How to change UITableViewCell Image to Circle in UITableView - ios

Question

My code works for the most part.
The issue I am having is the images start out as square, and change to circle when I scroll the table or refresh it.
What am I missing?
Here's my code:
cell.imageView.layer.cornerRadius = cell.imageView.frame.size.width / 2.0;
cell.imageView.layer.borderWidth = 3.0;
cell.imageView.layer.borderColor = [UIColor colorWithRed:157.0/255.0 green:34.0/255.0 blue:53.0/255.0 alpha:1.0]
.CGColor;
cell.imageView.clipsToBounds = YES;
NSDictionary *tweet = (self.results)[indexPath.row];
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSString * imageString = [tweet valueForKeyPath:#"user.profile_image_url"];
NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:imageString]];
if (imageData != nil)
{
dispatch_async(dispatch_get_main_queue(), ^{
cell.imageView.image = [UIImage imageWithData: imageData];
[cell setNeedsLayout];
});
}
});
EDIT ---- The code is in cellForRowAtIndexPath
Right when I launch the app the cell images are square. If I pullToRefresh the change to round or if I start scrolling the table they change to round.
EDIT TWO
Another issue I am seeing is the images change as I scroll.
How do I prevent this?

In order if anyone having this problem, here is the solution in
Swift
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:ContactCellTableViewCell? = tableView.dequeueReusableCellWithIdentifier("contactCell", forIndexPath: indexPath) as? ContactCellTableViewCell
var contact : ContactStruct
image = searchResults[indexPath.row]
let newImage = resizeImage(image, toTheSize: CGSizeMake(70, 70))
var cellImageLayer: CALayer? = cell?.imageView.layer
cellImageLayer!.cornerRadius = 35
cellImageLayer!.masksToBounds = true
cell?.imageView.image = newImage
return cell!
}
As you might noticed the 35 hardcode is basically half of the image size which is 70 in here.
And here is the resize function:
func resizeImage(image:UIImage, toTheSize size:CGSize)->UIImage{
var scale = CGFloat(max(size.width/image.size.width,
size.height/image.size.height))
var width:CGFloat = image.size.width * scale
var height:CGFloat = image.size.height * scale;
var rr:CGRect = CGRectMake( 0, 0, width, height);
UIGraphicsBeginImageContextWithOptions(size, false, 0);
image.drawInRect(rr)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext();
return newImage
}
Note: I am using a custom cell class as below:
import UIKit
class ContactCellTableViewCell: UITableViewCell {
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var contactImage: UIImageView!
#IBOutlet weak var phoneLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
It really took me a while to figure this one out. The images become rounded after scrolling at first, but now using this code you are going to have the rounded images inside the cell from beginning.
Hope it helped anyone.

Try this in override-
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// image Width(84) / 2 = 42
cell.CellImage.layer.cornerRadius = 42.0
cell.CellImage.layer.masksToBounds = true
//or
cell.CellImage.layer.cornerRadius = cell.CellImage.frame.width / 2
cell.CellImage.clipsToBounds = true
}

Most likely the cell's frame (and hence the imageView's frame) isn't set the very first time the cell is created. So setting the imageView's layer's cornerRadius based on that initial frame doesn't work. The best solution is to implement the tableView:willDisplayCell:forRowAtIndexPath: delegate method and set the layer there:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.imageView.layer.cornerRadius = cell.imageView.frame.size.width / 2.0;
}

Answer 4

Its simple..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.ImageView.layer.cornerRadius = 150.0f;
cell.ImageView.layer.borderWidth = 2.0f;
cell.ImageView.layer.borderColor = [UIColor blackColor].CGColor;
cell.ImageView.clipsToBounds = YES;
}

Create a custom cell, and add an image view (with an IBOutlet), sized and positioned however you want (the outlet is "iv" in my example below). Put the code to make image view round in the awakeFromNib method (assuming your cell is created in a nib or storyboard).
-(void)awakeFromNib {
self.iv.layer.cornerRadius = self.iv.frame.size.width / 2.0;
self.iv.layer.borderWidth = 3.0;
self.iv.layer.borderColor = [UIColor colorWithRed:157.0/255.0 green:34.0/255.0 blue:53.0/255.0 alpha:1.0].CGColor;
self.iv.clipsToBounds = YES;
}

I had a similar issue, my UIImageView was initially a square and would only show as circular when the UITableViewCell it was within was either highlighted or selected.
It was a simple fix:
Swift 2.0
imgView.layer.cornerRadius = imgView.frame.width / 2
imgView.clipsToBounds = true
This was placed inside the awakeFromNib() for my custom UITableViewCell.
This is assuming imgView is the name of the UIImageView hooked up via storyboard inside this custom UITableViewCell.

Answer 7

#interface MyCell : UITableViewCell
#end
#implementation MyCell
- (void)awakeFromNib
{
[super awakeFromNib];
self.imageView.layer.masksToBounds = YES;
self.textLabel.font = [UIFont systemFontOfSize:17];
self.textLabel.textColor = [UIColor darkTextColor];
}
// --- image view frame is empty rect inside tableView: willDisplayCell:
// +++ set cornerRadius inside layoutSubviews works.
- (void)layoutSubviews
{
[super layoutSubviews];
// layout image view
CGRect vfr = self.frame;
CGRect imgvr = self.imageView.frame;
imgvr.origin.x = 16;
imgvr.size.width = CGRectGetHeight(vfr);
self.imageView.frame = imgvr;
// update corner radius
self.imageView.layer.cornerRadius = imgvr.size.width * 0.5f;
// layout label
CGRect lblr = self.textLabel.frame;
lblr.origin.x = CGRectGetMaxX(imgvr) + 16;
lblr.size.width = CGRectGetWidth(vfr) - CGRectGetMaxX(imgvr) - 32;
self.textLabel.frame = lblr;
}
#end

Answer 8

In case your cell is by code:
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
let myImageView = (cell as! MyCustomCell).myImageView
myImageView.layoutIfNeeded()
myImageView.layer.cornerRadius = myImageView.frame.width / 2.0
}

Answer 9

cell.imageView?.layer.cornerRadius = 22.0
cell.imageView?.layer.masksToBounds = true

Set the image view to a circle inside the async call where you set the image.
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSString * imageString = [tweet valueForKeyPath:#"user.profile_image_url"];
NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:imageString]];
if (imageData != nil)
{
dispatch_async(dispatch_get_main_queue(), ^{
cell.imageView.image = [UIImage imageWithData: imageData];
cell.imageView.layer.cornerRadius = cell.imageView.frame.size.width / 2.0;
cell.imageView.layer.borderWidth = 3.0;
cell.imageView.layer.borderColor = [UIColor colorWithRed:157.0/255.0 green:34.0/255.0 blue:53.0/255.0 alpha:1.0]
.CGColor;
cell.imageView.clipsToBounds = YES;
[cell setNeedsLayout];
});
}
});

Here is a perfect and state away solution for circular image in UITableview Cell.
Simply modify your UITableviewCell (custom cell) class with below code.
override func awakeFromNib() {
super.awakeFromNib()
imgEvent.layer.frame = (imgEvent.layer.frame).insetBy(dx: 0, dy: 0)
imgEvent.layer.borderColor = UIColor.gray.cgColor
imgEvent.layer.cornerRadius = (imgEvent.frame.height)/2
imgEvent.layer.masksToBounds = false
imgEvent.clipsToBounds = true
imgEvent.layer.borderWidth = 0.5
imgEvent.contentMode = UIViewContentMode.scaleAspectFill
}
It will also helps to solve the problem of image circular only after scrolling table..(if any)
