如果UIApplicationMain（）永远不会返回，那么自动释放池何时被释放？ [英] If the UIApplicationMain() never returns then when does the autorelease pool gets released?
问题描述
代码：
int main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil);
[pool release];
return retVal;
}
Apple的文档清楚地指明：
Apple's doc clearly specifies:
返回值：
即使指定了整数返回类型，此函数也不会返回。当用户通过按Home键终止iPhone应用程序时，应用程序会立即通过调用退出系统函数退出，参数为零。
Return Value: Even though an integer return type is specified, this function never returns. When users terminate an iPhone application by pressing the Home button, the application immediately exits by calling the exit system function with an argument of zero.
其次，在
int UIApplicationMain（
int argc，
char * argv []，
NSString * principalClassName，
NSString * delegateClassName
）;
我们如何从UIApplication子类访问argv？
Secondly, in
int UIApplicationMain (
int argc,
char *argv[],
NSString *principalClassName,
NSString *delegateClassName
);
how can we access the argv from our UIApplication subclass?
推荐答案
自动释放池不会被释放。相反，操作系统只是从内存中删除你的应用程序。
The autorelease pool doesn't get released. Instead, the OS simply removes your application from memory.
