使用cameraOverlayView的takePicture()

Question

我正在使用cameraOverlayView创建一个自定义摄像头。然而，我不确定如何让按钮拍摄照片。苹果公司的文件说，takePicture()是要使用的功能。但是它不能编译：

两种尝试都不起作用：

let shootPicture = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Camera, target: self, action: takePicture())

let shootPicture = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Camera, target: self, { action -> Void in
            takePicture()
        })

更新后的尝试：

let shootPicture = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Camera,  style: UIBarButtonItemStyle.Plain, target: self, action: "takePicture")

// separate function
func takePicture() {
        imagePicker.takePicture()
}

仍收到语法错误：missing argument for parameter 'landscapeImagePhone' in call

但是当我添加调用时，我得到"extra argument 'landscapeImagePhone‘in landscapeImagePhone: UIBarButtonSystemItem.Camera“

Answer 1

对于其他坚持这一点的人：

设置条形项：

let shootPicture = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Camera,  target: self, action: "takePicture")

创建函数

func takePicture() {
    imagePicker.takePicture()
}
