  • MPMoviePlayerController problem at start

    - by Infinity
    Hello guys! I have a problem with MPMoviePlayerController, because when I start it in fullscreen it exists, but the song is still playing. I added the MPMoviePlayerDidExitFullscreenNotification notification and it says that when the video starts playin it exists the full screen. Here's my code: _multimediaPlayer = [[MPMoviePlayerController alloc] init]; _multimediaPlayer.controlStyle = MPMovieControlStyleDefault; _multimediaPlayer.initialPlaybackTime = 0; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayerDidExitFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayerPlaybackStateChanged:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil]; NSString *path = [NSString stringWithFormat:@"%@/mag_%d/%@", [FMUtils documentsFolderPathWithFile:nil], _magID, _pageObject.fileName]; if ([FMUtils fileExistsAtPath:path]) { _multimediaPlayer.contentURL = [NSURL fileURLWithPath:path]; } else { _multimediaPlayer.contentURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", self.dataURL, _pageObject.fileName]]; } CGSize objectViewSize = self.frame.size; _multimediaPlayer.view.frame = CGRectMake(0, 0, objectViewSize.width, objectViewSize.height); [self addSubview:_multimediaPlayer.view]; if (_pageObject.blink) { [_multimediaPlayer setFullscreen:YES animated:YES]; } [_multimediaPlayer play]; Most of the time it happens when the video is not downloaded and it needs to stream it. Do you have any idea why is this happen?

  • Audio queue start failed

    - by mobapps99
    Hi , i'm developing a project which has both audio streaming and playing audio from file. For audio streaming i'm using AudioStreamer and for playing from file i'm using avaudioplayer. Both streaming and playing works perfectly as long as the app is not interrupted by a phone call or sms. But when a call/sms comes after dismissing the call when i try to restart streaming i'm getting the error "Audio queue start failed" . This happens only when i have used avaudioplayer at least once and after that used streaming. When the avaudioplayer obeject is not created , in this scenario the there is no problem with resuming streaming after dismissing the call. My guess is that some thing is wrong with audioqueue. Help is very much appreciated.......

  • Why are my CATransitions acting up?

    - by Regan
    I am using the following code to switch between views with CATransition. CATransition *applicationLoadViewIn = [CATransition animation]; [applicationLoadViewIn setDuration:20]; [applicationLoadViewIn setType:kCATransitionPush]; [applicationLoadViewIn setSubtype:kCATransitionFromTop]; [applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]]; ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init]; [self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush]; [self.view addSubview:myviewcontroller.view]; It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity. What is going on here?

  • Problem with saveToFile

    - by zp26
    Hi, I have a problem with a NSData writeToFile. I have implemented the code below but i have an anomaly. When i run my program on the simulator, the new file is created and the informations are stored; when i build the app in my device , the file isn't created. The debug don't give me any error but don/t save anything. Can you help me? Thanks so much and sorry for my english. -(void)saveXML:(NSString*)name:(float)x:(float)y:(float)z{ NSMutableData *data = [NSMutableData data]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver setOutputFormat:NSPropertyListXMLFormat_v1_0]; [archiver encodeFloat:x forKey:@"x"]; [archiver encodeFloat:y forKey:@"y"]; [archiver encodeFloat:z forKey:@"z"]; [archiver encodeObject:name forKey:@"name"]; [archiver finishEncoding]; BOOL result = [data writeToFile:@"XML Position" atomically:YES]; if(result) [self updateTextView:@"success"]; [archiver release]; }

  • Any way to trigger interface orientation check?

    - by Johnny Tee
    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

  • Drawing Mirrored Text

    - by Jeff
    I'm trying to draw mirrored (as in, it looks like you held it up to a mirror) text, and I want to do it the easiest way possible. It is possible to do a transform on a UILabel? Or do I have to use Quartz and do CGContextShowTextAtPoint() ?

  • Will pool the connection help threading in sqlite (and how)?

    - by mamcx
    I currently use a singleton to acces my database (see related question) but now when try to add some background processing everything fall apart. I read the sqlite docs and found that sqlite could work thread-safe, but each thread must have their own db connection. I try using egodatabase that promise a sqlite wrapper with thread safety but is very buggy, so I return to my old FMDB library I start to see how use it in multi-thread way. Because I have all code with the idea of singleton, change everything will be expensive (and a lot of open/close connections could become slow), so I wonder if, as the sqlite docs hint, build a pooling for each connection will help. If is the case, how make it? How know wich connection get from the pool (because 2 threads can't share the connection)? I wonder if somebody already use sqlite in multu-threading with NSOperation or similar stuff, my searching only return "yeah, its possible" but let the details to my imagination...

  • iOS App with OCMaps crashes when using the phone in chinese Language

    - by Pedro Morte Rolo
    I've been given the task of doing maintenance to a iOS application that uses OCMapView. I have just realized that when using the application in chinese language, it blows up when the selector doClustering is invoked on a OCMapView instance. This is for me a very puzzling behaviour, because I thought that regardless of the environment language, the OCMapView class should allways have the same methods. Am I wrong? Do you have any recomentations about how to find a solution to this problem? Thank you, Pedro

  • Do I need to use decimal places when using floats? Is the "f" suffix necessary?

    - by Paulo Fierro
    I've seen several examples in books and around the web where they sometimes use decimal places when declaring float values even if they are whole numbers, and sometimes using an "f" suffix. Is this necessary? For example: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1.00]; How is this different from: [UIColor colorWithRed:0.8f green:0.914f blue:0.9f alpha:1.00f]; Does the trailing "f" mean anything special? Getting rid of the trailing zeros for the alpha value works too, so it becomes: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1]; So are the decimal zeros just there to remind myself and others that the value is a float? Just one of those things that has puzzled me so any clarification is welcome :)

  • Using accelerometer to detect iPad lock switch trigger?

    - by DevDevDev
    So for complicated reasons I am managing view rotations myself, and am only implementing UIDeviceOrientationPortrait as the autorotating orientation. Anyway, when one clicks the screen lock on the iPad, the device will rotate to UIDeviceOrientationPortrait, which will cause my code to rotate, which I do not want to happen. For instance of the user is holding the device in "landscape mode", i.e. I have already manually rotated the UI to landscape mode, and he/she clicks the screen lock, it will rotate the UI to portrait mode, even though the user did not move the device at all. So somehow I need a way to differentiate between rotations to portrait mode occuring from the screen lock, and those occuring from device rotation. As such, I would like somehow to use the accelerometer to detect whether or not the device was actually 'rotated' or whether the button was clicked. Thanks!

  • How to check whether Application is Busy or not

    - by Chandan Shetty SP
    Hi, I am using "networkActivityIndicatorVisible" in UIApplication for showing network spinning gear in status bar if my WebView( I am setting "networkActivityIndicatorVisible = YES" in "webViewDidStartLoad" and reseting in "webViewDidFinishLoad" ) is busy. It works fine for single UIWebView. For Multiple UIWebViews i have used a "stack" to trace which webview is busy and which one is idle and it is working fine. My question is there is any way to know whether an application is busy or idle in application level(in UIApplication) instead of checking each webview so i can remove stack. Thanks.

  • iPad title bars. Navbars or toolbars?

    - by Squeegy
    I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

  • merging UIImagePickerController image with cameraOverlayView

    - by GameDev
    Im really in the need for some help and advice. Spent the last week on this and have now just become frustrated as i cant get it to work! Basically, im trying to merge two images into one image to display/save. First the user picks an image from album, it goes to edit image screen where user can move and scale the image. On this screen is an overlay image (320x480) for the person to align there eyes in. Once aligned I want to save this image (edited and overlay) into one and pass the image onto my next screen. It works fine when the image is filling the edit/crop box, but when the image is widescreen with top and bottom not filling the box, then when i save the image the coords of the overlay dont get saved correctly! Heres my code, ive tried various ways of doing this but have failed at every attempt :( - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the cropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // Combine image with overlay before saving!! image = [self addOverlayToImage:image]; overlayGraphicView.image = nil; // Take the picture image to the post picture view controller postPictureView = [[PostPictureViewController alloc] init:image Company:companyName withLink:buyButtonLink]; [picker pushViewController:postPictureView animated:YES]; [picker release],picker = nil; } The problem is that the image picked (originalImage) could be of any height, my overlayImage is however always 320x480, its almost all transparent with just two eye images in center which i want to save over the original images eyes! - (UIImage*) addOverlayToImage:(UIImage*)originalImage { CGRect cgRect =[[UIScreen mainScreen] bounds]; CGSize size = cgRect.size; UIGraphicsBeginImageContext(size); [originalImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* overlayImage = [UIImage imageNamed:overlayGraphicName]; [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); [finalImage retain]; UIGraphicsEndImageContext(); return finalImage; } I wish there was just an easy way to take a screenshot of whatever is in the edit crop box :( Please if someone could help me with this ASAP as I need to finish this in 1-2 days time! Thank you. EDIT:- I should also mention that with this I get the correct center of the screen and placement of the overlay on my next screen: [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; However, I am unable to work out the correct position of the main image especially as the height is different for every image if not fullscreen! I tried this to center it into the correct position but it doesnt work: [originalImage drawInRect:CGRectMake(0,(size.height/2 - originalImage.size.height/2), originalImage.size.width, originalImage.size.height)];

  • UITableView and keyboard scrolling problem

    - by Jonathan
    after a lot of trial and error, I'm giving up and asking the question. I've seen a lot of people with similar problems but can't get all the answers to work right. I have a UITableView which is composed of custom cells. The cells are made of 5 text fields next to each other (sort of like a grid). When I try to scroll and edit the cells at the bottom of the UITableView, I can't manage to get my cells properly positioned above the keyboard. I have seen many answers talking about changing view sizes,etc... but none of them has worked nicely so far. Could anybody clarify the "right" way to do this with a concrete code example? Thanks in advance, Jonathan

  • Why does presentModalViewController not always work?

    - by E-Madd
    My application requires data from a server in order to run. The first thing it does is displays a view controller (LoadingViewController) that is responsible for checking if the data is saved to my PersistentStoreCoordinator. If the data isn't cached locally, it gets it from my server and caches it, and posts a notification that the LoadingViewController is listening for. When that notification comes through, LoadingViewController presents the application's MainViewController using the presentModalViewController with a flip animation. So far, so good... no errors. However, if the application loads and determines the data IS cached - the presentModalViewController does not work and the main application view never appears. No errors. I've even gone as far as adding a button to the Loading view that executes the same code when pressed and the damn thing works. I'm suspicious it has something to do with the timing of it all but I'm clueless as to what I can do to ensure the view is displayed with that flipping animation if the data is already cached locally. Any suggestions?

  • UITextView on iPad INCREDIBLY Slow

    - by Sj
    I have an NSMutableArray of custom views (that are pretty much 1 UITextView and 1 UILabel with a custom back ground image), these are created as they are need (I start with 2 (though the first one is only 2 UITextFields and the other is normal) of these). Now my issue here seems to be this: as soon as I try to edit any UITextView past the one in the 2nd view, it starts to run incredibly slow, not the app, just the textview. For example, as I type, the little blinky guy lags behind the text and when I click to copy/paste/cut/etc you can see the little balloon fly in from the upper left corner every time. I have run the static analyzer for leaks and come up with nothing and run it alongside some other the testing software in XCode and it does not appear to have any reason for this. Any help would be greatly appreciated.
