Get selected button value from the UIButton - ios

Question

From the array I am creating button with the array values inside each button, Here I want to place a radio button before each button. while clicking the radio button i want to get it selected or not. In the below code I can display the button and the radio button image but cannot get the selected button value. How can i get the radio button selected or not for each button
//My Array
labelArrays = [NSMutableArray arrayWithObjects:#"one", #"two", #"three",#"four",#"five",#"six", nil];
//Creating button with placing a radio button image inside
-(void) createbutton:(CGRect) frame {
CGFloat xCoordinate = frame.origin.x;
CGFloat yCoordinate = frame.origin.y;
CGFloat buttonHeight = frame.size.height;
CGFloat buttonWidth = frame.size.width;
CGFloat gapBetweenTwoButton = 2;
for(int counter = 0; counter < [labelArrays count]; counter++) {
button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button =[UIColor clearcolor];
[button setFrame:CGRectMake(xCoordinate,yCoordinate, 100, 40)];
NSString* titre = [labelArrays objectAtIndex:counter];
[button setImage:[UIImage imageNamed:#"radio_selected.png"] forState:UIControlStateNormal];
button.titleEdgeInsets = UIEdgeInsetsMake(0,10,0,0);
[button setTitle:[NSString stringWithFormat:#"%#",titre] forState:UIControlStateNormal];
[button setUserInteractionEnabled:YES];
[self. button addTarget: self action: #selector(buttonAction:)forControlEvents: UIControlEventTouchUpInside];
[self addSubview: button];
if((counter+1)%3 == 0) {
xCoordinate = 0;
yCoordinate = yCoordinate + buttonHeight + gapBetweenTwobutton;
xCoordinate = xCoordinate + buttonWidth + gapBetweenTwoLabels;
}
}
//my frame
[self createbutton:CGRectMake(32,20,220,40)];

It's very simple to get selected button value by using its tag value. See here and try below code.
Put these line in viewDidLoad()
labelArrays = [NSMutableArray arrayWithObjects:#"one", #"two", #"three", #"four", #"five", #"six", nil];
[self createButtons];
And then define these methods.
- (void)createButtons
{
int x = 30, y = 20;
for (int i = 0; i<labelArrays.count; i++)
{
UIButton *btnImage = [UIButton buttonWithType:UIButtonTypeCustom];
btnImage.frame = CGRectMake(x, y, 100, 40);
btnImage.backgroundColor = [UIColor redColor];
btnImage.tag = 700+i;
[btnImage setImage:[UIImage imageNamed:#"radio_unselect.png"] forState:UIControlStateNormal];
btnImage.titleEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
[btnImage setTitle:[NSString stringWithFormat:#"%#", [labelArrays objectAtIndex:i]] forState:UIControlStateNormal];
[btnImage addTarget: self action: #selector(changeValue:)forControlEvents: UIControlEventTouchUpInside];
[self.view addSubview:btnImage];
if ((i+1)%2 == 0)
{
x = 30;
y = y+btnImage.frame.size.height+10;
}
else
{
x = x+btnImage.frame.size.width+30;
}
}
}
- (IBAction)changeValue:(UIButton *)sender
{
UIButton *btn = (UIButton *)[self.view viewWithTag:sender.tag];
if (btn.selected == TRUE)
{
[btn setImage:[UIImage imageNamed:#"radio_unselect.png"] forState:UIControlStateNormal];
btn.selected = FALSE;
}
else
{
[btn setImage:[UIImage imageNamed:#"radio_select.png"] forState:UIControlStateNormal];
btn.selected = TRUE;
NSLog(#"%#", btn.titleLabel.text);
}
}
