Customized photo picker view
提问by Warbean
I want to use photo picker view in customized form, such as showing a rectangle in screen to focus on specified area of the picture. However, UIImagePickerController can only offer a normal photo picker view. Is there any other class I can use to replace UIImagePickerController, or should I create a sub class of UIImagePickerController?
我想以自定义形式使用照片选择器视图，例如在屏幕中显示一个矩形以专注于图片的指定区域。但是， UIImagePickerController 只能提供普通的照片选择器视图。是否有任何其他类可以用来替换 UIImagePickerController，还是应该创建 UIImagePickerController 的子类？
