  • UISearchbar clearButton forces the keyboard to appear

    - by DASKAjA
    I have a UISearchBar which acts as a live filter for a table view. When the keyboard is dismissed via endEditing:, the query text and the gray circular "clear" button remain. From here, if I tap the gray "clear" button the keyboard reappears as the text is cleared. How do I prevent this? If the keyboard is not currently open I want that button to clear the text without reopening the keyboard. There is a protocol method that gets called when I tap the clear button. But sending the UISearchBar a resignFirstResponder message doesn't have any effect on the keyboard.

  • Issue with CAAnimation and CALayer Transforms

    - by Brian
    I have a CALayer that I want to animate across the screen. I have created two methods: one slide open the layer and one to slide close. These both work by assigning a property to the layer's transform property. Now I want to use a CAKeyFrameAnimation to slide open the layer. I got this working so the layer slides open, but now I can't slide the layer close using my old method. I am trying to figure out why this is. Any help would be great. Code: - (id)init { if( self = [super init] ) { bIsOpen = NO; closeTransform = self.transform; openTransform = CATransform3DMakeTranslation(-235.0, 0.0, 0.0); } return self; } - (void)closeMenu { if( bIsOpen ) { self.transform = closeTransform; bIsOpen = !bIsOpen; } } - (void)openMenu { if( !bIsOpen ) { CAKeyframeAnimation *closeAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform"]; closeAnimation.duration = 1.0; closeAnimation.removedOnCompletion = NO; closeAnimation.fillMode = kCAFillModeForwards; closeAnimation.values = [NSArray arrayWithObjects:[NSValue valueWithCATransform3D:closeTransform],[NSValue valueWithCATransform3D:openTransform],nil]; closeAnimation.timingFunctions = [NSArray arrayWithObject:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]]; [self addAnimation:closeAnimation forKey:@"transform"]; bIsOpen = !bIsOpen; } }

  • Problem with migrating from Texture2D to CCTexture2D (Setting CCSprite texture)

    - by marie
    My problem is that whenever I change the texture of a sprite, the new texture will retain the size of the original sprite's texture. I have this code: mySprite = [CCSprite spriteWithFile:@"mySprite.png"]]; ... // change current stage here CCTexture2D *newTexture=[[[CCTexture2D alloc]initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"stage number %d.png",currentStageNumber]]]autorelease]; [mySprite setTexture:newTexture]; The new sprite is stretched or compressed depending on the size of the original sprite. If the original sprite is larger, the new texture is stretched. I didn't have this problem when I was using cocos2d v0.8 What am I doing wrong?

    I got the following code: - (id)init { if (self = [super init]) { UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback; AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory); UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride); [[AVAudioSession sharedInstance] setDelegate:self]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; [[AVAudioSession sharedInstance] setActive:YES error:nil]; } return self; } But somehow the sound does not want to come out of the speakers, can someone see what I am doing wrong? The code I use for playing is: AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFilePathURL error:nil]; [player prepareToPlay]; [player setVolume:1.0]; [player play];

  • Passing Variables between views / view controllers

    - by Dan
    Hi I'm new to ObjectiveC / IPhoneSDK and I'm informally trying to study it on my own. What I'm basically trying to do is from one view there are 12 zodiac signs. When a user clicks one, it proceeds to the second view (with animation) and loads the name of the zodiac sign it clicked in a UILabel, that's it. Here are my codes: Lovescopes = 1st page Horoscopes = 2nd page Lovescopes4AppDelegate.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @class Lovescopes4ViewController; @interface Lovescopes4AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; Lovescopes4ViewController *viewController; HoroscopesViewController *horoscopesViewController; } -(void)loadHoroscope; -(void)loadMainPage; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet Lovescopes4ViewController *viewController; @property (nonatomic, retain) HoroscopesViewController *horoscopesViewController; @end Lovescopes4AppDelegate.m #import "Lovescopes4AppDelegate.h" #import "Lovescopes4ViewController.h" @implementation Lovescopes4AppDelegate @synthesize window; @synthesize viewController; @synthesize horoscopesViewController; -(void)loadHoroscope { HoroscopesViewController *aHoroscopeViewController = [[HoroscopesViewController alloc] initWithNibName:@"HoroscopesViewController" bundle:nil]; [self setHoroscopesViewController:aHoroscopeViewController]; [aHoroscopeViewController release]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES]; [viewController.view removeFromSuperview]; [self.window addSubview:[horoscopesViewController view]]; [UIView commitAnimations]; } -(void)loadMainPage { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:NO]; [horoscopesViewController.view removeFromSuperview]; [self.window addSubview:[viewController view]]; [UIView commitAnimations]; [horoscopesViewController release]; horoscopesViewController = nil; } - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end Lovescopes4ViewController.h #import <UIKit/UIKit.h> #import "HoroscopesViewController.h" @interface Lovescopes4ViewController : UIViewController { HoroscopesViewController *hvc; } -(IBAction)loadAries; @property (nonatomic, retain) HoroscopesViewController *hvc; @end Lovescope4ViewController.m #import "Lovescopes4ViewController.h" #import "Lovescopes4AppDelegate.h" @implementation Lovescopes4ViewController @synthesize hvc; -(IBAction)loadAries { NSString *selected =@"Aries"; [hvc loadZodiac:selected]; Lovescopes4AppDelegate *mainDelegate = (Lovescopes4AppDelegate *) [[UIApplication sharedApplication] delegate]; [mainDelegate loadHoroscope]; } HoroscopesViewController.h #import <UIKit/UIKit.h> @interface HoroscopesViewController : UIViewController { IBOutlet UILabel *zodiacLabel; } -(void)loadZodiac:(id)zodiacSign; -(IBAction)back; @property (nonatomic, retain) IBOutlet UILabel *zodiacLabel; @end HoroscopesViewController.m #import "HoroscopesViewController.h" #import "Lovescopes4AppDelegate.h" @implementation HoroscopesViewController @synthesize zodiacLabel; /* // The designated initializer.

  • When to call release on NSURLConnection delegate?

    - by Kieran H
    Hi, When passing a delegate to the a NSUrlConnection object like so: [[NSURLConnection alloc] initWithRequest:request delegate:handler]; when should you call release on the delegate? Should it be in connectionDidFinishLoading? If so, I keep getting exec_bad_access. I'm seeing that my delegates are leaking through instruments. Thanks

  • UISearchDisplayController - how to display search result with only by scope button selected but empt

    - by billibala
    The UISearchDisplayController is very handy and implementing search is pretty straightforward. However, I bump into problem when, in my app, I want to display search result with empty search string but selected scope button. It seems like it's a must to enter some search string in order to get the search result table being initialized and displayed. Is there any ways to display search result immediately after user has picked a scope but not entered search word yet? Thanks Bill

  • applicationWillTerminate Appears to be Inconsistent

    - by Lauren Quantrell
    This one has me batty. In applicationWillTerminate I am doing two things: saving some settings to the app settings plist file and updating any changed data to the SQLite database referenced in the managedObjectContext. Problem is it works sometimes and not others. Same issue in the simulator and on the device. If I hit the home button while the app is running, I can only sometimes get the data to store in the plist and into the CoreData store. It seems that it's both works or neither works, and it makes no difference if I switch the execution order (saveState, managedObjectContext or managedObjectContext, saveState). I can't figure out how this can happen. Any help is greatly appreciated. lq AppDelegate.m @synthesize rootViewController; - (void)applicationWillTerminate:(UIApplication *)application { [rootViewController saveState]; NSError *error; if (managedObjectContext != nil) { if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) { // Handle error exit(-1); // Fail } } } RootViewController.m - (void)saveState { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:self.someInteger forKey:kSomeNumber]; [userDefaults setObject:self.someArray forKey:kSomeArray]; }

  • MKReverseGeocoder delegate location?

    - by fuzzygoat
    I have a quick question regarding memory management that I am not quite sure about. I currently have a locationManager delegate that calls locationManager:didUpdateToLocation:fromLocation when it resolves the device location. My question is I am looking at adding ReverseGeoCoding after I have obtained the [newLocation coordinate] but am unsure about doing the alloc here, as each time locationManager:didUpdateToLocation:fromLocation gets called I will be alloc-ing a new MKReverseGeoCoder? // LOCATION -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // GeoCoding: MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:[newLocation coordinate]]; [geoCoder setDelegate:self]; [geoCoder start]; [self foundLocation]; } Can anyone point me in the right direction with regards to this? I did try doing the alloc in application:didFinishLaunchingWithOptions: but then realised I did not have access to [newLocation coordinate]. many thanks gary

  • UIDatePicker - Problem Localizing

    - by Smorpheus
    Hello, I've created a UIDatePicker in my app and I also have support for several languages. My UIDatePicker is created in Interface Builder, and I have created a seperate localization XIB so I can customize my UIDatePicker. Setting the "Locale" option in IB appears to do nothing. Attempting to change my DatePicker programatically with Locale and NSCalender also do nothing via the following code: NSLocale * locale = [[NSLocale alloc] initWithLocaleIdentifier:@"es_ES"]; datePicker.locale = locale; datePicker.calender = [locale objectForKey:NSLocaleCalender]; This results in an english picker. Here's the really weird thing though. The word for "Today" is translated. As seen in the attached screenshot. (OK I'm not allowed to post images. But imagine a Date & Time picker with "May" in English and "Today" written "Ajourd'hui". Based on what I've read, adding the UIDatePicker programatically doesn't seem to help much.

  • Sorting by dates (including nil) with NSFetchedResultsController

    - by glorifiedHacker
    In my NSFetchedResultsController, I set a sortDescriptor that sorts based on the date property of my managed objects. The problem that I have encountered (along with several others according to Google) is that nil values are sorted at the earliest end rather than the latest end of the date spectrum. I want my list to be sorted earliest, earlier, now, later, latest, nil. As I understand it, this sorting is done at the database level in SQLite and so I cannot construct my own compare: method to provide the sorting I want. I don't want to manually sort in memory, because I would have to give up all of the benefits of NSFetchedResultsController. I can't do compound sorting because the sectionNameKeyPaths are tightly coupled to the date ranges. I could write a routine that redirects indexPath requests so that section 0 in the results controller gets mapped to the last section of the tableView, but I fear that would add a lot of overhead, severely increase the complexity of my code, and be very, very error-prone. The latest idea that I am considering is to map all nil dates to the furthest future date that NSDate supports. My left brain hates this idea, as it feels more like a hack. It will also take a bit of work to implement, since checking for nil factors heavily into how I process dates in my app. I don't want to go this route without first checking for better options. Can anyone think of a better way to get around this problem?

  • Detecting taps on a UIWebView

    - by dubbeat
    Hi, I'm trying to find a way to detect a double tap on a UIWebview. I want to use this action to close it. I however can't find and methods in the documentation for UIWebview taps. Whats the best to add taps to a uiwebview? I tried a tutorial here http://mithin.in/2009/08/26/detecting-taps-and-events-on-uiwebview-the-right-way/ But I don't know how to change my UIWindow to a tap detecting window. Does the above link seem like the best approach or could you suggest another way to remove my WebView?

  • UIWebView memory management

    - by wolfrevo
    Hello, I have a problem with memory management. I am developing an application that makes heavy use of UIWebView. This app generates dynamically lots of UIWebViews while loading content from my server. Some of these UIWebViews are quite large and have a lot of pictures. If I use instruments to detect leaks, I do not detect any. However, lots of objects are allocated and I suspect that has to do with the UIWebViews. When the webviews release because no longer needed, it appears that not all memory is released. I mean, after a request to my server the app creates an UITableView and many webviews (instruments say about 8Mb). When user tap back, all of them are released but memory usage only decrements about 2-3 Mb, and after 5-10 minutes using the app it crashes. Am I missing something? Anyone know what could be happening? Thank you!
