IO获取UITableView的cell内容

UITableView 获取cell的内容

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textChanged:)name:UITextViewTextDidChangeNotification object:nil];

#pragma mark 监听方法
- (void)textChanged:(NSNotification *)notification
{
    if ([notification.object isKindOfClass:[UITextView class]]) {
        UITextView * textview = notification.object;
        if (textview) {
            NSLog(@"notification-UITextView->%@",textview.text);
            //获取改变了的textfield对应的NSIndexPath
            //获取到对应的NSIndexPath就可以设置对应的数据源了
            CGPoint point = [textview.superview convertPoint:textview.frame.origin toView:self.tableView];
            NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:point];
        }
    }

}

有个更好的替代方法

    [cell.delBtn addTarget:self action:@selector(delEhr:event:)
       forControlEvents:UIControlEventTouchUpInside];

-(void)delEhr:(UIButton*)sender event:(id)event{
    NSSet *touches =[event allTouches];
    UITouch *touch =[touches anyObject];
    CGPoint currentTouchPosition = [touch locationInView:self.tableView];
    NSIndexPath *indexPath= [self.tableView indexPathForRowAtPoint:currentTouchPosition];
    if (indexPath!= nil)
    {
        NSLog(@"select %d",indexPath.row);
    }
}
