Scroll View content size in Universal app?

Question

I am not sure how to set different scroller size dimensions for a universal app.

I have the code below so far in the implementation file for iPhone dimensions, but not sure how to code for iPad scroller dimensions as well.

- (void)viewDidLoad {
    [self.navigationController setNavigationBarHidden:NO animated:NO];
    [super viewDidLoad];

[ScrollerInstructions setScrollEnabled:YES];
[ScrollerInstructions setContentSize:CGSizeMake(300, 2000)];

}

Thank you!

use this, so you can set the contenSize in dependency of the device:

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
    // iPad contentSize
    [ScrollerInstructions setContentSize:CGSizeMake(600, 3000)];
} else if ([[UIScreen mainScreen] bounds].size.height >= 568) {
    // iPhone 5/5s contenSize
    [ScrollerInstructions setContentSize:CGSizeMake(300, 2500)];
} else {
    // old iPhone contenSize
    [ScrollerInstructions setContentSize:CGSizeMake(300, 2000)];
}

a good way to use is, to set this as define in your .pch file like this:

#define IS_IPAD ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
#define IS_IPHONE5 (!IS_IPAD && ([[UIScreen mainScreen] bounds].size.height >= 568))

this way you can use in your source simply:

if (IS_PAD) {

} else if (IS_IPHONE5) {

}
