Duplicating Twitterrific Style Alert - iphone

Question

I am trying to replicate the screen in the middle, namely the alert that is displayed to compose a new tweet. I have tried to duplicate it with a custom UIAlertView but that requires a lot of subclassing and what not, then I suspected it might just be a simple UIViewController that is displayed over the main view... professional thoughts from fellow iOS developers is needed.
Thank you.

In iPad:
You can do it with a UIViewController.
You need to design UI according to the above image.
Then you need to set the Modal Presentation Style to UIModalPresentationFormSheet
And present it using - (void)presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))
Like:
UIViewController *viewC = [[UIViewController alloc] init];
viewC.view.frame = //set the frame;
viewC.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:viewC animated:YES completion:nil];
In iPhone:
You can do it with using a UIView.
You can use the following code for doing this:
Declare a property in your interface
#property (nonatomic, strong) UIView *views;
//Add the view
- (void) showView
{
UIToolbar *toolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 35)];
UIBarButtonItem *bar = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(remove)];
toolbar.items = [NSArray arrayWithObject:bar];
_views = [[UIView alloc] initWithFrame:CGRectMake(0, -300, self.view.bounds.size.width, self.view.bounds.size.height/3)];
[_views addSubview:toolbar];
[_views setBackgroundColor:[UIColor grayColor]];
[self.view addSubview:_views];
[UIView animateWithDuration:0.7
delay:0.0
options:UIViewAnimationCurveLinear
animations:^{
_views.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height/3);
}
completion:^(BOOL yes){
NSLog(#"YO");
}];
[UIView commitAnimations];
}
//Remove the view
- (void)remove
{
[UIView animateWithDuration:0.7
delay:0.0
options:UIViewAnimationCurveLinear
animations:^{
_views.frame = CGRectMake(0, -500, self.view.bounds.size.width, self.view.bounds.size.height/3);
}
completion:^(BOOL yes){
NSLog(#"YA");
}];
[UIView commitAnimations];
}
