  • Removing views from UIScrollView

    - by mohan
    I have two UIScrollViews that I move images between. The user can drag and forth between the scroll views. I am trying to animate the movement of the image from one scroll view to another. In -touchesMoved (handled in my UIViewController which has two custom UIScrollViews that intercept touch and sends to my UIViewController), I am trying to set the "center" of my UIImageView that is being moved. As it is moved, the image gets hidden behind the UIScrollView and not visible. How do I make it appear on top of the UIScrollView? I am able to handle the -touchesEnded properly by animating in the destination scroll view. I am also confused about -convertPoint:fromView: usage in the iPhone Programming Guide (See Chapter 3, Event Handling). If the touch coordinates are in window coordinates, to change my view (UIImageView inside a UIScrollView which is inside a UIView and inside a window) center don't I have to use -convertPoint:toView:, i.e., imageView.center = [self.view.window convertPoint:currentTouchPosition toView:imageView]; What am I missing?

  • problem in basic implementation of MVVM pattern - Services

    - by netmajor
    I watch some video and read articles about MVVM pattern and start thinking how should I implement it in my Silverlight app. So at first I create Silverlight application. I think that for clear view I create 3 folders: View - for each user control page in my app, ViewModel - for c# class which will querying date and Model- Entity Data Model of my SQL Server or Oracle Database. And now I am confused, cause I want to implement *WCF/RIA Services/Web services* in my project. In which folder should I put in class of services? I see in examples that Services take date and filtering it and then output data was binding in View - so It looks as ViewModel. But I was sure that someone use Services in Model and that I want to do. But how? Can someone explain me implementing Services as Model? Is my point of view at MVVM is correctly?

  • iPad: Detecting External Keyboard

    - by StuartW
    My app uses a UIAccessoryView to provide additional keyboard functionality (such as forward/backward tabs and arrows keys) for the virtual keyboard, but that causes UIKeyboardDidShowNotification to fire even when a physical keyboard is present (the accessory appears at the bottom of the screen). I'd like to check if a physical keyboard is attached when handling UIKeyboardWillShowNotification, to prevent the accessory view from appearing and to prevent my custom view from scrolling up (to make room for the non-existent virtual keyboard). I've tried examining the UIKeyboardFrameEndUserInfoKey key, but it returns a real size for the virtual keyboard, in spite of nothing being displayed. Is there any way to detect the presence of a physical keyboard to prevent this unwanted behaviour? Hmm, the plot thickens. I tried disabling the input accessory by returning nil from the inputAccessoryView property of the Responder object which triggers the keyboard. That suppresses UIKeyboardWillShowNotification and UIKeyboardDidShowNotification when there is a physical keyboard present, but keeps these notifications when there is no such keyboard. All good so far. Then I tried re-enabling inputAccessoryView only after UIKeyboardWillShowNotification had been received. This only fires when a virtual keyboard is needed, so it should allow me to reintroduce the accessory view in those circumstances. Or so I thought. Unfortunately, it seems the OS doesn't check inputAccessoryView after UIKeyboardWillShowNotification, so it fails to show the accessory view when it is needed :o( That leaves me with two options: Include the input accessory view, giving extra functionality for virtual keyboard users, but lose the ability to detect a physical keyboard and hence not supporting physical devices; or Exclude the input accessory altogether, preventing most users from accessing the extra keys, but allowing the app to work with a physical keyboard. Not a great choice, so I'm still keen to see if anyone else has addressed this problem!

  • when/where should properties be released once the objects is pushed for display?

    - by Tzur Gazit
    Hi, I've defined a view controller with an array as one of its properties, and set the array with an allocated and autoreleased array. After I push the view for display I release it. By watching the leaks tool I see that every time that I pop the view I suffer from leakage. I tried to release the properties explicitly, immediately after the push but the app crashes. looking forward for your suggestions.

  • In ASP.NET MVC, why can't I inherit from "MyCustomView" without specifying the full type name?

    - by Seth Petry-Johnson
    In my MVC apps I normally declare a base view type that all of my views inherit from. I get a parser error when I specify Inherits="MyView" in my Page declaration, but not if I specify Inherits="MyApp.Web.Views.MyView". Strangely enough, it also works fine if I specify Inherits="MyView<T> (where T is any valid type). Why can I specify a strongly typed view without the full type name, but not a generic view? My base view class is declared like this: namespace MyApp.Web.Views { public class MyView : MyView<object> { } public class MyView<TModel> : ViewPage<TModel> where TModel : class { } }

  • Why won't my CATiledLayer scroll in a UIScrollView after zooming?

    - by Brodie4598
    I'm currently having the following problem with CATiledLayer: when the view first loads, the scrolling works perfectly, but then when you zoom once, the view snaps to the anchor point (top left corner) and it can no longer scroll at all. The zooming works in that it will zoom in and out, but it will only zoom to the top left corner. My code is as follows: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

  • Height of tableHeaderView seems to be 0

    - by gabac
    I tried to override the second tableHeaderView. But it seems that the height of it in the method heightForHeaderInSection seems to be 0. Can't explain it, do I have to put it in a iVar because in the viewForHeaderInSection I can set the view without any problems. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Adding a new list"; else return @"Other lists"; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if(section == 0) { return tableView.tableHeaderView; } else { UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)] autorelease]; view.backgroundColor = [UIColor redColor]; return view; } } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if(section == 0) return tableView.tableHeaderView.frame.size.height; else return 30; }

  • Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

    - by BeachRunnerJoe
    I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

  • popToRootViewControllerAnimated and dealloc all views

    - by mongeta
    Hello again, I have a UINavigationController that asks for some information and the user navigates until the end, once there, they can Accept or Cancel all the data that has been entered. It doesn't matter wich option they choose, as they always will go to the first view using [UINavigationController popToRootViewControllerAnimated:] The question is, how I can release/deallocate all the views ? For example, they start for view 1 and the end is at view 8, once they go directly to the 1 from the 8, how I can release view 2,3,4,5,6,7,8 ? thanks, regards, m.

  • UIVIewController wrong position before rotate

    - by zegnus
    I have the starter point of my application this window (white background): - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { mainScreen = [[MainScreenController alloc] initWithNibName:@"MainScreenController" bundle:[NSBundle mainBundle]]; // add it to the main window [window addSubview:[mainScreen view]]; // show view [window makeKeyAndVisible]; NSLog(@"started"); return YES; } And MainScreenController is an UIViewController with (blackBackground) created by the Interface Builder. The application executes perfectly but the first time, the black view is moved up like the height of the status iphone pannel (leaving white rectangle at the bottom). If I rotate the iPhone twice, the view is perfectly positioned in the right place, filling all the screen with the black background. Any idea? Thanks!

  • UIView Obscuring Other Views

    - by Matt Long
    I cannot figure out what is obscuring my buttons. The first image shows the buttons that I want to click. They are clickable while the view is contracted like this, but when the view is expanded like in the second image, the buttons are no longer clickable. There seems to be another view obscuring the buttons. Any thoughts on what might be causing that? If not, any idea how I can figure out what view is getting the tap events when I tap in that area? Thanks. -Matt

  • Two UITabBarControllers and Autorotation

    I have two UITabBarControllers in my mainwnidow.nib wired to my appdelegate. In my app delegate, I can load either one: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //either [window addSubview:tabBarController.view]; //or [window addSubview:tabBar2Controller.view]; [window makeKeyAndVisible]; } and autorotation works. If I add both (with the expectation to swap between them later): [window addSubview:tabBarController.view]; [window addSubview:tabBar2Controller.view]; then autorotation stops working...everything is always portrait. Thanks in advance for any tips...

  • Mapping composite foreign keys in a many-many relationship, with overlapping components.

    - by Kirk Broadhurst
    I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: gstreamer0.10-plugins-ugly:i386 : Depends: libdvdread4:i386 but it is not going to be installed E: Unable to correct problems, you have held broken packages. This means that I can't play mp3s (among other things) in 32-bit applications that use gstreamer. Is there a way around this?

  • How to have multiple tables with multiple joins

    - by williamsdb
    I have three tables that I need to join together and get a combination of results. I have tried using left/right joins but they don't give the desired results. For example: Table 1 - STAFF id name 1 John 2 Fred Table 2 - STAFFMOBILERIGHTS id staffid mobilerightsid rights --this table is empty-- Table 3 - MOBILERIGHTS id rightname 1 Login 2 View and what I need is this as the result... id name id staffid mobilerightsid rights id rightname 1 John null null null null 1 login 1 John null null null null 2 View 2 Fred null null null null 1 login 2 Fred null null null null 2 View I have tried the following : SELECT * FROM STAFFMOBILERIGHTS SMR RIGHT JOIN STAFF STA ON STA.STAFFID = SMR.STAFFID RIGHT JOIN MOBILERIGHTS MRI ON MRI.ID = SMR.MOBILERIGHTSID But this only returns two rows as follows: id name id staffid mobilerightsid rights id rightname null null null null null null 1 login null null null null null null 2 View Can what I am trying to achieve be done and if so how? Thanks

  • Need some serious help with self join issue.

    - by kralco626
    Well as you may know, you cannot index a view with a self join. Well actually even two joins of the same table, even if it's not technically a self join. A couple of guys from microsoft came up with a work around. But it's so complicated I don't understand it!!! The solution to the problem is here: http://jmkehayias.blogspot.com/2008/12/creating-indexed-view-with-self-join.html The view I want to apply this work around to is: create VIEW vw_lookup_test WITH SCHEMABINDING AS select count_big(*) as [count_all], awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm [owner], t.circt_cstdn_nm [tech], dvc.circt_nm, data_orgtn_yr from ((dbo.dvc join dbo.circt on dvc.circt_nm = circt.circt_nm) join dbo.circt_cstdn o on circt.circt_cstdn_user_id = o.circt_cstdn_user_id) join dbo.circt_cstdn t on dvc.circt_cstdn_user_id = t.circt_cstdn_user_id group by awc_txt, city_nm, str_nm, stru_no, o.circt_cstdn_nm, t.circt_cstdn_nm, dvc.circt_nm, data_orgtn_yr go Any help would be greatly apreciated!!! Thanks so much in advance!
