Hi, what approach do you recommend me for downloading a website (one HTML site with all included images) to the iPhone? The question is how to crawl all those tiny bits (Javascripts, images, CSS) and save them locally. It's not about the concrete implementation (I know how to use NSURLRequest and stuff. I'm looking for a crawl/spider ...
I have been wondering how the iPhone determines location based on wifi, because I want to integrate this functionality into a java app of mine. When I run a location check on my ip, it throws me all the way into some other neighborhood... But when I use my iPhone's location feature, it points right too me. (and GPS is turned off) How d...
I have a scroll view embedded into the tableHeaderView of a UITableView. I have a few images that the user can scroll through left/right. Pinch/zoom is not enabled. Initially, I could scroll through the images, but only if I was extremely precise with my horizontal movement. Any deviation would be intercepted by the UITableView as a ver...
I finished building a basic iPhone app and now wants to upgrade the UI. I want to add something very similar to the iphone main screen, the only difference is that I need the UINavigationController to always be visible while I scroll through the views. I tried to play with the PageControl example by apple but couldn't get it working th...
Hi, I'm trying to add a textfield into a navigation bar, but it doesn't show up in the simulator. I do it as follows inside viewdidload: UITextView *textField = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 170, 44)]; self.navigationItem.titleView = textField; Any ideas? Thanks! ...
I want to use the Facebook Graph API in a NATIVE iPhone Application. Has anybody been able to find a way to post images/message on a user's feed? I have tried all possible ways to post a ‘picture’ (not a URL but a UIImage) on the feed and have been working on this for 2 weeks now. If you go to facebook.com you can upload a picture from...
When I try to compress my binary (to upload for app submission), I get a ridiculously small zip file (a 10 meg file turns into 300k). I've done this a dozen times and never had a problem and am uncertain what could be causing this. I tried restarting xcode and doing a clean build. Has anyone seen this happen before? ...
I've run into the issue of using a UIBarButtonItem with a custom color. Everything out on the 'net seems to indicate that the only way around this lack of official API support revolves around the use of images. This is all fine and dandy when developing for pre-iOS 4 devices, except when using the new iPhone 4. Creating an image for i...
I want to have images inside of a UIScrollView (or at least appear to be inside a UIScrollView) that don't change their size when zooming in and out. I do want the images to maintain their positions when zooming or scrolling. The use case is that I have a customized map view with pushpins. I want the pushpins to stay in place when zoo...
I've taken a screenshot of my iPhone app running and I'd like to use that image as a png to be drawn by the app instead of generated graphics. When I take the screenshot, it looks fine. However, when that is saved as a PNG file, added to the Xcode project and then displayed back on the screen of the phone (or simulator) the colours are ...
Hi, please I need some advice about design approaches in iPhone programming. I want to display a table view (with three cells that will never change) and a UIDatePicker. I don't use Interface Builder. I created a UIViewController subclass and tried to put all together in its viewDidLoad method: UITableView *myView = [[UITableView alloc...
Hi, i currently notify users that we have an update to our iphone app using an UIAlertView and when they click ok, i open the phobos.apple.com URL to the app using [[UIApplication sharedApplication] openURL:] That works fine and dandy & brings the user to the app's page in the App Store, but is there a way to just open the App Store a...
I want to use the Facebook Graph API in a NATIVE iPhone Application. I need help to POST images/message on facebook. I know of these two resources on the net but they do not provide any help with posting on the user's feed. http://www.capturetheconversation.com/technology/iphone-facebook-oauth2-graph-api http://blog.corywiles.com/face...
I have a library of 16 short sound clips I need to be able to play in quick succession. I realized that creating and preparing AVAudioPlayer objects in real time was too much to ask of the iPhone. So instead, during my app's initialization, I am pre-creating a series of AVAudioPlayers so that each one is basically pre-loaded with one...
Gentleones, I would like (at another's suggestion) to extend the functionality of a UIImageView or UIImage so that I can display a particular image in a view and ask it about itself. Since it's a graph, I'd like to be able to ask this particular UIImageView what a particular Y value is returned given a particular X value. (Ignore creat...
I am really confused - I am implementing a change to a button in several views and it works in all but 1 of them and I can't figure out what is different. I have it declared in the .h file : UIButton *doSomethingButton; } @property (nonatomic, retain) IBOutlet UIButton *doSomethingButton; But then in the .m file I get the error ...
Hi all, I have an iPhone app that I've developed and I'm ready to submit it to the app store. I've read the iTunes Connect Developer Guide, but there's nowhere that specifies exactly how to go from an app in XCode to a binary uploaded to the app store. Is anyone who has done this able to guide me here? Thanks! Bjorn ...
I have a problem getting the NSUserDefaults to pull out on a tab/nav/tableview controller page, I've put the same code on a loginpage and the app will pull the objects for keys perfectly. I had this working when I had programmatically created the tabs and navs but now it's not working. The loginViewController is not in the tab stack, is ...
