问题 I am using Multi-peer connectivity framework and have tried Apple example it works fine, but I want to modify it and instead of using inbuilt browser view controller UI i want to do it with my own UI / code , is it possible to discover devices without the inbuilt UI ?

问题 I am laying out a UICollectionViewCell in IB, and one of the UILabels I am adding is not behaving the way I would expect with autolayout. The desired behavior is: the label's width is at most 385px; the label's right edge stays at least 30px away from the edge of it's container; the label takes up as much vertical space as necessary to fit up to three lines of text. I have working constraints set up to handle the width (and padding). The problem is with the calculated frame height of label.

问题 I'm using Brad Larson's GPUImage framework. However when I'm trying to apply kuwahara filter with filter radius 5.0f , I'm getting artifacts on an iPhone 4S. (works fine on higher performance devices) Source image size was 2048x2048px. By reading original developer's comments I understood that there's a kind of watchdog timer which fires when something takes too long to run on the GPU. So my question is , what is the maximum possible resolution for an iPhone 4S I can apply Kuwahara filter

问题 Using UICollectionView and excellent help given on here on StackOverflow, I've been able to build a "Gantt Chart" style control for my iPhone: Cosmetics aside (I'm doing the functional right now, I've got a graphics designer on tap to look at colors and all that). Background aside, the spans were relatively straightforward to do with a custom UICollectionViewLayout subclass. Each span is an item . But I need to add some functionality, and am unsure how to proceed. Where I'm trying to go is

问题 I have this appearance related code that was working fine in iOS 5: -(void)customizeBackButton:(UIBarButtonItem*)backButtonItem {; [backButtonItem setBackgroundImage:[UIImage imageNamed:@"backbuttonitem"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; } This method is called within viewDidLoad in normal UIViewController . Backbutton is a connected IBOutlet of a UIBarButtonItem, placed in a UIToolbar, and I am correctly seeing it when debugging. The point is that I can change

问题 I want to create a leaderboard in Game Center for the best scores submitted today, and I want it reset every day at midnight. It's not hard to just create a "most recent score" leaderboard and keep track of the score for the day in the app and submit it, however my concern is that users who do not launch the app the next day will have an old score which remains in the "best score today" board until they launch it. Is there any way to make scores expire, or only show the current scores for the
