自定义UITableViewCell 上面的控件设置圆角 自定义cell的drawRect 方法,并在该方法里面设置圆角
-(void)drawRect:(CGRect)rect {
[super drawRect:rect];
self.avada.layer.cornerRadius = self.avada.width * 0.5;
self.avada.layer.borderColor = [UIColor whiteColor].CGColor;
self.avada.layer.borderWidth = 2;
self.avada.layer.masksToBounds = YES;
}
section分组设置圆角
// 1:tableview 分组圆角
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
if ([cell respondsToSelector:@selector(tintColor)]) {
// if (tableView == self.tableView) {
CGFloat cornerRadius = 10.f;
cell.backgroundColor = UIColor.clearColor;
CAShapeLayer *layer = [[CAShapeLayer alloc] init];
CGMutablePathRef pathRef = CGPathCreateMutable();
CGRect bounds = CGRectInset(cell.bounds, 10, 0);
BOOL addLine = NO;
if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
CGPathAddRoundedRect(pathRef, nil, bounds, cornerRadius, cornerRadius);
} else if (indexPath.row == 0) {
CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds));
CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds), CGRectGetMidX(bounds), CGRectGetMinY(bounds), cornerRadius);
CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds));
addLine = YES;
} else if (indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds));
CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds), CGRectGetMidX(bounds), CGRectGetMaxY(bounds), cornerRadius);
CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds));
} else {
CGPathAddRect(pathRef, nil, bounds);
addLine = YES;
}
layer.path = pathRef;
CFRelease(pathRef);
//颜色修改
layer.fillColor = [UIColor colorWithWhite:1.f alpha:0.5f].CGColor;
layer.strokeColor=[UIColor blackColor].CGColor;
if (addLine == YES) {
CALayer *lineLayer = [[CALayer alloc] init];
CGFloat lineHeight = (1.f / [UIScreen mainScreen].scale);
lineLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-lineHeight, bounds.size.width-10, lineHeight);
lineLayer.backgroundColor = tableView.separatorColor.CGColor;
[layer addSublayer:lineLayer];
}
UIView *testView = [[UIView alloc] initWithFrame:bounds];
[testView.layer insertSublayer:layer atIndex:0];
testView.backgroundColor = UIColor.clearColor;
cell.backgroundView = testView;
}
// }
}
2:collection 设置分组圆角
- (void)collectionView:(UICollectionView *)collectionView willDisplayCell:(UICollectionViewCell *)cell forItemAtIndexPath:(NSIndexPath *)indexPath{
if ([cell respondsToSelector:@selector(tintColor)]) {
// if (tableView == self.tableView) {
CGFloat cornerRadius = 6.f;
cell.backgroundColor = UIColor.clearColor;
CAShapeLayer *layer = [[CAShapeLayer alloc] init];
CGMutablePathRef pathRef = CGPathCreateMutable();
CGRect bounds = CGRectInset(cell.bounds, 10, 0);
BOOL addLine = NO;
//只设置最后一行圆角(如需要设置整个section为圆角,参考tableview Section 设置)
if (indexPath.row == [collectionView numberOfItemsInSection:indexPath.section]-1 || (indexPath.row == 0 && indexPath.row == [collectionView numberOfItemsInSection:indexPath.section]-1)) {
CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds));
CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds), CGRectGetMidX(bounds), CGRectGetMaxY(bounds), cornerRadius);
CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds));
} else {//其他行为举行
CGPathAddRect(pathRef, nil, bounds);
addLine = YES;
}
layer.path = pathRef;
CFRelease(pathRef);
//颜色修改
layer.fillColor = [UIColor whiteColor].CGColor;
layer.strokeColor=[UIColor clearColor].CGColor;
if (addLine == YES) {
CALayer *lineLayer = [[CALayer alloc] init];
CGFloat lineHeight = (1.f / [UIScreen mainScreen].scale);
lineLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-lineHeight, bounds.size.width-10, lineHeight);
lineLayer.backgroundColor = BackgroundLightGray.CGColor;
[layer addSublayer:lineLayer];
}
UIView *testView = [[UIView alloc] initWithFrame:bounds];
[testView.layer insertSublayer:layer atIndex:0];
testView.backgroundColor = BackGround_COLOR;
cell.backgroundView = testView;
}
}
UIView设置某个圆角:以设置上面两个为圆角例
//设置上面两个为圆角
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect: _contentView.bounds byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii:CGSizeMake(6,6)];
//创建 layer
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = _contentView.bounds;
//赋值
maskLayer.path = maskPath.CGPath;
_contentView.layer.mask = maskLayer;
