在它们之间一定距离处创建UIbutton

Question

I made an app which has got API support for developers. Developer who want to make a plugin for my app just have to call a method " -(void)createToggle " and an UIButton will be automatically added to my application's view. The problem is that I don't know how to implement in " -(void)createToggle " a way to make UIButtons with a certain distance (180 in this case) between them.

I made a loop to do that, here you can see the code:

-(void)createToggle 
{
    for (unsigned int i=0; i<[[SPUtils dylibs] count]; i++) 
    {

        toggle = [UIButton buttonWithType:UIButtonTypeCustom];
        toggle.frame = CGRectMake(3487+180 *i, 27, 100, 100); 
        [toggle addTarget:self action:@selector(buttonTarget:) forControlEvents:UIControlEventTouchUpInside];
        [toggleScroll addSubview:toggle];

    }
}

You could paste the snippet here. The problem seems to be on line:

toggle.frame = CGRectMake(3487+180 *i, 27, 100, 100);

3487 is a big number. Where the buttons are going to be placed? iPhone has a horizontal range of 0->320 for x. Try this instead:

float margin=180;
float buttonWidth=100;
toggle.frame = CGRectMake(margin+i*buttonWidth+i*margin, 27, 100, 100);

Let me know if it's solved.
