如果不能确定内存释放，最好不要使用uiview动画

建议简单的直线动画使用，cabasicanimation

CABasicAnimation * translation = [CABasicAnimation animationWithKeyPath:@"position"];

        translation.delegate = self;
        ///从屏幕外开始
        translation.fromValue = [NSValue valueWithCGPoint:CGPointMake(kYBScreenWidth + animate_View.frame.size.width/2, animate_View.center.y)];
        translation.toValue = [NSValue valueWithCGPoint:CGPointMake(-animate_View.frame.size.width/2, animate_View.center.y)];
        //         translation.byValue = [NSValue valueWithCGPoint:CGPointMake(announceView.frame.size.width/2, announceView.center.y)];
        translation.removedOnCompletion = NO;
        translation.fillMode = kCAFillModeForwards;
        translation.duration = 5;//动画持续时间跟后面的延迟方法差一秒是驻留时间
        translation.repeatCount = 1;//动画重复次数
        translation.autoreverses = NO;//是否自动重复
        [animate_View.layer addAnimation:translation forKey:@"translation"];
        [self performSelector:@selector(removeAnimate_View) withObject:nil afterDelay:5.1];
