I can't get a border onto my buttons in Xcode 5 without setting them directly in the code. Is it possible that there's no way to do this on the storyboard without making a custom background image?
You can use key path.
For example the corner radius (layer.cornerRadius
) as describe on the image.
You will not be able to see the effects on storyboard, cause this parameters are evaluated at runtime. Now you can use a swift category in UIView (code bellow the picture) in with @IBInspectable
to show the result at the storyboard (If you are using the category, use only cornerRadius
and not layer.cornerRadius
as a key path.
extension UIView {
@IBInspectable var cornerRadius: CGFloat {
get {
return layer.cornerRadius
}
set {
layer.cornerRadius = newValue
layer.masksToBounds = newValue > 0
}
}
}
Here is category from Peter DeWeese answer that allow use keypath layer.borderUIColor
to set the border color.
CALayer+XibConfiguration.h:
#import <QuartzCore/QuartzCore.h>
#import <UIKit/UIKit.h>
@interface CALayer(XibConfiguration)
// This assigns a CGColor to borderColor.
@property(nonatomic, assign) UIColor* borderUIColor;
@end
CALayer+XibConfiguration.m:
#import "CALayer+XibConfiguration.h"
@implementation CALayer(XibConfiguration)
-(void)setBorderUIColor:(UIColor*)color
{
self.borderColor = color.CGColor;
}
-(UIColor*)borderUIColor
{
return [UIColor colorWithCGColor:self.borderColor];
}
@end
Swift 3 If you want to see the result in IB when you use IBInspectable, you have to extend UIView and add the properties to that class, i.e.
@IBDesignable class MyView: UIView {}
extension MyView {
@IBInspectable var cornerRadius: CGFloat {
get {
return layer.cornerRadius
}
set {
layer.cornerRadius = newValue
layer.masksToBounds = newValue > 0
}
}
@IBInspectable var borderWidth: CGFloat {
get {
return layer.borderWidth
}
set {
layer.borderWidth = newValue
layer.masksToBounds = newValue > 0
}
}
@IBInspectable var borderColor: UIColor {
get {
return UIColor.init(cgColor: layer.borderColor!)
}
set {
layer.borderColor = newValue.cgColor
}
}
}
