I wanted to circle my UIImageView and added this code :
profileImage.layer.cornerRadius = profileImage.frame.size.height/2
profileImage.clipsToBounds = true
and it work perfectly, but when images are horizontal, I get this picture:
as you can see, there is white space at the bottom and top of my circle image view. but what I really wanted was a circle filled with my image!
I've tried changing "content Mode" from attribute inspector, but I didn't get any answer! how can I fix this issue?
You have already set the clipsToBound property. So just update the contentMode.
I you don't want to distort image's scale:
profileImage.contentMode = .scaleAspectFill
If image's scale does not matter, you also can use:
profileImage.contentMode = .scaleToFill
Follow the link for more details: https://useyourloaf.com/blog/stretching-redrawing-and-positioning-with-contentmode/
Use below code:-
profileImage.clipsToBounds = true
profileImage.contentMode = .scaleAspectFill
Set the contentMode of your UIImageView to scaleAspectFill
profileImage.contentMode = .scaleAspectFill
Keep in mind that using this contentMode option some portion of the content may be clipped to fill the view’s bounds.
You can set the Different Content Mode as per you choice from StoryBoard:
You can select
Scale to Fill
Aspect Fill
or any other content mode by using trial and Error method which suits you
Hope it Helps.
If I choose Aspect Fit, I'm getting blank space in top and bottom of the imageview.
Can I trim that space anyhow?
Is there any programatically constraints I can set to re-scale imageview according to actual image size?

I am trying to set the contentMode of a UIImageView to be .top, that is contained within a UIView, but it's not set properly or runs out of the boundary of the UIView.
This is what my cell looks like with the red being the container UIView with constraints of the UIImageView:
FYI: The UIImageView is a square size because it will be applied with rounded corners.
What I've attempted to do and the result:
1.
thumbnail.contentMode = .top
thumbnail.clipsToBounds = true
thumbnail.sizeToFit()
2.
thumbnail.contentMode = .top
thumbnail.clipsToBounds = true
also tried adding:
thumbnailContainer.clipsToBounds = true
thumbnailContainer.sizeToFit()
What I'm trying to achieve is the result of the first screenshot with the UIImageView contained inside its container view as seen in the second screenshot.
UPDATE:
Based on the comments and answer, I believe some are confused on what exactly I'm trying to do, so I've attached another screenshot of the result I'm expecting :
As you can see, I want the contentMode of the UIImageView to be .top such that the top-middle of the image is displayed. You can clearly see the difference between the contentMode in the 3rd screenshot, which is .scaleAspectFit, versus the contentMode in the 4th screenshot, which is .top because it is showing the top-middle of the image.
However, I would like the UIImageView to maintain its original size, as seen in the 3rd screenshot where the contentMode is .scaleAspectFit, instead of being stretched out horizontally and vertically, as seen in the 2nd screenshot.
I hope this clarifies what I'm trying to achieve.
To achieve the result you want, you need to set content mode to .aspectFit, so that image will resize itself in UIImageView's size, keeping its original height to width ratio.
This is the cell I created by XIB:
But however, after I use tableView load the cells, I get the issue:
You need to change image scale as below :
imageView.contentMode = UIViewContentModeScaleAspectFit;
Swift 3
imageView.contentMode = .scaleAspectFit
It is because you used Aspect Fill in the attribute pannel. Thus the image width equal to the screen (as per your constraints) and keep its width*height ratio, but it is going outside bounds of your imageView.
You need to add in viewDidLoad or in your class file:
imageView.clipsToBounds = true
Check this link to Apple's documentations
you need to clip the image out side bounds:
imageView.clipsToBounds = YES
it will crop image to visible rect only
If you design your cell in xib, you can set the Clip to Bounds in Drawing:
I am displaying images in a UITableViewController inside a cell, currently to show the full image I am setting the UIImageView as aspectFit but it doesn't fill up the entire UIImageView.
Is there a way, where I can show the full image and not distort it like the other contentView modes do?
Hope this will help :)
YourImageview.contentMode = UIViewContentModeScaleAspectFill;
YourImageview.clipsToBounds = true
You should use as below :
Youreimageview.contentMode = UIViewContentModeScaleAspectFit;
This is from the This apple Document:
UIViewContentModeScaleAspectFit
The option to scale the content to fit the size of the view by
maintaining the aspect ratio. Any remaining area of the view’s bounds
is transparent.
For the Image showing in the Tableviewcell. You need to do customization of the UItableviewCell, and then you need to put imageview in that. That imageview must have this content mode to set image.
I'm trying to set the background image of a UIView with animated .gif's that I'm pulling form Giphy.
The problem I'm having is that the UIView is stretching the image. I want to fill the background so the height is 100% and have it centered. So left and right of the .gif would be cut off - but the image would be centered on the screen and not stretched.
Here's a screenshot of what it looks like now.
You can see it's fills height correct but it's shrinking the width of the image to match the UIView dimensions making it look stretched.
Here is the code I have now:
override func viewDidAppear(animated: Bool) {
self.giphyBackground(Title: "dancing") { [weak self] (gifUrl) -> Void in
let gifView = FLAnimatedImageView(frame: self!.giphy.frame)
gifView.animatedImage = FLAnimatedImage(animatedGIFData: NSData(contentsOfURL: NSURL(string: gifUrl)!)!)
self?.view.insertSubview(gifView, aboveSubview: self!.giphy)
}
}
Any ideas
I think you should set the content mode of gifView to Aspect Fit, doing so will not stretch the image and will fully fill at-least one of the length either horizontally/ vertically.
Try setting
gifView.contentMode = UIViewContentMode.ScaleAspectFit
Also you can use scale AspectFill on gifView as
gifView.contentMode = UIViewContentMode.ScaleAspectFill
ScaleAspectFill will fill the entire gifView's frame but will also maintain the aspect ratio, doing so your image won't look stretched but it could happen that content either horizontally or vertically will go outside the frame(which you can clip).
You are definitely looking for the view's contentMode ScaleAspectFit. Simply add a line gifView.contentMode=UIViewContentMode.ScaleAspectFit
in storyboard (xcode 6) i want a circular user image profile take from Facebook.
So i have make this interface in storyboard, using auto layout:
Then, using Facebook iOS sdk i take the user profile (using swift):
var facebookProfileUrl = "http://graph.facebook.com/\(userId!)/picture?type=normal";
In storyboard i have set the image to "Scale to fit" mode.
To make the image view circular i use the following code:
self.facebookProfileImage.layer.cornerRadius = self.facebookProfileImage.frame.size.width / 2;
self.facebookProfileImage.clipsToBounds = true;
When i run the code, anyway the image doesn't look circular:
I suppose the problem is auto layout but i'm not sure.
How can i make the image perfectly circular??
Two steps:
Center the UIImageView by adding a "Horizontal Center In Container" constraint (Editor > Align > Horizontal Center in Container) to the UIImageView.
Remove the leading and trailing constraints you currently have set on the UIImageView.
Why? The UIImageView is getting stretched because Auto Layout needs to account for the leading and trailing constraints you set on the UIImageView. To prove my point, set the priority of the leading and trailing constraints to something less than the priority of the height and width constraints. You should see a rounded image like you expect, but it may not be centered.
More steps:
Add aspect ratio constraint 1:1
mark check clip to bounds attribute in attribute inspector
make outlet of your view into you controller class
set corner radius to half of either its height or width
yourImageViewOutlet.layer.cornerRadius = yourImageViewOutlet.frame.size.width / 2.0
I have made the same thing a little time ago and this worked for me
self.imageView.image = [ImageHelper getImage]; //retrieve image
self.imageView.layer.cornerRadius = self.imageView.frame.size.height / 2;
self.imageView.layer.masksToBounds = YES;
self.imageView.layer.borderWidth = 0;
self.imageView.contentMode = UIViewContentModeScaleAspectFill;
SWIFT 3.x
Just change your imageView custom class with this and enjoy.
#IBDesignable class RoundedImageView:UIImageView {
#IBInspectable var borderColor:UIColor = UIColor.white {
willSet {
layer.borderColor = newValue.cgColor
}
}
override func layoutSubviews() {
super.layoutSubviews()
layer.cornerRadius = frame.height/2
layer.masksToBounds = true
layer.borderWidth = 1
layer.borderColor = borderColor.cgColor
}
}
When adding the constraint, just make sure that you check the height and width so that it will be fix. At least that what I always do.
You have given leading constraint, trailing constraint and the width constraint. So the image will try to leave 130 pixels before and after the image which will increase the width of the image.
So the solution is, remove either one of the leading or trailing constraint.
The best workaround is, remove both the constraint and add a horizontal centre constraint, that is what you want.
In storyboard i have set the image to "Scale to fit" mode
But that's a problem, isn't it? It means: "Stretch the image so that it matches the way the image view is stretched." If that isn't what you want, don't say that! Use Centered, or at least use one of the content modes with "Aspect" in its name so that your image is not stretched.
As for the circle itself, setting the cornerRadius is no way to make a circle. The way to create a circular boundary around an image is to mask the image. You can redraw the image with the circular mask as a clipping boundary, or you can apply the circular mask to the image view. (See, for example, my answer here: https://stackoverflow.com/a/16475824/341994.)
It is true that your image view is also being stretched, because you gave it constraints to both sides of the superview. You can prevent that by giving it a width constraint instead; now its width will be absolute. But you should still do the right thing on the other two issues.
