我有一个imageview和贴纸,现在我想在贴纸上添加手势,一切正常,但,我的贴纸是从uiimageview的图层出来,如图所示。我只想在ImageView的范围内显示标签的姿态。
以下是我的代码:
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)
}
我调用此函数和句柄方法如下:
addStickers(image: #imageLiteral(resourceName: "Sticker1.png"))
func handlepangesture(识别器:uipangesturecognizer){
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
}
}
最佳答案
尝试将self.view.addSubview(imgSticker)
中的self.view替换为正在编辑的图像的imageview,即在其上粘贴标签的图像视图。希望有帮助。
所以,应该是这样-imageView.addSubview(stickerOnImg)
。我以前也遇到过同样的问题,这对我很有效。
