  • iPhone SDK: Downloading large files from a server into the app's documents.

    - by Jessica
    Hi, I am building an app that plays multiple video files, But I would like to know How do you download a video file (100mb - 300mb) from a server into the application's documents so it can later be locally referred to in code? The reason I want this type of a set up in my app is that I don't want the app binary to be made unnecessarily large due to including videos some users may not want. Also does this violate any of apple's terms? Also would it be simple to implement a progress view with this kind of set up and if so how? Any help is appreciated.

  • Adding a Image to UITable View Cell

    - by Graeme
    Hi, I have a table in which I want a dynamic image to load in at the left-hand side. The table needs to use an IF statement to select the appropriate image from the "Resources" folder, and needs to be based upon [dog types]. The [dog types] is extracted from an RSS feed, and so the image in the table cell needs to match the each cell's [dog types] tag. I suspect I need to use - (UIImage *)imageForTypes:(NSString *)types { to do such a thing. Thanks.

  • Sending / Forwarding variable arguments in ObjectiveC

    - by Authman Apatira
    I know this is possible in other programming languages. Suppose we have the following arrangement: - (void) myMethod:(NSString*)variables, ... { // Handle business here. } - (void) anotherMethod:(NSString*)variables, ... { // We want to pass these variable arguments for handling [self myMethod:variables, ...]; // Do not pass GO } // Start the party: [self anotherMethod:@"arg1", @"arg2", @"arg3", @"arg4", nil]; What's the trick to get this working in ObjC?

  • What is the difference between these two ways of creating NSStrings?

    - by adame
    NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

  • Does the iPhone 3G/3Gs camera put metadata in its images? (and how do you get it?)

    - by Ben Collins
    I've been trying to figure how whether the iPhone (either 3G or 3Gs) camera puts metadata into it's images. Anecdotally, it appears that it does (e.g., I've seen images posted on the web that included a bunch of metadata), but I can't find reference to it anywhere in the SDK documentation. So....does anyone have a definitive answer? Also, if there is metadata, how do I get at it?

  • comparison between point and integer

    - by LawVS
    Right, basically I want to add two numbers together. It's for a working hours calculator and I've included parameters for a night shift scenario as an if statement. However, it now mucks up the day shift pattern. So I want to sort out that if the start time is below 12, then it'll revert to the original equation shown in the code instead of the if statement. -(IBAction)done:(id)sender { int result = [finishHours.text intValue] - [startHours.text intValue]; totalHours.text = [NSString stringWithFormat:@"%d", result]; if (result < 0) { totalHours.text = [NSString stringWithFormat:@"%d", result * -1]; } if (result < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result + 24]; } if (startHours < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result - 24]; }

  • Forcing Reload of View when returning from FlipSideView of Utility Application

    - by Chris McCall
    I've got a Utility Application for iPhone 3.1.3. I have my main view loading fine. I flip over to the flipside view of the utility app and change some settings. How can I call the code I've currently got in viewDidLoad in the main view to refresh it, as settings have changed? Do I create a public method and call it from the viewDidUnload method of the flipside view? Do I call viewDidLoad directly? What's the best way to do this?

  • XCode - Automatically add all files in a folder to a target

    - by Akshay
    In XCode, is there a way to specify that all files in a folder are compiled by a target. Eg. the 'Test' target automatically compiles all files in the 'Tests' folder, whereas the 'App' target compiles everything in the 'Sources' folder. Today, the way I'm doing it, is to add a file to a target everytime I create it. This feels a bit error prone and redundant since the files are already organized in the correct folders. Thanks.

  • CALayer Position Contents to Bottom Left

    - by Louis
    I am attempting to draw an image onto a CALayer. I only need an image, so I have created my later as follows: CALayer *layer = [CALayer layer]; I add my image as follows: NSImage *img = [[NSImage alloc] initWithContentsOfFile:@"path/to/img.png"]; [layer setContents:img]; This works, however it draws my images to fill the entire parent frame (stretching my image in the process). Reading the docs, I found the following: [layer setContentsGravity:@"kCAGravityBottomLeft"]; I am attempting to draw my image in the bottom left of the parent frame, however no matter what I do it draws my icon in the bottom center. Is there anyway to specify the bottom left?

  • Content Alignment Issue in UITableView cell

    - by OhhMee
    Please see the image attached. I don't understand why it's going outside. I've also attached code snippet for tableView. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; // cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; } // Configure the cell. hNode* dCell = [array objectAtIndex:[indexPath row]]; cell.textLabel.text = @"Message"; cell.detailTextLabel.text = [NSString stringWithFormat:@"%@",[dCell contents]]; cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap; cell.detailTextLabel.numberOfLines = 0; [[cell imageView] setImage:[UIImage imageNamed:@"user.png"]]; return cell; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath { return 60; } Where could be the issue?

  • Language restrictions on iPhone lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.
