My code works for the most part.
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;
}

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;
}
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)
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
}
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
}
