UICavigation 표시 숨기기 UINavigationBar

Question

기본적으로 내 UINavigationBar의 배경색을 설정하려고하지만 아무 것도 표시하지 않습니다.

제발, 어떻게 해결할 수 있습니까?! 대단히 감사합니다 !!

이것은 viewDidLoad에 내 코드 :

[super viewDidLoad]; 



self.filteredContentList = [[NSMutableArray alloc] init]; 
// Do any additional setup after loading the view. 

self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 50, CGRectGetWidth(self.collectionView.frame), 30)]; 
self.searchBar.autocorrectionType = UITextAutocorrectionTypeNo; 
self.searchBar.placeholder = @"Search..."; 

[self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:CellIdentifier]; 
self.collectionView.backgroundColor = [UIColor whiteColor]; 

[self.collectionView addSubview:self.searchBar]; 
[self.view addSubview:self.searchBar]; 
[self.collectionView setContentOffset:CGPointMake(0, 44)]; 

[self.collectionView setContentInset:UIEdgeInsetsMake(80, 0, 0, 0)]; 

self.navigationController.navigationBar.backgroundColor = [UIColor greenColor];

이 아이폰 OS 7 잘 작동, 당신은 위의 코드에 적응 :

이

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)]; 
[navBar setBarTintColor:[UIColor greenColor]]; 

UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 50, CGRectGetWidth(navBar.frame), 30)]; 
searchBar.autocorrectionType = UITextAutocorrectionTypeNo; 
searchBar.placeholder = @"Search..."; 

[self.view addSubview:searchBar]; 
[self.view addSubview:navBar];
