NSString定義變量進入格式

Question

我正在做作業，要求我返回一個完整的句子，指出我最喜歡的奶酪。我已經寫出了下面的代碼，但我不確定在哪裏定義cheeseName。另外，如何測試代碼以查看它是否返回正確的cheeseName，NSLog()？

這是我的.m文件

#import "StringCheese.h" 

@implementation StringCheese 

- (NSString *) favoriteCheeseStringWithCheese:(NSString *)cheeseName { 
/* WORK HERE */ 
return [NSString stringWithFormat:@"My favorite cheese is %@.", cheeseName]; 
/My answer is the code above/ 
} 

這是我的其他.m文件：

#import <XCTest/XCTest.h> 
#import "StringCheese.h" 

@interface StringCheeseTests : XCTestCase 

@property (nonatomic, strong) StringCheese *stringCheese; 

@end 

@implementation StringCheeseTests 

- (void)setUp 
{ 
[super setUp]; 
// Put setup code here. This method is called before the invocation of each test method in the class. 
self.stringCheese = [[StringCheese alloc] init]; 
} 

- (void)tearDown 
{ 
// Put teardown code here. This method is called after the invocation of each test method in the class. 
[super tearDown]; 
} 

- (void)testThatCheeseFavoritingWorks { 
NSString *ricottaString = @"ricotta"; 
NSString *favoriteCheese = [self.stringCheese favoriteCheeseStringWithCheese:ricottaString]; 

XCTAssertEqualObjects(favoriteCheese, @"My favorite cheese is ricotta.", @"Incorrect favorite cheese string returned."); 

NSString *goatString = @"goat"; 
favoriteCheese = [self.stringCheese favoriteCheeseStringWithCheese:goatString]; 
XCTAssertEqualObjects(favoriteCheese, @"My favorite cheese is goat.", @"Incorrect favorite cheese string returned."); 

}

要打印出增值：

NSLog(@"%@", favouriteCheese); 

在結束 - （無效）testThatCheeseFavoritingWorks方法，因此它看起來像：

- (void)testThatCheeseFavoritingWorks { 
NSString *ricottaString = @"ricotta"; 
NSString *favoriteCheese = [self.stringCheese favoriteCheeseStringWithCheese:ricottaString]; 

XCTAssertEqualObjects(favoriteCheese, @"My favorite cheese is ricotta.", @"Incorrect favorite cheese string returned."); 

NSString *goatString = @"goat"; 
favoriteCheese = [self.stringCheese favoriteCheeseStringWithCheese:goatString]; 
XCTAssertEqualObjects(favoriteCheese, @"My favorite cheese is goat.", @"Incorrect favorite cheese string returned."); 

NSLog(@"%@", favoriteCheese); 
}
