更新到最新的Swift版本問題

Question

我剛更新到最新版本的Swift，並且遇到了斷點錯誤問題。控制檯中沒有錯誤。

backgroundsetting.innerColor = UIColor.rgb(fromHex: 0xB0E7D7) 

backgroundsetting.outterColor = UIColor.rgb(fromHex: 0x005E7D) 

backgroundsetting.frame = (frame: CGRect(x: self.view.frame.size.width * 0, y: self.view.frame.size.height * 0, width:self.view.frame.size.width, height: self.view.frame.size.height)) 
self.view.addSubview(backgroundsetting) 

然後，更新後要我設置backgroundsetting.frame as! CGRect，當我打開應用程序的那部分它崩潰的應用程序。爲什麼會發生？這裏是後代碼：

backgroundsetting.innerColor = UIColor.rgb(fromHex: 0xB0E7D7) 

backgroundsetting.outterColor = UIColor.rgb(fromHex: 0x005E7D) 

backgroundsetting.frame = (frame: CGRect(x: self.view.frame.size.width * 0, y: self.view.frame.size.height * 0, width:self.view.frame.size.width, height: self.view.frame.size.height)) as! CGRect 
self.view.addSubview(backgroundsetting) 

Answer 1

的backgroundsetting.frame屬性是一個類型的CGRect，爲什麼不建立一個CGRect這樣的：

backgroundsetting.frame = CGRect(x: self.view.frame.size.width * 0, y: self.view.frame.size.height * 0, width:self.view.frame.size.width, height: self.view.frame.size.height) 

Answer 2

如果使用約束爲您的視圖，然後使用高度： self.view.frame.size.height和width：self.view.frame.size.width，與iPhone屏幕相比，它不會顯示適當的高度和寬度。

爲了更好地使用UIScreen尺寸，例如UIScreen.main.bounds.height和UIScreen.main.bounds.width，它將始終顯示iPhone的原始寬度和高度。

backgroundsetting.frame = CGRect(x: self.view.frame.size.width * 0, y: self.view.frame.size.height * 0, width:UIScreen.main.bounds.width, height: UIScreen.main.bounds.height) as! CGRect 
    self.view.addSubview(backgroundsetting)
