Iphone将tableview与nib文件按行分组，我的行在每个部分重新启动，它不会显示下一部分行

我从SDK开始，尝试使用tableview设置一个应用程序来显示信息

我创建了一个基于窗口的应用程序，我使用了一个带有tableview的选项卡栏，该选项卡栏中有一个导航栏，可以来回移动，它“显然”工作得很好，但我遇到了一个问题，每当你点击每个（1,2,3…）节的第一行时，它就会不断调用第一节的第一行，我做了很多研究：教程、书籍、论坛，但似乎找不到办法让它发挥作用。我发现了很多有用的信息，虽然这对我帮助很大，但并不能解决我的问题。我已经适应它好几天了

因此，在尝试了我能找到的所有资源后，我向你呼救

这是我试图使用的代码，我想它会对你们中的一些人有所帮助

//我正在用这个 MyTableViewController.h{

#import <UIKit/UIKit.h>
#import "firstCustomCell.h"

是的，我总是有这个问题-我不确定它是什么，但我认为这与以下事实有关：

==0

也是

==NO

或

==false

，但我不确定

通常对我有效的方法是将其视为整数，因此：

if([indexPath section] < 1){
  // section 0
}
else if([indexPath section] > 0 && [indexPath section] < 2){
  // section 1
}
else{
  // etc...
}

然后进行字符串比较：

if([section isEqualToString:@"0"]){
  // first section
}
else if([section isEqualToString:@"1"]){
  // next section
}
else {
  // etc...
}

在

-（void）tableView:（UITableView*）tableView didSelectRowAtIndexPath:（nsindepath*）indepath

中，您只是忽略了indepath.section。没有考虑该节的调用

---

您的分区标题是否有效？对我来说，这看起来没问题。
添加一个

return nil；

添加此方法的结尾以消除此警告。之所以会出现此警告，是因为如果节大于2，则不会返回任何内容

嗯，你真的在10周内创建了10个不同的类和10个不同的nib文件吗？我怀疑这是否真的有必要。如果你的客户希望在下一个版本中获得52周的支持，这将使你陷入大量的复制和粘贴；-）

对不起，你到底是在实现这些方法吗？？？感觉很好，但是…哦，对不起-在您看到的任何表视图方法中，

something…forrowatinexpath:（nsindepath*）indexPath

您可以使用此代码。我正在我的手机中尝试切换时的rowatindexpath，但没有成功。不要担心感觉noob-：p我们都在那里过一次，说实话，很难理解和理解。你说问题是当你点击一行时？输入didselectrowatindexpath实际上是12几个星期，但我需要他们在里面加载另一个tableview，以显示更多数据，并分别转到其他4或5个视图（lol）。如果你能告诉我一个不同的方式，我将不胜感激。是的，我明白你的意思，这将是一项繁重的工作，因此如果你现在有更好的方式，请分享…..谢谢。是的，我的标题有效，但感谢你，我不再收到警告。你是对的，我没有返回任何内容，现在我返回零；警告消失。我会的我很想给你们两个理由，因为你们两个都帮我解决了这件事，我确实把两个答案放在了一起，现在它真的起作用了。到达那里让我很震惊，但祈祷和听从你们的建议最终做到了。FluchPunkt你帮我意识到我没有在我的didSelectRowAtIndexPath m中调用这些部分ethod，并帮助我摆脱标题警告，我非常感谢你所拥有的这些人。但正是Thomas Clayson记得我如何实现该方法，（还有我的朋友Bucky，来自Youtube，他是objective C training。还有许多其他人。感谢大家。）所以我决定给你们两个最好的答案，但由于我无法做到这一点，我把它交给了托马斯·克莱森。但你们都是对的，我感谢你们的时间和关心。我明天再发。
