NSTextField width and autolayout
autolayout, cocoa, nstextfield, nstextview
Solution
Another way to compute the text field optimal width without using `fittingSize` is using the following code (replacing John Sauer's sizeTextFieldWidthToFit method):
- (void) sizeTextFieldWidthToFit {
[textField sizeToFit];
CGFloat newWidth = NSWidth(textField.frame);
textFieldWidthConstraint.constant = newWidth;
}
You can set the priority of textFieldWidthConstraint to be lower than the priority of another inequality constrain the represent your requirement to a minimal size of 25.
Problem
I am trying to create an `NSTextField` programmatically. I want to use this `NSTextField` with auto layout, so its width will be defined automatically to display the entire line (there is only one line of text). The problem is that `textField.intrinsicContentSize` and `textField.fittingSize` are both have -1 and 0 values for the horizontal coordinate, as the output of the code below is: `textField.intrinsicContentSize={-1, 21}` `textField.fittingSize={0, 21}` The code: ``` NSTextField* textField = [[NSTextField alloc] initWithFrame:NSMakeRect(0, 0, 10, 24)]; NSString* str = @"One line of text here."; [textField setStringValue: str]; [textField setTranslatesAutoresizingMaskIntoConstraints:NO]; [textField invalidateIntrinsicContentSize]; NSLog(@"textField.intrinsicContentSize=%@", NSStringFromSize(textField.intrinsicContentSize)); NSLog(@"textField.fittingSize=%@", NSStringFromSize(textField.fittingSize)); ``` This makes the text field to have a zero width assigned by auto layout. What should I do to get meaningful values for the `fittingSize` and `intrinsicContentSize` properties of the text field so they reflect the content of the text field?
