self.splitViewController.navigationController pushViewController can't work - objective-c

Question

UIsplitViewController can't pushViewController, only the master view or only detail view can pushViewController inside it's view. I wan't to push a new view int the current UIsplitViewController. The UIsplitViewController is in a UITabBarController.
How to solve it?

Answer 1

self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
[MLTool pushView:self newView:USER_VIEW];
+(id)pushView:(UIViewController*)view newView:(NSString*)newView{
UIViewController *svc = [view.storyboard instantiateViewControllerWithIdentifier:newView];
//NSAssert(svc, #"pushView nil");
[view.navigationController pushViewController:svc animated:YES];
return svc;
}
- (void)viewWillAppear:(BOOL)animated{
SplitProductView* split=(SplitProductView* )self.splitViewController;
[split resetSplit: [[UIApplication sharedApplication] statusBarOrientation]];
//self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay
}
-(void)resetSplit :(UIInterfaceOrientation)toInterfaceOrientation {
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
//TODOX:iphone
if (isPad)
{
if(UIInterfaceOrientationIsPortrait(toInterfaceOrientation)){
self.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay;
}
else{
//if (self.displayMode == UISplitViewControllerDisplayModePrimaryOverlay)
{//ios的bug,必须这三行,不然左边有黑边
// if (SYSTEM_VERSION_MORE_THAN(#"8.0"))
{
self.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
self.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible;
self.preferredDisplayMode = UISplitViewControllerDisplayModeAutomatic;
}
}
}
}
}
}
