UISearchController使⽤中遇到的各种问题⾸先初始化，这就不细说了，三个代理都写上： _ResultsUpdater = self; _te = self; _te = self;⼀、⾃动弹出键盘以往的写法：- (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; = true;}- (void)didPresentSearchController:(UISearchController *)searchController { [Bar becomeFirstResponder];}实现如上的代码就可以了，但是如果把searchbar写到导航条上，发现这么写完全是没作⽤的。修改：- (void)didPresentSearchController:(UISearchController *)searchController { [UIView animateWithDuration:0.1 animations:^{} completion:^(BOOL finished) { [Bar becomeFirstResponder]; }];}⼆、搜索输⼊时禁⽌searchBar上移隐藏导航条 _avigationBarDuringPresentation = NO;三、修改searchBar取消按钮的颜⾊和⽂字 [[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:[UIColor whiteColor]]; [[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitle:@"取消"];四、显⽰searBar的光标（如果不显⽰可以这么设置） _lor = [UIColor blueberryColor];
