所有单元格子视图都位于哪个子视图？ （在自定义单元格类中）

Question

I have a custom UITableViewCell with a class linked to it.

In awakeFromNib , (of the custom cell class,) I made a for in loop:

for (id view in self.subview)
{
    if (view isKindOfClass:[UITextField class]) {
        UITextField *textField = (UITextField *)view;
        [textField setBackgroundColor:[UIColor redColor]];
    }
}

When I run it on the simulator, no textFields background color changes.

I'm pretty sure, that what I have wrong is: self.subview . What should I put in place of that?

Answer 1

Give a tag to your view in the cell that contain textfield let suppose tag = 0

for (UIView *view in [self viewWithTag:0].subviews)
{
    if ([view isKindOfClass:[UITextField class]]) {
        UITextField *textField = (UITextField *)view;
        [textField setBackgroundColor:[UIColor redColor]];
    }
}

Hope this help.

Get subviews from self.contentView -

Try the following code

for (id view in self.contentView.subviews) {
    if ([view isKindOfClass:[UITextField class]]) {
        UITextField *textField = (UITextField *)view;
        [textField setBackgroundColor:[UIColor redColor]];
    }
}
