Swift-click the arrow to rotate

Let arrowimage = Uiimageview(Image: UIImage(named: "Machine_arrow")!. Imagewithrenderingmode(. Alwaystemplate))

let Arrowbutton = UIButton(frame: cgrectmake, arrowimage. Bounds. Width, arrowimage. Bounds. Height))

Arrowbutton. addsubview(arrowimage)

Arrowbutton. addTarget(self, action: #selector(btnclicked(_: Event:)), forControlEvents:. touchupinside)

Check the position of the user when the button is clicked and forward the event to the corresponding accessorytapped event

func btnclicked (sender: UIButton, event: anyobject) {

let touches = Event.alltouches ()! As nsset

let touch = touches. Anyobject() as! uitouch

let currenttouchposition = touch. Locationinview(selecttable)

let indexpath: nsindexpath = selecttable. Indexpathforrowatpoint(currenttouchposition)!

TableView(selecttable, Accessorybuttontappedforrowwithindexpath:indexpath)

}

// This way, the Accessorybuttontappedforrowwithindexpath method of UITableView is triggered and a indexpath is obtained parameters. With this indexpath parameter, we can distinguish between which of the many buttons the attachment button has a touch event:

func TableView (tableView: uitableview, Accessorybuttontappedforrowwithindexpath Indexpath: Nsindexpath) {

let idx = Indexpath. Row

// Add your own logic here

print(idx)

// Click the arrow to rotate

rotat()

        //  rotatearrow()

}

// rotate animation one

func Rotat () {

// Create a rotation animation

let anim = cabasicanimation(keypath: "transform.rotation")

// rotation angle

Anim.tovalue = 1 * m_pi

// rotate the time required to specify the angle

Anim.Duration = 1

// rotation Repeat Count

Anim.repeatcount = maxfloat

// animation does not remove after execution

Anim.removedoncompletion = true

// add animations to the Laye of the view

arrowimage. Layer. Addanimation(Anim, Forkey: nil)

// Cancel animation

arrowimage. Layer. Removeallanimations()

// This is an animation of the direction of rotation

UIView. Animatewithduration(0.2) {(), Void in

// Specify a rotation angle of 180°

self. Arrowimage. Transform = cgaffinetransformrotate(self. Arrowimage. Transform, cgfloat(m_pi))

}

}

rotate an animation two

func Rotatearrow () {

UIView. Animatewithduration(0.3, animations: {[weak self] ()--( ) in

if let selfie = self {

Selfie. arrowimage. Transform = cgaffinetransformrotate(selfie. Arrowimage. Transform, cgfloat(m_pi/ +))

}

})

}
