我有这种方法,当被叫:
- (void)showContent
{
NSLog(@" 0 1 2 3 4 5 6");
for (int j = 0; j < rows; j++) {
for (int k = 0; k < columns; k++) {
MDLog(@"[%c]", board[j][k]);
}
NSLog(@"");
}
NSLog(@"---------------------------------------------------");
}
这应该创建一个空的6 x 7网格(对于Connect Four游戏),如下所示:
0 1 2 3 4 5 6
[ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ]
---------------------------------------------------
然而,Xcode控制台根本不打印它。它将每列垂直显示在彼此之上。其他有用的信息是我
int rows; // initializes to be 6
int columns; // initializes to be 7
char board[6][7];
Xcode以这种方式打印:
0 1 2 3 4 5 6

您可以连接每行的字符串并立即打印所有字符串。或者你可以使用printf()。 printf()不会添加换行符,因此会创建所需的结果。
- (void)showContent
{
NSLog(@" 0 1 2 3 4 5 6");
for (int j = 0; j < 6; j++) {
for (int k = 0; k < 7; k++) {
printf("[ ]");
}
printf("\n");
}
NSLog(@"---------------------------------------------------");
}
