在ARC Objective C中输出参数

- (void)getMinMax:(NSInteger *)min andMax:(NSInteger *)max {
    NSInteger a = 5;
    NSInteger b = 10;

    if (a < b) {
        *min = a;
        *max = b;
    } else {
        *min = b;
        *max = a;
    }
}

NSInteger min, max;
[self getMinMax:&min andMax:&max];
NSLog(@"Min: %ld, Max: %ld", (long)min, (long)max);

Min: 5, Max: 10
