iOS 渐渐消失的提示框怎么实现

假设需要消失的提示框是view
[UIView animateWithDuration:1.f animations:^{

        view.alpha = 0.f;

    }];
duration参数是时间, 多久消失

-----------------------------------

+(void)showMessage:(NSString *)message

{

    UIWindow * window = [UIApplication sharedApplication].keyWindow;

    UIView *showview =  [[UIView alloc]init];

    showview.backgroundColor = [UIColor blackColor];

    showview.frame = CGRectMake(1, 1, 1, 1);

    showview.alpha = 1.0f;

    showview.layer.cornerRadius = 5.0f;

    showview.layer.masksToBounds = YES;

    [window addSubview:showview];

     

    UILabel *label = [[UILabel alloc]init];

    CGSize LabelSize = [message sizeWithFont:[UIFont systemFontOfSize:17] constrainedToSize:CGSizeMake(290, 9000)];

    label.frame = CGRectMake(10, 5, LabelSize.width, LabelSize.height);

    label.text = message;

    label.textColor = [UIColor whiteColor];

    label.textAlignment = 1;

    label.backgroundColor = [UIColor clearColor];

    label.font = [UIFont boldSystemFontOfSize:15];

    [showview addSubview:label];

    showview.frame = CGRectMake((SCREEN_WIDTH - LabelSize.width - 20)/2, SCREEN_HEIGHT - 100, LabelSize.width+20, LabelSize.height+10);

    [UIView animateWithDuration:1.5 animations:^{

        showview.alpha = 0;

    } completion:^(BOOL finished) {

        [showview removeFromSuperview];

    }];

}
