  • How to intercept touches events on a MKMapView or UIWebView objects?

    - by Martin
    Hello, I'm not sure what i'm doing wrong but I try to catch touches on a MKMapView object. I subclassed it by creating the following class : #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewWithTouches : MKMapView { } - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event; @end And the implementation : #import "MapViewWithTouches.h" @implementation MapViewWithTouches - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event { NSLog(@"hello"); //[super touchesBegan:touches withEvent:event]; } @end But it looks like when I use this class, I see nothing on the Console : MapViewWithTouches *mapView = [[MapViewWithTouches alloc] initWithFrame:self.view.frame]; [self.view insertSubview:mapView atIndex:0]; Any idea what I'm doing wrong? Heelp! :) Thanks a lot! Martin

  • Changing UIImageView animation speed

    - by Nikolas Stephan
    I am using the UIImageView to animate a bunch of images. I know that I can change the speed by altering animationDuration, but that doesn't seem to take effect until the animation is restarted. My problem is that beside not really wanting to have to restart the animation as this limits me to only being able to change the speed once per cycle, there also doesn't seem to be a way to find out what frame is currently being shown and I would therefore have to rely on a timer to "guess" which one it is. So my question is whether there is a way to change the speed without restarting the animation and if not is there some way I could avoid the aforementioned problem? I'm not too keen to write my own animation class, but may end up having to if there isn't a nicer solution.

  • UIScrollView won't autorotate

    - by clozach
    My app design requires the same scrolling functionality found in the iPhone's native Photos app when browsing photos in full screen. Specifically: Each view snaps into place as the view is swiped Scrolling happens in only one direction Rotating the iPhone rotates the entire scrolling region as well such that the frame of each subview (photos, in Apple's case) rotates in-place and paging is still in the same direction (left-to-right) I started to use Apple's sample PageControl code as a launching point, and everything was going swimmingly until I attempted adding autorotation to the code. My sense from the docs was that all I had to do to get autorotation working was to add this to the sample code's MyViewController.m - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } While that does seem to cause the subviews' backgrounds to rotate, the UILabels and the enclosing UIScrollView stay fixed so that, from a user perspective, paging through the views now requires up/down flicking instead of left/right.

  • Crash when trying to get NSManagedObject from NSFetchedResultsController after 25 objects?

    - by Jeremy
    Hey everyone, I'm relatively new to Core Data on iOS, but I think I've been getting better with it. I've been experiencing a bizarre crash, however, in one of my applications and have not been able to figure it out. I have approximately 40 objects in Core Data, presented in a UITableView. When tapping on a cell, a UIActionSheet appears, presenting the user with a UIActionSheet with options related to the cell that was selected. So that I can reference the selected object, I declare an NSIndexPath in my header called "lastSelection" and do the following when the UIActionSheet is presented: // Each cell has a tag based on its row number (i.e. first row has tag 0) lastSelection = [NSIndexPath indexPathForRow:[sender tag] inSection:0]; NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; BOOL onDuty = [[managedObject valueForKey:@"onDuty"] boolValue]; UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Status" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; if(onDuty) { [actionSheet addButtonWithTitle:@"Off Duty"]; } else { [actionSheet addButtonWithTitle:@"On Duty"]; } actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque; // Override the typical UIActionSheet behavior by presenting it overlapping the sender's frame. This makes it more clear which cell is selected. CGRect senderFrame = [sender frame]; CGPoint point = CGPointMake(senderFrame.origin.x + (senderFrame.size.width / 2), senderFrame.origin.y + (senderFrame.size.height / 2)); CGRect popoverRect = CGRectMake(point.x, point.y, 1, 1); [actionSheet showFromRect:popoverRect inView:[sender superview] animated:NO]; [actionSheet release]; When the UIActionSheet is dismissed with a button, the following code is called: - (void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex { // Set status based on UIActionSheet button pressed if(buttonIndex == -1) { return; } NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; if([actionSheet.title isEqualToString:@"Status"]) { if([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"On Duty"]) { [managedObject setValue:[NSNumber numberWithBool:YES] forKey:@"onDuty"]; [managedObject setValue:@"onDuty" forKey:@"status"]; } else { [managedObject setValue:[NSNumber numberWithBool:NO] forKey:@"onDuty"]; [managedObject setValue:@"offDuty" forKey:@"status"]; } } NSError *error; [self.managedObjectContext save:&error]; [tableView reloadData]; } This might not be the most efficient code (sorry, I'm new!), but it does work. That is, for the first 25 items in the list. Selecting the 26th item or beyond, the UIActionSheet will appear, but if it is dismissed with a button, I get a variety of errors, including any one of the following: [__NSCFArray section]: unrecognized selector sent to instance 0x4c6bf90 Program received signal: “EXC_BAD_ACCESS” [_NSObjectID_48_0 section]: unrecognized selector sent to instance 0x4c54710 [__NSArrayM section]: unrecognized selector sent to instance 0x4c619a0 [NSComparisonPredicate section]: unrecognized selector sent to instance 0x6088790 [NSKeyPathExpression section]: unrecognized selector sent to instance 0x4c18950 If I comment out NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:lastSelection]; it doesn't crash anymore, so I believe it has something do do with that. Can anyone offer any insight? Please let me know if I need to include any other information. Thanks! EDIT: Interestingly, my fetchedResultsController code returns a different object every time. Is this expected, or could this be a cause of my issue? The code looks like this: - (NSFetchedResultsController *)fetchedResultsController { /* Set up the fetched results controller. */ // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. NSEntityDescription *entity = [NSEntityDescription entityForName:@"Employee" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; // Set the batch size to a suitable number. [fetchRequest setFetchBatchSize:80]; // Edit the sort key as appropriate. NSString *sortKey; BOOL ascending; if(sortControl.selectedSegmentIndex == 0) { sortKey = @"startTime"; ascending = YES; } else if(sortControl.selectedSegmentIndex == 1) { sortKey = @"name"; ascending = YES; } else { sortKey = @"onDuty"; ascending = NO; } NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:sortKey ascending:ascending]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Edit the section name key path and cache name if appropriate. NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; if (![fetchedResultsController_ performFetch:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. */ //NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return fetchedResultsController_; } This happens when I set a breakpoint: (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x61567c0> (gdb) po [self fetchedResultsController] <NSFetchedResultsController: 0x4c83630>

  • setSearchDisplayController considered private-API?

    - by Adun
    Hi, I recently submitted an app for app review but I got rejected because of the use of a private API. I'm still a bit new to iPhone developing so I was wondering if someone could help me understand how this part was rejected: UISearchBar *searchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 0)] autorelease]; searchBar.showsCancelButton = NO; searchBar.placeholder = @"Search Exhibitors"; [searchBar sizeToFit]; [self.tableView setTableHeaderView:searchBar]; UISearchDisplayController *searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self]; [self performSelector:@selector(setSearchDisplayController:) withObject:searchDisplayController]; [searchDisplayController setDelegate:self]; [searchDisplayController setSearchResultsDataSource:self]; [searchDisplayController setSearchResultsDelegate:self]; [searchDisplayController release]; The part that they mentioned was the "setSearchDisplayController". I based the searching of a UITableView on the example given here. So can anyone explain why this is considered a private API?

  • How to override a method for a MovieClip Symbol in Flash CS3

    - by php html
    I'm using flash to draw objects, then I export them and use them from flex, and I'm a beginner in flash. I'm trying to do the override a method from the MovieClip I created. The method I'm trying to override is stop() method. I didn't write a single line of code, my movie clip is created using entirely the flash interface. I figured out how to add actions to the movie clip when a frame is reached but I'm stucked now when I'm trying to override a MovieClip method.

  • Error when trying to create a faceted plot in ggplot2

  • glTexImage2D behavior on iPhone and other OpenGL ES platforms

    - by spurserh
    Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. I suspect that the use of glTexImage2D with one or two frames of look-ahead, that is, using several textures so that the glTexImage2D call can be initiated a frame or two ahead, will allow for sufficient parallelism to play in real time if the system is capable of it at all. Is my assumption true that the driver will handle the actual data transfer to the hardware asynchronously after glTexImage2D returns, assuming I don't try to use the texture or call glFinish/glFlush? Is there a better way to do this with OpenGL ES? Thank you very much, Sean

  • How to set a Transparent Background of JPanel

    - by Imran
    Hi, I need to know if a JPanel`s bacground can be set to Transparent? My frame is has two Jpanels Image Panel and Feature Panel, Feature Panel is overlapping Image Panel, the Image Panel is working as a background and it is loading image from a remote Url, now I want to draw shaps on Feature Panel , but now Image Panel cannot be seen due to Feature Panel's background color. I need to make Feature Panel background transparent while still drawing its shapes and i want Image Panel to be visible since it is doing tiling and cache function of images. I need to seperate the image drawing and shape drawing thats why I`m using two jPanels! is there anyway the overlapping Jpanel have a transparent background? thanks

  • Get signal names from numbers in Python

    - by Brian M. Hunt
    Is there a way to map a signal number (e.g. signal.SIGINT) to its respective name (i.e. "SIGINT")? I'd like to be able to print the name of a signal in the log when I receive it, however I cannot find a map from signal numbers to names in Python, i.e. import signal def signal_handler(signum, frame): logging.debug("Received signal (%s)" % sig_names[signum]) signal.signal(signal.SIGINT, signal_handler) For some dictionary sig_names, so when the process receives SIGINT it prints: Received signal (SIGINT) Thank you.

  • UIButton not firing selector if I draw it using CALayer

    - by Horatiu Paraschiv
    Hi everybody I create this button like this: _myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; DLBadgeLayerDelegate *layerDelegate = [[DLBadgeLayerDelegate alloc] init]; _myButton.frame = CGRectMake(0.0 , 0.0, 100.0, 100.0); [_myButton addTarget:self action:@selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; _myButton.layer.backgroundColor = [[UIColor redColor] CGColor]; _myButton.center = CGPointMake(10.0, 10.0); [self addSubview:_myButton]; [_myButton release]; The button appears on the screen but if I tap on it nothing happens. If I just create a Rounded rect button instead with no custom drawing on its layer or if I just leave the layer line of code out all works well. Do you have any Idea why do I get this behaviour as I would like to do some custom drawing in the button's layer?

  • Move a legend in ggplot2

    - by Dan Goldstein
    I'm trying to create a ggplot2 plot with the legend beneath the plot. The ggplot2 book says on p 112 "The position and justification of legends are controlled by the theme setting legend.position, and the value can be right, left, top, bottom, none (no legend), or a numeric position". The following code works (since "right" it is the default), and it also works with "none" as the legend position, but "left", "top", "bottom", all fail with "Error in grid.Call.graphics("L_setviewport", pvp, TRUE) : Non-finite location and/or size for viewport" library(ggplot2) (myDat <- data.frame(cbind(VarX=10:1, VarY=runif(10)), Descrip=sample(LETTERS[1:3], 10, replace=TRUE))) qplot(VarX,VarY, data=myDat, shape=Descrip) + opts(legend.position="right") What am I doing wrong? Re-positioning a legend must be incredibly common, so I figure it's me.

  • Back button loop with IFRAMES

    - by Tim Jackson
    In my (school) website we use Iframes to display class blogs (on blogger). This works well EXCEPT if the user then clicks on (say) a photo inside the iframe. Blogger (in this case) then displays the photo in the whole browser window and the back button loops; that is if the back button is hit, the browser (IE, FF, Chrome) stays on the same page. The only way out is for the user to jump back two pages (which many of our users don't know how to do). I've read a lot of posts on back buttons and iframes and there doesn't appear to be a simple solution. Bear in mind that I don't have control over the iframe content (so no embedded back buttons in the frame are possible). Ideas anyone?

  • Repairing malformatted html attributes using c#

    - by jhoefnagels
    I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>

  • How to add a view on top of a UIPopoverController

    - by Noah Witherspoon
    I've got an iPad app with a “drawer” table displayed in a popover. The user can tap-and-hold on an item in the drawer to drag that item out of it and into my main view. That part works fine; unfortunately, the view being dragged appears under the popover, and is too small to be visible until it's dragged out from underneath it. If I add the view as a subview of the view controller in the popover, it gets clipped by the popover's frame, and as I can't access the UIPopoverController's view, I can't disable its layer's masksToBounds—and that probably wouldn't be a great idea anyway. I suspect that I could use an additional UIWindow with a high windowLevel value to force the dragged view to appear on top of the popover, but this seems like overkill. Is there a better solution?

  • ScrollPane has type of "movieclip" in attached movieclip

I've tried exporting it for ActionScript, exporting the wrapper movieclip "ScrollPaneWrapper" and "Export in Frame 1" and all combinations of these options. What's more weird is that I have another Flash project in which I can access the ScrollPane as expected and I can't tell any differences between the two projects. Casting the spw.sp to ScrollPane results in null.

  • LaTeX beamer free-flowing two column?

    - by anon
    So in standard LaTeX, there is \twocolumn, where I can just type text, and it'll go down the left side of the page, then continue at the top of the right side of the page. Now, I know that inside of a Beamer frame, I can manually create two columns, of various width, with text in them -- however, is there a way to have the text freely flow from one column to the next? [I.e. I want to say "this text goes in these two columns; and have beamer figure out which goes into which column]. Thanks!

  • Android: 2D. OpenGl or android.graphics?

    - by DroidIn.net
    I'm working with my friend on our first Android game. Basic idea is that every frame the whole surface is redrawn (1 large bitmap) which then sprinkled all over with large number of particles which produces effect of soapy bubbles where there's a pool of about 20 bitmaps which randomly gets picked to produce illusion that all bubbles (between 200 - 300) are all different. The math engine is in C (JNI) and currently all drawing is done using android.graphics package very similar (since that was the example I was using) to Lunar Lander. It works but animation is somewhat jerky and I can feel by temperature of my phone that it is very busy. Will we benefit from switching to OpenGL? And as a bonus question: what would be a good way to optimize the drawing mechanism (Lunar Lander like) we have now?

  • UISplitViewCOntroller + TabBarCOntroller + iPad

    - by tek3
    Hi all, I am developing a tab-based iPad application in which corresponding to each tab, I have to show an UISplitViewController . I have done this by adding two navigation controllers to my tabBarController and assigning a subclass of UISplitViewController as RootViewController of both navigationController. And also I have to show both viewControllers(Master and Detail) in both modes(Potrait and Landscape). For this I have constructed a subclass of UISplitViewController in which i am overriding willAnimateRotationToInterfaceOrientation method and setting the frame of both ViewControllers as demonstrated in this link. However i am not able to set both viewControllers correctly.If my app starts in Landscape mode everything displays fine but if i open it in Potrait mode then the orientation of both ViewControllers changes. Sometimes the MasterView occupies the entire screen or sometimes both ViewControllers appear leaving a black line between them and the navigationBar. I have been banging my head over this problem since two days without any success. kindly help..
