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];

     }];

}
