Do you have any evidence that iOS 7 handles PGUP/PGDOWN in this app normally? Does it work with a regular Bluetooth keyboard? These keys are not normally present on iOS...

YES,you're right,the button function (page up/page down)of regular Bluetooth keyboard also can'work, but the wps ppt has function of the laser pen . As shown:the picture of attachment . I prefer to know how to get the function of the button function (page up/page down) in the app wps ppt? or what I should do to make the the button function (page up/page down)work in IOS 7 ?

Perhaps you could ask Kingsoft which scan code they are expecting for this function in the wps ppt app, if I understand what you are trying to achieve? Then just send that from your firmware.
