I have a method for repeating or tiling an image across a view using UIColor patternImage:
view.backgroundColor = UIColor(patternImage: UIImage(named:imageName))
The default behaviour of UIColor patternImage is to start the pattern from the top left, the result shown in Image 1.
Question:
How can I get UIColor patternImage to start always from the very center of a view, patterning outwards to give the result shown in Image 2?
This works. It is a generalised method that applies more broadly, adapting dynamically to both pattern images and views of different heights and widths. It gives the desired result in the question and is tested on different iOS simulators.
view.backgroundColor = UIColor(patternImage: UIImage(named: "imageName")!)
view.bounds.origin.x = (UIImage(named: "imageName")!.size.width/2) - (view.bounds.size.width/2)
view.bounds.origin.y = (UIImage(named: "imageName")!.size.height/2) - (view.bounds.size.height/2)
If your image size is 50*50 then you can do something like this,
myView = UIVIew(frame: CGRect(x: (self.view.frame.size.width/2)-25, y: (self.view.frame.size.height/2)-25, width: 50, height: 50))
So this view(imageview in yourcase may be) will be place at exact middle of view. Like wise you can arrange other view by adding or substracting view's width and height to center view's x and y origin. Hope this will help you. :)
I created reusable class PatternView, reusing idea of #user4806509. It's really drop-in component for showing patterns. Also, patternImage can be set via Interface Builder
class PatternView: UIView {
#IBInspectable var patternImage: UIImage?
override func awakeFromNib() {
super.awakeFromNib()
self.setupBackgroundColor()
}
private func setupBackgroundColor() {
guard let patternImage = self.patternImage else {
return
}
self.backgroundColor = UIColor(patternImage: patternImage)
}
override func layoutSubviews() {
super.layoutSubviews()
self.centerPattern()
}
private func centerPattern() {
guard let patternSize = self.patternImage?.size,
patternSize.width > 0, patternSize.height > 0 else {
return
}
let x = -self.bounds.width.remainder(dividingBy: patternSize.width)/2
let y = -self.bounds.height.remainder(dividingBy: patternSize.height)/2
self.bounds.origin = CGPoint(x: x, y: y)
}}

I have a tab bar. I changed its colour, gave it a corner radius, set its border width and colour, and everything is working good. Until now, everything is done in a storyboard.
Now I want to give it left and right margins, as by default it is sticking to the screen's edges.
This is the tab bar's current look:
The black arrows point to the lines that stick to the screen's edges. I want space between this line and the edges.
You can create this placeholder view inside a custom UITabBar as below,
class CustomTabBar: UITabBar {
let roundedView = UIView(frame: .zero)
override func awakeFromNib() {
super.awakeFromNib()
roundedView.layer.masksToBounds = true
roundedView.layer.cornerRadius = 12.0
roundedView.layer.borderWidth = 2.0
roundedView.isUserInteractionEnabled = false
roundedView.layer.borderColor = UIColor.black.cgColor
self.addSubview(roundedView)
}
override func layoutSubviews() {
super.layoutSubviews()
let margin: CGFloat = 12.0
let position = CGPoint(x: margin, y: 0)
let size = CGSize(width: self.frame.width - margin * 2, height: self.frame.height)
roundedView.frame = CGRect(origin: position, size: size)
}
}
Set this class for TabBar in storyboard/xib. It should give you the following,
So here's one I just can't seem to find a matching case for in searching on here.
I have a small UIView that contains a UITextView, and the UIView needs to auto-size around the TextView for presentation over another view. Basically the TextView needs to fully fill the UIView, and the UIView should only be big enough to contain the TextView.
The TextView just contains a couple sentences that are meant to stay on the screen until an external thing happens, and certain values change.
Everything is great when I used a fixed-size font.
But hey... I'm an old guy, and I have the text size jacked up a bit on my phone. Testing it on my device shows where I must be missing something.
When using the dynamic font style "Title 2" in the textview properties, and turning on "Automatically adjust font" in the TextView properties, and having the text larger than the default, it seems as if I'm not properly capturing the size of the TextView's growth (with the bigger text) when creating the new bounding rect to toss at the frame. It's returning values that look a lot like the smaller, default-size text values rather than the increased text size.
Code is below, the view's class code as well as the calling code (made super explicit for posting here). I figure I'm either missing something silly like capturing the size after something happens to the fonts, but even moving this code to a new function and explicitly calling it after the controls fully draw doesn't seem to do it.
I hope this make sense.
Thanks, all.
Calling code:
let noWView:NoWitnessesYetView = (Bundle.main.loadNibNamed("NoWitnessesYetView", owner: nil, options: nil)!.first as! NoWitnessesYetView)
//if nil != noWView {
let leftGutter:CGFloat = 20.0
let bottomGutter:CGFloat = 24.0
let newWidth = self.view.frame.width - ( leftGutter + leftGutter )
let newTop = (eventMap.frame.minY + eventMap.frame.height) - ( noWView.frame.height + bottomGutter ) // I suspect here is the issue
// I suspect that loading without drawing is maybe not allowing
// the fonts to properly draw and the
// TextView to figure out the size...?
noWView.frame = CGRect(x: 20, y: newTop, width: newWidth, height: noWView.frame.height)
self.view.addSubview(noWView)
//}
Class code:
import UIKit
class NoWitnessesYetView: UIView {
#IBOutlet weak var textView: EyeneedRoundedTextView!
override func draw(_ rect: CGRect) {
let newWidth = self.frame.width
// form up a dummy size just to get the proper height for the popup
let workingSize:CGSize = self.textView.sizeThatFits(CGSize(width: newWidth, height: CGFloat(MAXFLOAT)))
// then build the real newSize value
let newSize = CGSize(width: newWidth, height: workingSize.height)
textView.frame.size = newSize
self.textView.isHidden = false
}
override func awakeFromNib() {
super.awakeFromNib()
self.backgroundColor = UIColor.clear // .blue
self.layer.cornerRadius = 10
}
}
This perfect way to do it the content comes from : https://www.youtube.com/watch?v=0Jb29c22xu8 .
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// let's create our text view
let textView = UITextView()
textView.frame = CGRect(x: 0, y: 0, width: 200, height: 100)
textView.backgroundColor = .lightGray
textView.text = "Here is some default text that we want to show and it might be a couple of lines that are word wrapped"
view.addSubview(textView)
// use auto layout to set my textview frame...kinda
textView.translatesAutoresizingMaskIntoConstraints = false
[
textView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
textView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
textView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
textView.heightAnchor.constraint(equalToConstant: 50)
].forEach{ $0.isActive = true }
textView.font = UIFont.preferredFont(forTextStyle: .headline)
textView.delegate = self
textView.isScrollEnabled = false
textViewDidChange(textView)
}
}
extension ViewController: UITextViewDelegate {
func textViewDidChange(_ textView: UITextView) {
print(textView.text)
let size = CGSize(width: view.frame.width, height: .infinity)
let estimatedSize = textView.sizeThatFits(size)
textView.constraints.forEach { (constraint) in
if constraint.firstAttribute == .height {
constraint.constant = estimatedSize.height
}
}
}
}
i builded a static tableview with more Rowes than the screen has, so the user has to scroll to see all cell.
Every cell has a textfield with the following class to add a bottom border:
class TextFieldWithBottomBorder: UITextField {
let border = CALayer()
let width = CGFloat(1.0)
func addBottomBorder(color: UIColor){
self.border.borderColor = color.cgColor
self.border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height:self.frame.size.height)
self.border.borderWidth = self.width
self.layer.addSublayer(self.border)
self.layer.masksToBounds = true
}
func changeBorderColor(color: UIColor){
self.border.borderColor = color.cgColor
}
}
And i call the method after receiving some data from the server e. g.
self.firstnameTextField.text = firstNameFromDB
self.firstnameTextField.addBottomBorder(color: .blue)
This works fine for every cell is currently displayed. But the cells which are out of the current view the with is shorter than the textfield.
See this screenshot, for "Vorname", means firstName everything looks good, but for email, password etc. the border is to short.

Looks like the size of the UITextField is being resized after you have called addBottomBorder and so the UIView being used at the line is now not wide enough. It's difficult to say why this would be without seeing more code but there are several methods you could use to overcome it.
1) Switch to a UIView instead of a CALayer and use auto layout to keep the view in the correction position.
2) Override layoutSubviews to update the frame of the bottom line.
The simplest for you is probably option 2 (although I would go option 1) and it would look like this:
override func layoutSubviews() {
super.layoutSubviews()
self.border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height:self.frame.size.height)
}
Now whenever the frame/size of the text field changes the frame/size of the border line CALayer will be updated appropriately.
Use this class for bottom line text field
#IBDesignable class BottomTextField: UITextField {
var lineView = UIView()
#IBInspectable var lineViewBgColor:UIColor = UIColor.gray{
didSet {
if !isFirstResponder {
lineView.backgroundColor = lineViewBgColor
}
}
}
required init?(coder aDecoder:NSCoder) {
super.init(coder:aDecoder)!
setup()
}
override init(frame:CGRect) {
super.init(frame:frame)
setup()
}
// MARK:- Private Methods
private func setup() {
lineView.frame = CGRect(x:CGFloat(0), y:self.frame.size.height-2, width:self.frame.size.width, height:CGFloat(1))
lineView.backgroundColor = lineViewBgColor
self.addSubview(lineView)
}
}
How do I turn a rectangular image view into a circular image view that can hold shape in auto layout without setting width and height restraints? Thereby allowing the imageView to define it’s size, and size bigger and smaller relative to objects around it with leading, trailing, top, and bottom constraints.
I asked a similar question the other day, but I think this might be posed in a more concise way. Thanks so much!
EDIT
Ok, I started over to make this as simple as possible. I have a view named "Cell" and a UIImageView named "dog" within the cell, and that's it. I don't have "unable to simultaneously satisfy constraints" in the console anymore, just two simple views using auto layout. I'm still trying to use this code to round the UIImageView:
profileImageView.layer.cornerRadius = profileImageView.frame.size.width / 2
profileImageView.clipsToBounds = true
Here is the cell constraint setup:
Here is the profile pic constraint setup:
Here is the result without the code, no rounding, but nice and square:
Here is the result with the code to round:
This makes no sense to me, because without the rounding code the image is square, and with the code it's diamond shaped. If it's square shouldn't it be a circle with no issues?
EDIT 2
Here's what happens when I remove the bottom constraint and add a multiplier of .637 for equal height to superview.
Unfortunately you cannot do this using cornerRadius and autolayout — the CGLayer is not affected by autolayout, so any change in the size of the view will not change the radius which has been set once causing, as you have noticed, the circle to lose its shape.
You can create a custom subclass of UIImageView and override layoutSubviews in order to set the cornerRadius each time the bounds of the imageview change.
EDIT
An example might look something like this:
class Foo: UIImageView {
override func layoutSubviews() {
super.layoutSubviews()
let radius: CGFloat = self.bounds.size.width / 2.0
self.layer.cornerRadius = radius
}
}
And obviously you would have to constrain the Foobar instance's width to be the same as the height (to maintain a circle). You would probably also want to set the Foobar instance's contentMode to UIViewContentMode.ScaleAspectFill so that it knows how to draw the image (this means that the image is likely to be cropped).
Setting radius in viewWillLayoutSubviews will solve the problem
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
profileImageView.layer.cornerRadius = profileImageView.frame.height / 2.0
}
create new interface in your .h file like
#interface CornerClip : UIImageView
#end
and implementation in .m file like
#implementation cornerClip
-(void)layoutSubviews
{
[super layoutSubviews];
CGFloat radius = self.bounds.size.width / 2.0;
self.layer.cornerRadius = radius;
}
#end
now just give class as "CornerClip" to your imageview.
100% working... Enjoy
First of all, I should mention that u can get a circle shape for your UIView/UIImageView only if the width and height will be equal. It's important to understand. In all other cases (when width != height), you won't get a circle shape because the initial shape of your UI instance was a rectangle.
OK, with this so UIKit SDK provides for developers a mechanism to manipulate the UIview's layer instance to change somehow any of layer's parameters, including setting up a mask to replace the initial shape of UIView element with the custom one. Those instruments are IBDesignable/IBInspectable. The goal is to preview our custom views directly through Interface Builder.
So using those keywords we can write our custom class, which will deal only with the single condition whether we need to round corners for our UI element or not.
For example, let's create the class extended from the UIImageView.
#IBDesignable
class UIRoundedImageView: UIImageView {
#IBInspectable var isRoundedCorners: Bool = false {
didSet { setNeedsLayout() }
}
override func layoutSubviews() {
super.layoutSubviews()
if isRoundedCorners {
let shapeLayer = CAShapeLayer()
shapeLayer.path = UIBezierPath(ovalIn:
CGRect(x: bounds.origin.x, y: bounds.origin.y, width: bounds.width, height: bounds.height
)).cgPath
layer.mask = shapeLayer
}
else {
layer.mask = nil
}
}
}
After setting the class name for your UIImageView element (where the dog picture is), in your storyboard, you will get a new option, appeared in the Attributes Inspector menu (details at the screenshot).
The final result should be like this one.
It seems when you add one view as a subview of another that netted view will not necessarily have the same height as its superview. That's what the problem seems like. The solution is to not add your imageView as a subview, but have it on top of your backgroundView. In the image below I'm using a UILabel as my backgroundView.
Also in your case, when you're setting the cornerRadius use this: let radius: CGFloat = self.bounds.size.height / 2.0.
With my hacky solution you'll get smooth corner radius animation alongside frame size change.
Let's say you have ViewSubclass : UIView. It should contain the following code:
class ViewSubclass: UIView {
var animationDuration : TimeInterval?
let imageView = UIImageView()
//some imageView setup code
override func layoutSubviews() {
super.layoutSubviews()
if let duration = animationDuration {
let anim = CABasicAnimation(keyPath: "cornerRadius")
anim.fromValue = self.imageView.cornerRadius
let radius = self.imageView.frame.size.width / 2
anim.toValue = radius
anim.duration = duration
self.imageView.layer.cornerRadius = radius
self.imageView.layer.add(anim, forKey: "cornerRadius")
} else {
imageView.cornerRadius = imageView.frame.size.width / 2
}
animationDuration = nil
}
}
An then you'll have to do this:
let duration = 0.4 //For example
instanceOfViewSubclass.animationDuration = duration
UIView.animate(withDuration: duration, animations: {
//Your animation
instanceOfViewSubclass.layoutIfNeeded()
})
It's not beautiful, and might not work for complex multi-animations, but does answer the question.
Swift 4+ clean solution based on omaralbeik's answer
import UIKit
extension UIImageView {
func setRounded(borderWidth: CGFloat = 0.0, borderColor: UIColor = UIColor.clear) {
layer.cornerRadius = frame.width / 2
layer.masksToBounds = true
layer.borderWidth = borderWidth
layer.borderColor = borderColor.cgColor
}
}
Sample usage in UIViewController
1.Simply rounded UIImageView
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
imageView.setRounded()
}
2.Rounded UIImageView with border width and color
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
imageView.setRounded(borderWidth: 1.0, borderColor: UIColor.red)
}
write this code
override viewDidLayoutSubViews() {
profileImageView.layer.cornerRadius = profileImageView.frame.size.width / 2
profileImageView.clipsToBounds = true
}
in this case it will called after calculating the autolayout calculations in the first code you called the cornerradius code before calculating the actual size of the view cuz it's dynamically calculated using aspect ratio , the actual corner radius is calculated before equaling the width and the height of the view
I have same problem, and Now I get what happened here, hope some ideas can help you:
there are something different between the tows:
your profileImageView in storyboard
your profileImageView in viewDidLoad
the size of bound and frame is different when viewDidLoad and in storyboard,just because view is resize for different device size.
You can try it print(profileImageView.bounds.size) in viewDidLoad and viewDidAppear you will find the size in viewDidLoad you set cornerRadius is not the real "running" size.
a tips for you:
you can use a subClass of ImageView to avoid it, or do not use it in storyboard,
If you have subclassed the UIImageView. Then just add this piece of magical code in it.
Written in : Swift 3
override func layoutSubviews() {
super.layoutSubviews()
if self.isCircular! {
self.layer.cornerRadius = self.bounds.size.width * 0.50
}
}
I am quite new to iOS native development, but I had the same problem and found a solution.
So the green background has this constraints:
backgroundView.translatesAutoresizingMaskIntoConstraints = false
backgroundView.topAnchor.constraint(equalTo: superview!.safeAreaLayoutGuide.topAnchor).isActive = true
backgroundView.leftAnchor.constraint(equalTo: superview!.leftAnchor).isActive = true
backgroundView.widthAnchor.constraint(equalTo: superview!.widthAnchor).isActive = true
backgroundView.heightAnchor.constraint(equalTo: superview!.heightAnchor, multiplier: 0.2).isActive = true
The image constraints:
avatar.translatesAutoresizingMaskIntoConstraints = false
avatar.heightAnchor.constraint(equalTo: backgroundView.heightAnchor, multiplier: 0.8).isActive = true
avatar.widthAnchor.constraint(equalTo: backgroundView.heightAnchor, multiplier: 0.8).isActive = true
avatar.centerYAnchor.constraint(equalTo: backgroundView.centerYAnchor, constant: 0).isActive = true
avatar.leadingAnchor.constraint(equalTo: backgroundView.leadingAnchor, constant: 20).isActive = true
on viewWillLayoutSubviews() method I set the corner radius
to
avatar.layer.cornerRadius = (self.frame.height * 0.2 * 0.8) / 2
Basically, I am simply calculating the height of the image and then divide it by 2. 0.2 is the backgroungView height constraint multiplier and 0.8 the image width/height constraint multiplier.
Solution: Crop the image
[imageView setImage:[[imageView image] imageWithRoundedCorners:imageView.image.size.width/2]];
imageView.contentMode = UIViewContentModeScaleAspectFill;
I was looking for the same solution for profile pictures. After some hit and try and going through available functions, I came across something which works and is a nice way to ensure its safe. You can use the following function to crop out a round image from the original image and then you need not worry about the corner radius.
Post this even if your view size changes the image remains round and looks good.
Add a 1:1 aspect ratio constraint to the imageView for it to remain circular, despite any height or width changes.
I added custom IBInspectable cornerRadiusPercent, so you can do it without any code.
class RoundButton: UIButton {
override var bounds: CGRect {
didSet {
updateCornerRadius()
}
}
//private var cornerRadiusWatcher : CornerRadiusPercent?
#IBInspectable var cornerRadiusPercent: CGFloat = 0 {
didSet {
updateCornerRadius()
}
}
func updateCornerRadius()
{
layer.cornerRadius = bounds.height * cornerRadiusPercent
}
}
Can be easily done by creating an IBOutlet for the constraint which needs to be changed at runtime. Below is the code:
Create a IBOutlet for the constraint that needs to be changed at run time.
#IBOutlet var widthConstraint: NSLayoutConstraint!
Add below code in viewDidLoad():
self.widthConstraint.constant = imageWidthConstraintConstant()
Below function determines for device types change the width constraint accordingly.
func imageWidthConstraintConstant() -> CGFloat {
switch(self.screenWidth()) {
case 375:
return 100
case 414:
return 120
case 320:
return 77
default:
return 77
}
}
Basing on the source code below:
#IBOutlet var myUIImageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
self.makingRoundedImageProfileWithRoundedBorder()
}
private func makingRoundedImageProfileWithRoundedBorder() {
// Making a circular image profile.
// self.myUIImageView.layer.cornerRadius = self.myUIImageView.frame.size.width / 2
// Making a rounded image profile.
self.myUIImageView.layer.cornerRadius = 20.0
self.myUIImageView.clipsToBounds = true
// Adding a border to the image profile
self.myUIImageView.layer.borderWidth = 10.0
self.myUIImageView.layer.borderColor = UIColor.whiteColor().CGColor
}
Indeed I am able to render a circular or rounded UIImageView, but the problem is that if we add the border, the image leaks a bit. It's way worse with a circular UIImageView, it leaks whenever the border is bent, so LEAKS EVERYWHERE! You can find a screenshot of the result below:
Any way to fix that in Swift? Any sample code which answers to this question will be highly appreciated.
Note: as far as possible the solution has to be compatible with iOS 7 and 8+.
First Solution
Basing on the #Jesper Schläger suggestion
"If I may suggest a quick and dirty solution:
Instead of adding a border to the image view, you could just add another white view below the image view. Make the view extend 10 points in either direction and give it a corner radius of 20.0. Give the image view a corner radius of 10.0."
Please find the Swift implementation below:
import UIKit
class ViewController: UIViewController {
#IBOutlet var myUIImageView: UIImageView!
#IBOutlet var myUIViewBackground: UIView!
override func viewDidLoad() {
super.viewDidLoad()
// Making a circular UIView: cornerRadius = self.myUIImageView.frame.size.width / 2
// Making a rounded UIView: cornerRadius = 10.0
self.roundingUIView(self.myUIImageView, cornerRadiusParam: 10)
self.roundingUIView(self.myUIViewBackground, cornerRadiusParam: 20)
}
private func roundingUIView(let aView: UIView!, let cornerRadiusParam: CGFloat!) {
aView.clipsToBounds = true
aView.layer.cornerRadius = cornerRadiusParam
}
}
Second Solution
Would be to set a circle mask over a CALayer.
Please find the Objective-C implementation of this second solution below:
CALayer *maskedLayer = [CALayer layer];
[maskedLayer setFrame:CGRectMake(50, 50, 100, 100)];
[maskedLayer setBackgroundColor:[UIColor blackColor].CGColor];
UIBezierPath *maskingPath = [UIBezierPath bezierPath];
[maskingPath addArcWithCenter:maskedLayer.position
radius:40
startAngle:0
endAngle:360
clockwise:TRUE];
CAShapeLayer *maskingLayer = [CAShapeLayer layer];
[maskingLayer setPath:maskingPath.CGPath];
[maskedLayer setMask:maskingLayer];
[self.view.layer addSublayer:maskedLayer];
If you comment out from line UIBezierPath *maskingPath = [UIBezierPath bezierPath]; through [maskedLayer setMask:maskingLayer]; you will see that the layer is a square. However when these lines are not commented the layer is a circle.
Note: I neither tested this second solution nor provided the Swift implementation, so feel free to test it and let me know if it works or not through the comment section below. Also feel free to edit this post adding the Swift implementation of this second solution.
If I may suggest a quick and dirty solution:
Instead of adding a border to the image view, you could just add another white view below the image view. Make the view extend 10 points in either direction and give it a corner radius of 20.0. Give the image view a corner radius of 10.0.
I worked on improving the code but it keeps crashing. I'll work on it, but I appear to have got a (rough) version working:
Edit Updated with a slightly nicer version. I don't like the init:coder method but maybe that can factored out/improved
class RoundedImageView: UIView {
var image: UIImage? {
didSet {
if let image = image {
self.frame = CGRect(x: 0, y: 0, width: image.size.width/image.scale, height: image.size.width/image.scale)
}
}
}
var cornerRadius: CGFloat?
private class func frameForImage(image: UIImage) -> CGRect {
return CGRect(x: 0, y: 0, width: image.size.width/image.scale, height: image.size.width/image.scale)
}
override func drawRect(rect: CGRect) {
if let image = self.image {
image.drawInRect(rect)
let cornerRadius = self.cornerRadius ?? rect.size.width/10
let path = UIBezierPath(roundedRect: rect, cornerRadius: cornerRadius)
UIColor.whiteColor().setStroke()
path.lineWidth = cornerRadius
path.stroke()
}
}
}
let image = UIImage(named: "big-teddy-bear.jpg")
let imageView = RoundedImageView()
imageView.image = image
Let me know if that's the sort of thing you're looking for.
A little explanation:
As I'm sure you've found, the "border" that iOS can apply isn't perfect, and shows the corners for some reason. I found a few other solutions but none seemed to work. The reason this is a subclass of UIView, and not UIImageView, is that drawRect: is not called for subclasses of UIImageView. I am not sure about the performance of this code, but it seems good from my (limited) testing
Original code:
class RoundedImageView: UIView {
var image: UIImage? {
didSet {
if let image = image {
self.frame = CGRect(x: 0, y: 0, width: image.size.width/image.scale, height: image.size.width/image.scale)
}
}
}
private class func frameForImage(image: UIImage) -> CGRect {
return CGRect(x: 0, y: 0, width: image.size.width/image.scale, height: image.size.width/image.scale)
}
override func drawRect(rect: CGRect) {
if let image = self.image {
self.image?.drawInRect(rect)
let path = UIBezierPath(roundedRect: rect, cornerRadius: 50)
UIColor.whiteColor().setStroke()
path.lineWidth = 10
path.stroke()
}
}
}
let image = UIImage(named: "big-teddy-bear.jpg")
let imageView = RoundedImageView()
imageView.image = image
imageView.layer.cornerRadius = 50
imageView.clipsToBounds = true
