• current location too slow for view

  - by Christian

  Hi, I make an App with a Map in the App and a button to change to the google.Map-App. The code for my position is: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { float avgAccuracy = (newLocation.verticalAccuracy + newLocation.horizontalAccuracy)/2.0; if (avgAccuracy < 500) { [locationManager stopUpdatingLocation]; locationManager.delegate = nil; } storedLocation = [newLocation coordinate]; The code for the view is: - (void)viewDidLoad { [super viewDidLoad]; UIImage *image = [UIImage imageNamed: @"LogoNavBar.png"]; UIImageView *imageview = [[UIImageView alloc] initWithImage: image]; UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView: imageview]; self.navigationItem.rightBarButtonItem = button; [imageview release]; [button release]; locationManager=[[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = kCLDistanceFilterNone; [locationManager startUpdatingLocation]; mapView.showsUserLocation = YES; NSLog(@"storedLocation-latitude für MKregion: %f", storedLocation.latitude); MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE]; MKCoordinateRegion hotel; hotel.center.latitude = 45.58058; hotel.center.longitude = -0.546835; HotelPositionMarker* marker = [[HotelPositionMarker alloc] initWithCoordinate:hotel.center]; [mapView addAnnotation:marker]; [marker release]; } My problem: when the "viewDidLoad" start, the "storedLocation" is still 0.0000 it takes a bit longer to get the own position than to start the view. The Log for the "storedLocation" in the "viewDidLoad"-section is 0 while the Log of the "storedLocation" in the "-(IBAction)" when the map is visible contains the right values. How can I manage it to have my coordinates before the view load? I need them to center the view concerning the own position and the position given by me. MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE];

• Iphone contact photo

  - by Kiran

  I tried to search an answer for this but couldn't find one. My iPhone application needs to access the Photo associated with the contact in the phonebook. However, it also needs to make sure that every time application is launched, it verifies that the photo is the same. So, in essence, I am trying to access the photo used by contacts database for a person's phone number or email address. - Is there a way for me to do this? Any help is appreciated.

• How can I create a button with a UIActivityIndicator in my navigation bar with the same style as nor

  - by Jarin Udom

  All of the examples I've seen on here and other sites involved creating a UIActivityIndicatorView and loading it with something like: self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:myActivityIndicatorView target:nil action:nil] autorelease]; However, that just creates a plain activity indicator in the navigation bar. What I want to do is have a button that looks just like the normal UIBarButtonSystemItem buttons but with an activity indicator instead of one of the default images. I've tried doing initWithImage and initWithTitle with nil images or titles and then adding the activity indicator as a subview, but that doesn't work. Any ideas?

• Line breaks in "NSString"s returned from PList don't work.

  - by Moshe

  I've seen this post: http://stackoverflow.com/questions/2035567/nsstring-newline-escape-in-plist but I'd like to know if there's a way to pragmatically render \n line breaks. I'm currently using: decisionText.text = [NSString stringWithFormat: (@"%@", [replies objectAtIndex:(arc4random() % [replies count])])]; Which randomly grabs a String from the replies array. The array was loaded from a plist like so: replies = [[NSMutableArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"AdviceList" ofType:@"plist"]]; What am I missing? The answer can't be to manually enter line breaks. That's not programming! (Sounds like word processing to me.)

• Who should call viewDidLoad on progammatically loaded views?

  - by Remus Rusanu

  When I need to load a view programatically I do the following: MyController* myController = [[MyController alloc] init]; [[NSBundle mainBundle] loadNibNamed:@"myNib" owner:myController options:nil]; // use my controller here, eg. push it in the nav controller This works fine, but my controller's viewDidLoad is never called. So I resorted to manually calling it after the loadNibNamed call, but it doesn't seem correct. I was expecting the framework to call the viewDidLoad on my behalf. Is this the right way or I'm missing something?

• Releasing an app - Developed on one account, releasing/approving on another

  - by stumac85

  Hi there, We have developed an application for a company who want to release it under their own account. It has been developed on our account and has had provisioning profiles attached to it from our own account. What is the best way to do this? Do I have to send them the xCode project and talk them through how to attack a provisioning profile to the project? Or can I just get their login details and create a provisioning profile from the Mac in the office and do it for them? Or is there a "transfer to different account" option? Many thanks!

• How can I use images provided by the iPhone OS?

  - by Topher Fangio

  Hello all, First, let me state what brought this question about: I saw the green checkmark icon in this post and I would like to use it in my own application. However, since it looks so much like the UITableViewCellAccessoryDetailDisclosureButton my assumption is that this green checkmark icon is provided by the iPhone OS in some form or fashion. So, my question is: how can I use the green checkmark icon and/or other OS-provided images in my own applications? As a side question: where can I find a list of the OS-provided images (if they even exist)? Thanks very much for any input :-)

• Anyone knows of a good addressbook implementation?

  - by Tsahi Levent-Levi

  I am looking to add an address book to one of my programs. For that purpose, I want to have something that is flexible and customizable to the point of allowing me to hook up additional metadata to contacts in it from third parties. I don't mind paying for a solution as long as I get something that is usable for me. My requirements: Optimized to run on embedded devices Preferably in source code form Ability to add my own fields to contacts over those the address book provides out of the box Ability to plugin "stuff" to it to enhance it without changing its base code too much Has a C or C++ interface

• Producer Consumer Issue with Core Data

  - by Mugunth Kumar

  I've a Core Data application. In the producer thread, I pull data from a web service and store it in my object and call save. My consumer object is a table view controller that displays the same. However, the app crashes and I get NSFetchedResultsController Error: expected to find object (entity: FeedEntry; id: 0xf46f40 ; data: ) in section (null) for deletion on the console. When I debug it, everything works fine. So I understood that it's like a race issue. How is these kind of problem solved? What's the best way to design a producer-consumer app with core-data?

• Stop Images from loading in UIWebView

  - by Zac Altman

  I have a website that I wish to load in a UIWebView, but it is full of images and takes ages to load. The images are useless, and only serve to reduce the usability on the iPhone. I dont own the website so I cannot change the site's actual code. The webpage is heavily linked in to the web with ASP.NET and AJAX (needs external files), so i dont think it is possible to have it load an HTML string. I want to stop the images from loading altogether. So how do i block them? Change the HTML code as its loading somehow, or block images from being loaded?

• Why dont Android applications provide an "Exit" option?

  - by Howiecamp

  Is there something in the Android developer guidelines that disuadea developers from providing the option to "exit" (stop running) an application from within the application itself? I love multitasking and all but it's not clear to me why: the vast majority of apps don't have their own Exit functions and hence just keep running forever don't give you a choice about running when you turn on the phone - they just do by default Both of these things lead to memory usage constantly increasing and your device running with this performance burden all of the time despite the fact that you may only want certain apps to run some of the time. Am I missing something?

• Calling method on category included from iPhone static library causes NSInvalidArgumentException

  - by Corey Floyd

  I have created a static library to house some of my code like categories. I have a category for UIViews in "UIView-Extensions.h" named Extensions. In this category I have a method called: - (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration; Calling this method works fine on the simulator on Debug configuration. However, if try to run the app on the device I get a NSInvalidArgumentException: [UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 It seems for some reason UIView-Extensions.h is not being included in the device builds. What I have checked/tried I did try to include another category for NSString, and had the same issue. Other files, like whole classes and functions work fine. It is an issue that only happens with categories. I did a clean all targets, which did not fix the problem. I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups. The static library is included in the main projects "link binary with library" group. Another project I have added the static library to works just fine. I deleted and re-added the static library with no luck -ObjC linker flag is set Any ideas? nm output libFJSCodeDebug.a(UIView-Extensions.o): 000004d4 t -[UIView(Extensions) changeColor:withDelay:duration:] 00000000 t -[UIView(Extensions) fadeInWithDelay:duration:] 000000dc t -[UIView(Extensions) fadeOutWithDelay:duration:] 00000abc t -[UIView(Extensions) firstResponder] 000006b0 t -[UIView(Extensions) hasSubviewOfClass:] 00000870 t -[UIView(Extensions) hasSubviewOfClass:thatContainsPoint:] 000005cc t -[UIView(Extensions) rotate:] 000002d8 t -[UIView(Extensions) shrinkToSize:withDelay:duration:] 000001b8 t -[UIView(Extensions) translateToFrame:delay:duration:] U _CGAffineTransformRotate 000004a8 t _CGPointMake U _CGRectContainsPoint U _NSLog U _OBJC_CLASS_$_UIColor U _OBJC_CLASS_$_UIView U ___CFConstantStringClassReference U ___addsf3vfp U ___divdf3vfp U ___divsf3vfp U ___extendsfdf2vfp U ___muldf3vfp U ___truncdfsf2vfp U _objc_enumerationMutation U _objc_msgSend U _objc_msgSend_stret U dyld_stub_binding_helper

• ScrollView content async downloading problem

  - by Newbee

  Hi! I have UIScrollView with lots of UIImageView inside. In the loadView method I assign some temporary image for each of subview UIImageView images and starts several threads to async download images from internet. Each thread downloads and assign images as follows: NSData *data = [NSData dataWithContentsOfURL:URL]; UIImage *img = [UIImage imageWithData:data]; img_view.image = img; Here is the problem - I expects picture will changed after each image downloaded by I can see only temporary images until all images will downloads. UIScrollView still interact while images downloads - I can scroll temporary images inside it and see scrollers and nothing blocks run loop, but downloaded images doesn't updates.. What I tried to do: Call sleep() in the download thread -- not helps. Call setNeedsDisplay for each ImageView inside ScrollView and for ScrollView -- not helps. What's wrong ? Thanks. Update. I tried some experiments with number of threads and number of images to download. Now I'm sure -- images redraws only when thread finished. For example - if I load 100 images with one thread -- picture updates one time after all images downloads. If I increase number of threads to 10 -- picture updates 10 times -- 10 images appears per update. One more update. I fixed problem by staring new thread from the downloading threads each time one image downloaded and exit current thread (instead of download several images in one thread in the cycle and exit thread only when all downloaded). Obviously it's not a good solution and there must be right approach.
