ARC mechanism, do you need to worry about memory overflow?

Who told you not to experience AH: The truth is the following example

int main (int argc, const char * argv[])

{

@autoreleasepool {

person * p = [[Person alloc] init];

Nsmutablearray * array = [[Nsmutablearray alloc] init];

When an object is stored in the collection, its strong pointer is saved by default

[Array addobject:p];

When a single object is removed from the collection, a strong pointer to the object is released

[Array removeobject:p];

[Array removeallobjects];

Array = nil;

p = nil;

NSLog (@ "ADFASDF");

}

return 0;

}
