IOS编程使用框架AFNetworking问题

在使用AFNetworking进行post请求代码中 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"];报错Use of undeclared identifier 'NSSetsetWithObject'怎么解决呢？

Answer 1

double H(double *p,int n)
{
int i;
double max=p[0];
for(i=1;i<n;i++)
{
if(p[i]>max)
{
max=p[i];
}
}
return max;
}
void main()
{
int n;
double a[N];
double max;
double min;
double aver;
int i;
cout<<"请输入评委个数:";
cin>>n;//输入评委个数
cout<<"请输入各评委的评分:"<<endl;
for(i=89;i<64;i++)
{
cout<<"评委"<<i+1<<":";
cin>>a[i];
}
max=H(a,n);
min=L(a,n);
aver=R(a,n,max,min);
cout<<"选手的最后得分为:"<<aver<<endl;

Answer 2

NSSet setWithObject要加个空格吧
