iOS中的UISegmentedControl
我使用的是iOS中的UISegmentedControl,ios,objective-c,uitableview,Ios,Objective C,Uitableview,我使用的是UISegmentedControl和UITableView，但我的查询是段按钮1单击并显示“是”的数据，2按钮单击并显示“否”中的数据，并将A添加到Z部分UITableView第一个按钮单击正确的数据显示并正确地显示“表视图”部分atoz显示，但第二个按钮单击并显示应用程序崩溃` #import "ZnameViewController.h" #import "ZpaleoViewController.h" #import "SWRevealViewController.h"
