With my project I use the following code in order to make my images in rounded shape:
profileImage.layer.cornerRadius = profileImage.frame.size.width / 2
profileImage.clipsToBounds = true
I also use contrains for my image to make it width = hight, and other constrains.
After ugrading my project to xcode 8 beta, and swift 3. All the images views that I set to rounded were disappeared, and when I remove the code for making it rounded or I remove all the constrains they appear again.
But I still need them to be rounded. Anyone can help me to fix the issue.
Thanks
I had the same problem, the solution was just to move a line of code before your layer modifications.
Try to apply layout changes:
self.view.layoutIfNeeded()
before your code:
profileImage.layer.cornerRadius = profileImage.frame.size.width/2
profileImage.clipsToBounds = true
OR
place your code related to frames / layers into viewDidLayoutSubviews() method:
override func viewDidLayoutSubviews() {
profileImage.layer.cornerRadius = profileImage.frame.size.width/2
profileImage.clipsToBounds = true
}

I've got some square buttons that I'd like to add rounded corners to that are proportional to the button's height. In past versions of my app, I had implemented this feature without issues using viewDidLayoutSubviews(). For some reason, after pushing a new version of my app with other features I had tweaked, this section of code no longer functions as expected. Here is the code:
override func viewDidLayoutSubviews() {
for button in buttons {
button!.layer.shadowColor = UIColor.black.cgColor
button!.layer.shadowOffset = CGSize(width: 0, height: 1.0)
button!.layer.shadowOpacity = 0.4
button!.layer.shadowRadius = button!.frame.height / 40
button!.layer.cornerRadius = button!.frame.height / 10
}
Again, this block of code used to work just fine but for some reason it no longer works. What I am experiencing is much larger relative radii on smaller buttons (iPhone SE) compared to bigger buttons (iPads).
To troubleshoot, in viewDidLayoutSubviews(), I'm printing the button!.frame.height and I'm noticing that no matter what device I use the frame height is 395.5, which I believe is the correct size only on the 12.9" iPad. Therefore, the buttons look correct on the 12.9" iPad but the radii end up being too large on all of the smaller devices.
Any idea what's going on here? Why is it that they're all returning the same frame height even though they're visually very different sizes on the different devices?
I copy and pasted the above code into the viewWillAppear() method and
the problem was resolved. I then deleted the code from
viewWillAppear(), leaving me with my original code during posting of
question, and it is continuing to run as expected (working). What
could possibly be the cause of this intermittent behavior
The reason when you initialized the buttons in viewWillAppear and remove them but it still work because your button's frame did not change in the viewDidLayoutSubview method. And the viewDidLayoutSubview is invoked only controller's view is updated, rotated, or changed, which in your case it does not.
If you try to rotate your device you will see your parent view's frame changed.
For more information about view hierarchy. See this article
Try like this:-
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
for button in buttons {
button!.layer.shadowColor = UIColor.black.cgColor
button!.layer.shadowOffset = CGSize(width: 0, height: 1.0)
button!.layer.shadowOpacity = 0.4
button!.layer.shadowRadius = button!.frame.height / 40
button!.layer.cornerRadius = button!.frame.height / 10
}
I'm trying to achieve smooth round corners on imageviews. Although it's working well on non-plus devices, i can not reach my goal at plus screen devices. Incidentally, i recognize, it's not even work well on the devices that font size enlarged. I applied following code that can be found every topic.
mergedImage.image = lastImage
mergedImage.layer.masksToBounds = false
mergedImage.layer.cornerRadius = mergedImage.frame.size.height / 2
mergedImage.clipsToBounds = true
And it's results like pictures below.
It looks like the black shape changes size. This can happen when using AutoLayout for example. If that is the case, you need to calculate the corner radius each time the frame changes.
I think the best way to do this is by subclassing UIView to create a "black shape view", and then overriding its layoutSubviews method:
override func layoutSubviews() {
super.layoutSubviews()
layer.cornerRadius = bounds.height / 2
}
If you don't have a subclass, you can for example do this in UIViewController.viewDidLayoutSubviews:
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
mergedImage.layer.cornerRadius = bounds.height / 2
}
I was wondering how I can get a gap between overlaying views in swift. This is really hard for me to explain so I added a couple images to explain what I'm talking about This is the effect in iMessage The same effect in Facebook Messenger And again in facebook messenger. I am talking about the little gap of space in between the view that says the number of minutes and the profile image (in the 3rd image). I was wondering how I could achieve the same thing in Swift because I'd like to integrate this into my app. Thank you so much!
You can do this many ways.
One of the way, I am posting.
One View, UIView, that should be Square. Inside that, One UIImageView and One SmallView
Constraints as follows:
OuterView: width & height be 120, top 50, and Center Horizontally
ImageView = { 4,4,4,4 },
SmallView = right and bottom as 0, width and height be 40 [Square]
PlusSignImgVw = { 4,4,4,4 }
Like below:
Coding:
override func viewDidAppear(_ animated: Bool) {
imageVw.layer.cornerRadius = imageVw.frame.size.width / 2
smallSquareView.layer.cornerRadius = smallSquareView.frame.size.width / 2
smallSquareView.clipsToBounds = true
plusSign.layer.cornerRadius = plusSign.frame.size.width / 2
plusSign.clipsToBounds = true
}
Output:
It's a bit tricky, not obvious at first, but not too difficult either.
For the round images, try this:
customView.layer.cornerRadius = customView.bounds.size.width / 2.0
customView.layer.borderWidth = 2.0
customView.layer.borderColor = UIColor.white.cgColor
For the rectangular image with round corners, first line will calculate the .cornerRadius based on height (or you can actually do it for all the cases, and it would also work):
customView.layer.cornerRadius = customView.bounds.size.width / 2.0
Just replace customView with yourCustomViewName and write those 3 lines for each view. That should do the job.
I have been trying to make the UIButton in the cells a perfect circle. Unfortunately the circle has been formed based on the background image rather than the UIButton frame.
The code I have for creating a circle:
cell.StoryViewButton.setImage(image, forState: .Normal)
cell.StoryViewButton.frame = CGRectMake(50, 8, 100, 100)
cell.StoryViewButton.layer.masksToBounds = false
cell.StoryViewButton.layer.cornerRadius = cell.StoryViewButton.frame.width/2
cell.StoryViewButton.clipsToBounds = true
The output looks like this:
What can I do to get the perfect circle button frames that I want?
Try something like this
cell.StoryViewButton.layer.masksToBounds = true
cell.StoryViewButton.layer.cornerRadius = cell.StoryViewButton.frame.width/2
If you need to create a circle of view you have to set masksToBounds to true, do not set clipsToBounds
Hope this will help you.
Swift 4
You could apply the following function to any view, including buttons.
func makeViewCircular(view: UIView) {
view.layer.cornerRadius = view.bounds.size.width / 2.0
view.clipsToBounds = true
}
Great.
That didn't work for me at first as I applied it in the viewDidLoad, though. At this point, constraints are still playing with the size of your buttons and the corner radius is applied to a button it thinks is twice the size, resulting in the odd shapes you have. To apply the right values to the right measurements, place the code in override func viewDidLayoutSubviews().
I know this may be a more specific case within my personal process, yet I'm sure it'll help somebody.
There is the working code.I test it. Hope it helps.
I am not sure why but I check that by changing height and width of the frame in here "CGRectMake(50, 8, 120, 120)" that the height and width of the frame and height and width of a button should be same to get the perfect circle.
cell.StoryViewButton.setImage(image, forState: .Normal)
cell.StoryViewButton.frame = CGRectMake(50, 8, 120, 120)
cell.StoryViewButton.layer.cornerRadius = self.btn.frame.width/2;
cell.StoryViewButton.layer.masksToBounds = true
Hope it helps.
I'm simply trying to create a perfectly round image. Here's my swift code:
myImage.layer.cornerRadius = myImage.frame.size.width/2
myImage.layer.masksToBounds = true
This works on a 4s, but is not quite round on a 5s, and appears as a rounded rectangle on a iphone 6.
I'm assuming this has to do with frame.size.width returning values in pixels not points or something like that, but I've been unable to solve this problem.
If you're putting that code in viewDidLoad, try moving it to viewDidLayoutSubviews.
I'm guessing it's an auto layout issue -- although you've used the corner radius property appropriately and are in fact making the image frame circular, after auto-layout, the corner radius stays the same, but the image stretches so that it's no longer circular.
If your code is in viewDidLoad in ViewController, try moving it to viewDidLayoutSubviews.
If your rounded imageView is in tableViewCell, try moving it to draw.
override func draw(_ rect: CGRect) {
avatarView.layer.cornerRadius = avatarView.frame.size.width / 2
avatarView.layer.masksToBounds = true
avatarView.clipsToBounds = true
avatarView.contentMode = .scaleAspectFill
}
The problem is that if you change the cornerRadius of Any view, and expect it to look like a circle, the view has to be a square.
Now, because of different devices and different device size, the size of your image view might change and it may be a rectangle.
For e.g.
If you view is a 50 * 50
myImage.layer.cornerRadius = myImage.frame.size.width/2
This would add corner radios of 25 on both sides to make it a circle.
But because of auto layout of device change, your view might be a 50 * 80
Corner radius would add a 25, but as the height is 80, it will add 25 on both sides, and the remaining 30 won't be a curve and look straight.
What you can do is try viewing the screen in various orientations in the storyboard and change auto layout Constraints (Or structs and springs) to ensure that the image view is a square in all the devices
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
myImage.layer.cornerRadius = myImage.frame.size.width/2
myImage.layer.masksToBounds = true
}
This should work:
myImage.layer.cornerRadius = myImage.**bounds**.size.width/2
myImage.layer.masksToBounds = true
