How can I get the height of a specific row in my UITableView
提问by aneuryzm
In my UITableViewi've set different heights for different rows using the delegate method: tableView:heightForRowAtIndexPath:
在我中，UITableView我使用委托方法为不同的行设置了不同的高度：tableView:heightForRowAtIndexPath:
Now given a NSIndexPath, I would like to get the height I've previously assigned for a specific row.
现在给出一个NSIndexPath，我想获得我之前为特定行分配的高度。

CGRect frame = [tableView rectForRowAtIndexPath:indexPath];
NSLog(@"row height : %f", frame.size.height);
Using frame.size.heightyou can get height of particular row

-(CGFloat)getHeightAtIndexPath:(NSIndexPath *)indexPath{
if(indexPath.row == 0)
return 20.0;
else if(indexPath.row == 4)
return 40.0;
return 50.0; //Default
}
Call the above function in tableView:heightForRowAtIndexPath:as
调用上面的函数tableView:heightForRowAtIndexPath:作为
return [self getHeightAtIndexPath:indexPath];
And you can use the same function on say button click action of a button inside a specific cell, with having button.tag=indexPath.row
并且您可以在特定单元格内的按钮的说按钮单击操作上使用相同的功能，具有 button.tag=indexPath.row
-(IBAction)btnClick:(id)sender{
UIButton *btn=(UIButton *)sender;
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:btn.tag inSection:0];
CGFloat height=[self getHeightAtIndexPath:indexPath];
}
