So the problem is the following :

"Write a method for the Rectangle class called draw that draws a rectangle using dashes and vertical bar characters. The following code sequence 

Rectangle *myRect = [[Rectangle alloc]init];
[myRect setWidth : 10 andHeight : 3];
[myRect draw];

Would produce the following output : "

(i cant show you the picture but its a rectangle made out of "-" dashes and "|" bar characters. Dashes are for width and bar characters for height.)

I've started doing the method like this : 

{
int n;

for ( n = 1 ; n <= self.width ; ++n)
    printf ("-");

for ( n = 1 ; n <= self.height ; ++n){
    printf ("\n|");
        }
    printf("\n");

for ( n = 1 ; n <= self.width ; ++n){
    printf ("-");
}

But it seems like its not going to work like that , i cant get it to display the outer (|) lines . Could anyone help me on this one?

あなたはObjective-Cで作業していると思いますが、Cでテストした簡単なコードセットを次に示します。これは非常に簡単に変換できます。

void printRectangle(int width, int height)
{
     int n;
     int z;

     printf(" ");

     for (n = 1 ; n <= width ; n++)
        printf ("-");

     printf("\n");

     for ( n = 1 ; n <= height ; n++)
     {
        printf ("|");

        for(z = 1; z <= width; z++)
             printf(" ");

        printf("|\n");
     }

     printf(" ");

     for ( n = 1 ; n <= width ; ++n)
         printf ("-");

     printf("\n");
}

幅 = 10、高さ = 5 の出力

申し訳ありませんが、上記の受け入れられた回答が表示されませんでした。ただし、念のためこれは残しておきます。

私はObjective Cでテストしていませんが、試してみてください:)

for (int y = 0; y <= self.width; y++) {
    for (int x = 0; x <= self.width; x++) {
        if (x == 0 || y == 0 || x == self.width || y == self.height) {
            if (y == 0 || y == self.height) {
                printf("-");
            }
            else if (x == 0 || x == self.width) {
                printf("|");
            }
            if (x == 10) {
                printf("\n");
            }
        } else {
            printf(" ");
        }
    }
  }

これはJavaで書かれており、あなたのものに合わせていくつかの単語を変更しただけです. :)
