跳转控制器时隐藏自定义tabbar

最近因为弄个隐藏自定义的tabbar搞得一时火急火燎. 现在把他记录一下吧, 希望下次可以迅速解决.

1.首先在tabbar控制器中注册通知
@implementation TMTTabBarController

• (void)viewDidLoad {
  [super viewDidLoad];
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(TabBarhidden:) name:@"TabBarhidden" object:nil];
  }

2. 处理通知

pragma mark 通知

• (void)TabBarhidden:(NSNotification *)notification {
  if ([notification.object isEqual:@"hide"]) {
  self.TtabBar.hidden = YES;
  }
  else{
  self.TtabBar.hidden = NO;
  }
  }

3. 在要跳转的控制器中发送通知

//"设置"按钮点击事件

• (void)didClickSettingBtn{

  TMTSettingController *settingVc = [[TMTSettingController alloc] initWithStyle:UITableViewStyleGrouped];
  self.settingVc = settingVc;

  [[NSNotificationCenter defaultCenter] postNotificationName:@"TabBarhidden" object:@"hide"];

  [self.navigationController pushViewController:settingVc animated:YES];
  }
  /**

• 跳转回来时显现tabbar
  */

• (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];
  [[NSNotificationCenter defaultCenter] postNotificationName:@"TabBarhidden" object:@"noHidden"];
  }
