在xcode中显示数组

Question

我正在尝试显示一个数组，其中包含数字（“prime”）的不同因子。但不是给我的int数，我总是得到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

更换

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

与

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

的问题是，你只打印数组的索引，而不是价值。
