Sorry Claude31, i'm new to this. Have you 8 components in the pickerView? I understyand No, as you return 1 as number of components. I've deleted some blank lines which make code more difficult to read and added elsewhere to separate different func.

You should also connect its datasource and delegate in IB, by control dragging in Document Outline from the picker up to the viewController and select delegate. Do it again and select datasource. I removed the 2nd object creation for dropDown and now have dropDown. I had previously matched the tag in the IB with the tag in the. I dont understand how to complete your seggestion for line I understand you want to rexecute when edit begins. I typed IBAction in front of func and now have an empty circle beside the line.

I've accomodated for everything by placing a scroll view on the story board and setting the height of the scroll view to Last night I added some switches to the same view also. What statement do i use in case 4, starting at rowto seperate the textfields from eachother when the picker is selected? Or, is there more to do before I do that? What do you mean by : What statement do i use in case 4, starting at rowto seperate the textfields from eachother when the picker is selected?

I am very new to swift and Xcode as youve realised and i'm reading the swift book and other material to try and get my head around it all. Is there a better way to find out what to do or what to use in situations. If that's what the users have asked for, it is good to show first you have the solution. It is a question of logic, looking at the details of what you described :.

That's cleaner. Hope everything is working now and you can deliver to your "customer". Test the app with them and note all their comments, and more important observe how they use, where they have problems understanding how to use, that will give you ideas on how to improve.

Do you want to select items in on pickerView for all 8 fields?Posted on October 21, by Steven Lipton. UIPickerViews are those spinning wheel slot machine type controls. It relies heavily on delegates. I debated just having people go to the UIPickerView lessonand start with that, but decided it would be simpler to start with a single-component picker view instead of the double component in that lesson.

Drag a label and a picker view onto the view controller on the storyboard. Open the Assistant editor, and control-drag from the label to make an outlet named myLabel. Control-drag from the picker view and make an outlet named myPicker.

Close the assistant editor and go to the ViewController. Clean up the code, then add the data for the picker view there so it looks like this:.

UIPickerView needs a delegate and a data source. In the viewDidLoad above we set both the delegate and dataSource to to self so we can add the required methods here. Change the class declaration to this:.

Xcode is whining at you to add some required methods for the protocol. The two methods are in the data source. Add these towards the bottom of your code:. We have only one component for the picker view so we return a literal 1. Add these below the Data Source methods:.

The first method places the data into the picker and the second selects and displays it in the label. You can now build and run and spin the wheel a bit:.

Now that we have set up a picker view, we might want a different font or color. There is a method which uses attributed strings. Add this under the code we already have:. This should change the font to blue 15 point Georgia given the attributed string we have. Build and run. We do get blue, but no font change.ViewController: For this tutorial do all our work in ViewController.

We will add protocols that ViewController implements. Just type them into the class file. Array: The data array has three strings.

iOS UIPickerView

These will be used to populate the UIPickerView. DataSource, delegate: Assign these properties for the "simplePicker" to the "self" class. Both must be assigned.

Funcs: Just paste the funcs into your file at first. These are required to indicate components columns and rows for the Picker View. UIPickerViewDelegate is needed.

Please examine the pickerView funcs above. Set background. Now please set the background of the Picker View to something bright like yellow. It is important to use a bright color for the Picker View to work right. Run simulator. Now click on the right-pointing arrow icon. The iPhone simulator will start and your program may do something useful if you are lucky. We can click on different rows to select them. A list of items appears. One item can be selected.

This is a Picker View. With some custom Swift code we can use it. It will show some cities in California at first.

Once added, please drag the control-drag Picker View to the iPhone screen to add an outlet. Call this outlet "simplePicker.The need to collect data via text input is a common in many applications. Table views provide nice, built-in styles that present a form-like view for collecting data from your users. They also have inherent scrolling capabilities. Finally, there is some handy keyboard handling, such as auto-scrolling to avoid covering up a data entry cell, or hiding the keyboard when the user scrolls the Table View.

Both of those are challenging to get right if you were to do implement a data entry form some other way. For those reasons, I think a table view is a really convenient choice for collecting data from a user. Example Xcode Project. Assuming that you have a View Controller already on the Storyboard design surface, drag a table view onto the Storyboard scene. Use the document outline to set constraints. Configuring constraints on the table view will ensure that it displays properly on all device sizes and orientations.

Now comes the customization of the prototype cell itself. Use the document outline to set constraints for the text field. With the text field selected, and the attributes inspector selected in the utilities pane, set the Border Style property to the style you prefer. Configuring constraints on the text field will ensure that it displays properly on all device sizes and orientations. Add a new.

Swift UIPickerView Example: UIPickerViewDataSource

Use the document outline to select the Table View Cell. With the identity inspector selected in the utilities pane, change the Class property to your TextInputTableViewCell class. Implement the appropriate protocol methods. Lines 9 and 11 are of most importance. Take a look at the example published to GitHub to dive in further and explore the walkthrough in more depth.

Table Views for Data Entry?UIPickerView is a UI element which is used to make a selection from multiple choices displayed in a vertical wheel.

It is quite similar to what a dropdown is in Android or Web UI. A wheel is known as a component in a UIPickerView.

A single UIPickerView can host one or more components. Every component can contain independent data and can be selected and changed. Typically, an array is used to display data in the rows of a UIPickerView component. You must adopt the protocol, UIPickerViewDelegate in order to display the rows and also to allow making user selections. For that, we use the selectedRow inComponent: to get the values from the selected rows of the components.

These are then appended and displayed in a string. Following is the updated code of the ViewController. Hi Anupam, Thanks for such a nice tutorial.

Since this article is not covering size classes and auto-layout, we want to make sure that our UIPickerView is well positioned in the Simulator.

To accomplish this, go to the newly created Main.

From the file navigator on the left, select Main. The list of elements will filter down to the UIPickerView element. Click the Assistant Editor button and make sure that the storyboard is in the left pane and that ViewController. Then hold down control and click the UIPickerView element in the storyboard and drag your mouse over to the right side.

Drop it in between the class ViewController and override func viewDidLoad. Click the GIF to play it.

A small dialog will pop up to ask you for a name for this IBOutlet property. Keep in mind that if you delete this IBOutlet property, you also have to break the connection from the storyboard or else your app will crash. By declaring it here as an instance variable, we can access this variable from any method in this class and the variable will hold its value for the duration of the objects lifetime.

Now that the pickerData was initialized, we will add some data in Line 9, which is part of the viewDidLoad method. Go to ViewController. Line 1 below is what you want to modify.

Also, this code actually sets this ViewController instance as the delegate line 13 and datasource line 13 of the Picker View we added to the storyboard. Add the following methods to your ViewController. For example, if you wanted to do a picker for selecting time, you might have 3 components; one for each of hour, minutes and seconds. The pickerView:titleForRow:forComponent: method asks for the data for a specific row and specific component.

In ViewController. In order to detect what the user has selected with the UIPickerView, we only have to implement one more delegate method:.

However, once you get the hang of using delegates then it makes sense and you can take advantage of other UIElements which leverage delegation too. I am needing to use a picker to select a number from 1 to Can anyone lends a hand on a coding issue I'm having using Xcode 7 - swift.

Any suggestions on how to resolve this issue? I'm extremely new to xcode learning through youtube videos. Do you have any references that could show me how to do this and connect it properly in my code? I just found the tag option in the right view pane when a UIPickerView is selected. Thanks junkpile!

You could just compare the pickerView provided in the method call to the LetterView and NumberView pickerViews that you've defined.

That way, you avoid the potential of not setting the tag in Interface Builder. Control would drop through to the end without returning anything. You could shut the compiler up by adding a "return nil" at the end.

But it would be better to use a switch statement in this case, or better yet, don't use the tag at all It can work in simple cases but here it doesn't help much I think. All those magic numbers 0, 1, etc. What is the array 'd' supposed to contain? If you name things properly and use enums and similar Swift features, it can make the code a lot easier to maintain.
