   -(void)layoutSubviews
     {
[super layoutSubviews];
self.backgroundColor = [UIColor clearColor];
self.contentView.layer.cornerRadius =5;
self.contentView.layer.masksToBounds = YES;

 }

i have applied this above code to my cell class file

回答1:

In cellForRowAtIndexPath Use

    cell.layer.cornerRadius=5

If you have different cells in different sections then make sure that this code is written for all sections

回答2:

Other Simple Option is set RuntimeAttributs in Storyboard or XIB.

first select your view(click on your view) > go to Identiti Inspector (near Attributes inspector in your Xcode right side) > User Defined Runtime Attributes > + click and Add Below two one by one in this field.

layer.cornerRadius
layer.masksToBounds

Clean and build your project. not need to code any .h or .m file.

For me it's works perfectly, maybe my code helps to somebody.

NSInteger rowsAmount = [tableView numberOfRowsInSection:indexPath.row];
if (rowsAmount) {

    UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:cell.bounds byRoundingCorners:( UIRectCornerBottomLeft | UIRectCornerBottomRight | UIRectCornerTopLeft | UIRectCornerTopRight) cornerRadii:CGSizeMake(10.0, 10.0)];

    CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
    maskLayer.frame = self.view.bounds;
    maskLayer.path  = maskPath.CGPath;

    cell.layer.mask = maskLayer;

}

Try this code in awakeFromNib:()

self.backgroundColor = [UIColor clearColor];
self.contentView.layer.cornerRadius =5;
self.contentView.layer.masksToBounds = YES;

回答5:

Here's a different approach : In your cellForRow just before returning the cell you can try out the following code :

CGFloat corner = 20.0f;
UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:cell.backgroundView.bounds byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(corner, corner)];
CAShapeLayer  *shapeLayer = (CAShapeLayer *)cell.backgroundView.layer;
shapeLayer.path = path.CGPath;
shapeLayer.fillColor = cell.textLabel.backgroundColor.CGColor;
shapeLayer.strokeColor = [UIColor lightGrayColor].CGColor;
shapeLayer.lineWidth = 1.0f;

Let me know !

Swift 4 :

override func layoutSubviews() {
    super.layoutSubviews()

    self.contentView.clipsToBounds = true
    self.contentView.layer.cornerRadius = 5

}
