I have looked everywhere and I could not find a 'good' solution to display a uidatepicker when a tableviewcell is tapped. In the following screenshot, the datepicker slides up from the bottom and the background of the view is dimmed. There are done and cancel buttons on the toolbar within the view that holds the datepicker.
appreciate your help
If you're targeting 3.2 or higher, just assign a view containing the picker and whatever buttons you need as the cell's inputView, override the cell's canBecomeFirstResponder method (if necessary) so it can become the first responder, and call becomeFirstResponder on it when tapped.
If you're still targeting earlier versions, you'll have to add that view with the picker and buttons to the hierarchy, animate the sliding, and so on all manually.

I can't seem to find how I could replace the keyboard when I tap a textfield in the following context:
I have a view controller with a tableview dragged into it with one prototype cell, and in that cell I have 4 textfields. As for my swift files, I have one for the table view (view controller) and one for the cell itself.
I was able to replace the keyboard with a datepicker for one textfield, but do not know how to proceed for a picker view...
Thank you in advance for any help/advice given! Please let me know if you need more detail.
Cheers,

As far as I understand, you are asking to change the input type of the UITextField.
You can make use of inputView property of the UITextField. Set the inputView for the required textField as UIPickerView. It'll automatically change the input type.
One of my view controllers contains a UITableView with custom UITableViewCell's. My custom UITableView cell contains a UIImageView subview that represents a tappable icon. When the user taps anywhere on the custom cell, except the icon subview, I want my didSelectRowAtIndexPath method to be called like normal. But when my icon subview gets tapped, I want a different method to get called, but I can't figure out how to do this. Do I have capture the touch position in the touchesDidBegin method and manually check if the user tapped the icon? That just feels so hacky. Other, cleaner ideas?
Thanks so much for your wisdom!
Simply add a tapGestureRecognizer to the UIImageView in your cell
I'm just looking for advice with this as I have no idea where to start but I think a UIActionSheet is probably best.
What I'd like to have is a pop up window (in my head I picture it as being translucent and dark gray). It will not take up the whole screen and the view underneath will still be visible.
In the pop up section there will be a textfield (with several lines) and underneath this there will be a number of UISwitches.
The pop up will be scrollable and will end with OK/Cancel buttons at the bottom.
Like I said, I really have no idea where to start with this but any advice is more than welcome!
A UIActionSheet is probably not what you are after in this case (although you may want a similar look and feel). Think of an action sheet as a traditional modal OK/cancel/Yes/No type dialog box:
Use the UIActionSheet class to present the user with a set of alternatives for how to proceed with a given task.
From the sound it of it, you need to create a UIView in InterfaceBuilder with a semi-transparent background and various child controls (UISwitches and UITextFields). You create your view using the XIB you have configured and add it as a subview of your UIViewController's view. If you want to mimic the animation you get from an action sheet, you can do that with an AnimationBlock.
I have a UITableView where a cell needs to be filled in with a date by selecting it through a pickerview. Instead of pushing the pickerview onto the navigationController I would want to let it slide up halfway into the screen with the tableview still visible in the upper half of the screen. I've seen some apps doing this neat effect before but I don't see on how to accomplish this.
Anyone some helpful hints on this ?
I did this a little while back and asked about it.
I ended up doing exactly what the highest voted answer says: Put the UIPickerView in the same View as your other items and animate the sliding motion using UIView's beginanimation method.
Add a done button in your tool bar. Add a new target/action to the button to call a method on the UIViewController that has your table view and picker controller. Then have it animate the view back off the screen using a UIView animation block.
I have a nice clean UI within a table view which has a few text fields for the user to fill out. One of the fields is for the user's birthday.
I'd like to have it so that when the user selects the birthday field, a view containing a UIDatePicker would come up as, just like the different keyboards do when selecting a text field.
Can this be done? I would have to prevent the text field from being the first responder (to avoid having the keyboard come up) and I would have to animate the view sliding up if no keyboard was showing before.
Would presenting the view modally be an option? If so how would I go about doing it? From the documentation it seems that modal views still take up the whole screen, I just want to use the lower 216 pixels (height of the keyboard and UIDatePicker).
Any one have any tips on how to go about doing this?
Old question but the correct way to do this these days would be to set the UITextField's inputView to a picker you created somewhere. Something like this:
UIPickerView *myPicker = [[UIPickerView alloc] init];
// set picker frame, options, etc...
// N.B. origin for the picker's frame should be 0,0
[myTextField setInputView:myPicker];
When you go to edit a UITextField, iOS really just displays whatever view is at textField.inputView which by default is the keyboard, you can make it anything you want as long as it's a subclass of UIView.
Regarding animation, take a look at DateCell sample application -
http://developer.apple.com/library/ios/#samplecode/DateCell/Introduction/Intro.html
And in any case, the proper way to do this is set UITextField's inputView to show the picker instead of the keyboard. That's what it's meant to do. More on that here:
How can I present a picker view just like the keyboard does?

I would implement this by just animating a view containing the UIDatePicker, a Done, and Cancel button) up from the bottom of the screen. Using CoreAnimation, this should be pretty easy.
Why are you using a text field if you don't want to accept user input from a keyboard? Instead use a UILabel subclass (where you override the touchesBegan/Ended:withEvent: set of methods to show the UIDatePicker) or a UIButton (where your action is a method which slides up the UIDatePicker).
