[的UILabel setImage：]：無法識別的選擇發送到實例

Question

我用調試器和突破點，以針點下來哪一行代碼，我收到，我會告訴你的錯誤...

for (NSString *s in golferFourIconCounter) { 

     if(s != nil) { 
      int sint = [s intValue]; 
      switch (sint) { 
       case 1: 
        iconNum = @"Num1.png"; 
        break; 
       case 2: 
        iconNum = @"Num2.png"; 
        break; 
       case 3: 
        iconNum = @"Num3.png"; 
        break; 
       case 4: 
        iconNum = @"Num4.png"; 
        break; 
       case 5: 
        iconNum = @"Num5.png"; 
        break; 
       case 6: 
        iconNum = @"Num6.png"; 
        break; 
       case 7: 
        iconNum = @"Num7.png"; 
        break; 
       case 8: 
        iconNum = @"Num8.png"; 
        break; 
       case 9: 
        iconNum = @"Num9.png"; 
        break; 

       default: 
        break; 
      } 

      switch (ids) { 
       case 0: 
        imageTitle = @"GolfEagle.jpg"; 
        break; 
       case 1: 
        imageTitle = @"Birdie.png"; 
        break; 
       case 2: 
        imageTitle = @"Par.png"; 
        break; 
       case 3: 
        imageTitle = @"Bogey.png"; 
        break; 
       case 4: 
        imageTitle = @"Double-Bogey.png"; 
        break; 
       case 5: 
        imageTitle = @"Triple-Bogey.png"; 
        break; 
       case 6: 
        imageTitle = @"GolfSandie.png"; 
        break; 
       case 7: 
        imageTitle = @"Greenie.png"; 
        break; 
       case 8: 
        imageTitle = @"Polie.png"; 
        break; 
       case 9: 
        imageTitle = @"Dart.png"; 
        break; 
       case 10: 
        imageTitle = @"Three-Jack.png"; 
        break; 
       case 11: 
        imageTitle = @"Arnie.png"; 
        break; 
       case 12: 
        imageTitle = @"Ladie.png"; 
        break; 
       case 13: 
        imageTitle = @"Barkie.png"; 
        break; 
       case 14: 
        imageTitle = @"Hole-In-One.png"; 
        break; 
       case 15: 
        imageTitle = @"Fairway.png"; 
        break; 
       default: 
        break; 
      } 

      iid = iid+41; 

      NSLog(@"%d --- %@",iid, iconNum); 
      [(UIImageView*)[self.view viewWithTag:iid] setImage:[UIImage imageNamed:iconNum]]; 

      iid = iid-41; 
      int rr = 401900; 
      rr++; 
      rr = rr+iid; 

      [(UIImageView*)[self.view viewWithTag:rr] setImage:[UIImage imageNamed:imageTitle]]; 
      iid++; 
     } 

     ids++; 
    } 

的代碼失敗在這個代碼特定行...（朝的結束for循環）

[(UIImageView*)[self.view viewWithTag:iid] setImage:[UIImage imageNamed:iconNum]]; 

它沒有任何意義，因爲我得到的錯誤 - （的UILabel setImage）當我清楚地使用UIImageView的我的代碼？

這裏是獲取調試nsloged ...

Answer 1

我與標籤71或72.檢查您的故事板或筆尖的一個UILabel如果你真的遇到問題，你可以還追查編程，使其更容易找到：

UILabel *labelToChange = (UILabel *)[self.view viewWithTag:71]; 
labelToChange.backgroundColor = [UIColor greenColor]; 

當你在它，爲什麼不說第一大長開關切換到一個簡單的一行？

if (sint > 0 && sint < 10) iconNum = [NSString stringWithFormat:@"Num%d.png", sint];
