将UITableViewCell中的子视图中的对象的CGRect转换为UITable中的对于self.view的CGRect [英] Converting a CGRect of a object in a subview in UITableViewCell in UITable to CGRect with respect to self.view

问题描述

我想将UITableViewCell中的子视图中的对象的CGRectaRect转换为UITable中相对于self.view的CGRect。

问题是， aRect是相对于表格单元格中的子视图。
但是我想让它与self.view相关

我试过的是这个
rect = [self.view convertRect：aRect.frame toView：cellView];

解决方案

由于 convertRect：toView：实际上处理接收者坐标中的 CGRect 系统，也许 [cellView convertRect：theFrame toView：self.view] （即调换两个视图在你的通话）将按照你的意图。 >

I want to converte a CGRect "aRect" of a object in a subview in UITableViewCell in UITable to CGRect with respect to self.view.

The problem is that aRect is with respect to the subview in the table cell. But i want to make it so that it is with respect to self.view

What i tried is this rect = [self.view convertRect:aRect.frame toView:cellView]; but it doesn't work.

So how to convert it?

解决方案

Since convertRect:toView: actually deals with a CGRect in the receiver’s coordinate system, maybe [cellView convertRect:theFrame toView:self.view] (i.e. swapping the two views in your call) will work as you intended.
