If you have children with iPhones, iPod touches, or iPads, or who frequently use yours, and you want to control the type of content they can access when browsing the web in Safari, you're in luck - iOS 7 lets you do just that. Whether you want to try an automatically limit all adult content to prevent a child from accidentally hitting a link they shouldn't, blacklist specific websites, or shut off all sites except for the ones you specifically whitelist, you'll find everything you need right in Settings and Restrictions. Here's how to set up your parental controls!
If you're not overly worried and just want to try and prevent your kids from hitting links that take them to adult material, or there are only a few sites you want to make sure they never land on, you can use the automatic settings, and the blacklist feature.
Repeat this process for each site you'd like to block access to. Keep in mind that if certain websites have mobile sites, you may need to block them separately. For instance, to block CrackBerry completely, you would need to block www.crackberry.com, m.crackberry.com, and t.crackberry.com since they have specified sites for tablets, smartphones, and full blown browsers.
If you find a site not blocking after enter its URL, go to that site and look in the Address Bar in Safari to make sure you're blocking the correct URL. Copy it if you need to and paste it into restrictions.
For very young children, or if you simply want to make sure nothing is accessible except what you specifically allow, you can disable everything and then only turn back on the sites you consider absolutely permissible. (Like Apple or Disney).
As with the blacklist, you might need to add variations, such as mobile versions, if a site has iPhone or iPad-specific URLs.
