ios - Ios 中 TableView 中的动画

Question

我有一个带有隐藏属性的表格 View 。我想用动画取消隐藏它，以便它可以从下到上滑动？请有任何建议。

-(IBAction) hideTable : (id) sender;
{

if(self.tb.hidden==true)
{
    self.tb.alpha=1;
[self.tb setHidden:NO];
}
else{
[self.tb setHidden:YES];
}
}

-(IBAction) hideTable : (id) sender{

    if (self.sessionView.hidden == YES) {
        // Currently NOT Visible. Show it now

        // First unhide it
        yourTableView.hidden = NO;

        [UIView animateWithDuration:0.5f
                         animations:^{

                             // Get the Existing table View frame
                             CGRect hiddenFrame = yourTableView.frame;

                             // Reset it to 0 or your own value
                             hiddenFrame.origin.y = 0;

                             // Set the new frame
                             yourTableView.frame = hiddenFrame;


                         } completion:^(BOOL finished) {

                             NSLog(@"Shown");
                         }];


    }
    else{
        // Currently Visible. Hide it Now

        [UIView animateWithDuration:0.5f
                         animations:^{

                             // Get the Existing table View frame
                             CGRect hiddenFrame = yourTableView.frame;

                             // Under the superview height
                             hiddenFrame.origin.y = yourTableView.superview.frame.size.height;

                             // Set the new frame
                             yourTableView.frame = hiddenFrame;


                         } completion:^(BOOL finished) {

                             yourTableView.hidden = YES;

                             NSLog(@"Hidden");
                         }];


    }
