从customcell转到viewController [英] Going to viewController from customcell

问题描述

我有一个加载自定义单元格的表格视图.自定义单元格上有一个按钮，单击此按钮将打开一个pickerview，其中有多个选项可供选择.

i am having a tableview in which custom cells are loaded.Custom cell has a button on click of which a pickerview will open which will have options to choose from.

问题是modalViewController方法无法正常工作，它给出了以下错误.

The problem is that modalViewController method is not working, it is giving the following error.

Selector *sel = [[Selector alloc]initWithNibName:@"Selector" bundle:nil];
[self PresentModalViewController:sel animated:YES];
error:property presentModalViewController not found on object of type CustomCell *...and selector is the pickerview controller class...the method is written in ibaction function in customcell.m file   

v如何从自定义单元格调用其他视图?

How can v call other view from custom cell?

谢谢

推荐答案

首先，将您的类命名为选择器"是一个令人困惑的主意.您应该使用更具描述性的内容，而不是obj-c关键字.

First, naming your class "Selector" is a horribly confusing idea. You should use something more descriptive, and something that is not already an obj-c keyword.

对于您的问题，我认为您应该使用委托从单元格视图中获取对控制器的引用.在您的自定义单元格视图类中，执行以下操作:

As for your problem, I think you should use a delegate to get a reference from your cell view to the controller. In your custom cell view class, do something like:

@property (nonatomic, assign) id delegate;

// implementation
@synthesize delegate = _delegate;

// in your cell... method
[self.delegate presentPicker];

在这里，委托ivar将指向您的视图控制器.要进行设置，请找到分配单元的位置，然后执行

Here, the delegate ivar would point back to your view controller. To set that up, find the place where you alloc your cell, and do

ACell *aCell = [ACell alloc] init];
aCell.delegate = self;
