NSTextField with rounded corners? - objective-c

Question

I'm trying to draw rounded corners around an NSTextField.
I've subclassed NSTextField, tried the code below, but without any result...
Any ideas?
- (void)drawRect:(NSRect)dirtyRect
{
// black outline
NSRect blackOutlineFrame = NSMakeRect(0.0, 0.0, [self bounds].size.width, [self bounds].size.height-1.0);
NSGradient *gradient = nil;
if ([NSApp isActive]) {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.24 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.374 alpha:1.0]];
}
else {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.55 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.558 alpha:1.0]];
}
[gradient drawInBezierPath:[NSBezierPath bezierPathWithRoundedRect:blackOutlineFrame xRadius:5 yRadius:5] angle:90];
}

Answer 1

It is better to subclass NSTextFieldCell to draw rounded corners to preserve NSTextField functionality, e.g:
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
NSBezierPath *betterBounds = [NSBezierPath bezierPathWithRoundedRect:cellFrame xRadius:CORNER_RADIUS yRadius:CORNER_RADIUS];
[betterBounds addClip];
[super drawWithFrame:cellFrame inView:controlView];
if (self.isBezeled) {
[betterBounds setLineWidth:2];
[[NSColor colorWithCalibratedRed:0.510 green:0.643 blue:0.804 alpha:1] setStroke];
[betterBounds stroke];
}
}
Yields a nice rounded text field that works perfectly (if you had set it to draw a rectangle bezel in the first place, at least):

You are doing almost everything correct. You just need to change the textField's cell and radius which match. Take a look at this:
-(void)awakeFromNib {
[[self cell] setBezelStyle: NSTextFieldRoundedBezel];
}
- (void)drawRect:(NSRect)dirtyRect
{
NSRect blackOutlineFrame = NSMakeRect(0.0, 0.0, [self bounds].size.width, [self bounds].size.height-1.0);
NSGradient *gradient = nil;
if ([NSApp isActive]) {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.24 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.374 alpha:1.0]];
}
else {
gradient = [[NSGradient alloc] initWithStartingColor:[NSColor colorWithCalibratedWhite:0.55 alpha:1.0] endingColor:[NSColor colorWithCalibratedWhite:0.558 alpha:1.0]];
}
[gradient drawInBezierPath:[NSBezierPath bezierPathWithRoundedRect:blackOutlineFrame xRadius:10 yRadius:10] angle:90];
}
This is working for me nicely.

Swift 3 version of #Verious codes, with properties editable in Interface Builder:
class RoundedTextFieldCell: NSTextFieldCell {
#IBInspectable var borderColor: NSColor = .clear
#IBInspectable var cornerRadius: CGFloat = 3
override func draw(withFrame cellFrame: NSRect, in controlView: NSView) {
let bounds = NSBezierPath(roundedRect: cellFrame, xRadius: cornerRadius, yRadius: cornerRadius)
bounds.addClip()
super.draw(withFrame: cellFrame, in: controlView)
if borderColor != .clear {
bounds.lineWidth = 2
borderColor.setStroke()
bounds.stroke()
}
}
}

I did like this and it is working like charm.
yourLableName.wantsLayer = YES;
yourLableName.layer.cornerRadius = yourLableName.frame.size.width/2;

The easiest one is to do with interface builder, unless you want the corners rounded by some units:
Simply select the border as rounded one :
