iOS模拟器在两次触摸后才显示正确的场景

Question

我正在使用主菜单创建游戏，但是当我在iOS模拟器中运行游戏时，它无法正确显示场景，如下面的屏幕截图所示。

但是，当我移动到选项菜单场景并返回主菜单场景时，它会以正确的方式显示场景。

这是主菜单的代码：

let playButton = SKSpriteNode(imageNamed: "PlayButton")
let optionButton = SKSpriteNode(imageNamed: "Options")
let facebookButton = SKSpriteNode(imageNamed: "Facebook")
let twitterButton = SKSpriteNode(imageNamed: "Twitter")
let gamecenterButton = SKSpriteNode(imageNamed: "Gamecenter")
let nosoundButton = SKSpriteNode(imageNamed: "Nosound")

let runningBar = SKSpriteNode(imageNamed: "Bar")
let character = SKSpriteNode(imageNamed: "Character")
let backgroundImage = SKSpriteNode(imageNamed: "Background")
let mountains = SKSpriteNode(imageNamed: "Mountains")
let water = SKSpriteNode(imageNamed: "Water")
let sand = SKSpriteNode(imageNamed: "Sand")
let sun = SKSpriteNode(imageNamed: "Sun")
let cloud01 = SKSpriteNode(imageNamed: "Cloud01")
let cloud02 = SKSpriteNode(imageNamed: "Cloud02")
let cloud03 = SKSpriteNode(imageNamed: "Cloud03")

Answer 1

尝试将CGRectGetMinX(self.frame)替换为0，将CGRectGetMaxX(self.frame)替换为self.frame.size.width y位置。

Answer 2

解决方案：

我已将scene.size = skView.bounds.size添加到视图中。这解决了这个问题。
