Question

所以我需要你的帮助！我创建了UITableViewController：ContactDetailViewController。在nib文件中的IB中，我在表视图之前添加了一个视图，并将其连接到headerView - .h文件中声明的UIView。我还创建了一个视图：CustomerHeaderView 但是，当我运行下面的代码时，它会在以下行中抛出异常：

headerView = [[UIView alloc] initWithNibName:@"ContactHeaderDetail" bundle:nil];

抛出的错误是：

2010-05-20 10:59:50.405 X[19620:20b] *** -[UIView initWithNibName:bundle:]: unrecognized selector sent to instance 0x3ca4fa0
2010-05-20 10:59:50.406 X[19620:20b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView initWithNibName:bundle:]: unrecognized selector sent to instance 0x3ca4fa0

所以任何人的想法？

非常感谢，菲奥娜

Answer 1

headerView = [[UIView alloc] initWithNibName:@"ContactHeaderDetail" bundle:nil];

UIView没有XIB或initWithNibName函数。

您的意思是制作UIViewController吗？

UITableViewController和viewForHeaderInSection问题
