iOS 如何设置 UITabBarController 的第n个item为第一响应者

ios 怎么设置 uitabbarcontroller 的第n个item为第一响应者?

uitabbarcontroller 里面有个属性：selectedindex

@property(nonatomic) nsuinteger selectedindex;

uitabbarcontroller *vc = [[uitabbarcontroller alloc]init];

vc.selectedindex = n-1;

[self.navigationcontroller pushviewcontroller:vc animated:yes];
