copied!<p>This code is basically determining what the iOS is and selecting the correct method call to set the <code>tintColor</code> of the navigationBar. See comments in code below </p> <pre><code>/* This is basically getting the systemVersion of the device so 7.0.1 - as this is returned as an NSString the user is separating this string based on the string "." which will place each string into the array. so you will have 3 objects in this array of "7", "0", "1" */ NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."]; /* Once we have separated this string into the array we are getting the first object in that array so index `0` which will return a string at which point we are converting the string "7" to an intValue and comparing it to the int 7. So if that value is 7 or greater return TRUE */ if ([[ver objectAtIndex:0] intValue] >= 7) { /* The value was TRUE so lets use the iOS 7 way of setting the tintColor. We do this by setting barTintColor for the navigationBar and because in iOS 7 the navigationBar can be translucent - by default this is YES but because we are setting to a color we want we need to set this to NO because we don't want to have it translucent. */ self.navigationController.navigationBar.barTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; self.navigationController.navigationBar.translucent = NO; } else { /* If all fails in the if statements conditional check we must be on something that is below iOS 7 so use the old way of things and just set the tintColor */ self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; } </code></pre> <p>Just so you know this doesn't work. If you are going to use this change it to:</p> <pre><code>if (floor(NSFoundationVersionNumber) => NSFoundationVersionNumber_iOS_7_0) { self.navigationController.navigationBar.barTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; self.navigationController.navigationBar.translucent = NO; } else { self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; } </code></pre> <p>this is because <code>if ([[ver objectAtIndex:0] intValue] >= 7)</code> will return FALSE even if iOS 7.</p> <p>To set the toolbar you could use the same method but replace:</p> <pre><code>self.navigationController.navigationBar.barTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; self.navigationController.navigationBar.translucent = NO; </code></pre> <p>with</p> <pre><code>[toolbar setBarTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"dropdownbar"]]]; [toolbar setTranslucent:NO]; </code></pre> <p>and replace </p> <pre><code> self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"top_bar"]]; </code></pre> <p>with</p> <pre><code> [toolbar setTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"dropdownbar"]]]; </code></pre>
