  • Timed selector never performed

    - by sudo rm -rf
    I've added an observer for my method: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(closeViewAfterUpdating) name:@"labelUpdatedShouldReturn" object:nil]; Then my relevant methods: -(void)closeViewAfterUpdating; { NSLog(@"Part 1 called"); [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil afterDelay:2.0]; } -(void)closeViewAfterUpdating2; { NSLog(@"Part 2 called"); [self dismissModalViewControllerAnimated:YES]; } The only reason why I've split this method into two parts is so that I can have a delay before the method is fired. The problem is, the second method is never called. My NSLog output shows Part 1 called, but it never fires part 2. Any ideas? EDIT: I'm calling the notification from a background thread, does that make a difference by any chance? Here's how I'm creating my background thread: [NSThread detachNewThreadSelector:@selector(getWeather) toTarget:self withObject:nil]; and in getWeather I have: [[NSNotificationCenter defaultCenter] postNotificationName:@"updateZipLabel" object:textfield.text]; Also, calling: [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil]; does work. EDITx2: I fixed it. Just needed to post the notification in my main thread and it worked just fine.

  • UIButtons display differently on UIImageView when created at design time vs. run time

    - by PRITISH
    I have added some UIButton objects into .xib file, and some UIButton objects with the code. But now I am facing one problem. While Zooming the UIImageView the UIButtons that are added through code are shown on the UIImageView and those that are added with .xib file are below the UIImageView. Code for UIButtons added with code: btnBrightness = UIButton.FromType (UIButtonType.RoundedRect); btnBrightness.Frame = new RectangleF (540, 20, 95, 37); btnBrightness.SetTitle ("Brightness", UIControlState.Normal); More details: monotouch

  • Completely Removing Views from memory

    - by cannyboy
    I have a view which is set up to train 'voiceprints' of words (this voiceprint code is not mine), and another view which has a slideshow which is controlled by the voiceprint. Unfortunately, these views conflict because they are still in memory. As far as I know, viewDidUnload and dealloc are only called in low-memory situations, and dealloc should not be called directly, so how do I completely remove a view. These views are within uinavigationcontrollers by the way.

  • How to read file.xml from resources to NSString with format?

    - by falkon
    Actually I have such a code: NSString *path = [[NSBundle mainBundle] pathForResource: @"connect" ofType: @"xml"]; NSError *error = nil; NSString *data = [NSString stringWithContentsOfFile: path encoding: NSUTF8StringEncoding error: &error]; NSString *message = [NSString stringWithFormat:data, KEY, COUNTRY_ID]; which reads the connect.xml from resources. But on the formating the string (message) APP quits without displaying any errors. How can I read file.xml from resources to NSString with format?

  • Popovercontroller doesn't display full

    - by user2959234
    I have an UIPopovercontroller in with an content that generate from an viewcontroller. popOverController = [[UIPopoverController alloc]initWithPopUp:emLightPopUp]; popOverController.delegate = self; // Get device position. CGRect position = {parentButton.frame.origin,emLightPopUp.popUpView.frame.size}; CGSize popUpViewFrameSize = emLightPopUp.popUpView.frame.size; Link screenshot: http://i.stack.imgur.com/AxqoG.png The issue is that when I change the position of select devices (touched button) upwards, the displayed popup will be resized like the screenshot. I already try to set content size inside the subclass of uipopover but it still doesn't work: self.popoverContentSize = emLightPopUp.popUpView.frame.size; EDIT: I solved this problems by calculate the position that display the popup and scroll the scrollview inside into an upper position. Check out this code: -(void)moveDeviceOutMiddleScreen:(id)deviceButton { UIButton* button = (UIButton*)deviceButton; CGFloat yPositionRange = button.frame.origin.y - self.floorZoomScrollView.contentOffset.y; int middle_top_y = 70; int middle_bottom_y = 166; if (yPositionRange > middle_top_y && yPositionRange < middle_bottom_y) { CGRect newRect = CGRectMake(self.floorZoomScrollView.contentOffset.x, self.floorZoomScrollView.contentOffset.y +yPositionRange*0.6, self.floorZoomScrollView.frame.size.width, self.floorZoomScrollView.frame.size.height); [self.floorZoomScrollView scrollRectToVisible:newRect animated:NO]; } } Thanks for your responses.

  • Collision detection on sub views contained in 2 separate parent UIViews?

    - by Chris
    Hi All, I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected. So originally within the ViewController it was comparing 2 UIviews. Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic. My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this. Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?

  • What's the consequence when Core Data detects an optimistic locking failure when trying to save?

    - by dontWatchMyProfile
    I get it: When a managed object context saves, the snapshots of all edited objects are compared against the values in the persistent store to see if the PS has changed since the snapshot was made. If it did change, then there's a conflict and optimistic locking failed, according to Apple. But now, what's the consequence of this? What happens next? What are my options in this case?

  • Scroll the entire page with with UITableView that doesn't take up the entire screen

    - by KJF
    The only UITableViews I have worked with thus far are sized to fill the entire page. I'm trying to create a page in my app where I will have an image and a label on the top of the page followed by a UITableView to hold comments below it. Something like this springs to mind: http://www.inquisitr.com/wp-content/fbb.jpg My problem is if I add a UITableView below the image and label, when I scroll the tableview then only the UITableView cells scroll. Not the entire page. How would I go about making the entire page scroll so that the label and image scroll off the page and more table cells appear? Thanks.

  • How does one access subviews and handle groups of them?

    - by david
    If I want to manipulate a view I get it with [self viewWithTag:5];. Is there a better way to do this? Sometimes I need to manipulate a bunch of view (e.g. move them all out of the way. I do this by adding a UIView (e.g. UIView iHoldViews) and then adding the views, buttons, etc to this view. Then I can move the iHoldViews view and all its subviews move with it. Is there a better way to do this? (I have a feeling there is :) Maybe storing them in a NSArray or NSMutableDictionary ?
