Question

I know xcode don’t have radio Button

so I try to add a custom button and make it action like a radio button

This is the image I use

and this is the code I set to cell

UIButton *but = [UIButton buttonWithType:UIButtonTypeCustom];
[but setImage:[UIImage imageNamed:@"radio-off.png"] forState:UIControlStateNormal];
[but setImage:[UIImage imageNamed:@"radio-on.png"] forState:UIControlStateSelected];
[but setFrame:CGRectMake(0, 0, 44, 44)];
[but addTarget:self action:@selector(radioButton:) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView= but;

and this is the problem I want to ask is

how can I give a void in - (IBAction)radioButton:(UIButton *)button

To control Two Radio Button in Two Rows

If Row 1 Radio button’s selected is YES

btn in row 2 will be btn.state=NO and won’t response the

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

It will be like this pic

How to set the if conditions in - (IBAction)radioButton:(UIButton *)button

this pic is fake…I only add the button in the cell…and changed the text color

Great Thanks to all stack overflow friends~

You will need an array of all the radio buttons. Remember that table cells get recycled/may not be visible, etc. so create an array just with the buttons and then grab the right button out of that array in your tableView:cellForIndexPath: method.

So in your tableView:cellForIndexPath: method you would do something like this:

cell.accessoryView = [myButtonArray objectAtIndex:[indexPath row]];

Then, in your radioButton: radioButtonPressed: method you would do:

// Select the pressed button.
[button setSelected:YES];
// Unselect all others.
for (UIButton *other in myButtonArray) {
    if (other != button) {
       [other setSelected:NO];
    }
}
