【问题描述】:
我正在 iOS7 中开发应用程序。我有一个TableViewController,它的风格是分组的。
我成功实现了this 解决方案,可以随心所欲地获得TableView 的曲线。
编辑:- 我没有为单元格使用任何自定义类。我刚刚从笔尖添加了TableView,默认情况下也使用单元格。
实现的代码如下:-
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([cell respondsToSelector:@selector(tintColor)]) {
if (tableView == self.tblviwSample) {
CGFloat cornerRadius = 5.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);
layer.fillColor = [UIColor colorWithWhite:1.f alpha:0.8f].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;
}
}
}
此代码的效果 - See this - before selection
但是遇到一个问题,当我选择一个单元格时,它看起来很奇怪,就像this
我希望该部分以适当的方式。任何想法将不胜感激。
【问题讨论】:
-
我今天也偶然发现了这个问题。我刚刚将单元格的
selectionStyle更改为UITableViewCellSelectionStyleNone,直到找到可靠的解决方案。单元格收到了选择,但没有突出显示它。
