다른 컨트롤러

Question

내가 다른 컨트롤러에 string을 전달하고에 문자열 값을 전달하는 것은

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 

CategoriesList *dvController = [[CategoriesList alloc] initWithNibName:@"CategoriesList" bundle:nil]; 

NSString *category=aBook.name; 
dvController.category=category; 
[self.navigationController pushViewController:dvController animated:YES]; 
[dvController release]; 

} 

그것은 내가 버튼을 제목에 있음을 설정하고 표시되지 않습니다 가장 쉬운

NSString *title=category; 
[titleButton setTitle:title forState:UIControlStateNormal]; 

Answer 1

방법은 CategoriesList에 사용자 정의 초기화를 만드는 것입니다 :

CategoriesList.h

@interface DetailViewController : UIViewController 
{ 
    NSString *category; 
} 

@property (nonatomic, retain) NSString *category; 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil category:(NSString *)categoryName; 

CategoriesList.m

@synthesize category; 

... 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil category:(NSString *)categoryName; 
{ 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) 
    { 
     self.category = categoryName; 
    } 
    return self; 
} 

... 

- (void)dealloc 
{ 
    [category release]; 
    [super dealloc]; 
}
