objective-c - UITableView 中的圆顶角

Question

我确实在 UItableView 中添加了圆角，但只在顶角。问题是当我在 UItableView 中使用掩码时，UItableView 只显示前 4 个单元格。

当我从掩码注释代码时，表格视图工作正常..

这是我的代码：

UIBezierPath *maskPath;
maskPath = [UIBezierPath bezierPathWithRoundedRect:_tbFeeds.bounds byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight) cornerRadii:CGSizeMake(9.0, 9.0)];

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = _tbFeeds.bounds;
maskLayer.path = maskPath.CGPath;
_tbFeeds.layer.mask = maskLayer; //tbfeeds is my tableview
[maskLayer release];

Answer 1

一种方法是向 tableview 添加标题：

- (void)loadView {
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 10)]; // height of header (10)
    [headerView setBackgroundColor:[UIColor whiteColor]]; // color of header (white)

    UIBezierPath *maskPath;
    maskPath = [UIBezierPath bezierPathWithRoundedRect:headerView.bounds byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight) cornerRadii:CGSizeMake(5.0, 5.0)];

    CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
    maskLayer.frame = headerView.bounds;
    maskLayer.path = maskPath.CGPath;
    headerView.layer.mask = maskLayer;

    self.tableView.tableHeaderView = headerView;
}
