多个单元格选择在tableview中 [英] Multiple cell selection In tableview

问题描述

我想将照片上传到twitter，facebook和twit pic等等。我在Array中使用了它并在Table视图中显示。我正在使用shareKit。我编码好像我选择了一个单元格（对于eg.Twitter）然后它会将照片上传到twitter我想要选择多个单元格并在一个按钮上执行此发送操作（发送到选定的行项目）。我能够标记/取消标记单元格但是如何获取单元格的选定值。我不希望它处于表的编辑模式..

I want to upload photos to twitter , facebook and twit pic and many more. I took this in Array and displayed in Table view. I am using shareKit . I coded like if I select one cell (for eg.Twitter) then It will upload photo to twitter I want to select more than one cell and perform this sending action on one button(send to selected row item). I am able to mark/unmark cells but how to get selected value of cell. I dont want it to be in table's editing mode..

代码：

-  (void) tableView:(UITableView *)atableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }


    else {

        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }



}

推荐答案

让 sourceArray 成为用于填充tableview的数组。
和 selectedObjects 是一个被选中的对象数组，初始化为包含0个对象。它应该是（私有）类实例变量。

Let sourceArray be your array which you use to populate the tableview. And selectedObjects be an array of objects that are selected, initialized to contain 0 objects. It should be a (private) class instance variable.

// NSMutableArray * selectedObjects = [[NSMutableArray array] retain];

-  (void) tableView:(UITableView *)atableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    YouObjectType *object = [sourceArray objectAtIndex:indexPath.row]; //This assumes that your table has only one section and all cells are populated directly into that section from sourceArray.
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
        [selectedObjects removeObject:object];
    }
    else {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        [selectedObjects addObject:object];
    }
}

然后在你描述的按钮的发送动作方法中，使用 selectedObjects 数组中的对象来执行所需的操作。

Then in the sending action method of the button you described, use the objects in the selectedObjects array to do the required operation.
