swift - UIImageView with sticker and adding Gesture on Sticker -


i have 1 imageview , sticker on want add gesture on sticker, working ,my sticker going out uiimageview's layer shown in image. want sticker's gesture within imageview's boundaries only.

enter image description here

following code:

func addstickers(image: uiimage) {      gesture = "stickers"      imgsticker  = uiimageview(frame: cgrect.init(x: 0.0, y: 0.0, width: 80, height: 80))     imgsticker.center = view.center     imgsticker.image = image     imgsticker.contentmode = uiviewcontentmode.scaleaspectfill     imgsticker.isuserinteractionenabled = true      self.view.addsubview(imgsticker)     //imgimage.addsubview(imgsticker)      pangesture = uipangesturerecognizer.init(target: self, action: #selector(handlepangesture(_:)))     pangesture.delegate = self      pinchgesture = uipinchgesturerecognizer.init(target: self, action: #selector(handlepinchgesture(_:)))     pinchgesture.delegate = self      rotategesture = uirotationgesturerecognizer.init(target: self, action: #selector(handlerotategesture(_:)))     rotategesture.delegate = self      imgsticker.addgesturerecognizer(pangesture)     imgsticker.addgesturerecognizer(pinchgesture)     imgsticker.addgesturerecognizer(rotategesture) }

i calling function , handle methods below: 

                addstickers(image: #imageliteral(resourcename: "sticker1.png"))

func handlepangesture(_ recognizer: uipangesturerecognizer) {

    if gesture == "stickers" {         let recognizercenter = recognizer.location(in: self .view)         imgsticker.center = recognizercenter      } else {         let recognizercenter = recognizer.location(in: self.view)         txtlabel.center = recognizercenter     }  }  func handlepinchgesture(_ recognizer: uipinchgesturerecognizer) {     if gesture == "stickers" {          imgsticker.transform = imgsticker.transform.scaledby(x: recognizer.scale, y: recognizer.scale)          recognizer.scale = 1.0      } else {         txtlabel.transform = txtlabel.transform.scaledby(x: recognizer.scale, y: recognizer.scale)         recognizer.scale = 1.0     }  }  func handlerotategesture(_ recognizer: uirotationgesturerecognizer) {      if gesture == "stickers" {          imgsticker.transform = imgsticker.transform.rotated(by: recognizer.rotation)          recognizer.rotation = 0.0      } else {         txtlabel.transform = txtlabel.transform.rotated(by: recognizer.rotation)         recognizer.rotation = 0.0     }  }

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
