如何在drawRect方法中将UIView添加到自定义UITableViewCell

Question

In my project need to add uiview in UITableViewCell. I can add UIView using following code in UITableViewCell class.

    -(void)drawRect{
       [cell.contentView addSubview:myView];
    } 

Is this a efficient way to show when large amount of table cell are displaying. Is there other way to add UIView using method like.

    drawInRect

Answer 1

您将需要在- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath ，它是UITableViewDataSource协议的一部分。

Answer 2

Don't use drawRect method that way. That method is using for drawing some parts of the ui-element and may call several times per a sec. You should add a subview in cellForRowAtIndexPath method ( UITableViewDataSource protocol) or in - (void)awakeFromNib . Don't forget to remove that subview in - (void)prepareForReuse method of your UITableViewCell subclass.
