I have UIImages that I show in a UIImageView. The UIImageView has the
contentMode = .scaleAspectFit
property. The UIImages show just fine on the UIImageView, but I want to edit the UIImages so that they don't have any blank (transparent) space, and instead fill the blank spaces with a black color, and I want it to do this dynamically, depending on the end-users screen size.
Example:
What I want to do is replace the areas I've drawn in, with a black color, and save it as an UIImage.
Simply set backgroundcolor for the uiimageview
Set the background Color of the imageView to black
Using imageView outlet
self.imageView.backgroundColor = UIColor.black
Using IB
Set black color for imageview as well as set frame equal to frame of main view.
self.imageView.backgroundColor = UIColor.black
For AutoRisize:
self.imageView.frame = self.view.frame
For AutoLayout:
Set leading, trailing, top and bottom constraints with main view (self.view)

I want to achieve label/Button embededd in UIImageView in iOS Swift like shown in image.Has anyone done that?
You just need to play with UIView, UILabel And UIImageView.
You view hierarchy will be like below...
- UIView (mainView)
- UIImageView (imageView)
- UILabel
You need to make mainView.clipsToBounds = true so that after giving corner radius to it, it's subview will not go beyond its superview's bounds.
For imageView, you can set its content mode to aspect fill/ aspect fit as per your requirement.
Have a square UIView with clipsToBounds property set to YES which contains UIImageView and UILabel. The image view should cover all the view frame. The label should be positioned at the bottom of the view over the image view. Then just set appropriate corner radius (half of the view's height) for the view's layer and set its masksToBounds property to YES. That's it
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 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 have a UIImageView which is set to mode Aspect Fit. Now I want to place an edit button on top right corner of that image view. I am using auto layout and have a constraint of (Button->Trailing Space to superview) and the layout is connected via IBOutlet.
Once the image is set in UIImageView, I want to resize the ImageView Frame, so I can place the UIButton on top right. But UIImageView is not resizing as per image. Look at the gray part in the attached image (It is the background of ImageView)
imageView.clipsToBounds = YES;
imageView.image = image;
[imageView sizeToFit];
buttonLeadingSpace.constant = imageView.frame.origin.x+imageView.frame.size.width-44;
First of all, you should align your button with ImageView top & trailing. you can add constant=padding you need for your button.
UIImage is displaying as per your properties set for UIImageView (ie. contentMode = AspectFit). Here are the few options you might be interested in
If you want to fill the complete width just remove the height constraint from the UIImageView. It will fill the width and increase the UIImageView height as per image aspect ratio.
If you want same height and width of UIImageView set contentMode = aspectFit. this will fill the complete UIImageView but might clip the image.
Remove leading and trailing constraints from UIImageView. Align horizontal center and add image width constraint.
I have image with size 10x10 px and I need to set the image as background for UIView with the image copied horizontally and vertical, not stretched. Is it possible to do with ios?
you can do it like this:
view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"bodyBG"]];
It copied horizontally and vertical in default.
