    This shouldn't be this confusing. I have a custom UIView with a bunch on controls on it. UILabels, buttons, etc. I've created this Nib using Interface Builder. I want to be able to position this custom uiview on another UIView using the interface builder. How do I link my UIView custom class, to the nib? initWithCoder gets called, but I want this class to get loaded from the nib. Thanks

  • MPMoviePlayerController fullscreen movie inside a UIWebView

    - by Wakazors
    Hi, I'm having a problem with the UIWebView and MPMoviePlayerController: My UIWebView have a movie inside the html (it's a local html file), I'm using html5 and a video tag for the video. The problem is: the user can set the video to play inline, directly on the html or he can tap the fullscreen button, but I need to know if the video is playing fullscreen. I've tried to use MPMoviePlayerDidEnterFullscreenNotification but with no success. Does anybody know how to get this notification from the webview? Thanks in advance

  • Empty "Groups" in People Picker Navigation Controller

    - by Meltemi
    I'm using the standard People Picker Navigation Controller to let users associate one of their contacts with one of my objects. It presents itself as a long list of ALL contacts. The back button (top left) says "Groups" but when clicked on it shows an empty screen...even when there are many Groups in the user's address book. I've read through the docs and can't seem to find how to populate the Groups area. Here's how I present the people picker. Fairly standard: - (IBAction)showPicker:(id)sender { ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; [self presentModalViewController:picker animated:YES]; [picker release]; } What am I missing?

  • Passing touch events on to subviews

    - by Egil Jansson
    I have a view within a UIScrollView that loads an additional subview when the user presses a certain area. When this additional subview is visible, I want all touch events to be handled by this - and not by the scrollview. It seems like the first couple events are being handled by the subview, but then touchesCancelled is called and the scrollview takes over the touch detection. How can I make sure that the subview gets all the events as long as the movement activity is being performed on this view? This is my implementation on touchesMoved - which I thought would do the job... -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[touches allObjects] objectAtIndex:0]; CGPoint touchPt = [touch locationInView:self]; UIView *hitView = [self hitTest:touchPt withEvent:event]; UIView *mySubView = subviewCtrl.view; if(hitView == mySubView) { [subviewCtrl.view touchesMoved:touches withEvent:event]; } else { NSLog(@"Outside of view..."); } }

  • Search and display buisness locations on MKMapView

    - by jmurphy
    Hello, I'm trying to find a way to search for a business, such as "grocery stores" and display them on a google map around the users current location. This used to be pretty simple with the old URL style of launching the apple map location but I can't find out how to do it with the MKMapView. I understand that I'll need to use the MKAnnotations classes but my problem is with finding the data. I've tried plugging in the URL below to get the info from google but the size of the data seems way too large. http://maps.google.com/maps?q=grocery&mrt=yp&sll=37.769561,-122.412844&z=14&output=kml Is there an easy way to just set a property that tells the MKMapView to search for a keyword and display all matching business around my current location? Or does anybody know how to get this information from google?

  • iPad: Move UIView with animation, then move it back

    - by Joel
    I have the following code in a UIView subclass that will move it off the screen with an animation: float currentX = xposition; //variables that store where the UIView is located float currentY = yposition; float targetX = -5.0f - self.width; float targetY = -5.0f - self.height; moveX = targetX - currentX; //stored as an instance variable so I can hang on to it and move it back moveY = targetY - currentY; [UIView beginAnimations:@"UIBase Hide" context:nil]; [UIView setAnimationDuration:duration]; self.transform = CGAffineTransformMakeTranslation(moveX,moveY); [UIView commitAnimations]; It works just great. I've changed targetX/Y to 0 to see if it does indeed move to the specified point, and it does. The problem is when I try and move the view back to where it was originally: moveX = -moveX; moveY = -moveY; [UIView beginAnimations:@"UIBase Show" context:nil]; [UIView setAnimationDuration:duration]; self.transform = CGAffineTransformMakeTranslation(moveX,moveY); [UIView commitAnimations]; This puts the UIView about 3x as far as it should. So the view usually gets put off the right side of the screen (depending on where it is). Is there something with the CGAffineTransforMakeTranslation function that I should know? I read the documentation, and from what I can tell, it should be doing what I'm expecting it to do. Anyone have a suggestion of how to fix this? Thanks.

  • Test Driven Development (TDD) in Visual Studio 2010- Microsoft Mondays

    - by Hosam Kamel
    November 14th , I will be presenting at Microsoft Mondays a session about Test Driven Development (TDD) in Visual Studio 2010 . Microsoft Mondays is program consisting of a series of Webcasts showcasing various Microsoft products and technologies. Each Monday we discuss a particular topic pertaining to development, infrastructure, Office tools, ERP, client/server operating systems etc. The webcast will be broadcast via Lync and can viewed from a web client. The idea behind the “Microsoft Mondays” program is to help you become more proficient in the products and technologies that you use and help you utilize their full potential.   Test Driven Development in Visual Studio 2010 Level – 300 (  Intermediate – Advanced ) Test Driven Development (TDD), also frequently referred to as Test Driven Design, is a development methodology where developers create software by first writing a unit test, then writing the actual system code to make the unit test pass.  The unit test can be viewed as a small specification around how the system should behave; writing it first helps the developer to focus on only writing enough code to make the test pass, thereby helping ensure a tight, lightweight system which is specifically focused meeting on the documented requirements. TDD follows a cadence of “Red, Green, Refactor.” Red refers to the visual display of a failing test – the test you write first will not pass because you have not yet written any code for it. Green refers to the step of writing just enough code in your system to make your unit test pass – your test runner’s UI will now show that test passing with a green icon. Refactor refers to the step of refactoring your code so it is tighter, cleaner, and more flexible. This cycle is repeated constantly throughout a TDD developer’s workday. Date:   November 14, 2011 Time:  10:00 a.m. – 11:00 a.m. (GMT+3)  http://www.eventbrite.com/event/2437620990/efbnen?ebtv=F   See you there! Hosam Kamel Originally posted at

  • Setting a UITableViewCell accessory type on some cells, but not all

Right now I am building it in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath though I am fully aware it is going to add a disclosure indicator to every cell cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

  • Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

    - by LucasTizma
    I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

  • Notifying view controller when subview touch events occur.

    - by Nebs
    I have a UIViewController whose view has a custom subview. This custom subview needs to track touch events and report swipe gestures. Currently I put touchesBegan, touchesMoved, touchesEnded and touchesCancelled in the subview class. With some extra logic I am able to get swipe gestures and call my handleRightSwipe and handleLeftSwipe methods. So now when I swipe within the subview it calls its local swipe handling methods. This all works fine. But what I really need is for the handleRightSwipe and handleLeftSwipe methods to be in the view controller. I could leave them in the subview class but then I'd have to bring in all the logic and data as well and that kind of breaks the MVC idea. So my question is is there a clean way to handle this? Essentially I want to keep my touch event methods in the subview so that they only trigger for that specific view. But I also want the view controller to be informed when these touch events (or in this case swipe gestures) occur. Any ideas? Thanks.

  • iPhone SDK: TextView, Keyboard in Landscape mode

    - by Arnold
    Hello. How do I make sure that the textview is shown and the keyboard is not obscuring the textview, while in landscape. Using UICatalog I created a TextViewController which works. In it there are two methods for calling the keyboard and making sure that textView is positioned above the keyboard. his just works great in Portrait mode. I got the Landscape mode working, but on the textView is still being put to the top of the iPhone to compensate for the keyboard in portrait mode. I changed the methods for showing the keyboards. Below is the code for this methods: (I will just let see the code for show, since the hide code will be the reverse.. - (void)keyboardWillShow:(NSNotification *)aNotification { UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; if (orientation == UIInterfaceOrientationPortrait) { // the keyboard is showing so resize the table's height CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue]; NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]; CGRect frame = self.view.frame; frame.size.height -= keyboardRect.size.height; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; } else if (orientation == UIInterfaceOrientationLandscapeLeft) { NSLog(@"Left"); // Verijderen later CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue]; NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]; CGRect frame = self.view.frame; frame.size.width -= keyboardRect.size.height; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; } else if (orientation == UIInterfaceOrientationLandscapeRight){ NSLog(@"Right"); // verwijderen later. CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue]; NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]; CGRect frame = self.view.frame; frame.size.width -= keyboardRect.size.width; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; } } I know that I have to change the line frame.size.height -= keyboardRect.size.height but I do not seem to get it working. I tried frame.size.width -= keyboardRect.size.height that did not work. Losing the keyboardRect and frame all together work, however off course the keyboard obscures the textview........

  • Custom UITableViewCell won't redraw on setNeedsDisplay

    - by Andrew Portner
    I created a custom UITableViewCell class with a UIButton, a UIImage, and two UILabels. The button and the image are overlayed on top of each other, and only one is displayed at a time. The expected behavior is you touch on the button, the button disappears, and it displays the image. The UITableViewCells are set to be reused. Here's my code: Constructor: - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) { unheartButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; unheartButton.backgroundColor = [UIColor clearColor]; unheartButton.frame = CGRectMake(10, 13, 20, 18); [unheartButton addTarget:self action:@selector(onButtonClick:) forControlEvents:UIControlEventTouchUpInside]; [unheartButton setBackgroundImage:[UIImage imageNamed:@"redheart.png"] forState:UIControlStateNormal]; imageView = [[UIImageView alloc] init]; imageView.frame = CGRectMake(12, 13, 16, 16); NSMutableArray *array = [[NSMutableArray alloc] init]; for (int ndx = 1; ndx < 13; ndx++) { [array addObject:[UIImage imageNamed:[NSString stringWithFormat:@"icon-loading-%d (dragged).tiff", ndx]]]; } imageView.animationImages = array; imageView.animationDuration = 1; imageView.hidden = YES; [array release]; [self.contentView addSubview:imageView]; [self.contentView addSubview:unheartButton]; return self; } } Button click: - (IBAction) onButtonClick: (id) sender { unheartButton.hidden = YES; imageView.hidden = NO; [imageView startAnimating]; [self setNeedsDisplay]; [self.contentView setNeedsDisplay]; [self.unheartButton setNeedsDisplay]; [self.imageView setNeedsDisplay]; } I'm calling setNeedsDisplay on everything, but nothing seems to happen. If I scroll off the screen and back up, the button is hidden and now the loading icon is shown, but this only happens after a scroll. I'm not sure what I need to do to get the cell to repaint.

    Good Day! i want to use nsthreads in a project of xcode that will call a function which is for the network access and will check that if the network is there or not, so i need to have a thread which will execute after lets say 1 minutes to check the connectivity. and will continue run unless the app is closed. [NSThread detachNewThreadSelector:@selector(startTheBackgroundJob) toTarget:self withObject:nil]; startTheBackgroundJob NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // wait for 3 seconds before starting the thread, you don't have to do that. This is just an example how to stop the NSThread for some time [NSThread sleepForTimeInterval:5]; //[self performSelectorInBackground:@selector(checkNet) withObject:nil]; [self performSelectorOnMainThread:@selector(checkNet) withObject:nil waitUntilDone:YES]; [pool release]; it works only for the first time but not any other, i mean only 1 loop it makes can somebody help me in this regard.

  • How do I change the frame position for a custom MKAnnotationView?

    - by andrei
    I am trying to make a custom annotation view by subclassing MKAnnotationView and overriding the drawRect method. I want the view to be drawn offset from the annotation's position, somewhat like MKPinAnnotationView does it, so that the point of the pin is at the specified coordinates, rather than the middle of the pin. So I set the frame position and size as shown below. However, it doesn't look like I can affect the position of the frame at all, only the size. The image ends up being drawn centered over the annotation position. Any tips on how to achieve what I want? MyAnnotationView.h: @interface MyAnnotationView : MKAnnotationView { } MyAnnotationView.m: - (id)initWithAnnotation:(id <MKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier]) { self.canShowCallout = YES; self.backgroundColor = [UIColor clearColor]; // Position the frame so that the bottom of it touches the annotation position self.frame = CGRectMake(0, -16, 32, 32); } return self; } - (void)drawRect:(CGRect)rect { [[UIImage imageNamed:@"blue-dot.png"] drawInRect:rect]; }

  • grails prod run-app connects to mysql but grails prod run-war doesn't

    - by damian
    Hi, I have a unexpected problem. I had create a war with grails war. Then I had deployed in Tomcat. For my surprise the crud works fine but I don't know what persistence is using. So I did this test: Compare grails prod run-app with grails prod run-war. The first works fine, and does conect with the mysql database. The other don't. This is my DataSource.groovy: dataSource { pooled = true driverClassName = "com.mysql.jdbc.Driver" username = "grails" password = "mysqlgrails" } hibernate { cache.use_second_level_cache=false cache.use_query_cache=false cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { dataSource { dbCreate = "update" // one of 'create', 'create-drop','update' url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } test { dataSource { dbCreate = "update" // one of 'create', 'create-drop','update' url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } production { dataSource { dbCreate = "update" url = "jdbc:mysql://some-key.amazonaws.com/MyDB" } } } Also I extract the war to see if I could find some data source configuration file without success. More info: Grails version: 1.2.1 JVM version: 1.6.0_17 Also I think this question it's similar, but doesn't have a awnser.
