根据服务器的响应动态创建UIButton

Question

I need to implement a view that require me to create a buttons based on the response from the server.

Example response:

{
   ...
    "enable_button_1" = 1;
    "enable_button_2" = 1;
    "enable_button_3" = 1;
   ...
}

Currently, I try to create the buttons manually using Interface Builder. And each of them are embedded in UIView and put on top of each other. Like so: They are hidden by default. So, whenever on or more buttons enabled, I will check using if conditions and then unhide the view.

eg. only one button enabled

eg. two button enabled

But the thing is by doing so, I would probably miss a few use case and this seems like a bad practices. Is there any way that I could create it dynamically instead of creating multiple buttons in UIViews in Interface Builder?

You can always create buttons programatically and add them to your view. You'd have to calculate the width of the button-frame so that they always fit the view 100%.

For example somehow like this:

    //Here you'd have to calculate the correct position of the button you want to add
    CGRect frame = CGRectMake(0, 0, self.buttonView.frame.size.width, self.buttonView.frame.size.height);
    UIButton *button = [[UIButton alloc] initWithFrame:frame];
    [button setTitle:@"myButton" forState:UIControlStateNormal];
    [self.buttonView addSubview:button];
