Swift - 滾動視圖適合整個屏幕？

Question

我的滾動視圖完全不適合屏幕。頂部和左側有一個黑色邊框。它看起來像這樣。

下面是我用它來創建滾動視圖代碼：

imageView = UIImageView(image: UIImage(named: "Map 1.png")) 
scrollView = UIScrollView(frame: view.bounds) 
scrollView.backgroundColor = UIColor.blackColor() 
scrollView.contentSize = imageView.bounds.size 
scrollView.addSubview(imageView) 
view.addSubview(scrollView) 

Answer 1

也許你會刪除 「調整滾動查看插圖」 從UIViewController

Answer 2

imageView = UIImageView(image: UIImage(named: "Map 1.png")) 
imageView.contentMode = .ScaleToFill  
imageView.frame = CGRect(x: 0, y: 0, width: self.scrollView.frame.width , height: self.scrollView.frame.height) 

scrollView.contentSize.width = scrollView.frame.width  
scrollView.addSubview(imageView) 

view.addSubview(scrollView)
