我已经阅读了很多类似的问题,但我无法弄清楚为什么视图不起作用..我已经花了四个小时在这上面,所以我认为是时候寻求帮助了。
我的主要 VC 代码是一个 UITableView,在 didSelectRowAtIndexPath 中使用了这个方法:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(@"%s", __FUNCTION__);
svc = [[SubViewController alloc] initWithNibName:@"SubView" bundle:nil];
//UINavigationController *nc = [[UINavigationController alloc] init];
switch (indexPath.section) {
case 0 :
switch (indexPath.row) {
case 0 :
NSLog(@"0");
svc.label.text = @"Item";
break;
case 1:
NSLog(@"1");
svc.label.text = @"Category";
break;
}
break;
NSLog(@"2");
case 1 : svc.title = @"Second Cell"; break;
case 2 : svc.title = @"Third Cell"; break;
case 3 : svc.title = @"Image"; break;
case 4 : svc.title = @"Notes"; break;
NSLog(@"3");
break;
}
NSLog(@"4");
//svc = [[SubViewController alloc] init];
NSLog(@"svc is %@", svc);
UINavigationController *nc = [[UINavigationController alloc] initWithNibName:@"SubView" bundle:nil];
//initWithRootViewController:svc];
[nc pushViewController:svc animated:YES];
NSLog(@"self.navigation is as %@",nc);
NSLog(@"5");
[tableView deselectRowAtIndexPath:indexPath animated:NO];
}
你也可以看到我尝试过的。输出日志显示:
2013-02-12 13:32:22.858 CollapsableTableView[35122:c07] -[ViewController tableView:didSelectRowAtIndexPath:]
2013-02-12 13:32:22.859 CollapsableTableView[35122:c07] -[SubViewController initWithNibName:bundle:]

所以找到了 SubView,但没有加载..任何想法都会受到重视。谢谢
更新。发表评论后(谢谢:))我的代码现在看起来像这样,但仍然没有...
svc = [[SubViewController alloc] initWithNibName:@"SubView" bundle:nil];
UINavigationController *nc = self.navigationController;
switch (indexPath.section) {
case 0 :
switch (indexPath.row) {
case 0 :
NSLog(@"0");
svc.label.text = @"Item";
break;
case 1:
NSLog(@"1");
svc.label.text = @"Category";
break;
}
break;
NSLog(@"2");
case 1 : svc.title = @"Second Cell"; break;
case 2 : svc.title = @"Third Cell"; break;
case 3 : svc.title = @"Image"; break;
case 4 : svc.title = @"Notes"; break;
NSLog(@"3");
break;
}
NSLog(@"4");
//svc = [[SubViewController alloc] init];
NSLog(@"svc is %@", svc);
[nc pushViewController:svc animated:YES];
//pushViewController:svc animated:YES];
NSLog(@"self.navigation is %@",nc);
NSLog(@"5");
