while other objects are. I am not sure what I am doing wrong. Here's the smallest test case I can produce: typedef void (^ActionBlock)(UIView*); In the scope of some method: NSObject *o = [[[NSObject alloc] init] autorelease]; mailViewController = [[[MFMailComposeViewController alloc] init] autorelease]; NSLog(@"o's retain count is %d",[o retainCount]); NSLog(@"mailViewController's retain count is %d",[mailViewController retainCount]); ActionBlock myBlock = ^(UIView *view) { [mailViewController setCcRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]]; [o class]; }; NSLog(@"mailViewController's retain count after the block is %d",[mailViewController retainCount]); NSLog(@"o's retain count after the block is %d",[o retainCount]); Block_copy(myBlock); NSLog(@"o's retain count after the copy is %d",[o retainCount]); NSLog(@"mailViewController's retain count after the copy is %d",[mailViewController retainCount]); I expect both objects to be retained by the block at some point, and I certainly expect their retain counts to be identical. Instead, I get this output: o's retain count is 1 mailViewController's retain count is 1 mailViewController's retain count after the block is 1 o's retain count after the block is 1 o's retain count after the copy is 2 mailViewController's retain count after the copy is 1 o (subclass of NSObject) is getting retained properly and will not go out of scope. However mailViewController is not retained and will be deallocated before the block is run, causing a crash.

  • View controller is drawing under my navigation bar after popping ttthumbsviewcontroller

    - by scootklein
    I'm implementing the TTThumbsViewController from the Three20 project and things are finally starting to take shape. I push the TTThumbsViewController from the current view controller by just pushing it onto the current stack and animate the transition (common navigation controller push). My problem is that when I pop the TThumbsViewController view controller, the navigation controller is stuck in a mode where its view controllers are drawn UNDER the navigation bar (which is now translucent). Start Push Pop

  • Casting and getting values from date picker and time picker in android

    - by Rahul Varma
    Hi , I have a date picker and a time picker in my app. Can anyone tell me how to get the values of the date and time that are selected??? What i mean to say is, for EditText we can declare as final EditText Name = (EditText) this.findViewById(R.id.nametext); and we can cast the data of it by using Name.getText().toString(). So similarly how can we get the values of date picker and time picker to a string???

  • touchesEnded not being called??? or randomly being called

    - by Rob
    If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Update It has something to do with touchesEnded not being called until the very LAST touch has ended (it doesn't care if you already had 5 other touches end before you finally let go of the last one... it calls them all to end once the very last touch ends) - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }

  • 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.

  • View controllers inside tab bar controller not auto-resizing on rotation

    - by Padawan
    (Correction: the view controllers are not auto-resizing instead of not auto-rotating.) In an iPad app, I have five regular view controllers (not navigation controllers or anything like that) inside a tab bar controller. The tab bar controller is just a plain UITabBarController declared in the app delegate. All the view controllers return YES in the shouldAutorotateToInterfaceOrientation method. On both the simulator and device, on rotation, the tab bar and the current view controller rotate but the currently selected view controller (call it A) does not resize properly. It keeps its portrait width and height (but it is rotated). If I switch to another view controller B and then back to A (without rotating the device again), A appears correctly resized. This happens with any of the five view controllers Why doesn't the currently selected view controller resize immediately on rotation and how do I fix it? Thanks.

  • NSAlert doesn't work

    - by Marco
    Hello i have implemented the following NSAlert: NSString *title = [NSString stringWithFormat:@"Keine Internetverbindung"]; NSString *alertMessage = [NSString stringWithFormat:@"Es konnte keine Verbindung zu www.sip.de aufgebaut werden!"]; NSString *ok = [NSString stringWithFormat:@"Ok"]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:alertMessage delegate:self cancelButtonTitle:ok otherButtonTitles:nil]; [alert show]; [alert release]; and this is the delegate method to close the app: - (void)alertView:(UIAlertView *)alertView didDisMissWithButtonIndex:(NSInteger)buttonIndex{ exit(3); } But why the programm doesn't go into the method, what is my mistake? greetings Marco

  • 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

  • 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.

  • UIRotationGestureRecognizer minimum rotation value

    - by dc
    Is it possible to set a minimum rotation value necessary for a UIRotationGestureRecognizer to transition into UIGestureRecognizerStateRecognized? I'm using multiple recognizers, and my UIRotationGestureRecognizer keeps getting called with a very small rotation (Between 1 and 15 degrees either direction) rather than my UIPinchGestureRecognizer. What I'd like to do is only have the rotation be called if the rotation is within a certain range, otherwise cancel it and let the pinch be called.

  • Mapkit: Only show annotations in current view

    - by Nic Hubbard
    Instead of loading all annotations that are in my array, I would only like to load the annotations that the user could currently see cased on how far they are zoomed in on the map. So, if the user pans to a place where there are annotations, those would be added, and if they pan away, those would be removed. I assume this would help with memory. Does anyone know how to do something like this? And, is it worth it, or needed?

  • Why doesn't genstrings convert NSLocalizedStringFromTable entries to table.strings?

    - by juan tendero
    In my source code I have some lines like NSLocalizedStringFromTable(@"Info", @"en", @"Title of this view"). When I subsequently call genstrings -o en.lproj ./Classes/*.m I would not get the expected file en.strings but Localized.strings, although I've read in the genstrings-manpage that it would generate a table.strings file from NSLocalizedStringFromTable(a, table, c) function. Am I wrong? How would I create a table.strings file then?

  • 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?

  • Allowing user to select a UIPickerView row by tapping.

    - by camilo
    Hi. I'm trying to use a UIPicker View with a behavior somehow different of what's usually seen in iPhone code examples. What I want to do is to allow users to scroll through the picker contents, but not to select a picker's row automatically (using the "didSelectRow" method from picker's delegate). Instead, I want to allow the user to touch the center row of the picker, which gets highlighted, and becomes the selection. Is there any way to achieve this? Thanks in advance.

  • Adding a UIBarButtonItem to a programattically allocated UINavigationBar

    - by iamdadude
    I have a cameraoverlayview that allocates a UINavigationBar to the top of the screen like this - CGRect navbarFrame = CGRectMake(0, 0, 320, 44); navigationBar = [[UINavigationBar alloc] initWithFrame:navbarFrame]; navigationBar.delegate = self; Now I want to add a UIBarButtonItem as the left button to the navigation bar, but the standard navigationbar.leftitem doesn't work. So I tried doing this - closebutton = [[UIBarButtonItem alloc] initWithTitle:closebuttontext style:UIBarButtonItemStylePlain target:self action:@selector(close)]; navigationBar.topItem.leftBarButtonItem = closebutton; But it doesn't work either. Can anyone point me in the right direction? As far as the navigation bar loading up correctly in the cameraoverlayview, it works 100%.
