方法如下:

- (void)showNewStatus:(NSString *)detail
{
    UIButton *btn = [[UIButton alloc] init];
    
    [self.navigationController.view insertSubview:btn belowSubview:self.navigationController.navigationBar];
    
    btn.userInteractionEnabled = NO;
    [btn setBackgroundImage:[UIImage createImageWithColor:[UIColor blueColor]] forState:UIControlStateNormal];
    [btn setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
    btn.titleLabel.font = [UIFont systemFontOfSize:14];
    NSString *title = [NSString stringWithFormat:@"xxxxxx"];
    [btn setTitle:title forState:UIControlStateNormal];
    
    CGFloat btnH = 30;
    CGFloat btnY = 64 - btnH;
    CGFloat btnX = 2;
    CGFloat btnW = self.view.frame.size.width - 2 * btnX;
    btn.frame = CGRectMake(btnX, btnY, btnW, btnH);
    
    [UIView animateWithDuration:0.7 animations:^{
        
        btn.transform = CGAffineTransformMakeTranslation(0, btnH + 2);
        
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:0.7 delay:2.0 options:UIViewAnimationOptionCurveLinear animations:^{
            btn.transform = CGAffineTransformIdentity;
        } completion:^(BOOL finished) {
            [btn removeFromSuperview];
        }];
        
    }];
}
