I am trying to set an attributed string within NSTextView. I want to increase its height based on its content, initially it is set to some default value.
So I tried this method:
I set content in NSTextView. When we set some content in NSTextView its size automatically increases. So I increased height of its super view that is NSScrollView to its height, but NSScrollView is not getting completely resized, it is showing scroller on right.
float xCoordinate = 15.0;
[xContentViewScroller setFrame:NSMakeRect(xCoordinate, 0.0, 560.0, 10.0)];
[[xContentView textStorage] setAttributedString:xContents];
float xContentViewScrollerHeight = [xfContentView frame].size.height + 2;
[xContentViewScroller setFrame:NSMakeRect(xCoordinate, 0.0, 560.0, xContentViewScrollerHeight)];
Can anyone suggest me some way or method to resolve this issue. By doing google search I found that in UITextView there is contentSize method which can get size of its content, I tried to find similar method in NSTextView but could not get any success :(
Based on @Peter Hosey's answer, here is an extension to NSTextView in Swift 4.2:
extension NSTextView {
var contentSize: CGSize {
get {
guard let layoutManager = layoutManager, let textContainer = textContainer else {
print("textView no layoutManager or textContainer")
return .zero
}
layoutManager.ensureLayout(for: textContainer)
return layoutManager.usedRect(for: textContainer).size
}
}
}
