使用 Playground 在模拟器中闪烁 UIView
Flickering UIView in simulator using Playground
我运行宁Xcode6.4,玩playground,我写的这个超级基础的代码
我想 运行 模拟器中的代码,所以我打开了实用程序选项卡 (alt-cmd-0)
并选择支票簿“ [v] 运行 in Full Simulator”
import UIKit
import XCPlayground
let eenView = UIView(frame: CGRectMake(0, 0, 100, 100))
eenView.backgroundColor = UIColor.orangeColor()
XCPShowView("View", eenView)
正在显示模拟器和视图,但是...闪烁!!
(我已经尝试了很多东西,比如重置所有模拟器,创建新的模拟器,似乎没有任何效果,我想知道我是否需要在我的代码中添加一些东西)
更新
import UIKit
//setup
struct MainScene {
let vc: UIViewController
let nc: UINavigationController
init(vc: UIViewController) {
self.vc = vc
self.nc = UINavigationController(rootViewController: vc)
}
}
extension UIViewController {
class func viewController(color: UIColor) -> UIViewController {
let vc = UIViewController()
vc.view = UIView(frame: UIScreen.mainScreen().bounds)
vc.view.backgroundColor = color
return vc
}
}
let vc = UIViewController.viewController(UIColor.lightGrayColor())
vc.title = "title"
////////Write your prototype code there
////////End of your prototype
let mainScene = MainScene(vc: vc)
//Run playground
let window = UIWindow(frame: UIScreen.mainScreen().bounds)
window.rootViewController = mainScene.nc
window.makeKeyAndVisible()
CFRunLoopRun()
这就是解决方案,如果有人感兴趣...
我修改了ilyapuchka的代码(他实现了很好的例子):
