I'm making a project for osx and I need to add multiple NSTextfields to a custom view (NSView) programmatically. I don't know how to achieve this correctly.

This is what I need to do:

enter image description here

I know how to create the NSTextfiedls and how to add them to the NSView, but i dont know how to config them to show like in the image and set them any constraints in code. I'm using autolayout.

You can specify the frames for each Text field. like

NSRect rect = NSMakeRect(xPos,SuperView.frame.size.height - (padding + control_Height),control_Width,control_Height);
`for(int i = 0;i < 3;i++)
{

NSTextField *textField = [[NSTextField alloc] initWithFrame:rect];
[superView addSubView:textField];
[textField release];
rect.origin.y -= (padding + control_Height);

}`

Have a look at using the NSStackView class to hold your text fields. For simple set-ups - like the one in your screenshot - this class does the auto-layout work for you.

To help you get to grips with it, Apple provide a sample demo called InforBarStackView .

The screenshot below is from a program which added a stack view instance to an otherwise empty window in Interface Builder.

enter image description here

The text fields were added with the following code:

// AppDelegate has a stackView outlet
for each in 0...2 {
    var f = NSTextField()
    f.translatesAutoresizingMaskIntoConstraints = false
    stackView.addView(f, inGravity:.Top)
}

  • I dont know how to use stackview. Could you post a more complex example? With stackview can i add multiple items without limit? – user3065901 Feb 05 '15 at 09:54
  • *Could you post a more complex example?* - have updated post to provide a link to an Apple demo showcasing the ``NSStackView``. *Can I add multiple items with limit?* - questions like this are best answered by the documentation for the class. From what I can see the ``NSStackView`` class reference mentions to limit on the subviews it can handle. – Paul Patterson Feb 05 '15 at 12:08
