这就是我所理解的:您想询问 2 个数字和另一个由 arc4random 生成的数字,但是如果用户在接下来的十分钟内引入了相同的 2 个数字,则 arc4random 数字必须相等。
我将尝试将数字保存在其他变量中(例如 saveV1、saveV2 和 saveV3),并以 600 秒的时间间隔启动一个 NSTimer。NSTimer 的选择器将清除 saveVX 变量。所以这是结构:
1. Ask V1
2. Ask V2
3. Check if there are saved numbers and check if they are V1 == saveV1 and V2 == saveV2
4A. If they are the same: V3 = saveV3
4B. If they aren't: Generate V3
5. Save V1, V2, V3 in saveV1, saveV2 and saveV3.
这是你要求的吗?
编辑:这是代码:
//v1, v2, v3, saveV1, saveV2, saveV3 declared in the .h file
-(void) function
{
v1 = [[v1TextField text] intValue];
v2 = [[v2TextField text] intValue];
if(v1 == saveV1 && v2 == saveV2)
{
v3 = saveV3;
}
else
{
v3 = arc4random()%100; //This line generates a random number between 0 and 99.
[NSTimer scheduledTimerWithTimeInterval:600.0f target:self selector:@selector(deleteVs) userInfo:nil repeats:NO];
}
saveV1 = v1;
saveV2 = v2;
saveV3 = v3;
NSLog(@"V1: %d, V2: %d, V3: %d",v1,v2,v3);
}
-(void)deleteVs
{
saveV1 = 0;
saveV2 = 0;
saveV3 = 0;
//You can change this and put -1 to have 0 as a valid value of v1 and v2.
}
