    Does anyone have a snippet that uses the AudioToolBox framework that can be used to play a short sound? I would be grateful if you shared it with me and the rest of the community. Everywhere else I have looked doesn't seem to be too clear with their code. Thanks!

  • Drawing CGPathRef in ScrollView using Iphone sdk.

    - by Ann
    Hi all. I want to draw some curve in my scroll view using CGPathRef. I tried to draw this path but i see only the part of my CGPathRef which located at 320x480 pixels. Is it way to do that. Thank you in advance. Here is my code path = CGPathCreateMutable(); CGContextBeginPath(ctx); CGContextMoveToPoint(ctx, [[pathArray objectAtIndex:0]CGPointValue].x,[[pathArray objectAtIndex:0]CGPointValue].y ); for(int i = 1; i < [pathArray count]; ++i) { CGContextAddLineToPoint(ctx, [[pathArray objectAtIndex:i]CGPointValue].x, [[pathArray objectAtIndex:i]CGPointValue].y); } CGContextClosePath(ctx); CGContextSetRGBFillColor(ctx, 0.5, 0.3, 0.2, 0.5); CGContextFillPath(ctx); And when I scroll my view the line does not change its location. My goal is to move this line during scrolling.

  • Taking video from video camera and displaying it with MPMoviePlayerController IPhone SDK

    - by Daniel
    Has anyone tried taking a video from the camera and then using the video player provided to play it? When you take the video in portrait mode, sometimes the movie will play (when the player puts it in landscape mode) and when it puts it in portrait mode you cannot view the movie all you hear is sound,sometimes in landscape mode is flickers and does not play right, has anyone encountered this and found a way to fix it? My code to play the video looks like this: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *urls=[info objectForKey:@"UIImagePickerControllerMediaURL"] ; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[info urls]]; if (moviePlayer) { [moviePlayer play]; } } I checked settings on the docs nothing seems like it would fix this...Thanks

  • Obtaining the tropicity of an image on the iPhone

    - by WhiteTiger
    Hello all I was wondering how it's possible to find out if an image in the iPhone photo library is isotropic or anisotropic. Basically how many millimeters each pixel measures in height and in width. In JPG images the information is hardcoded into the data stream so it's possible to do by simply pointing a const char* to the image file, but I'm not sure I can do that with the data the iPhone image returns. Thank you in advance

  • Need help regarding internationalization of iPhone application

    - by Taufeeq Ahmed
    I have provided support for two languages, English and Chinese, in my iPhone application. I use string files for the languages using "key"-"value" pairs and my application displays the appropriate language using NSLocalizedString(@"Fund red not red?", @""). I get only Chinese text when I run the app in XCode. How can I switch to different languages in XCode (iPhone simulator)?

    I have a PHP file with the following content that works perfectly on development ceritficates, but when I switch to a production certificate the PHP errors and gives the below message, but it only does this about 50% of the time. The other 50% it works.

  • iPhone sdk, at dismissModalViewcontrollerAnimated, the parent change y origin coordinate

    - by DigitalVanilla
    Hi guys, my first post here :) I'm having a small trouble with a small but boring problem. I have a view, with a NavigationController. I load in the NC a simple view. Inside this view there's abutton where I fire the presentModalView... in the main view, not on NC, but it's parent view: ABVIEW NC NEWVIEW new attach a presentModalView... on ABVIEW, so [abview present...]; No problem till now. When it's the time to dismiss, after the temporary window (let's calls it NOTES) disappear, my ABVIEW with all the subviews change Y position from 0 to 20, the same height of the status bar. I was looking everywhere and I'm sure it's a stupid thing, but I miss a bit of knowledge here and I have no idea where to find the solution. thanks in advance!

  • iPhone SDK background thread image loading problem

    - by retailevolved
    I have created a grid view that displays six "cells" of content. In each cell, an image is loaded from the web. There are a multiple pages of this grid (the user moves through them by swiping up / down to see the next set of cells). Each cell has its own view controller. When these view controllers load, they use an ImageLoader class that I made to load and display an image. These view controllers implement an ImageLoaderDelegate that has a single method that gets called when the image is finished loading. ImageLoader does its work on a background thread and then simply notifies its delegate when it is done loading, passing the image to the delegate method. Trouble is that if the user moves on to the next page of grid content before the image has finished loading (releasing the GridCellViewControllers that use the ImageLoaders), the app crashes. I suspect that this is because along the line, an asynchronous method finishes and attempts to notify its delegate but can't because it's been released. Here's some code to give a better picture: GridCellViewController.m: - (void)viewDidLoad { [super viewDidLoad]; // ImageLoader _loader = [[ProductImageLoader alloc] init]; _loader.delegate = self; if(_boundObject) [_loader loadImageForProduct:_boundObject]; } //ImageLoaderDelegate method - (void) imageDidFinishLoading: (UIImage *)image { [_imgController setImage:image]; } ProductImageLoader.m - (void) loadImageForProduct: (Product *) product { // Get image on another thread [NSThread detachNewThreadSelector:@selector(getImageForProductInBackground:) toTarget:self withObject:product]; } - (void) getImageForProductInBackground: (Product *) product { NSAutoreleasePool *tempPool = [[NSAutoreleasePool alloc] init]; HttpRequestLoader *tempLoader = [[HttpRequestLoader alloc] init]; NSURL *tempUrl = [product getImageUrl]; NSData *imageData = tempUrl ? [tempLoader loadSynchronousDataFromAddress:[tempUrl absoluteString]] : nil; UIImage *image = [[UIImage alloc] initWithData:imageData]; [tempPool release]; if(delegate) [delegate imageDidFinishLoading:image]; } The app crashes with EXC_BAD_ACCESS. Disclaimer: The code has been slightly modified to focus on the issue at hand.
