我正在运行Xcode 6.4,在游乐场玩,我写了这个超级基本代码。
我想在模拟器中运行代码,所以我打开了实用工具选项卡(alt-cmd-0) 并选中支票簿“[v]在完全模拟器中运行”
import UIKit
import XCPlayground
let eenView = UIView(frame: CGRectMake(0, 0, 100, 100))
eenView.backgroundColor = UIColor.orangeColor()
XCPShowView("View", eenView)
模拟器正在显示,还有视图,但是......它正在闪烁!!
(我尝试了很多东西,比如重置所有的模拟器,创建新的模拟器,似乎没什么用,我想知道我是否需要在我的代码中添加一些内容)
答案 0 :(得分:3)

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()
这是解决方案,如果有人感兴趣的话......
我修改了ilyapuchka的代码(他意识到非常好的例子):
