Question

我在我的IAP实时应用中遇到此问题。我很紧张，因为它错过了收入机会。任何人都可以帮我理解这个崩溃报告吗？

没有多少去那里。

using namespace std;
void minimum(int[], int);
void maximum (int[], int);
void average(int[], int);
void median(int[], int);
void mean(int[], int);
void sort(int[], int);


int ra()
{
int r = rand() % 1000;
return r;
}

int main ()
{

srand(time(NULL));
ra();
int array[20];
int num=20;
for (unsigned int i = 0; i < num; i++)
{
array[i] = ra();
cout << "Index: " << i << ", random number: " <<  array[i] << endl;
}

minimum();
new_array[20];
num=20;
for (unsigned int i = 0; i < num; i++)
{
new_array[i] = new_array();
cout << "Index: " << i << ", random number: " <<  minimum << endl;

} 
return 0;

}

void minimum(int new_array[], int num)
{
for (unsigned int i = 0; i < num; i++)
if (new_array[i] minimum)
minimum = new_array[i];
cout << "Maximum value: " << minimum << endl;


}   
void maximum (int new_array[], int num)
{  
for (unsigned int i = 0; i < num; i++)
if (new_array[i] > maximum)
maximum = new_array[i];
cout << "Maximum value: " << maximum << endl;


return 0;

}

void median(int new_array[], int num)
{
//CALCULATE THE MEDIAN (middle number)
if(num % 2 != 0){// is the # of elements odd?
int temp = ((num+1)/2)-1;
cout << "The median is " << new_array[temp] << endl;
 }
 else{// then it's even! :)
 cout << "The median is "<< new_array[(num/2)-1]<<new_array[num/2]< endl;             
 }
 mean(new_array, num);

 }

 void sort(int new_array[], int num)
 {
 //ARRANGE VALUES
 for(int x=0; x<num; x++){
 for(int y=0; y<num-1; y++){
 if(new_array[y]>new_array[y+1]){
 int temp = new_array[y+1];
 new_array[y+1] = new_array[y];
 new_array[y] = temp;
 }
 }
 }
 cout << "List: ";
 for(int i =0; i<num; i++){
 cout << new_array[i] << " ";
 }
 cout << "\n";
 median(new_array, num);

 }


void average_(int new_array[], int nums)
{
float sum;
for (unsigned int i = 0; i < 20; ++i)
{   
 sum+=num;
}
 cout << "Average value: " << average_/num << endl;   

}          


Please tell the necessary corrections

如果我是你，我会仔细查看您的0 libobjc.A.dylib objc_msgSend + 16 1 StoreKit __34-[SKProductsRequest _handleReply:]_block_invoke + 52 SKProductRequestDelegate方法。虽然它没有出现在回溯中，但有时它们并非100％可靠。

要寻找的另一件事是查看该委托是否以某种方式被释放。 -productRequestDidReceiveResponse:中的崩溃通常是由于这一点。你在使用ARC吗？

这篇文章应该出现在每个ObjC编码器的阅读清单上：
