iTunes connect keeps rejecting my binary for an application update and it's driving me mad. Usually I can figure it out but I've tried everything I can think of. Maybe someone can lend a hand :) The error I'm getting is: The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certif...
Hi again everybody. I'm having a problem implementing the TTNavigator + TTWebController to capture links in styled labels and open them in the TTWebController. In my current UIViewController (not a navigation controller), in the viewDidLoad i added (according to TTCatalog sample): TTNavigator* navigator = [TTNavigator navigator]; naviga...
Hello, I'm attempting to test a Store Kit transaction with the iPhone 3.0 SDK. I am basing my code off the sample code in the Store Kit Programming Guide, but I keep getting failed transactions (status: SKPaymentTransactionStateFailed). However, the transaction's error property is nil, so that doesn't shed any light on the situation. ...
I've got an CGFloat but need it as an NSInteger. The float value is like 2.0f, so I don't mind about fractional parts and loosing precision. What's a legal way to convert it into NSInteger without trouble (except the loss of precision, of course)? NSInteger niceInt = niceCGFloat; seems too simple, smells buggy. Maybe you can explain? ...
I have an iphone application which has about 4 tabs. How do I force the program to start on the second tab? Currently I have switched the first and second tab, but the aesthetics are horrid. ...
I've seen some iPhone applications that use a custom image as the background for a grouped UITableView, instead of the standard gray lines. How is this achieved? ...
I have two UILabels. that I want to overlap one atop the other. Call the labels "under" and "over". over: A C E G under: B D F UILabel "over" will have its text drawn in red. "under" will be in blue. The visual effect will be alternating colors between successive letters. What are the controls available to me to exactl...
My son just discovered that he could hit my view's "Done" button, which flips to the previous view, once to start the flip and one or more times as the view is in transition (flipping out). The second and next hits would trigger the same action over again, creating some interesting results, such as ending up with no views visible, but m...
I have two apps, both of which force the user to use the iPhone in landscape mode, in order to have a wider screen, instead of a taller one. One of the things I have found is that my first view will look fine, but all other views come up with their subviews (UIButtons, UIPicker, UIViews) squeezed to one side or clipped (depending on whe...
I have two apps, both of which force the user to use the iPhone in landscape mode, in order to have a wider screen, instead of a taller one. I selected UIInterfaceOrientationLandscapeRight in my plist file as I prefer to hold the iPhone with my right thumb over the iPhone button. Some users would like to have the app start-up in UIInte...
I have a UIWebview that I am loading with custom HTML using loadHtmlString. My HTML has a link that I intercept when tapped so that I can take control and reload the UIWebview with a different HTML string. The code works, but the area where the link text was located is replaced with a gray rectangle that is visible when the new stri...
I would elaborate it as follows : In what order are the different objects and nib files instantiated/initialized ? My understanding is as follows: 1) UIMainApplication function loads the main .nib file specified in info.plist. 2) This .nib file instantiates the Delegate object. 3) When the appDidFinishLoading method runs, it generall...
What image resolution can/should be used as the icon.png file for an iphone app? I know the size is 57 x 57 but what about the resolution? Links to specific documentation relating to iphone app icon design would also be helpful. ...
It's weird that my app does not zoom in when running in the application manager of the iphone like the other apps do. Do you think the problem is related to the simulator? Or have I done something wrong in the settings of the project? ...
Hi, I have a mkannotation located on a mapview which has a mkannotationview as well as a calloutview which when clicked goes to a child uiviewcontroller. I am updating some properties from the callout's uiviewcontroller, but after I'm finished I want to move the annotation's position on the map and change the annotation title and subti...
I have an iphone app using a uitableview where I'd like the "reorder" controls to always be displayed, and have the user swipe to delete rows. The approach I'm currently taking is to put the tableview in edit mode and allow selection in edit mode self.tableView.editing = YES; self.tableView.allowsSelectionDuringEditing = YES; I then ...
I have a tableview with large images that fill the cells and the row heights are set based on the image size. Unfortunately, the table jerks badly when scrolling to the next cell. I've been told that my tableview will scroll more smoothly if I cache the row heights and the images before they are loaded into the table. All my data are st...
I get this cryptic error the first time (and only the first time) my view is loaded due to the following line of code: - (void)viewWillAppear:(BOOL)animated { [textField becomeFirstResponder]; } There is a noticeable (~3 – 4 second, even on the simulator) delay due to this that makes my app feel unresponsive. Does anyone know how ...
It looks like there a few working solutions for using custom true type fonts (ttf) on the iPhone, most notably http://stackoverflow.com/questions/360751/can-i-embed-a-custom-font-in-an-iphone-application/809307#809307 However, this method does not support open type fonts (otf). Has anyone come across a way to make use of otf typefaces?...
I am trying to quickly invert the colors of an existing UIView (turn into a negative, as in a photographic negative). Or to take the colors and turn down the saturation. I think easier than manipulating the bitmap is to take another UIView that is all white(or shades), and to use blendmodes to achieve my goals. I don't see a way to di...
