  • How to detect when UITextField become empty

    - by Jakub
    Hello, I would like to perform a certain action when UITextField becomes empty (user deletes everything one sign after another or uses the clear option). I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

    - by pyt
    Hello, All. I've tried video recording in the background. But had failed. Under normal circumstances, the recording works properly. However, if HOME key down- Home screen or Other Activity is running, recording terminates. In such a situation, I want to record continuously. I want to record whole process! What should I do? thanks. -Michael

  • uniimageview not updating after views tranistion

    - by Fabio Ricci
    Hi I have one main view where I display an image, in the method viewDidLoad: ballRect = CGRectMake(posBallX, 144, 32.0f, 32.0f); theBall = [[UIImageView alloc] initWithFrame:ballRect]; [theBall setImage:[UIImage imageNamed:@"ball.png"]]; [self.view addSubview:theBall]; [laPalla release]; Obviously, the value of posBallX is defined and then update via a custom method call many times in the same class. theBall.frame = CGRectMake(posBallX, 144, 32, 32); Everything works, but when I go to another view with [self presentModalViewController:viewTwo animated:YES]; and come back with [self presentModalViewController:viewOne animated:YES]; the image is displayed correctly after the method viewDidLoad is called (I retrieve the values with NSUserDefaults) but no more in the second method. In the NSLog I can even see the new posBallX updating correctly, but the Image is simply no more shown... The same happens with a Label as well, which should print the value of posBallX. So, things are just not working if I come back to the viewOne from the viewTwo... Any idea??????? Thanks so much!

  • iPhone: Error when using -(id)initWithNibName

    - by Nic Hubbard
    I am trying to use the following code, but I always get an error that I can find little information about: - (id)initWithNibName:@"MyRidesListView" bundle:nil { if ((self = [super initWithNibName:@"MyRidesListView" bundle:nil])) { // Custom initialization } return self; } Error: expected identifier before 'OBJC_STRING' token This seems like a simple method to be calling. This is for a UINavigationController. Ideas?

  • changing sounds when objects meet

    - by blacksheep
    i'd like to change sounds when tapping on an image and drag another image over several others. it is not working properly: the "MoveImage" is not dragable, the tapping is working outside the "TouchImage" and the sounds do not change when tapping on it. (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)))) { [sound_E play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)))) { [sound_F play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)))) { [sound_D play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)))) { [sound_Dis play]; } } (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if (CGRectContainsPoint(myMoveImage.frame, location)){ CGPoint yLocation = CGPointMake(myMoveImage.center.x,location.y); myMoveImage.center = yLocation; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)) { E_NOTE.text = @"E"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)) { F_NOTE.text = @"F"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)) { D_NOTE.text = @"D"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)) { Dis_NOTE.text = @"D#"; } }

Thanks

  • How to make UIImagePickerController works under switch case UIActionSheet

    - by Phy
    -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *tempImage = [info objectForKey:UIImagePickerControllerOriginalImage]; imgview.image = tempImage; [self dismissModalViewControllerAnimated:YES]; [picker release]; } -(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { [self dismissModalViewControllerAnimated:YES]; [picker release]; } -(IBAction) calllib { img1 = [[UIImagePickerController alloc] init]; img1.delegate = self; img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:img1 animated:YES]; } all the codes above works well for taking out photos from the photo library. problem is that when i tried to use it under the UIActionSheet it does not work. i just copy the lines of codes from the -(IBAction) calllib as follow. (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { UIImage *detectface = [Utilities detectFace:imgview.image]; UIImage *grayscale = [Utilities grayscaleImage:imgview.image]; UIImage *avatars = [Utilities avatars:imgview.image]; img1 = [[UIImagePickerController alloc] init]; img1.delegate = self; img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; switch (buttonIndex) { case 0: [self presentModalViewController:img1 animated:YES]; imgview.image = detectface; break; case 1: [self presentModalViewController:img1 animated:YES]; imgview.image = grayscale; break; case 2: [self presentModalViewController:img1 animated:YES]; imgview.image = avatars; break; default: break; } } it does not work. can somebody help me to figure out what is the problem? the switch case works perfectly without the [self presentModalViewController:img1 animated:YES]; ... thanks

  • How can I run an app's source code that I got from the Android source code?

    - by Wesley
    For all of you android devs out there that have the Android simulator running on your comp, you know that there are a few built in apps that are already 'installed' on your phone. I had an idea for an app that would utilize a function that is already being done in the spare parts app. I went on to the android developer site, dug through the source code files, and found the spare parts app, and am now trying to set it up so that running it from eclipse on my machine actually runs the app in the simulator. In other words, I want to be able to make changes to and adjust some of the things in that app for my own needs. But it won't compile, because of a number of different errors. How do I get that source code running on my local machine? Is there some special trick that I just dont know about? I thought that if I could get the source code than the rest would be easy, but it isn't being too easy. Any help here would be appreciated!!

  • Out-Of-Memory while doing Core Data migration

    - by Kamchatka
    Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?

  • UIImageView subclass with CGRectIntersectsRect - help!

    - by Flafla2
    The title of this question should be pretty self explanatory. I am making an app that involves multiple UIImageViews that serve the same purpose. They are merely different sizes. Anyway, I decided that the best solution was to make UIImageView subclasses, link the subcalsses in IB, and work from there. My code should explain this better - #define kPausedStatePaused 1 #define kPausedStatePlay 2 #import "Game.h" #import "ScoreSystem.h" @interface Doctor : UIImageView { } @end @interface Ground : UIImageView { } @end @interface Wall : UIImageView { } @end @interface Electric_Wire : UIImageView { } @end @implementation Game /* // The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } */ /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ - (IBAction)pause { UIAlertView *pause = [[UIAlertView alloc] initWithTitle:@"Pause" message:nil delegate:self cancelButtonTitle:@"Quit" otherButtonTitles:@"Play", nil]; [pause show]; [pause release]; pauseint = kPausedStatePaused; } - (void)viewDidAppear { pauseint = kPausedStatePlay; } - (void)loop { Doctor *doctorview; Ground *groundview; if (CGRectIntersectsRect(doctorview, groundview)) { } } - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if ([alertView.title isEqual:@"Pause"]) { if(buttonIndex == 0) [self dismissModalViewControllerAnimated:YES]; pauseint = kPausedStatePlay; } } // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end Unsurprisingly, Xcode gave me an "incompatible type for CGRectIntersectsRect" error.

  • IBOutlet instances are (null) after loading from NIB

    - by Zach
    I am working on an iPhone app and am getting (null) references to IBOutlet fields in my controller. I have a UIViewController subclass that is set as the File's Owner in my XIB. I have a set of UI elements that are wired into the controller. After loading from NIB and attempting to set properties on those UI elements, I find that they are (null). To clarify, some code: ExpandSearchPageController.h: @interface ExpandSearchPageController : UIViewController { IBOutlet UITextView * completeMessageView; } -(void)checkTextField; @property (nonatomic, retain) IBOutlet UITextView * completeMessageView; ExpandSearchPageController.m: @implementation ExpandSearchPageController @synthesize completeMessageView; -(void)checkTextField { NSLog(@"text field: %@",completeMessageView); } ExpandSearchPageController is set as the File's Owner for ExpandSearchPage.xib. ExpandSearchPage.xib's UITextView is wired to the completeMessageView. When I call ExpandSearchPageController * searchExpanderPage = [[ExpandSearchPageController alloc] initWithNibName:@"ExpandSearchPage" bundle:[NSBundle mainBundle]]; [searchExpanderPage checkTextField]; the result is "text field: (null)" Sorry if this is a total newb question, but I guess I'm still a newb at iPhone programming! Thanks in advance!

    I have a Core Data based application that stores hierarchal data displayed using a series of UITableViews. To illustrate my app functionality to the user I would like to pre-populate my database/app with some dummy values. This data would be available upon installation on the user's iPhone/iPod Touch. What is the best way to achieve this?

  • Assign click event to addon icon on navigation bar

    - by Charsee
    We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

  • Redirecting input to another view

    - by Jon
    My application is working fine on the normal iPad display, but I also need to output to VGA out. When I do this, I need to add the view to the external screen's window which seems to mean that I can't use it to accept input from the iPad screen. I want to redirect input from the iPad's window to the window displaying on the external screen. As far as I can tell there's no standard method of doing this. I've tried overriding hitTest on the iPad's window view to send it to the window on the external display, but the coordinates seem to get messed up in the process which makes it nigh unusable. I've also tried subclassing the iPad's UIWindow and catching events in sendEvent, then trying to send them to the external window, but this doesn't seem to work at all. Any help would be appreciated, I'm happy to post any code you would like to see. Thanks, Jon
