• iphone - creating a reference to a MPMoviePlayerController

  - by Mike

  At some point in my code I am creating a MPMoviePlayerController object and playing it. As I need to reference this object at some other methods in my code that runs asynchronously, I need to store a pointer to the movie object etc., so I can use that. Declaring MPMoviePlayerController * myMovie on the header file is out of question, because the compiler will give me an error saying "expected specifier-qualifier-list before 'MPMoviePlayerController'". If it was a view I could do something like [self.view viewWithTag:99]; to get the object, but the MPMoviePlayerController does not allow this. How can I obtain the movie object or store a reference to it, so I can call the object in other methods? thanks for any help.

• iphone - UITapGestureRecognizer problem

  - by Mike

  I have two UIImageViews one as subview of the other. The subview is smaller and is centered on the screen. Both have UITapGestureRecognizer assigned and both were intended to respond to single taps. A single tap on the main view (= the area outside the subview) is fine, but a tap inside the subview is seen as the main view as a tap too. How can I have this to work independently? both views have setCancelsTouchesInView and setDelaysTouchesEnded set to NO and both have the same delegate (yes, I need to have the same delegate and cannot change that). How may I force the main view to ignore any tap on the area that belongs to its subview? thanks for any help.

• Desktop development versus Web development

  - by eKek0

  What are the advantages and disadvantages of one model and the other? Why and when would you choose one or the other? If you were going to build a business application, which is the best approach for you? To make this a fair question, is better if you post only quantified non-subjective answers.

• iPhone OS 3.2 File Sharing Path

  - by OscarTheGrouch

  Currently I have this for my file path and file... NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"Shared\PartyPlanner.sqlite"]]; This allows me to share the file with iTunes, but instead of just having 'PartyPlanner.sqlite' in the 'applicationDocumentsDirectory\Shared' I have "SharedPartyPlanner.sqlite" in the 'applicationDocumentsDirectory' is there a cleaner or easier way to get to the shared folder inside of applicationDocumentsDirectory?

• iphone - UIImagePickerController compressing video?

  - by Mike

  I am using a UIImagePickerController to get a video from the library. So, I am using this picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; picker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:picker.sourceType]; picker.allowsEditing = NO; picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie]; [self presentModalViewController:picker animated:YES]; [picker release]; As soon as I select the video and tap on CHOOSE, I see the message "Compressing Video" and it stays ages stuck... I waited for 5 minutes and the message was still there. Is there a way to prevent this? Why I cannot simply take a copy of the move as it is. I do not want any compressing... is there a way to solve this? thanks.

• iphone - keeping the last frame of a frame animation visible

  - by Mike

  I have this code UIImageView *sequence = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"balao_surge0.png"]]; NSMutableArray *array = [[NSMutableArray alloc] init] ; for (int i=0; i<30; i++) { UIImage *oneImage = [UIImage imageNamed:[NSString stringWithFormat:@"balao_surge%d.png",i]]; [array addObject:oneImage]; } sequence.animationImages = array; sequence.animationDuration = 2.0; sequence.animationRepeatCount = 1; [umaVista addSubview:sequence]; [sequence release]; sequence.startAnimating; The animation plays fine, but after the last frame is shown, it vanishes. I would like to make it stay visible, that is, make the animation stop on the last frame. Is there any way to do that? thanks for any help.

• iphone - making the CGAffineTransform permanent

  - by Mike

  I am banging my head on the wall here due to this problem: When I create a UIImageView this view has a certain orientation and size. Lets call this state "A". This view responds to taps. It can be dragged around the screen. At some point in the code I apply a CGAffineTransform to the view. Does not matter if the affine is a scale, a rotation, a translation or a combination of all. Does not matter also if the transform is absolute or relative. Not to mention the device can change its orientation and the view is autorotated to the correct orientation (that we can cay is a kind of rotation or transformation applied to the view). The problem is: the moment I touch that object or try to animate its transparency or any other parameter, it "remembers" the state "A" and does all animations from that state, not from current state. If I simply touch the view, it returns instantly to state "A". The code is not doing it by itself. It is an annoying "gift" from Apple. How to I make a view assume its current state of transformations as the reset or initial state? In other words, how do I make a view forget its past transformations or states? The only way I know is recreating the view, but this is a ridiculous way of doing this. Is there any way to make this work as I described? thanks

• UIImages not displaying in TableView on iPhone, but working in Simulator

  - by Graeme

  Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. It's just a blank white space. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

• Edit, select value from UITableView on the iPhone

  - by Anthony D

  I have a UITableView with a list of names, representing server configurations. I want the user to be able to select a server configuration, add a server config, edit a server config, or just cancel out of the view and return to the main view. I'm having a hard time trying to figure out how to achieve all of that functionality in this view. To select, the user should be able to just tap the server config name and a check will appear next to the name then the user is taken back to the main view automatically (or use a save button instead?). To edit the server config, I would also like the user to be able to tap the server config name and be taken to a detail screen where changes can be made. How can I accomplish both since I want both to be done by tapping the server name (row)? Right now the cancel button seems out of place since the screen is accessed via a UINavigationController. Any suggestions?

• iphone - button outside MPMoviePlayerController window not responding

  - by Mike

  I have created a MPMoviePlayerController to play a movie. As the movie likes to play landscape in full screen, when the movie is about to play, I grab its window and resize it to be smaller. At the same time, I add a view to the movie's window and this view contains several buttons, that are supposed to be around the movie. As the movie's window is reduced in size, I have to scale the buttons' view up, so the buttons do not reduce in size. I ended with this What you can see here is this: four buttons (green rectangles), the reduced movie's window and the application's window, that now is visible because the movie's window was reduced. The problem is that the buttons just work if you click on their regions inside the movie's window (A). If you click them on the region outside (B) they don't work. WHen you click on B, TouchesMoved on the main view controller receives the touch and the button doesn't do its action. How can this be solved? thanks for any help

• iPhone - move above buttons

  - by Mike

  I have a video at 320x240 on the middle of the screen area. Around this video, several buttons that will call different actions. When the MPMoviePlayerController is fired and the movie starts playing the buttons are behind the video and I cannot click them. I see them but they are not clickable. I think the video window is covering the whole area. How can I solve that?

• iphone - using a UISwitch

  - by Mike

  I need to implement a view where I need the user to answer several questions using YES or NO. I thought of using a UISwitch but as far as I see it does not allows replacing the ON/OFF messages it shows with YES/NO. Am I wrong? I thought of implementing a segmented control with 2 buttons but this is like using a cannon to kill a fly... Any suggestions on how to do that? thanks

• iphone - double tap fail safe way

  - by mike

  I am trying to detect double taps on a view, but when the double tap comes, the first tap triggers an action on TouchesBegan, so, before detecting a double tap a single tap is always detected first. How can I make this in a way that just detects the double tap? I cannot use OS 3.x gestures, because I have to make it compatible with old OS versions. thanks

• iphone - forcing button to acknowledge touch programmatically

  - by Mike

  When you touch a UIButton it hides for a fraction of second and then it executes its action. This fast "blink" is the feedback the user needs to know that the button has been clicked. In the project I am doing, I need to select the button programmatically, as if the user had clicked it. In other words, the same behavior has the button had been clicked by the user... a fast blink and execution of its action. Is this possible? thanks for any help.
