I'd like to set the image of a UIButton
, but without creating all of the assets at different sizes.
Since it should be just a grey rectangle, with some text on top, I'm trying to do this by creating a CGRect
. The title is displayed as desired, and the button can be clicked for the region described by the CGRect
, but when I run the app, nothing can be seen, except for the title. I tried to fix this by setting the tintColor
, but to no avail.
Here's what I have so far.
@IBOutlet weak var swapButton: UIButton!
In viewDidLoad()
:
var rectangle = CGRectMake(0, 0, view.layer.frame.width, 20)
UIGraphicsBeginImageContext(rectangle.size)
CGContextTranslateCTM(UIGraphicsGetCurrentContext(), rectangle.origin.x, rectangle.origin.y)
var rectangle2 = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
swapButton.setBackgroundImage(rectangle2, forState: .Normal)
swapButton.tintColor = UIColor.blackColor()
Is there any way to accomplish this?
Try this code :
var yourbutton = UIButton(frame:CGRectMake(100, 100, 100, 35))
var rect = CGRectMake(0, 0, 1, 1)
UIGraphicsBeginImageContext(rect.size)
var context : CGContextRef = UIGraphicsGetCurrentContext()
CGContextSetFillColorWithColor(context, UIColor.blackColor().CGColor)
CGContextFillRect(context, rect)
var image : UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
yourbutton.setBackgroundImage(image, forState: UIControlState.Normal)
self.view.addSubview(yourbutton)
