如果想在ios7的UITableView实现ios6中的圆角效果，可以用如下的办法：
1.重写UITableView的一个方法，如下：

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath
*)indexPath{ if
([cell respondsToSelector:@selector(tintColor)]) { if
(tableView == self.tableView) { 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

{ 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; } }} |

2.在storyboard里面设置UITableView的样式，如下图：
具体情况可以按各自的需要来。
不过更多适配ios6的时候还是按照各自的模式来的，需要让美工准备两套图片，一份ios6的，一份ios7的。
