1. python driver.hide_keyboard() 运行于模拟器上，该方法不起作用，大家有用过么？

2.

sleep(5) 
origin_el = self.driver.find_element_by_name('Buttons, Various uses of UIButton')
destination_el = self.driver.find_element_by_name('Transitions, Shows UIViewAnimationTransitions')
self.driver.scroll(origin_el, destination_el) 

使用时会报错，如下：
