IOS疯狂基础之 代码片段

圆形view

//    UIView *backViewSet=[[UIView alloc]initWithFrame:CGRectMake(0,0,80,80)];

//    backViewSet.backgroundColor=[UIColor blackColor];

//    backViewSet.alpha=0.5f;

//    backViewSet.layer.cornerRadius=40.0f;

//    backViewSet.layer.masksToBounds=NO;

隐藏NavBar用的，不写在viewdidload中

- (void)viewWillAppear:(BOOL)animated {

    [self.navigationControllersetNavigationBarHidden:YESanimated:YES];

    [superviewWillAppear:animated];

}

通过nib文件实例化

    AnimationViewController *controller = [[AnimationViewControlleralloc]

                                          initWithNibName:@"AnimationViewController"

                                          bundle:nil];

   self.title =@"首页";

    [self.navigationControllerpushViewController:controlleranimated:YES];

Delegate中的一些

    //self.window.rootViewController = self.LoginView;

     self.navController = [[UINavigationControlleralloc]initWithRootViewController:self.LoginView];

    [self.windowaddSubview:self.navController.view];

    // 导航按钮创建

    UIBarButtonItem *reloadButton = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh

                                                                                 target:self

                                                                                 action:@selector(reload)];

    self.navigationItem.rightBarButtonItem = reloadButton;

    // 返回按钮

    UIBarButtonItem * BackBtn = [[UIBarButtonItemalloc] initWithTitle:@"返回"style:UIBarButtonItemStyleBorderedtarget:selfaction:@selector(GoBack:)];

    self.navigationItem.leftBarButtonItem = BackBtn;
