问题 Hi I'm trying to use gesture recognizer with my sprite kit game , i wrote this code @interface GameScene() <UIGestureRecognizerDelegate>{ UISwipeGestureRecognizer *swipeGestureLeft; ISwipeGestureRecognizer *swipeGestureRight; } @end @implementation GameScene -(id)initWithSize:(CGSize)size{ if(self = [ super initWithSize:size]){ } return self; } -(void)didMoveToView:(SKView *)view{ swipeGestureLeft = [[UIGestureRecognizer alloc]initWithTarget:self action:@selector(swipeLeft)];

问题 I'm new to programming and Spritekit in general, and am interested in exploring the relationship between milliseconds & framerate, and how the update function is used as an intermediary between both. Framerate vs. milliseconds Essentially, the main difference between framerate and time is that time is always consistant, while framerate is not (it could dip due to intensive graphics procedures). However, time is usually checked and set during SKScene's update event (which is called every frame

问题 How can I add some environment variables through a schema and then retrieve those variables using code? For example I want to add an environment variable to describe the "exec_mode" like "development" or "production"... and I though to add this variable directly into the schema "environment variables". Now how can I get this variable back into my code in Swift? 回答1: You can get the environment variables with NSProcessInfo : let env = NSProcessInfo.processInfo().environment if let mode = env[

问题 I'm focusing on the new Test Flight procedure. I developed an application (that I submitted through Xcode to the iTunes Connect portal) that crashes if a UIButton is tapped. Since, the application is available for Beta Testing to Internal Testers, I would expect to see a crash log within the new Crashes section of Xcode 6.3 Beta 4 (see Crashes Organizer Help). But nothing. No crashes available. Is there any particular reason for that? Is this related to the type of testers I'm using? I'm

问题 It has been a while since I have used XCode, but since Apple revieled XCode 6 and the new Metal API I had to check it out. They have released examples, e.g. a converted version of their Basic3D example. I am having problems making them compile and run, though. I had to add paths the Quatz and Metal frameworks for compilation and linking to work - thought that should have worked out of the box with build-in libraries? Also the metal shader compilation step fails, it can not find the metal

问题 I am using custom cocoa class extends from TableViewCell and it doesn't give any error message but the cells do not appear in the tableview. The scroll gets longer but the table cells are not viewable. I typed this in my ViewController : tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "Cell") func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)->UITableViewCell { var cell:CustomTableViewCell? = tableView
