Question

I am doing an application on a Multiple Choice Question (MCQ) where I have to get questions, answers from a webservice. I have 1 question with 4 options, among the 4 options, I have 1 correct answer. Each of the options, I created a button programmatically. This is how I did it:

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(40, yButton, 30, 30);
    [button setTitle:@" " forState:UIControlStateNormal];

[button addTarget:self action:@selector(correctPressed)
 forControlEvents:UIControlEventTouchDown];
   [buttonArray addObject:button];

How many options I have in a questions will determine how many buttons will be created. Now when I want to show an indication that when a certain button is clicked, that button needs to stay highlighted until I decides to change my answer. I have done a few approaches.

I used IndexPath, hoping I could use indexPath.row like in TableView. It didnt work out at all. Can anyone help?

Thanks

Answer 1

for(int i=0; i<[videolistArray count];i++){


    NSArray *myWords = [[[videolistArray objectAtIndex:i] valueForKey:@"video"] componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"/"]];
    //NSLog(@"%@",[myWords lastObject]);

    UIButton *guitaristButton = [[UIButton alloc]init];
    guitaristButton.frame = CGRectMake(0, ycomp, 300, 35);
    guitaristButton.tag = i;
    [guitaristButton setBackgroundImage:[UIImage imageNamed:@"green-buttons.png"] forState:UIControlStateNormal];
    [guitaristButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [guitaristButton setTitle:[myWords lastObject] forState:UIControlStateNormal];
    [guitaristButton addTarget:self action:@selector(VideoButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
    //[guitaristButton performSelector:<#(SEL)aSelector#> withObject:<#(id)object1#> withObject:<#(id)object2#>
    [videoScrollView addSubview:guitaristButton];
    [guitaristButton release];

    ycomp = ycomp+35;   
}
videoScrollView.contentSize=CGSizeMake(300, ycomp);

}
-(void)VideoButtonSelected:(UIButton*)sender{
NSArray *myWords = [[[videolistArray objectAtIndex:sender.tag] valueForKey:@”video”] componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@”/”]];
//NSLog(@”%@”,[myWords lastObject]);
[setAlarmVedioButton setTitle:[myWords lastObject] forState:UIControlStateNormal];
[videoNameButtonView removeFromSuperview];
vedioString=[[videolistArray objectAtIndex:sender.tag] valueForKey:@”video”] ;
}

in above code me make uibutton with help of array count and when i select any button then it display the same text value of array on last button
