• How to request device token on iphone

  - by Greg

  Hello, I am able to use the didRegisterForRemoteNotificationWithDeviceToken callback method to get the device token of my iphone when subscribing to push notifications. My question is how can I get this token again a later time? When a user subscribes to something in my application, I want to send the device token and the id of the item they are subscribing to...but I can't figure out where to get the device token from. I tried using the uniqueIdentifer from the UIDevice class but this value is different than what the original token was. I supposed I could call registerForRemoteNotificationTypes each time my app starts to produce the token. But if I do that, I'm not sure how I can access this value from a different class (my didRegisterForRemoteNotificationWithDeviceToken callback is located in the main application delegate). Thanks for any help for an objective C newbie!

• NSTimer to fire while device is locked

  - by edie

  Hi, I'm currently creating an alarm. I use NSTimer to schedule my alarms. My problem is when the device was put into locked mode my NSTimer doesn't fire. I think that the NSTimer will not fire because my app goes to suspended state when it is lock. Can you help me find a solution to my problem? I've found some topics about UIBackgroundModes, but I don't know how it will help me. Thanks.. The problem in UILocalNotification is when the device was in silent, the sound will not be hear. My implementation was I'm using NSTimer to fire an alarm when the app is in foreground or device is locked but app currently running. When the applicationDidEnterBackground: is called I schedule the UILocalNotification as the alarm.

  - by aviavi

  hey i have iphone application that using facebook connect. users login to the iphone application using facebook connect. and then i receive their sessionKey back to my server, and i am using the sesssionkey to post actions to users wall. the iphone application keeps the user logged in allways. which means that every times the user will open the application, he will not need to make login again. the problem is that, when the user change his facebook password the user sessionKey also changes. and when the user enter to my iphone applicaiton, the user is shown as loggedin, and then i recieve to my server the user old sessionkey, and when i try to post to the user wall facebook tells me that the session is inavlid. it is ok because the user change his password and the session changes too. my question is how can i check in the iphone if the session key has changed ? and if it changes to promote the user to make login again.

• Measuring device drivers CPU/IO utilization caused by my program

  - by Lior Kogan

  Sometimes code can utilize device drivers up to the point where the system is unresponsive. Lately I've optimized a WIN32/VC++ code which made the system almost unresponsive. The CPU usage, however, was very low. The reason was 1000's of creations and destruction of GDI objects (pens, brushes, etc.). Once I refactored the code to create all objects only once - the system became responsive again. This leads me to the question: Is there a way to measure CPU/IO usage of device drivers (GPU/disk/etc) for a given program / function / line of code?

• iPhone: Save with validation on back navigation

  - by iPhone beginner

  In my iPhone application I have navigation controller, main screen and some edit screens. On edit screen user does some input that has to be validated before I can save it. Ideally I would like to update data automatically on back navigation without additional "Done" button. Can I do some validation and save on back navigation (i.e. when user taps on standard back button) in a way that allows my to stop navigation and show some error message if something is wrong? I see several other possibilities: Create my custom left button and make it looks like standard back. (Why Apple didn't put this button style into public API?) Add "Done" button and save data only if user taps it but both these choices I like much less. So if there is a way to achieve what I want, I'd like to use it.

• iPhone 4.0 on iPhone but still Ad-Hoc compile for 3.1.3?

  - by Mark

  Device: Version : 3.1 Build: 3511 Device: iPhone OS: iPhone OS 4.0 xCode 3.2.2 (Old) xCode 3.2.3 (New; For iPhone 4.0 Beta) Background: As you can see I installed 4.0 on my iPhone as I read on this forum it's really hard to near impossible to downgrade back to 3.1.3, but it's my only device I have and use for development. When I try to continue to develop and build with the old xCode it tells me that "No provisioned iPhone OS device is connected". When I select Simulator it does compile and build, however when I spread this file it does not work on the devices of my testers, they get a Signed error. When I run the new xCode, it does compile and build on the Device and when I spread this file, it does work on the devices of my testers (which are running the current official version 3.1.3). Questions: Why is there a difference between building for Simulator and Device? A simulator build never seem to work on the devices of my testers because of signing issues and the build for device does work. Currently it seems the old xCode became useless, however I read that you may not use the Beta xCode to build your application for release. So knowing the above how am I able to pull this off with my current setup due the fact the old xCode won't let me build properly.

• Simple JPG/HTML Not Showing Up in iPhone

  - by Jascha

  I'm not familiar with iPhones wants and needs, nor do I have one, but a client wants a screen cap of his site to show up when an iPhone user comes around so I created an .htaccess redirect to an iPhone specific page with this bit of code... RewriteEngine on RewriteCond %{HTTP_USER_AGENT} iPhone RewriteCond %{REQUEST_URI} !^/iPhone/ RewriteRule .* /iPhone/ [R] And the html of the iPhone page... <html> <head> <title>Eatamadedia</title> </head> <body style="background-color:#858384;margin:0 auto;"> <img src="../images/iPhonePage.jpg"> </body> </html> The page redirects just fine, but the .jpg doesn't show up. I can't imagine a simpler page. Anyone know what could be preventing the image from displaying? Does the iPhone require headers? The site in question is http://eatamedida.com Thank you in advance for your input. -J

• Push notification not received in ios5 device

  - by Surender Rathore

  I am sending push notification on device which has iOS 5.0.1, but notification is not received on iOS5 device. If i try to send notification on iOS4.3.3 device, it received on this device.

• Making the iPhone work with stripped down Windows XP

  - by Gabriel

  Hi, this is my first time posting here and I have a really specific question. I have an ASUS eee 901 running Windows XP Home. I had everything working well, but then I decided to improve performance by moving Windows to the smaller but faster internal SSD. I used Nlite to strip down Windows, following the instructions here: http://wiki.eeeuser.com/howto:nlitexp I now have a very lightweight installation of XP home with SP3 and all the current updates. Almost everything is working really well. I have installed iTunes and I CAN sync with no problems. However, each time I plug in my iPhone 3GS (latest firmware), Windows tries and fails to install drivers. The Found New Hardware Wizard launches, but nothing I do will make it complete successfully, with the result that the iphone does not show up in Windows as removable storage, or as a camera. When I launch the Camera and Scanner Wizard, it shows only my webcam, not the iphone. I have verified that I have the following files in place: Windows\System32\ptpusb.dll (regsvr32 successful) Windows\System32\ptpusd.dll (entry point not found, can not be registered) Windows\System32\usbaaplrc.dll (entry point not found, can not be registered) Windows\System32\drivers\usbaapl.sys Windows\System32\drivers\usbscan.sys Windows\System32\drivers\usbstor.sys Does anyone know if some other file is required or if there's some other element preventing this from working? Edit (From posted answer) I did select Cameras & Camcorders, and my webcam is working fine for video & still capture.

• iPhone Remote with iTunes Library via VPN

  - by sudo work

  Alright, so I'm currently behind a network router (not under my control). The router performs NAT and somehow prevents a computer from scanning other nodes. At least, you're unable, in this instance, to locate an iTunes library. You can, however, communicate with a node's open ports if the local IP address is known, as well as the port. I haven't actually tried port scanning a specific IP using nmap or another tool yet. So I've tried one solution to remove the contribution of the router entirely (to verify that it works without the influence of the routers). I set up an access point using my iPhone and tethered my computer (with the library) to it. From here, I was able to pair my library and the iPhone Remote application. Control of the library was normal as well. This solution is not ideal, however, because I am actively using bandwidth with my computer and cannot afford to be tethered to my 3G connection. A viable solution for me is to use a common VPN connection, which I have set up on a Ubuntu (Intrepid) server that is remote. Both my computer and iPhone are able to access the VPN via PPTP. The server is setup with PPTPD as the VPN-server; I'm using IPTables to perform IP masquerading and forwarding traffic. I however, still cannot connect the library to the phone. I can however, see both devices on the VPN subnet (192.168.0.0/24). SSH'ing and such works fine. What settings on the VPN server must I change to get this to work? Also, how can I assign static IP addresses to various PPTP clients based on MAC addresses?

• How to connect to a SOCKS Proxy from an iPhone/iPod Touch?

  - by GeneQ

  I like to surf securely and privately via a SOCKS proxy which I created via SSH tunneling, on the Mac. I used the SSH client on my Mac to achieve this. Then I thought, since the iPhone OS is essentially Mac OS, the same trick might work also on the iPhone. I managed to create a SSh tunnel on my iPhone via the Terminal (iPhone's Terminal). (Yes, it's jail-broken) ssh -D [port] [email protected] At this stage my iPhone is SOCKS proxy. However, there doesn't seem to be a way in the iPhone networking preference panel to specify a SOCKS proxy. Someone suggest creating a Proxy Auto-Contig (PAC) file to workaround this, but that sounds complicated. Any ideas how to make iPhone use it's own SOCKS proxy?

• how to run apache2 or nginx + php on iPhone? [closed]

  - by Rubytastic

  Is there a way to run Apache2 or Nginx with PHP on the iPhone? Im surprised so little info is available on this topic, as it seems quite interesting to host websites on an iPhone. Consider slow 3G connections or no 3G at all, and you want to demonstrate some webapplication you wrote... hosting them on the iphone would be an awsome way to fix the speed issues with the mobile network speeds. For the Ipad there are several addoptions available, nothing much usable on iphone / nginx apache2 search terms anywhere :( I want to host some websites on my iphone for demonstration purposes. So when im "out the office" Ill be able to very fast browse some websites that I host on the Iphone. there is no decent information out there, does anyone have a lead on how to do this? My question is specific to if nginx or apache2 can be run on the iphone, it would be nice if PHP would run on it too

• What is the the best way to become an iPhone developer?

  - by Noah89

  I have no experience as a programmer but I'd like to become a iPhone developer. Some people tell me to learn java because it is a Object Oriented Language. Other people tell me to go with C++. However, everyone advises me to actually learn any language and learn what programming is all about before I actually develop for iPhone. Please, let me know what would be the best choice and what books would be good for a total beginner and any website that offers any good tutorials.

• iPhone / Objective-C: NSMutableArray writeToFile won't write to file. Always returns NO

  - by Joel

  I'm trying to serialize two NSMutableArrays of NSObjects that implement the NSCoding protocol. However it works for one (stacks) and not the other (cards). I have the following block of code: -(void) saveCards { NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString* documentsDirectory = [paths objectAtIndex:0]; NSString* cardsFile = [documentsDirectory stringByAppendingPathComponent:@"cards.state"]; NSString* stacksFile = [documentsDirectory stringByAppendingPathComponent:@"stacks.state"]; BOOL c = [rootStack.cards writeToFile:cardsFile atomically:YES]; BOOL s = [rootStack.stacks writeToFile:stacksFile atomically:YES]; } I step through this method using the debugger, and after the last two lines of code run, I check the values of the two BOOLs. BOOL c is NO and BOOL s is YES. The stacks array is actually empty (which is probably why it works). The cards array has contents. Why is it that the array with contents is failing? I can't figure this out. I've looked through numerous threads on SOF, each of them say the problem is because the protection level of the files they were writing were preventing them from writing. This is not my problem, as I'm writing to the Documents folder. I've double and tripple checked that neither rootStack.cards nor rootStack.stacks is nil. And I've checked that cards does indeed have content. Here are the coder methods for my Notecard class (I added all the if statments as part of trying to solve this problem to make sure trying to encode nil values doesn't break something): -(void) encodeWithCoder:(NSCoder *)encoder { if(text) [encoder encodeObject:text forKey:@"text"]; if(backText) [encoder encodeObject:backText forKey:@"backText"]; if(x) [encoder encodeObject:x forKey:@"x"]; if(y) [encoder encodeObject:y forKey:@"y"]; if(width) [encoder encodeObject:width forKey:@"width"]; if(height) [encoder encodeObject:height forKey:@"height"]; if(timeCreated) [encoder encodeObject:timeCreated forKey:@"timeCreated"]; if(audioManagerTicket) [encoder encodeObject:audioManagerTicket forKey:@"audioManagerTicket"]; if(backgroundColor) [encoder encodeObject:backgroundColor forKey:@"backgroundColor"]; } -(id) initWithCoder:(NSCoder *)decoder { self = [super init]; if(!self) return nil; self.text = [decoder decodeObjectForKey:@"text"]; self.backText = [decoder decodeObjectForKey:@"backText"]; self.x = [decoder decodeObjectForKey:@"x"]; self.y = [decoder decodeObjectForKey:@"y"]; self.width = [decoder decodeObjectForKey:@"width"]; self.height = [decoder decodeObjectForKey:@"height"]; self.timeCreated = [decoder decodeObjectForKey:@"timeCreated"]; self.audioManagerTicket = [decoder decodeObjectForKey:@"audioManagerTicket"]; self.backgroundColor = [decoder decodeObjectForKey:@"backgroundColor"]; return self; } each field is either an NSString, NSNumber, or UIColor. Thanks for any help

• Custom UIViewController is not responsive to device rotation

  - by Wayne Lo

  I have a custom UIViewController, which is the only subView of UIView. The UIViewController contains delegate function: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } This function is called once when the application starts and is never called again when the device is rotated. I also notice that the willRotateToInterfaceOrientation function is never called. I pretty much commented out all the content in the UIViewController but it is still not responding to device rotation.

• iPhone MFMailComposeViewController's "cancel" button displays Action Sheet w/ incorrect orientation.

  - by user211790

  I've been trying to add in-app email functionality and have been somewhat successful. The MailCompose view is displayed properly. But when "Cancel" is pressed the Action Sheet with "Delete", "Save as Draft" and "Cancel" animates in from the left as if the view controller is set to portrait mode*, yet the width (or height depending on how you look at it) is that of an action sheet in landscape mode as seen in the following image: http://dansandland.com/storage/screen-shot-2.png *The view controller is set to Landscape Left, both in the plist file and the shouldAutorotateToInterfaceOrientation method of all view controllers. MFMailComposeViewController code in a view controller: MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init]; controller.mailComposeDelegate = self; [controller setSubject:@"In app email..."]; [controller setMessageBody:@"...email body." isHTML:NO]; [self presentModalViewController:controller animated:YES]; [controller release]; Any ideas?

• How do I break down an NSTimeInterval into year, months, days, hours, minutes and seconds on iPhone?

  - by willc2

  I have a time interval that spans years and I want all the time components from year down to seconds. My first thought is to integer divide the time interval by seconds in a year, subtract that from a running total of seconds, divide that by seconds in a month, subtract that from the running total and so on. That just seems convoluted and I've read that whenever you are doing something that looks convoluted, there is probably a built-in method. Is there? I integrated Alex's 2nd method into my code. It's in a method called by a UIDatePicker in my interface. NSDate *now = [NSDate date]; NSDate *then = self.datePicker.date; NSTimeInterval howLong = [now timeIntervalSinceDate:then]; NSDate *date = [NSDate dateWithTimeIntervalSince1970:howLong]; NSString *dateStr = [date description]; const char *dateStrPtr = [dateStr UTF8String]; int year, month, day, hour, minute, sec; sscanf(dateStrPtr, "%d-%d-%d %d:%d:%d", &year, &month, &day, &hour, &minute, &sec); year -= 1970; NSLog(@"%d years\n%d months\n%d days\n%d hours\n%d minutes\n%d seconds", year, month, day, hour, minute, sec); When I set the date picker to a date 1 year and 1 day in the past, I get: 1 years 1 months 1 days 16 hours 0 minutes 20 seconds which is 1 month and 16 hours off. If I set the date picker to 1 day in the past, I am off by the same amount. Update: I have an app that calculates your age in years, given your birthday (set from a UIDatePicker), yet it was often off. This proves there was an inaccuracy, but I can't figure out where it comes from, can you?

• Objective-C iPhone - NSMutableArray addobject becomes immediately out of scope.

  - by Robert

  ok. I have a really odd and mind boggling problem. I have two class files, both of which are NSObject inheritors. The series of code is as follows CustomClass *obj; obj = [[CustomClass alloc] init]; [myArray addObject:obj]; <--------Immediately after this line if I hover over the array it shows it as having 1 object that is out of scope. If I hover over both objects they both have what look to be initialized memory locations so I really have no idea what is going on here. Thanks in advance.

• iPhone SDK: How to centre content in a UIScrollView during setZoomScale?

  - by Russell Quinn

  I'm using a UIScrollView to show photos. If they are zoomed out so they are smaller than the scroll view in one dimension then the content is centred using contentInset and contentOffset. This all works fine for scrolling and manual zooming. However, if I use setZoomScale (with animated YES) then when zooming out the scroll view sets the top left edge to 0,0 during the animation and then snaps it back afterwards. It seems like the zoom animation ignores the contentInset and contentOffset settings. Does anyone have any idea how to overcome this problem? Thanks, Russell.

• does the accelerometer work for the iphone/ipad simulator?

  - by Mark

  From what I can tell, my app should be firing accelerometer events while Im using the iPad simulator in XCode, but its not. I have googled around and it somewhat seems that the accelerometer is not implemented in the simulator, is this correct? If so, why on earth would they have a "Hardware-Shake Gesture" menu option? My code is as follows: .h file: @interface MyViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate, UIAccelerometerDelegate>{ UIAccelerometer *accelerometer; //...other stuff } @property (nonatomic, retain) UIAccelerometer *accelerometer; @end then the .m file: @implementation MyViewController @synthesize accelerometer; - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration { NSLog(@"%@", [NSString stringWithFormat:@"%@%f", @"X: ", acceleration.x]); NSLog(@"%@", [NSString stringWithFormat:@"%@%f", @"Y: ", acceleration.y]); NSLog(@"%@", [NSString stringWithFormat:@"%@%f", @"Z: ", acceleration.z]); } - (void)viewDidLoad { [super viewDidLoad]; self.accelerometer = [UIAccelerometer sharedAccelerometer]; self.accelerometer.updateInterval = .1; self.accelerometer.delegate = self; } @end Does this look right?

• Is there a Queue/FIFO data structure for the iPhone?
