• iPhone OS: Posting an image + text "story" to a user's news feed through the facebook api

  - by nickthedude

  So what I am trying to do is post an image that has been created by a user on an iphone into that users newsfeed. The functionality I am having a hard time understanding if it is possible: Can I pass a local NSURL (or URL?)(to a png file that lives in the documents folder) through a JSON string and onto Facebook? i want to mimic the action of a user going to his/her facebook page, clicking into the textfield for their newsfeeld, uploading an image by clicking the "photos" icon and selecting an image from a local disk and uploading it. I would also like to add some text into the post optionally. I'm just getting started with the Facebook api and it seems pretty tough right now, any help would be appreciated. code examples appreciated. Thanks, Nick

• iPhone Push Notification Reliablity

  - by David Beck

  How reliable do you find push notification on the iPhone to be? Does it improve when moving from the sandbox to production server? I am testing (with the sandbox of course) and have found that notifications are often delayed or not received at all. I am not talking about sending multiple messages and only the last one arriving, as the documentation indicates, but any notification never showing up. Also, I noticed that if I send a notification with an alert, and then send one with just a badge number, that the second notification will close the alert even after it's already opened. Does this happen between apps as well? For instance, if I send an alert for my app, and then the Facebook app sends a badge, will the Facebook badge close my alert window?

• iPhone: Crash When Deleting UITableView Rows

  - by Ajeet Kumar Yadav

  Hi, I am new in iPhone development. I am developing an application that fetches a value from a database and displays it in a table view. I want to delete table rows one by one but the rows do not delete and the application crashes. Here is my row deletion code: - (void)tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if(editingStyle == UITableViewCellEditingStyleDelete) { SanjeevKapoorAppDelegate *appDelegate =(SanjeevKapoorAppDelegate *)[[UIApplication sharedApplication] delegate]; list *animal =[appDelegate.list1 objectAtIndex:indexPath.row]; [appDelegate deleteCoffee]; [self.tableView reloadData]; //Delete the object from the table. [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } I also delete all rows with this action: -(IBAction)deletebtn:(id)sender{ SanjeevKapoorAppDelegate *appDelegate =(SanjeevKapoorAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate deleteCoffee]; [self.tableView reloadData]; } How do I properly implement delete in an UITableView?

• iPhone CGContext: drawing two lines with two different colors

  - by phonecoddy

  I am having some troubles using the CGContext with an iPhone app. I am trying to draw several lines with different colors, but all the lines always end up having to color, which was used last. I tried several approaches I could think of, but haven't been lucky. I set up a small sample project to deal with that issue. This is my code, I use in the drawRect method. I am trying to draw a red and a blue line: - (void)drawRect:(CGRect)rect{ NSLog(@"drawrect!"); CGContextRef bluecontext = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(bluecontext, 2.0); CGContextSetStrokeColorWithColor(bluecontext, [UIColor blueColor].CGColor); CGContextMoveToPoint(bluecontext, 1, 1); CGContextAddLineToPoint(bluecontext, 100, 100); CGContextSetStrokeColorWithColor(bluecontext, [UIColor redColor].CGColor); CGContextAddLineToPoint(bluecontext, 200, 100); CGContextStrokePath(bluecontext); } thanks for your help

• iPhone OS: Rotate just the button images, not the views

  - by Jongsma

  Hi, I am developing an iPad application which is basically a big drawing canvas with a couple of button at the side. (Doesn't sound very original, does it? :P) No matter how the user holds the device, the canvas should remain in place and should not be rotated. The simplest way to achieve this would be to support just one orientation. However, I would like the images on the buttons to rotate (like in the iPhone camera app) when the device is rotated. UIPopoverControllers should also use the users current orientation (and not appear sideways). What is the best way to achieve this? (I figured I could rotate the canvas back into place with an affineTransform, but I don't think it is ideal.) Thanks in advance!

• iphone - Can't uninstall app on device

  - by wallou

  hey guys, I am testing my app on my jailbreaked iPhone and i noticed something strange. When i want to uninstall it on device i got no cross to delete the app. All the other apps (not mines) have the white circled cross. Whereas on the simulator i am able to delete my app. Is it because i run it on a jailbreak with a codesign workaround? Or maybe i am missing something in the app plist. Let me know if you have a clue. Wallou

• How can an animator do animation targeted for the iPhone

  - by teepusink

  Hi, I'm working with an animator for the iPhone. The animator I'm working with isn't a programmer and has a background in Flash. (right now she's doing the animation in Flash and I need to convert to Objective C). For some it's ok because I can just use image frames, but there are more complex animation that would take longer for me to convert to Objective C. Is there any tools out there that can help the work flow easier? Just trying to find a way so I can just take the animation and stick it into the project. Thanks, Tee

• iPhone: Setup static content of UITableView

  - by Martin

  This guide from apple https://developer.apple.com/iphone/prerelease/library/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html (you need login) explains how to use "The Technique for Static Row Content" to use Interface Builder to setup the cells in a tableview. I have some cells with different heights in my tableview. Without using the heightForRowAtIndexPath method everything get messed up. Do I still need to use this method or can I in some way setup the height of the cells inside the IB as I created them there? Also when using the "The Technique for Static Row Content" from the guide you still need to use the cellForRowAtIndexPath to setup the cells even if they are created in IB. I would like to setup the full layout of the tableview with all cells in IB (drag the cells right into the tableview), is that possible in some way? Thanks!

• Is OpenGL required for my iPhone game?

  - by Ben X Tan

  On an iPhone: If I am writing a game that has multiple levels, with multiple animations (image sequences), jpg and png (transparent), some full screen and some not, some looped and some played once only. What is the best way of doing it? Each level might have up to 10MB of images. Add on to this music, and video (cut scenes). All 2D graphics, no 3D models. Is OpenGL required? Or can this be achieved with Quartz or Core Animation?

• Iphone - Displaying NSDate values in the debugger with local timezone

  - by Oliver

  Hello, I'm trying to debug my app and there is something very annoying in the debugger : all the NSDate values are displayed in the GMT timezone. So in my debugging process, I lose a lot of time converting by myself all the displayed dates to check if they are correct in the system timezone. As I have a lot of dates at midnight, even the day is displayed "wrong". It's a nightmare. Is there a way to make the debugger display the NSDate values in the iPhone system timezone (not the MacOS one nor GMT) ? I'm at GMT+1 Thank you for your help.

• I can't use dashes in XPATH on iphone using libxml2

  - by user249488

  I'm trying to parse HTML data using KissXML for iphone. I've noticed that I can't have dashes in the id() tag, otherwise it won't evaluate. For example, if I'm trying to get the element at I would do id("foo") However, if I try to get at element , and I try id("foo-bar") the libxml2 XPATH engine doesn't seem to return anything. It works using the XPATH check for firefox, though. Anyone run into this issue and know of a reason why it's happening or have a workaround (besides using the absolute XPATH path?)

• Optimizing an iphone app for 3G in landscape with opengl, camera, quartz

  - by Joey

  I have an iphone app that basically uses the camera, an opengl layer, and UIViews (some drawing with Quartz). It runs ok on 3GS, but on the 3G it is unusable. Particularly, when I press a UIButton, it literally takes sometimes 10 seconds to register the press. Shark doesn't do me much good because it crashes when I try to profile even a tiny portion, and I've tried turning off some of the layers to see if they might be obvious contributors to the lag. I've noticed that turning off the camera really helps. I'm wondering if anyone has any familiarity with this and might suggest some likely causes. I had issues with extreme slowdown from running my app in landscape mode and using transforms, so considered that might be a cause, but I'm wondering if hoping for a 3G to run something with all of the above elements is just not really possible considering the camera seems to really cost a lot. The fact that the buttons are horribly delayed in their response makes me think there is something fundamental that I might be missing.

• Common, reusable iPhone-App configuration screen

  - by Janey

  I'm writing code that will allow my iphone-app to have a "configuration page". A grouped, scrolling, UITableView... with cells that contain the needed textFields, switches, sliders, etc. It is an ENOURMOUS amount of code. Is there an easier way? Is there a way I could create a simple text-file, contain all my desired design choices and have my (reusable) code build the TableView for me? Or... can I just do the whole thing quicker/easier in Interface Builder instead of code?

• iphone refresh images UIImageView

  - by Rick

  I have a rather basic question. I have several(5) UIImageView images on my screen. When I click a button, I want to change each image to something else. I also want to play a sound as each image is changed. So I basically want a clicking sound as each image changes. The problem is, for some reason if I have say 5 images, the sound gets played 5 times first and then the images change. It's like the images only refresh when control goes back to the user for input. How can I "force" it to refresh the images as soon as i tell it what image to display? I'm new to the iphone/macworld, so go easy on me :-) Rick

• iPhone/ObjC - How to create a custom keyboard

  - by HM1

  Hi, iPhone/objC question: How do I go about creating a custom keyboard/keypad that will show up when some one taps on a UITextField? I would like to display a keypad with a, b, c, 1, 2, 3 and an enter button, nothing else. The keypad should work and behave like the standard keyboard does (in behavior) but it will definitely look different. I can't find any example and the best I've found is to filter characters with existing keyboard which is an unacceptable solution. Thanks in advance, Hiren.

• Get a random name and number (same contact) from an iPhone users address book

  - by Sam Jarman

  Hi there, I have had only very little experience using the address book in the iPhone SDK. Does anyone have a code snippet or knows the code to get a persons name and number Eg 'Fred Smith - 027 292 2112". I haven't had much luck with the stuff I've tried. I want to achieve this programmatically, and not let the user decide (random pick of the person). I also don't want to display the contact picker either any tutorial links, or anything would be appreciated. Thanks in advance Sam

• Animating UIImageView iPhone

  - by Fred Dpn

  Hi, i'm having trouble about animating an Image in a UIImageView. I've created an image view in interface builder and linked it to its iboutlet. Here is my code. @interface Game : UIViewController <UIAccelerometerDelegate>{ IBOutlet UIImageView *diying; } @property (nonatomic, retain) UIImageView *diying; In the viewDidLoad method i've written this code NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Die1.gif"], [UIImage imageNamed:@"Die2.gif"], [UIImage imageNamed:@"Die3.gif"], [UIImage imageNamed:@"Die4.gif"], nil]; diying.animationImages = imageArray; diying.animationDuration = 1.1; diying.contentMode = UIViewContentModeBottomLeft; [diying startAnimating]; [super viewDidLoad]; which is a adaptation of what i've found here : http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/ NB : those .gif files are simple images and are not animated. I did the tutorial and it worked fine but i can't figure out why it my adaptation doesn't work !

• Can I animate a radial gradient in iPhone?

  - by user364782

  I would like to animate a radial gradient to shrink and grow the inner radius, as if it were pulsing. Right now I'm rendering the gradient with CGGradient, but I'm not sure how to animate it. I've seen this topic http://stackoverflow.com/questions/1819311/can-you-animate-gradients-using-quartz-in-an-iphone Which explains how animate a linear gradient with CAGradientLayer, but it doesn't seem like this will draw a radial gradient. Is there an easy way to animate a CGGradient, or some way to create a radial gradient CAGradientLayer? Any thoughts are appreciated.

• Does UIActivityIndicator require manual threading on iPhone

  - by Akusete

  I am running creating an iPhone application which performs a costly operation and I wanted to create an activityIndicator to let the user know the application has not frozen. The operation is performed entirely in one event call... so there is no chance for the UI framework to receive control to actually display and animate this indicator. The sample apps which use the UIActivityIndicator (or any other similar animation) start and stop the animation in different events, triggered separately at different stages of the program. Do I need to manually create a separate thread to run my operation in, or is there already default support for this kind of behavior?
