目标C最大宏错误

我在目标C中看到了max宏的奇怪行为。具体来说,我的主函数中有以下代码:

NSArray* array = [NSArray array];
NSLog(@"[array count] - 1 = %d", [array count] - 1);
NSLog(@"MAX(0, [array count] - 1) = %d", MAX(0, [array count] - 1));
NSLog(@"MAX(0, -1) = %d", MAX(0, -1));

输出是:

[array count] - 1 = -1
MAX(0, [array count] - 1) = -1
MAX(0, -1) = 0

我用-save temps保存了预处理器输出,如下所示:

NSArray* array = [NSArray array];
NSLog(@"[array count] - 1 = %d", [array count] - 1);
NSLog(@"MAX(0, [array count] - 1) = %d", ((0) > ([array count] - 1) ? (0) : ([array count] - 1)));
NSLog(@"MAX(0, -1) = %d", ((0) > (-1) ? (0) : (-1)));

所有必要的括号都在那里,并且 [array count] - 1 没有副作用,所以通常的宏观问题不应该适用。知道怎么回事吗?
