无法显示表格详细信息
我发誓我已经看了六个教程，但我不知道我做错了什么。我有一个通过 IB 嵌套在 UIView 中的表视图，并且该表的格式和填充都正确。我只是无法让它向我显示详细信息屏幕。表识别出点击，并且该行被选中，但是...该行保持选中状态。然后，绝对什么也不会发生。我可以选择具有相同结果的其他行，但除此之外什么都不会发生。我可以进出视图，并在整个应用程序中拥有完整的功能。我什至可以滚动表格视图，但我永远无法进入单元格详细信息屏幕。我已经在 IB 中将所有必要的部分链接在一起。
这是我的详细视图代码：
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Get the selected cell detail
NSString *theString = [secondview objectAtIndex:indexPath.row];
celldetails *dvController = [[celldetails alloc] initWithNibName:@"celldetails" bundle:nil];
dvController.cellString = theString;
[self.navigationController pushViewController:dvController animated:YES];
}
我尝试过“bundle:nil”和“bundle:[NSBundle mainBundle]”，但都没有产生所需的结果。有人有什么建议吗？
I swear I've looked at a half-dozen tutorials and I can't figure out what I'm doing incorrectly. I have a tableview nested within a UIView via IB, and the table both is formatted and populates correctly. I just can't get it to show me the details screen. The table recognizes the tap, and the row is selected, but... the row stays selected. Then, absolutely nothing happens. I can selected other rows with the same results, but nothing ever happens past that. I can move in and out of the view, and have full functionality throughout the entire app. I can even scroll the tableview, but I can never get into the cell detail screen. I've linked all the necessary pieces together in IB.
This is my code for the detail view:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//Get the selected cell detail
NSString *theString = [secondview objectAtIndex:indexPath.row];
celldetails *dvController = [[celldetails alloc] initWithNibName:@"celldetails" bundle:nil];
dvController.cellString = theString;
[self.navigationController pushViewController:dvController animated:YES];
}
I've tried both "bundle:nil" and "bundle:[NSBundle mainBundle]", but neither produces the desired result. Anyone have a word of advice?

如果
pushViewController:animated:不做任何事情，你的navigationController可能是nil，但除此之外它肯定应该工作，因为UIViewController发送到实例将显示某种视觉变化（除非视图相同并且您不使用动画）。尝试将pushViewController:animated:的NSLog(@"blah");行添加到您的didSelectRowAtIndexPath:实现中，以确保它被调用。或者在该方法中设置断点。一堆
nil就可以了。如果未找到.xib，那么您将收到相应的调试消息，因此它正在查找.xib。.xib甚至还设置了有效的view插座，因为如果您加载.xib但没有view，应用程序就会崩溃> 插座已设置。If
pushViewController:animated:doesn't do anything, yournavigationControllercould benil, but otherwise it should definitely work since aUIViewControllerinstance sent topushViewController:animated:will show some sort of visual change (unless the views are identical and you don't use animation). Try adding anNSLog(@"blah");line to yourdidSelectRowAtIndexPath:implementation, just to be sure it's getting called. Or stick a breakpoint in that method.A bundle of
nilis fine. If the.xibwas not found, then you'd get debug messages to that effect, so it's finding a.xib. The.xibeven has a validviewoutlet set since the app crashes if you load a.xibbut noviewoutlet is set.
