  • IOS启动页动画(uiview 淡入淡出效果 )2

    Appdelegate里面右个这个函数,只要它没结束,你的等待界面就不会消失。
    以在启动的时候做些动画

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

        

        // Override point for customization after application launch.

        [window addSubview:viewController.view];

        [self.window makeKeyAndVisible];

     

    //装载启动页的视图
        imgview=[[UIImageView alloc]initWithFrame:self.window.frame];
        imgview.image=[UIImage imageNamed:@"Default"];
        imgview.alpha = 0.0;
        [bgView addSubview:imgview];
        
        //动画--淡入
        [UIView beginAnimations:nil context:nil];//标记动画块开始
        [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];//定义动画加速和减速方式
        [UIView setAnimationDuration:0.5];//动画时长
        [UIView setAnimationDelegate:self];
        imgview.alpha = 1.0;
        //动画结束后回调方法
        [UIView setAnimationDidStopSelector:@selector(showArrowDidStop:finished:context:)];
        [UIView commitAnimations];//标志动滑块结束

     

        return YES;

    }

    //动画--淡出
    -(void)hiddenAnimation
    {
        [UIView animateWithDuration:0.5 animations:^{
            imgview.alpha=0.0;
        } completion:^(BOOL finished) {
            [imgview removeFromSuperview];
            [bgView removeFromSuperview];
        }];
    //    [UIView beginAnimations:@"HideArrow" context:nil];
    //    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
    //    [UIView setAnimationDuration:0.5];
    //    [UIView setAnimationDelay:1.0];
    //    imgview.alpha = 0.0;
    //    [UIView commitAnimations];
    }

    - (void)showArrowDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
    {
        [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(hiddenAnimation) userInfo:Nil repeats:NO];
    }
