Case: (Hold down the option key in the simulator and the zoom gesture will appear when you click the mouse)(1) in VIEWCONTROLLER.M:--scaling things is a uiscrollview other than scrolling, so things that need to be scaled should be placed first in Uiscrollview, such as the imageview here;-While we are zooming, scrollview ourselves do not know which control we want to scale, so scrollview need a proxy to tell it, this agent is generally our controller;-

Last two times, the use of ScrollView is the most common in album use. This is true for every camera picture. The next step is to put the code on the line and readers can figure it out for themselves.First create a Photoscrollview class, inherit from Uiscrollview, can not always write in Viewcontroller. Since it is a photo album, the pit capital is a picture and so on (except video), need is a global imageview to display pictures.// Show Picture @property (nonatomic,strong) Uiimageview *imagevie

This article uses two methods to implement the zoom-in and zoom-out function in OpenGL: Method 1. Change the distance between the "Viewpoint" and the model [change the model viewpoint transformation matrix] There are three problems to solve in this method: ① Smooth transition during Scaling ② When a model is scaled up or down to a certain extent, the scaling speed is slowed down to prevent the viewpoint fr
