        int i=0;
        float x=5,y=13;
        //add array elements as button title
        for (i=0; i< [_englishArray count]; i++) {
            button.tag=i+1;
            button = [UIButton buttonWithType:UIButtonTypeCustom];
            [button addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
            [button setTitle:[_englishArray objectAtIndex:i] forState:UIControlStateNormal];
            button.frame= CGRectMake(x, y, 29, 30);
            button.titleLabel.textColor =[UIColor whiteColor];
            x= x+31;
            if (x==320 || x>310) {

    [button addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside];

    button.frame= CGRectMake(x, y, 29, 30);
    [button setBackgroundColor:[UIColor grayColor]];
    [button setTitle:[_englishArray objectAtIndex:i] forState:UIControlStateNormal];
    //button.titleLabel.textColor =[UIColor whiteColor];
    [_keyboardImageView addSubview:button];
    x= x+31;

Make sure you define your button in for loop like

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

and than specify tag.

   button.tag=i+1;

You have to define button in for loop instead of .h file.

And for get title text

      for (int j=0;j<=[_englishArray count]; j++) {
  UIButton  *butt = (UIButton *)[_keyboardImageView viewWithTag:j+1];
    NSLog(@"%@",butt.titleLabel.text);
}

hope it will help you.

Since you set the title with setTitle:forState:, use titleForState: to get the title:

NSLog(@"title is %@", [butt titleForState:UIControlStateNormal]);

Of course this assumes that butt isn't nil. You need to assign the button's tag after you allocate the button:

button = [UIButton buttonWithType:UIButtonTypeCustom];
button.tag=i+1;
