表格单元子视图迭代未找到TextField [英] Table Cell SubView Iteration Not Finding TextField
问题描述
我创建了一个表,其中每个单元格都包含文本标签和文本字段。我正在添加文本字段 [cell addSubview:passwordField];
,从视觉角度看,它们出现并可编辑等等。
I've created a table where each cell holds both a text label and a text field. I'm adding the textfields as such [cell addSubview:passwordField];
and from a visual perspective they appear and are editable, etc....
当我尝试从文本字段中检索输入的值时,会出现问题。我遍历单元格并尝试抓取子视图(IE文本字段),但是,我的迭代只发现文本标签。
The problem arises when I attempt to retrieve the entered values from the textfields. I iterate over the cells and try to grab the subview (IE the textfield), however, my iteration only discovers the text label.
这是我正在使用的代码搜索:
Here is the code I'm using to search:
for(NSInteger i =0; i < [tableView numberOfRowsInSection:0]; i++){
NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:0];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
UIView* subView = [[cell.contentView subviews]lastObject]; // I've also tried object at index here
// Anything beyond this is just matching....
我采取的另一种方法是递归搜索子视图,但是,再次没有产生任何结果。
Another approach I took was recursively searching the subviews, but, again that yielded no results.
推荐答案
您已在单元格的子视图中添加了 textField
。
You have added your textField
on subView of cell.
[cell addSubview:passwordField];
当您尝试在 cell.contentView $上找到它时c $ c>。
添加 textField
作为的子视图.cell.Contentview
[cell.contentView addSubview:passwordField];
以这种方式找到它 -
And find it in this way -
for(UIView *view in [cell.contentView subviews])
{
if([view isKindOfClass:[UITextfield class]])
{
UITextField *textField = (UITextField *)view;
NSLog(@"%@",textField.text);
}
}
