捏合时单元格的 IndexPath？
我发现当 tableview 被 cellForRowAtIndexPath 声明的 UIPinchGestureRecognizer 挤压时。现在想要找到被挤压的特定单元格的索引路径。所以我写了这样的...
- (void)pinchDetected:(UIPinchGestureRecognizer*)gestureRecognizer {
CGPoint p = [gestureRecognizer locationInView:tblAccountsList];
NSIndexPath *indexPath = [tblAccountsList indexPathForRowAtPoint:p];
NSLog(@"indexPath.row = %@", indexPath.row);
UITableViewCell *pinchedCell = [tblAccountsList cellForRowAtIndexPath:indexPath];
NSLog(@"pinchedCell = %@", pinchedCell);
}
问题出在indexPath.row和单元格中，两种情况下得到的值都是空的。
所以，请有人帮我找到被挤压的索引路径或行。
I am finding when tableview is pinched with UIPinchGestureRecognizer declaring at cellForRowAtIndexPath. Now want to find indexPath of a particular cell that was pinched. so i wrote the like this...
- (void)pinchDetected:(UIPinchGestureRecognizer*)gestureRecognizer {
CGPoint p = [gestureRecognizer locationInView:tblAccountsList];
NSIndexPath *indexPath = [tblAccountsList indexPathForRowAtPoint:p];
NSLog(@"indexPath.row = %@", indexPath.row);
UITableViewCell *pinchedCell = [tblAccountsList cellForRowAtIndexPath:indexPath];
NSLog(@"pinchedCell = %@", pinchedCell);
}
Problem is in indexPath.row and cell both cases value am getting is null.
So, plz can someone help me to find the indexPath or row that was pinched.

在 row 方法的单元格中，设置 cell.tag = indexpath.row 并
在 - (void)pinchDetected:(UIPinchGestureRecognizer*)gestureRecognizer 中
从 cell.tag 再次使用 UITableViewCell* cell = (UITableViewCell*)recognizer.view 可以获取行索引。
in cell for row method, set cell.tag = indexpath.row and
in - (void)pinchDetected:(UIPinchGestureRecognizer*)gestureRecognizer
use UITableViewCell* cell = (UITableViewCell*)recognizer.view again from cell.tag you can get the row index.
