在xcode中顯示數組

Question

我正在嘗試顯示一個數組，其中包含數字（「prime」）的不同因子。但不是給我的int數，我總是得到0,1,2,3,4,5，...。

 factors.text = @""; 

     int factorsNumber; 

     NSMutableArray *array; 
     array = [NSMutableArray arrayWithCapacity:5]; 

     for (factorsNumber=1; factorsNumber<=prime; factorsNumber++) { 
      if (prime%factorsNumber == 0) { 
       [array addObject:[NSString stringWithFormat:@"%d", factorsNumber]]; 
      } 

     } 


     for (int i = 0; i < [array count]; i++) { 

      [array replaceObjectAtIndex:1 withObject:@"4"]; 

      NSString *temp = [NSString stringWithFormat:@"%d, ", i, [[array objectAtIndex:i] intValue]]; 
      factors.text = [factors.text stringByAppendingString:temp]; 
     } 

Answer 1

更換

NSString *temp = [NSString stringWithFormat:@"%d, ", i, [[array objectAtIndex:i] intValue]]; 

與

NSString *temp = [NSString stringWithFormat:@"%d, ", [[array objectAtIndex:i] intValue]]; 

的問題是，你只打印數組的索引，而不是價值。
