在编译《iphone开发秘籍》第八章的秘诀一的代码时碰到以下警告错误：
CGPoint randomPoint()
{
int half = 32;
int freesize = 240 - 2 * half;
return CGPointMake(random() % freesize + half, random() % freesize + half);
}
warning:No previous prototype for function "randomPoint"。如何取消这个警告错误呢？方法尝试了这两种都可以：
1.方法上加修饰符static
2.或者Project-Info -> TARGETS ->Build Settings -> LLVM GCC4.2 - Warnings组 -> Missing Function Prototypes Yes->No
