custom picker view animation like action sheet - iphone

Question

How to animate custom picker view like actionsheet?
UIView *view = [[[UIView alloc]initWithFrame:CGRectMake(0,300,320,300)] autorelease];
view.backgroundColor = [UIColor brownColor];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:[self view] cache:YES];
[view setFrame:CGRectMake(0.0f,300.0f,320.0f,325.0f)];
[UIView commitAnimations];

Answer 1

Just like you did:
UIView *view=[[[UIView alloc]initWithFrame:CGRectMake(0,460,320,300)]autorelease];
view.backgroundColor=[UIColor brownColor];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:[self view] cache:YES];
[view setFrame:CGRectMake(0,0,320,300)];
[UIView commitAnimations];
But have a look at CGRect. Its (x,y,width,height). So you have to use the second parameter (y position) to animate the vertical position of your view.

Correct answer is this for custom picker view but it won't animate like action sheet. But it creates custom picker view.
items =[[NSArray alloc]initWithObjects:#"Hindi",#"English",nil];
pickerView=[[UIPickerView alloc] initWithFrame:CGRectMake(10,250,350,350)];
pickerView.transform = CGAffineTransformMakeScale(0.75f, 0.75f);
pickerView.delegate = self;
pickerView.dataSource = self;
pickerView.showsSelectionIndicator = YES;
pickerView.backgroundColor = [UIColor clearColor];
[pickerView selectRow:1 inComponent:0 animated:YES];
[self.view addSubview:view];
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
return [items count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return[items objectAtIndex:row];
}
