私はipadアプリケーションのためにspliviewcontrollerを使用しています。また、spliviewの左側にあるuitableviewの並べ替えを実装しました。私が達成したいのは、ユーザーがtableCellを並べ替えることができますが、3つの白い棒に触れる必要はありません。ユーザーはセルのどこに触れてもそれを並べ替えることができるはずです。出来ますか？並べ替えコントロールを表示せずにuitableviewcellを並べ替えるにはどうすればいいですか？
私はそれが古い質問だと知っていますが、スウィフト助手が将来の冒険を求めるのに役立つはずです。

THIS IS A HACK!
It uses undocumented controls and class names, and will need to be revised with every iOS release.
Usage:
Call the 'transform' method after the cell is displayed - i.e. tableView(tableView: UITableView!, willDisplayCell cell: UITableViewCell! ...
Adopted from:
http://b2cloud.com.au/how-to-guides/reordering-a-uitableviewcell-from-any-touch-point
In case of failure:
- print names of all subviews
- find the new 'UITableViewCellReorderControl' and reflect changes to the code below

以下のクラスは、リオーダコントロールを非表示にして並べ替えのための全体のUITableViewCellが触れるようになります。さらに、コンテンツビューを元のサイズにリサイズすることは自動レイアウトには重要です。ここで

}
@implementation UITableViewCellReorder
#define REORDER_CONTROL_CLASSNAME @"UITableViewCellReorderControl"
/*

of the cell. This is important for autolayout!
Do not call this method on super, as we don't need any further layouting wihtin the cell itself.

は、私はそれはあなたがセルの任意の部分に触れるユーザーに基づいてセルを並べ替えるようになる書いたいくつかのコードです。私はUITableViewをサブクラス化し、どのセルがタップされたかを把握し、前後に移動させるためにtouchesBeganとのメソッドを使用しました。その基本的なコードは、ご質問がある場合はお知らせください。
class ReorderTableView: UITableView {
var customView:UIImageView?
var oldIndexPath:NSIndexPath?
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
guard let touch1 = touches.first else{
return
}
oldIndexPath = self.indexPathForRowAtPoint(touch1.locationInView(self))
guard (oldIndexPath != nil) else{
return
}
let oldCell = self.cellForRowAtIndexPath(self.oldIndexPath!)
customView = UIImageView(frame: CGRectMake(0, touch1.locationInView(self).y - 20, self.frame.width, 40))
customView?.image = screenShotView(oldCell!)
customView?.layer.shadowColor = UIColor.blackColor().CGColor
customView?.layer.shadowOpacity = 0.5
customView?.layer.shadowOffset = CGSizeMake(1, 1)
self.addSubview(customView!)
oldCell?.alpha = 0
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
guard let touch1 = touches.first else{
return
}
let newIndexPath = self.indexPathForRowAtPoint(touch1.locationInView(self))
guard newIndexPath != nil else{
return
}
guard oldIndexPath != nil else{
return
}
if newIndexPath != oldIndexPath{
self.moveRowAtIndexPath(oldIndexPath!, toIndexPath: newIndexPath!)
oldIndexPath = newIndexPath
self.cellForRowAtIndexPath(self.oldIndexPath!)!.alpha = 0
}
self.customView!.frame.origin = CGPointMake(0, touch1.locationInView(self).y - 20)
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.customView?.removeFromSuperview()
self.customView = nil
guard (oldIndexPath != nil) else{
return
}
self.cellForRowAtIndexPath(self.oldIndexPath!)!.alpha = 1
}
func screenShotView(view: UIView) -> UIImage? {
let rect = view.bounds
UIGraphicsBeginImageContextWithOptions(rect.size,true,0.0)
let context = UIGraphicsGetCurrentContext()
CGContextTranslateCTM(context, 0, -view.frame.origin.y);
self.layer.renderInContext(context!)
let capturedImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return capturedImage
}
}
