当我在调试区域中键入时，我的 Xcode（4.5 版）只显示第一个数字（或字符） - 如下所示：
2012-09-26 02:45:31.560 nn[731:303] Which numbers do you want to calculate Great Common Divisor?
1st=
4
2012-09-26 02:45:36.777 nn[731:303] 2nd=
6
2012-09-26 02:45:39.633 nn[731:303] your number is 45 and 66, and gcd is 3
它有什么问题？
虽然程序运行良好，但当我更改输出选项（所有输出、目标输出）时，我可以看到我的号码。
这是代码。
#import <Foundation/Foundation.h>
int main (int argc, char *argv[]){
@autoreleasepool{
int n1, n2;
int numerator, denominator, remainder, gcd;
numerator = 0;
denominator = 0;
remainder = 0;
gcd = 0;
NSLog(@"Which numbers do you want to calculate Great Common Divisor? \n 1st=");
scanf("%i", &n1);
NSLog(@"2nd=");
scanf("%i", &n2);
numerator = n1;
denominator = n2;
while (numerator % denominator != 0){
remainder = numerator % denominator;
numerator = denominator;
denominator = remainder;
}
gcd = denominator;
NSLog(@"your number is %i and %i, and gcd is %i", n1, n2, gcd);
}
return 0;
}
注意：这个问题突然出现（我以前能看到我输入的内容）。我检查了我所有的 mac，所有的 xcode 都是这样工作的。它们都只显示数字（或字符）的第一位。
