How to set the zooming effect in all the subviews of UIScrollView

Question

I am going through the sample code ( https://github.com/vfr/Reader ), and tried to add the same zooming effect in all the pages at the same time. for ex: if the user increase the zoom effect in 2nd page it will set the same zoom effect in all the pages. Not getting any idea how to do this...

In Short,how to resize all the subviews of UIScrollView according to the zoomin / zoomout. 总之，如何根据放大/缩小来调整UIScrollView的所有子视图的大小。

Answer 1

The reader you are using provides zoom in and zoom out options by default. If that doesn't work just check if you have allowed multiple touches.
