For adjusting the text field to string size you have to calculate the text size with <code>NSString</code>'s <code>sizeWithFont: constrainedToSize: lineBreakMode:</code> before and than adjust the text field's size with setting the frame. 

For vertical alignment look at this <a href="https://stackoverflow.com/questions/1235219/is-there-a-right-way-to-have-nstextfieldcell-draw-vertically-centered-text">question</a> (and the answers).

blocks|key|231092|text|您想要的是可能的，但是您必须创建NSTextFieldCell的一个子类，然后在NSTextField中使用这个子类。要覆盖的关键方法是drawingRectForBounds:、selectWithFrame:和editWithFrame:|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|231093|关于这一点，他甚至提供了一个可下载的版本Here+is+a+blog+post+from+the+fantastic+Daniel+Jalkut。这个帖子已经相当老了，但它应该仍然可以正常工作。|231094|entityMap|0|LINK|mutability|MUTABLE|url|http://www.red-sweater.com/blog/148/what-a-difference-a-cell-makes^0|1W|L|2I|G|2Z|E|0|K|1G|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@]|D|@$9|X|A|Y|1|Z]]|E|$]]|$1|H|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

What you want is possible, but you'll have to make a subclass of NSTextFieldCell, and then use that subclass in your NSTextField. The key methods you want override are <code>drawingRectForBounds:</code>, <code>selectWithFrame:</code>, and <code>editWithFrame:</code>

<a href="http://www.red-sweater.com/blog/148/what-a-difference-a-cell-makes" rel="noreferrer">Here is a blog post from the fantastic Daniel Jalkut</a> about this, he even includes a downloadable version ready to go. The post is fairly old but it should still work fine.

blocks|key|2890453|text|此时，覆盖ViewWillDraw并将您的NSTextField放在其父视图的中心。这也适用于实时调整大小。您还可以在此时调整字体大小，以找到适合新大小的字体。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2890454|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

override ViewWillDraw and position your NSTextField in the center of its parent view at this point. This works with live resizing as well. You can also adjust font size at this point to find a font which fits the new size.

Here is a Swift version of the solution linked to by <a href="https://stackoverflow.com/users/79267/sosborn">sosborn</a> above:
<pre><code>open class VerticallyCenteredTextFieldCell: NSTextFieldCell {
 
 fileprivate var isEditingOrSelecting : Bool = false
 
 open override func drawingRect(forBounds rect: NSRect) -&gt; NSRect {
 let rect = super.drawingRect(forBounds: rect)
 
 if !isEditingOrSelecting {
 let size = cellSize(forBounds: rect)
 return NSRect(x: rect.minX, y: rect.minY + (rect.height - size.height) / 2, width: rect.width, height: size.height)
 }
 
 return rect
 }
 
 open override func select(withFrame rect: NSRect, in controlView: NSView, editor textObj: NSText, delegate: Any?, start selStart: Int, length selLength: Int) {
 let aRect = self.drawingRect(forBounds: rect)
 isEditingOrSelecting = true
 super.select(withFrame: aRect, in: controlView, editor: textObj, delegate: delegate, start: selStart, length: selLength)
 isEditingOrSelecting = false
 }
 
 open override func edit(withFrame rect: NSRect, in controlView: NSView, editor textObj: NSText, delegate: Any?, event: NSEvent?) {
 let aRect = self.drawingRect(forBounds: rect)
 isEditingOrSelecting = true
 super.edit(withFrame: aRect, in: controlView, editor: textObj, delegate: delegate, event: event)
 isEditingOrSelecting = false
 }
 
}
</code></pre>

I am creating cocoa app in which i created <code>NSTextField</code> programmatically like this, 

<pre><code>NSView *superView = [[NSView alloc] initWithFrame:NSMakeRect(0, 300, 1400, 500)];
NSTextField *myTextField = [[NSTextField alloc] initWithFrame:NSMakeRect(180, 100, 1000, 300)];
[myTextField setStringValue:myText];
[myTextField setEditable:NO];
[myTextField setBezeled:NO];
[myTextField setDrawsBackground:NO];
[myTextField setSelectable:NO];
[myTextField setFont:[NSFont fontWithName:@"Futura" size:22]];
[superView addSubview:myTextField];
[superView setAutoresizesSubviews:YES];
[myTextField setAutoresizingMask:NSViewWidthSizable | NSViewHeightSizable];
[self.window.contentView addSubview:superView]; 
</code></pre>

Now i want vertical alignment of my text and it should be adjustable according to text length. 
Anyone have any suggestions? Please share your suggestion :) 

Many Thanks..!!
