ios - 在 Cocoa 中组合多个字符串

Question

我希望能够将每个索引组合起来，这样我就可以得到@"生物老师A BK 1"，但是到目前为止我一直没有成功。到目前为止，这是我所拥有的，但我不知道从这里去哪里。

@interface ListTableViewController () <UISearchDisplayDelegate>

@property (strong, nonatomic) NSArray *className;
@property (strong, nonatomic) NSArray *teacherName;
@property (strong, nonatomic) NSArray *blockNumber;

@end

@implementation ListTableViewController

- (void)viewDidLoad {

    [super viewDidLoad];
    self.className = [NSArray arrayWithObjects:
                  @"Biology",
                  @"English III",
                  @"Chemistry",
                  @"Algebra II",
                  @"Morality", nil];

self.teacherName = [NSArray arrayWithObjects:
                    @"Teacher A",
                    @"Teacher B",
                    @"Teacher C",
                    @"Teacher D",
                    @"Teacher E", nil];

self.blockNumber = [NSArray arrayWithObjects:
                    @"BK 1",
                    @"BK 3",
                    @"BK 6",
                    @"BK 2",
                    @"BK 1", nil];
}

它会起作用:

   for (int i = 0 ; i< self.className.count; i++)
    {
      NSString *temStr = [NSString stringWithFormat:@"%@ %@ %@",[self.className objectAtIndex:i] ,[self.teacherName objectAtIndex:i],[self.blockNumber objectAtIndex:i] ];
      NSLog("%@", tempStr);
    }
