NSLog的使用與C++中的Objective-C++

Question

我有一個程序結構類似以下對象：

int firstFunction(unsigned char *firstValue, int s, int t) 
{ 
     CppFunction *cpp=CppFunction::create(firstValue, s, t, 0); 

} 

我怎麼會拿的cpp的NSLog？

Answer 1

可以從CppFunction記錄某些值，檢查示例

int firstFunction(unsigned char *firstValue ,int s,int t) 
{ 
    CppFunction *cpp=CppFunction::create(firstValue, s, t,0); 

    NSLog(@"Log some integers %d", cpp->SomeInteger); 
    //charArray[100] for example 
    NSLog(@"Log some char array %s", cpp->charArray); 

    //or for example log a string description function 
    //myDescription will return a custom char array description of your class 
    NSLog(@"Log some char array %s", cpp->myDescription()); 
}
