### RAMPaperSwitch classを編集(2020/1/18 05:30追記）
|
|
63
|
+
以下に記載のRAMPaperSwitch class内のUIViewであるが故に、
|
|
64
|
+
今回のcellでは表示できないのではないかと思い、UIView（３箇所）を全てUITableViewCellに変更し
|
|
65
|
+
実行しましたが、switchは表示されませんでした。
|
|
66
|
+
```
|
|
67
|
+
public required init(view: UIView?, color: UIColor?) {
|
|
68
|
+
super.init(frame: CGRect.zero)
|
|
69
|
+
onTintColor = color
|
|
70
|
+
self.commonInit(view)
|
|
71
|
+
}
|
|
72
|
+
```
|
|
73
|
+
その際、ここにエラーが出たのでsuperview as? UITableViewCellとしました
|
|
74
|
+
```
|
|
75
|
+
override open func awakeFromNib() {
|
|
76
|
+
self.commonInit(parentView ?? superview)
|
|
77
|
+
super.awakeFromNib()

###PaperSwitch
|
|
63
81
|
PaperSwitch自体は本来storyboardで配置したswitchのclassをRAMPaperSwitchと
|
|
64
82
|
指定し、onTintColorを指定するだけで利用できると言う優れものです。
