我想訪問一個UIImage實例變量並顯示它在UIImageView。當我嘗試NSLog的路徑時,我得到空。我可以手動顯示通過IB一個事先知情同意,但我想通過嚴格的代碼訪問UIImage實例變量,並顯示它在UIImageView

#import "Deck.h" 
#import "Card.h" 

@implementation Deck 

@synthesize cards; 

- (id) init 
{ 
    if(self = [super init]) 
    { 
     cards = [[NSMutableArray alloc] init]; 

     NSInteger aCount, picNum = 0; 

     for(int suit = 0; suit < 4; suit++) 
     { 
      for(int face = 1; face < 14; face++, picNum++) 
      { 


       NSString *fileName = [NSString stringWithFormat:@"card_%d", picNum]; 
       NSString *path = [[NSBundle mainBundle] pathForResource:fileName   
        ofType:@"png"inDirectory:@"/cards"]; 

       NSLog(@"%@", path);       //outputs correctly 

       UIImage *output = [UIImage imageNamed:path]; 

       NSLog(@"%@", output);      //outputs null 

       Card *card = [[Card alloc] initWithFaceValue:(NSInteger)face 
               countValue:(NSInteger)aCount 
               suit:(Suit)suit 
               cardImage:(UIImage *)output]; 

       [cards addObject:card]; 
      } 

     } 
    } 
    return self; 
}

你不這樣做不必包含圖像的所有路徑,如果您只需輸入名稱,Xcode就會自動查找它。
