Soundcloud: SCLoginViewController overlaps status bar when presented from another view controller - ios

Question

For my iPhone app I want to implement the option to upload files to Soundcloud by making use of the CocoaSoundCloudAPI. In the instructions "How to use the SoundCloud API directly" it is explained how to modally present a loginViewController:
- (void)login {
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:
^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController =
[SCLoginViewController loginViewControllerWithPreparedURL:preparedURL
completionHandler:^(NSError *error){
if (SC_CANCELED(error)) {
NSLog(#"Canceled!");
} else if (error) {
NSLog(#"Ooops, something went wrong: %#", [error localizedDescription]);
} else {
NSLog(#"Done!");
}
}];
[self presentModalViewController:loginViewController
animated:YES];
}];
}
Now I replaced
[self presentModalViewController:loginViewController
animated:YES];
with
[self presentViewController:loginViewController
animated:YES
completion:nil];
because the first method is deprecated in iOS 7.
But the problem is that the Soundcloud loginViewController overlaps the status bar when presented in this fashion. And since I don't want to change the Soundcloud API I do not have the option to customize the loginViewController accordingly e.g. in its - viewDidLoad method (as suggested in many other posts on Stackoverflow).
Unfortunately there is a toolbar with a button on top the loginViewController. How can I configure my loginViewController from inside my own (presenting) view controller so that it won't overlap with the status bar when presented?

As mentioned in my comment to the original question I did not find a neat solution for this problem. However I managed to implement a workaround that does the job:
The basic idea is to add the SCLoginViewController as a child view controller of another custom view controller that is not part of the Soundcloud framework and that you can customize to your needs. This is my new login method that presents the login view controller:
- (BOOL)loginToSoundcloud {
BOOL __block success = NO;
[SCSoundCloud requestAccessWithPreparedAuthorizationURLHandler:^(NSURL *preparedURL){
SCLoginViewController *loginViewController;
loginViewController =
[SCLoginViewController loginViewControllerWithPreparedURL:preparedURL
completionHandler:^(NSError *error){
if (SC_CANCELED(error)) {
NSLog(#"Canceled!");
} else if (error) {
NSLog(#"Ooops, something went wrong: %#", [error localizedDescription]);
} else {
NSLog(#"Done!");
success = YES;
}
}];
/* BEGIN workaround for iOS7 bug:
when modally presenting a view controller it overlaps the status bar */
CBContainerVCToFixStatusBarOverlap *containerVC = [[CBContainerVCToFixStatusBarOverlap alloc] init];
[containerVC addChildViewController:loginViewController];
containerVC.view.backgroundColor = [UIColor clearColor];
if ([CBAppDelegate iOSVersionIs7OrHigher]) {
loginViewController.view.frame =
CGRectMake(loginViewController.view.frame.origin.x,
loginViewController.view.frame.origin.y + 20,
containerVC.view.frame.size.width,
containerVC.view.frame.size.height - 20);
} else {
loginViewController.view.frame =
CGRectMake(loginViewController.view.frame.origin.x,
loginViewController.view.frame.origin.y,
containerVC.view.frame.size.width,
containerVC.view.frame.size.height);
}
[containerVC.view addSubview:loginViewController.view];
/* END workaround for iOS7 bug */
[self presentViewController:containerVC
animated:YES
completion:nil];
}];
return success;
}
To check for the iOS version I implemented the following method in my CBAppDelegate:
+ (BOOL)iOSVersionIs7OrHigher {
return floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1;
}
CBContainerVCToFixStatusBarOverlap is a simple view controller class with no additional methods and only one declared property. This is the content of CBContainerVCToFixStatusBarOverlap.h:
#interface CBContainerVCToFixStatusBarOverlap : UIViewController
#property (strong, nonatomic) IBOutlet UIView *containerView;
#end
