滑动UIView动画

Question

I have a button and in the button action I want to show my UITableView by sliding from the button and after the cell click it should goest up by sliding effect.I did it by UIViewAnimation by setting the fixed y position and changing the height from 0 to the height

       tableview.hidden=FALSE;
        tableview.frame = CGRectMake(0,myButton.frame.size.height,myButton.frame.size.width, 0);


        [UIView animateWithDuration:AnimationTime animations:^{

              tableview.frame = CGRectMake(tableview.frame.origin.x, tableview.frame.origin.x, tableview.frame.size.width,  200 );


        } completion:^(BOOL finished) {


        }];

But this is not .I wanted a sliding effect.Any help will be appreciable

Answer 1

Use this method for animation. Provide a option for animation style. There a lot of option in objective-c for animation style

[UIView animateWithDuration:15.0f delay:0.0f options:UIViewAnimationOptions animations:^{
        tableview.frame = CGRectMake(tableview.frame.origin.x, tableview.frame.origin.x, tableview.frame.size.width,  200 );
    } completion:^(BOOL finished)
     {

     }];

for your case i thought you should use UIViewAnimationOptionTransitionFlipFromTop as animation options for slide table from top to bottom.By using this your table view get its full height in 15 sec. you can mange that too.

EDIT:

Once you clicked on cell, you want that your tableview goes up with slide effect. Than use

[UIView animateWithDuration:2.0f delay:0.0f options:UIViewAnimationOptionTransitionFlipFromBottom animations:^{
            tableview.frame = CGRectMake(tableview.frame.origin.x, tableview.frame.origin.x, tableview.frame.size.width,  0 );
        } completion:^(BOOL finished)
         {

         }];

for slide up animation.

Problem is not animation, problem is the frame you are defining. Easiest way to do this, is to define open and close frame and use them to animate.. See below..

Define Open and Close frame

-(void)initComponents{
    CGRect rect=tableView.frame;

    rect.origin=myButton.center;

    openFrame=rect;//Assign openFrame before changing the size.

    rect.size=CGSizeZero;
    tableView.frame=rect;

    closeFrame=rect;//Assign closeFrame
}

Call the initComponents function in viewDidLoad to set the initial state of your tableview . Now simply use the functions below on actions where you want to call.

-(void)openMenu{
   [UIView animateWithDuration:.3 animations:^{
        tableView.frame=openFrame;
    }];
}

-(void)closeMenu{
   [UIView animateWithDuration:.3 animations:^{
        tableView.frame=closeFrame;
    }];
}

Thats it. It should work.

Let me know. Cheers.
