copied!<p>So i created a UIViewCOntroller subclass to manage this.</p> <p>on that i wrote this function to add.</p> <pre><code>-(void) addToViewWithAnimation:(UIView *) theView { UIView* myview = self.view; CGRect frame = myview.frame; frame.origin.y = 420; myview.frame = frame; UIView* bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; bgView.backgroundColor = [UIColor blackColor]; bgView.alpha = 0.6; backgroundView = bgView; [theView addSubview: bgView]; // this adds in the dark background [theView addSubview:self.view]; // this adds in the pickerView with toolbar. [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5]; frame = myview.frame; frame.origin.y = 420 - frame.size.height; myview.frame = frame; [UIView commitAnimations]; } </code></pre> <p>I then created the view in IB, here is what my class Header looked like at the end of that. (there is also a UItoolbar on the view i just do not have a reference to it in my Controller)</p> <pre><code>@interface PropertyPickerController : UIViewController { IBOutlet UIPickerView* Picker; IBOutlet UIButton* DoneButton; IBOutlet UIButton* CancelButton; UIView* backgroundView; NSArray* SimpleObjects; id PickerObjectDelegate; SEL PickerObjectSelector; } </code></pre> <p>To then hide the view i use.</p> <pre><code>-(void) removeFromSuperviewWithAnimation { UIView* myview = self.view; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(AnimationDidStop:)]; [UIView setAnimationDuration:0.5]; // set fram below window. CGRect frame = myview.frame; frame.origin.y = 420; myview.frame = frame; backgroundView.alpha = 0; //fades shade to nothing [UIView commitAnimations]; } -(void) AnimationDidStop:(id) object { [self.view removeFromSuperview]; //removes view after animations. [backgroundView removeFromSuperview]; } </code></pre> <p>And last but not least all the delegate functions for the picker.</p> <pre><code> - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { FBSimpleObject* object = (FBSimpleObject*)[SimpleObjects objectAtIndex:row]; return object.Name; } - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1;} - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [SimpleObjects count]; } - (IBAction)CancelButtonClick { [self removeFromSuperviewWithAnimation]; } - (IBAction)DoneButtonClick { //This performs a selector when the done button is clicked, makes the controller more versatile. if(PickerObjectDelegate && PickerObjectSelector) { NSMethodSignature* signature = [PickerObjectDelegate methodSignatureForSelector:PickerObjectSelector]; NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature]; [invocation setTarget:PickerObjectDelegate]; [invocation setSelector:PickerObjectSelector]; [invocation setArgument:&object atIndex:2]; [invocation retainArguments]; [invocation invoke]; } } </code></pre> <p>This is how you do the ToolBar. Basically i use the same concept with a ViewController subclass, and i dont use the standard push view or modal display options. (the example here actually places a Textbox and a toolbar on top of the keyboard.</p> <p>@interface BugEditCommentController : UIViewController { UITextView* Comment; UIToolbar* Toolbar; } -(void) addToViewWithAnimation:(UIView*) theView;</p> <p>To activate this view usually you would call [object becomeFirstResponder]; so if you add this to your view Controller constructor, all you need to do is call [object becomeFirstResponder];</p> <pre><code> NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc addObserver:self selector:@selector(keyboardWillShow:) name: UIKeyboardWillShowNotification object:nil]; [nc addObserver:self selector:@selector(keyboardWillHide:) name: UIKeyboardWillHideNotification object:nil]; </code></pre> <p>abd if you implement this method on your controller (defined in the above code)</p> <pre><code>-(void) keyboardWillShow:(NSNotification *) note { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; CGRect toolbarFrame = Toolbar.frame; CGRect keyboardFrame; CGPoint keyboardCenter; [[note.userInfo valueForKey:UIKeyboardCenterEndUserInfoKey] getValue:&keyboardCenter]; [[note.userInfo valueForKey:UIKeyboardBoundsUserInfoKey] getValue: &keyboardFrame]; //CGRect toolbarRect = Toolbar.center; toolbarFrame.origin.y= keyboardCenter.y - ((keyboardFrame.size.height/2) + (toolbarFrame.size.height)); Toolbar.frame = toolbarFrame; [UIView commitAnimations]; } -(void) keyboardWillHide:(id) object { //you could call [self removeFromSuperviewHere]; } -(void) removeFromsuperViewWithAnimation { [Comment resignFirstResponder]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(AnimationDidStop:)]; CGRect frame = Toolbar.frame; frame.origin.y = 480; Toolbar.frame = frame; [self.view viewWithTag:1].alpha = 0; //fade transparent black background to clear. [UIView commitAnimations]; } -(void)AnimationDidStop:(id) object { [self.view removeFromSuperview]; } </code></pre> <p>hope the additional info helps.</p>
