如何从按钮按下事件中获取单元格数据（自定义表格视图单元格）

Question

There is a button and label on my custom tableview cell. This is how Im set the button action.

[cell.btnPlus addTarget: self action: @selector(plusButtonPressed) forControlEvents: UIControlEventTouchUpInside];

This method is working fine. I want to get the label text of the cell which the button is pressed.

How could I do it?

Answer 1

将属性添加到指向单元格的按钮，或者，如果btnPlus是单元格的子视图，请使用btnPlus.superview.textlabel.text 。

Answer 2

将标签设置为该按钮并进行标签，然后可以使用带有标签选项的视图获取标签文本

Answer 3

change @selector(plusButtonPressed) to @selector(plusButtonPressed:) (note the added colon at the end)

then in your

- (void)plusButtonPressed:(UIButton*)sender {
    NSString *theText = sender.superview.textlabel.text;
}

(this is assuming the plus button is added to the contentView of the UITableViewCell)

Answer 4

set tag to cell:

cell.contentView.tag = indexPath.row+10000*indexPath.section; //or any you like
[cell.contentView addSubview:button];

then, in button's callback:

int raw=0;
int section=0;
long tag = [sender superview].tag;
NSLog(@"tag: %ld", tag);
for (int i = 0; i<[data count]; i++) {
    if (tag>=10000) 
    {
        tag-=10000;
        section++;
    }
    else i = [data count];
}
raw = tag;

now, you have full access to your cell. use calculated raw and section ta get access to cell.
