  • How to segue modal without losing tab bar controller

    - by Arian
    Okay, so I want to be able to have a TabBar Controller with two Tabs (like the template in Xcode), but inside the Second tab, I want to have a button that takes the view to a Third View Controller. I want the Third View Controller to have a back button to the Second Tab, I don't want the Third View to retain the TabBar, but when I go back to the Second Tab I want the TabBar to return. So this is what I actually did, and it doesn't work. I put a button in 2nd view and 3rd view, and I control clicked and dragged to the respective views, and clicked modal. Everything works, except when I go back to the 2nd view I lose the tab bar. Pictures of what I am talking about: http://s13.postimage.org/78gqghflj/Screen_Shot_2012_07_09_at_2_03_41_PM.png http://s16.postimage.org/gdwus4w6t/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_50_PM.png http://s10.postimage.org/5uq3ste7d/i_OS_Simulator_Screen_shot_Jul_9_2012_2_02_57_PM.png http://s8.postimage.org/gpmsx959x/i_OS_Simulator_Screen_shot_Jul_9_2012_2_03_54_PM.png

  • AVPlayer seeking to a different point after app resume

    - by CGuess
    I have an AVPlayer, the video in it is ~2 seconds long. After the video plays, if the app goes to the background and reenters the foreground I need the video to still be shown exactly as it was when the app was exited. The AVPlayer sticks around just fine, however when I reenter the app from the background the video appears to be seeked to the middle of the video. However, if I just play the video, it starts from the beginning, so it doesn't seem like it actually seeked and is just showing a preview image. I've tried to auto-seek the video to the end on relaunch but nothing happens . Nothing I can figure out or find in the docs would describe this behavior. Any tips on having the video launch either at the beginning or end?

  • How to resize UILabel text after zooming UIScrollview zoomable

    - by netadictos
    I have an UIScrollview that is zoomable, the subview is one UIView (viewTexto) that contains an UILabel inside (messageLabel). This is the code - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollViewtmp{ return viewTexto; } -(void)scrollViewDidEndZooming:(UIScrollView *)scrollViewtmp withView:(UIView *)view atScale:(float)scale{ messageLabel.contentScaleFactor=scale; [scrollView setContentSize:CGSizeMake(scrollView.frame.size.width, messageLabel.frame.origin.y + messageLabel.frame.size.heightt)]; } With this code I can zoom, and the text is not blurry, there is no horizontal scroll but the size of the UILabel continues to be too large, so it is cut. I need that the width of the UILabel adopts to the scrollView width again as at the beginning. I have read any question about UIScrollViews in SO and having found exactly what I need.

  • UIView Login screen to tabbar logic

    - by Benjamin De Bos
    Folks, i'm having trouble with some navigation logic. Currently i have a simple two tabbed tabbar application. But i want to show a loginscreen in front. So that would be an UIView. Currently the code is as follows: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UIViewController *viewController1 = [[roosterViewController alloc] initWithNibName:@"roosterViewController" bundle:nil]; UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; self.tabBarController = [[UITabBarController alloc] init]; self.tabBarController.viewControllers = @[viewController1, viewController2]; self.window.rootViewController = self.tabBarController; [self.window makeKeyAndVisible]; return YES; } SO this pushes a simple tabcontroller. Well, now i want to have a login screen. So that would be a simple UIView which pushes the tabbar controller. But i can't seem to see the logic on how to do this. I've been trying to present a modal view controller, but the thing is: the tabbar will be loaded on the background. Since i need the username/password information to work on the tabbarview, this won't work. My Logic would be: delegate load loginViewController load tabbar controller But, then i need to be able to "logout". So i need to destroy the tabbar controller and present the login screen. Any thoughts on this?

    Today i would ask you if there is a way to call a method of another view controller just not initializing it or just how to get that viewController as a global variable declared in .h file.

I'm using a PageViewController and I have to use a method of the contentViewController alredy initialized. here I create my ViewControllers: - (void)createTheContent { NSLog(@"createTheContent"); pageController = nil; //[pageController removeFromParentViewController]; //[pageController awakeFromNib]; NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumber numberWithInteger:UIPageViewControllerSpineLocationMin] forKey: UIPageViewControllerOptionSpineLocationKey]; self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options: options]; pageController.dataSource = self; [[pageController view] setFrame:CGRectMake(0, 0, 320, 365)]; initialViewController = [self viewControllerAtIndex:0]; NSMutableArray *viewControllers = [NSArray arrayWithObject:initialViewController]; [pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil]; [self addChildViewController:pageController]; [[self view] addSubview:[pageController view]]; [pageController didMoveToParentViewController:self]; } here are my propertys in .h file: contentViewController *initialViewController; } //Page View Controller Properties @property (strong, nonatomic) UIPageViewController *pageController; @property (strong, nonatomic) NSArray *pageContent; @property (strong, nonatomic) NSMutableArray *pageStrings; @property (strong, nonatomic) id dataObject;

  • Raw Video file from website

    - by Charlie
    I would like to make an app that will download videos files that can be played later. At first i thought I could have a UIWeb view and then try to access the cache of it and get the file that way but unfortunately i don't have access to that. After trying that my next thought would be get the direct link to the video file. Essentially what download helper does on fire fox. Any idea of where i could look at for help or any body have any better idea? Is there any stringByEvaluatingjavascript that might be of use or is there away to access the cache on a webview in your own app? Thanks for any help!

  • UITableViewCell imageView images loading small even when they are the correct size!

    - by Alex Barlow
    Im having an issue whilst loading images into a UITableViewCell after an asynchronous download and placement into an UIImage variable.. The images appear smaller than they actually are! But when scrolled down and scrolled back up to the image, or the whole table is reloaded, they appear at the correct size... Here is a code excerpt... - (void)reviewImageDidLoad:(NSIndexPath *)indexPath { ThumbDownloader *thumbDownloader = [imageDownloadsInProgress objectForKey:indexPath]; if (thumbDownloader != nil) { UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:thumbDownloader.indexPathInTableView]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 0.0; [UIView commitAnimations]; cell.imageView.image = thumbDownloader.review.thumb; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 1.0; [UIView commitAnimations]; } } Here is an image of the app just after calling this method.. http://www.flickr.com/photos/arbarlow/5288563627/ After calling tableView reloadData or scrolling around the appear correctly, go the the next flickr image, to see the normal result, but im sure you can guess that.. Does anyone have an ideas as to make the images appear correctly? im absolutely stumped?! Regards, Alex iPhone noob

  • Completion block not being called. How to check validity?

    - by HCHogan
    I have this method which takes a block, but that block isn't always called. See the method: - (void)updateWithCompletion:(void (^)(void))completion { [MYObject myMethodWithCompletion:^(NSArray *array, NSError *error) { if (error) { NSLog(@"%s, ERROR not nil", __FUNCTION__); completion(); return; } NSLog(@"%s, calling completion %d", __FUNCTION__, &completion); completion(); NSLog(@"%s, finished completion", __FUNCTION__); }]; } I have some more NSLogs inside completion. Sometimes this program counter just blows right past the call to completion() in the code above. I don't see why this would be as the calling code always passes a literal block of code as input. If you're curious of the output of the line containing the addressof operator, it's always something different, but never 0 or nil. What would cause completion not to be executed?

  • UITapGestureRecognizer recognizing tap after scaling UIView

    - by Bikash Mishra
    I have a UIView which I scale to 4x after tapping on it. It works fine. On the next tap I want to restore it back to original size. The problem is that it recognizes the tap only in the smaller rectangle the UIView had before scaling. I would like to recognize the tap anywhere in the scaled UIView. How can I achieve it? //Tapping code titleCard = [[UIView alloc] initWithFrame: myrect]; [self addSubview:titleCard]; [titleCard release]; UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(changeSize:)]; [tapRecognizer setNumberOfTouchesRequired:1]; [tapRecognizer setNumberOfTapsRequired:1]; [titleCard addGestureRecognizer:tapRecognizer]; [tapRecognizer release]; //Scaling code CABasicAnimation *scale = [CABasicAnimation animationWithKeyPath:@"transform.scale"]; [scale setBeginTime:CACurrentMediaTime()+0.75]; [scale setDuration:0.5]; [scale setToValue: [NSNumber numberWithFloat:4.0f]]; [scale setRemovedOnCompletion:NO]; [scale setFillMode:kCAFillModeForwards]; Thanks.

  • UIPopover Sizing

    - by Echilon
    I have a UIPopoverController which I'm trying to show from a UIBarButtonItem in a navigation bar. Despite setting the resizing mask for the tableview inside the popover's content viewController, it takes up the whole height of the screen. The only thing which has any effect on the content size is menuPopover.contentViewController.view setFrame:CGRect. I'm using the code below to show the popover inside the left hand side of a UISplitViewController // menuPopover and editVc are properties on the parent viewController menuPopover = [[UIPopoverController alloc] initWithContentViewController:editVc]; [menuPopover presentPopoverFromBarButtonItem:btnMenu permittedArrowDirections:UIPopoverArrowDirectionAny animated:true]; [menuPopover setPopoverContentSize:CGSizeMake(400, 500) animated:true]; [menuPopover.contentViewController.view setFrame:CGRectMake(0,0,400, 500)]; Yet this is what I'm seeing. The arrow shows where the menu button was which showed the popover: http://imageshack.us/photo/my-images/545/screenshot20120312at191.png/ It's as though the content view is just expanding vertically.

  • Using NSURLRequest+NSURLConnection seems overkill for a webcall with no data return

    - by Spectravideo328
    All, This might seems very straightforward but I have already gone through the URL loading system program guide and the various NSURL.... classes and not found my answer. I am just trying to do a simple call from the app to a website to reserve a party spot: NSString *path=[NSString stringWithFormat:@"http://www.myparty123.com/ireservedURL.asp?Nickname=%@&Seat=%i&Email=%@&Currentparty=%i",john,5432,[email protected],6598]; NSURL* reservationURL =[NSURL URLWithString:path]; NSData *call= [NSData dataWithContentsOfURL:reservationURL]; This seemed to be the simple way but I get this warning that I am not using the "call" variable. And it seems overkill to do a call using NSData where there is no data return. Yet, creating an NSURLRequest and initiating an NSURLConnection and then implementing delegates with that request seems to be overkill as well. What am I missing. Thanks KMB

  • measure rendered html in javascript without affecting the measurement

    - by drawnonward
    I am doing pagination in javascript. This is typographic pagination, not chopping up database results. For the most part it works, but I have run into a heisenberg issue where I cannot quite measure text without affecting it. I am not trying to measure text before it is rendered. I want the actual position it shows up at on screen, so I can paginate to where it is naturally wrapped. I am measuring the vertical position of characters, not the horizontal width of strings. The way I do this is similar to this answer in that I am applying a style to a block of text, then measuring the position of the newly created span. If the span does not reach the end of the page, I clear it and make a new span in a linear search. The problem is that the anti-aliased sub-pixel text layout is different when the span is applied. In rare cases, this causes the text to wrap differently when I measure it. I have only seen this when wrapping at a hyphen, and I assume it would not happen when wrapping at white space. As a concrete example, "prepared-he" is the string I am having trouble with. When I measure up to "prepare" it appears, as expected, to be within the current page. When I measure "prepared" the whole phrase wraps down to the next line, moving it to the next page, so it looks like the "d" is the character to break at. I break the text between "prepare" and "d-he" and that is wrong. Trying to evaluate individual characters opens a whole can of worms I would rather avoid. The wrapping changes because, with the new span, the line is 1 pixel wider. A solution to my problem could either be a better way to measure text using javascript, or a way to wrap text in a new element without affecting layout. I have tried setting margin-right:-1px for the class of the span being created to wrap the text. This had no noticeable effect. I am doing this in a UIWebView on the iPhone. There are some measurement related calls that are available in normal WebKit that are not available here. For example, Range does not have getBoundingClientRect or support setting an offset other than 0 in setStart or setEnd. Thank you

  • How to disable other touch gestures after adding another tap gesture to the view?

    - by Hudson Duan
    I have a view with some tables and buttons on it, and then I want to add a tap gesture to the entire view, but I only want that gesture recognizer to recognize taps. Ideally, I want to do something when the added gesture recognizer is tapped, then remove that gesture recognizer after so the other buttons and tables can be accessed. Basically a tap to dismiss functionality that replicates something like the facebook notifications window, tap outside to dismiss, but not interfere with the buttons outside of the notifications view. Can anybody help? My current code is: NotificationsWindow *customView = [[[NSBundle mainBundle]loadNibNamed:@"NotificationsWindow" owner:self options:nil]objectAtIndex:0]; customView.frame= CGRectMake(12, 12, customView.frame.size.width, customView.frame.size.height); UITapGestureRecognizer *recognizerForSubView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehindAgain:)]; [recognizerForSubView setNumberOfTapsRequired:1]; recognizerForSubView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView addGestureRecognizer:recognizerForSubView]; [self.view addSubview:customView]; UITapGestureRecognizer *recognizerForSuperView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)]; [recognizerForSuperView setNumberOfTapsRequired:1]; recognizerForSuperView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView.superview addGestureRecognizer:recognizerForSuperView]; (void)handleTapBehind:(UITapGestureRecognizer *)sender { NSLog(@"tapped"); [[self.view.subviews lastObject] removeFromSuperview]; [self.view removeGestureRecognizer:sender]; } I want to make it so that the recognizer for the super view dismisses the subview, but not to interfere with the other taps on the super view.

  • addObjectsFromArray

    - by derek.lo
    I have a question about memory management when using the addObjectsFromArray method. Basically, I have 2 arrays defined in the appDelegate. I need these 2 arrays for the duration of my application's runtime. I therefore release them in my appDelegate's dealloc method. When I go to use these two arrays in a class, I want one array to store the values from the other, so that the other can have it's contents removed, but still stick around for use. Something like this: [appDelegate.arrayTwo addObjectsFromArray:appDelegate.arrayOne]; [appDelegate.arrayOne removeAllObjects]; I'm getting the compiler error: EXC_BAD_ACCESS because of a pointer issue? retaining issue? Any help would be greatly appreciated! Thanks

  • curios about CCSpriteBatchNode's addchild method

    when diving into "learn cocos2d game development with ios5", in ch08 in EnemyCache.m -(id) init { if ((self = [super init])) { // get any image from the Texture Atlas we're using CCSpriteFrame* frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"monster-a.png"]; batch = [CCSpriteBatchNode batchNodeWithTexture:frame.texture]; [self addChild:batch]; [self initEnemies]; [self scheduleUpdate]; } return self; } so batch is with texture "monster-a.png" in EnemyEntity.m's initWithType method switch (type) { case EnemyTypeUFO: enemyFrameName = @"monster-a.png"; bulletFrameName = @"shot-a.png"; break; case EnemyTypeCruiser: enemyFrameName = @"monster-b.png"; bulletFrameName = @"shot-b.png"; shootFrequency = 1.0f; initialHitPoints = 3; break; case EnemyTypeBoss: enemyFrameName = @"monster-c.png"; bulletFrameName = @"shot-c.png"; shootFrequency = 2.0f; initialHitPoints = 15; break; default: [NSException exceptionWithName:@"EnemyEntity Exception" reason:@"unhandled enemy type" userInfo:nil]; } if ((self = [super initWithSpriteFrameName:enemyFrameName])) { //... } so the returned object may be in 3 different frame. since Only the CCSprites that are contained in that texture can be added to the CCSpriteBatchNode, obviously, 'monster-b.png' is not contained in 'monster-a.png', why the different enemy can still be added to the batch?

  • Code to show UIPickerview under clicked UITextField

    - by Chris F
    I thought I'd share a code snippet where I show a UIPickerView when you click a UITextField. The code uses a UIPickerView, but there's no reason to use a different view controller, like a UITableViewController that uses a table instead of a picker. Just create a single-view project with a nib, and add a UITextField to the view and make you connections in IB. // .h file #import @interface MyPickerViewViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource, UITextFieldDelegate> - (IBAction)dismissPickerView:(id)sender; @end // .m file #import "MyPickerViewViewController.h" @interface MyPickerViewViewController () { UIPickerView *_pv; NSArray *_array; IBOutlet __weak UITextField *_tf; BOOL _pickerViewShown; } @end @implementation MyPickerViewViewController - (void)viewDidLoad { [super viewDidLoad]; _pickerViewShown = NO; _array = [NSArray arrayWithObjects:@"One", @"Two", @"Three", @"Four", nil]; _pv = [[UIPickerView alloc] initWithFrame:CGRectZero]; _pv.showsSelectionIndicator = YES; _pv.dataSource = self; _pv.delegate = self; _tf.delegate = self; _tf.inputView = _pv; } - (IBAction)dismissPickerView:(id)sender { [_pv removeFromSuperview]; [_tf.inputView removeFromSuperview]; [_tf resignFirstResponder]; _pickerViewShown = NO; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField { if (!_pickerViewShown) { [self setRectForPickerViewRelativeToTextField:textField]; [self.view addSubview:_tf.inputView]; _pickerViewShown = YES; } else { [self dismissPickerView:self]; } return NO; } - (void)setRectForPickerViewRelativeToTextField:(UITextField*)textField { CGFloat xPos = textField.frame.origin.x; CGFloat yPos = textField.frame.origin.y; CGFloat width = textField.frame.size.width; CGFloat height = textField.frame.size.height; CGFloat pvHeight = _pv.frame.size.height; CGRect pvRect = CGRectMake(xPos, yPos+height, width, pvHeight); _pv.frame = pvRect; } - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { return [_array objectAtIndex:row]; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return _array.count; } - (void) pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { _tf.text = [_array objectAtIndex:row]; [self dismissPickerView:self]; } @end

    I have an iPad app that has a UISearchBar in its navigation bar. When I enter text in the search bar the results are automatically displayed in a UIPopOverController. That's great except the popover's default size is not wide enough for my needs. Is there a way to set its width? Apple has done this themselves with Safari's search bar. The popover that displays search results is a good bit wider than the default and they have removed the "Results" title from the popover.
