//*     ARC_MRC混合编程    *
//************************

//Dog和person类是之前的MRC编译的(MRC是手动管理内存,我们在使用第三方库的时候,有时很多都是MRC编译的文件,在编译出错时可以使用一下方法)
//MRC -->Manual Reference Counting
//ARC -->Automatic Reference Counting
//一般将MRC编译的文件导入到ARC环境中运行的时候,需将MRC的文件编译器标志改一下,
//在Build Phases->Compile Sources->Compiler Flag中添加"-fno-objc-arc",添加时没有双引号
//将ARC放在MRC环境中时添加-fobjc-arc
int main(int argc, const char * argv[]) {
@autoreleasepool {
Person *person = [[Person alloc] init];
Dog *dog = [[Dog alloc] init];
person.dog = dog;
}
return 0;
}
