Ios7 自定义单元格代替UIlabel怎么办？,ios7,Ios7,自定义单元格代替UIlabel我能做什么？在方法中，我希望使用自定义单元格，而不是标签。我想要自定义单元格，并且我是ios中的新成员或新成员，因此我不知道自定义单元格的更多细节，因此请告诉我如何在我的代码中使用自定义单元格代替tableview中的标签 //AppDelegate.h #import <UIKit/UIKit.h> @class ViewController; @interface AppDelegate : UIResponder <UIA

自定义单元格代替UIlabel我能做什么？在方法中，我希望使用自定义单元格，而不是标签。我想要自定义单元格，并且我是ios中的新成员或新成员，因此我不知道自定义单元格的更多细节，因此请告诉我如何在我的代码中使用自定义单元格代替tableview中的标签

请查看我上面的代码，只需告诉我有关自定义单元格的信息。

在您的
cellforrowatinexpath
的表视图方法中。您需要用自定义的
uitableviewcell
类替换此代码。然后在这个文件中，您需要创建nib文件并在
cellforrowatinexpath
方法中加载

//注释此代码

 //   UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
//用下面提到的链接代码修改相同的上述代码

请参阅您说的“…自定义单元格代替UIlabel我能做什么？”

根本不清楚你在问什么。表视图单元格仅位于表视图内部，并且表视图不能包含UILabel来代替表视图单元格。它们永远不能互换

你发布了很多代码，大部分都是标准的锅炉铭牌代码。我费力地完成了这一切（真烦人…）

在cellForRowAtIndexPath方法中，您正在创建一个标准UITableViewCell并向其添加5个UILabel。在我看来，标签太大，无法放入单元格，但这是次要的

您想做什么，创建UITableViewCell的自定义子类，其中包含作为IBOutlet的标签，并实例化自定义单元格而不是标准单元格

请清楚地说明你想做什么

此外，您还需要告诉我们您是否正在使用故事板或XIB文件，以及您是否正在使用UITableViewController或标准视图控制器
