objective c - Overreleasing issue and Zombies -

-

This program crashes if I want to delete the release statements. I think I am overreleasing and realized that quickly But, just to test the zombies, I changed them to (NSAMBJANABLE = ESAS and CFGNElval = 16) and the program ran fine and did not throw exceptions.

What gives? I thought that turning on the corpse just told me whether I am a doofus ... it is not okay. 

  #import "AppController.h" @ Implementation AppController - (IBAction) countCharacters: (ID) sender {// does a button do this? If (! [Sender Hackindfclass: [NSBitton class]]) {NSLog (@ "% @ is not a button", sender); Return; } / Proceed NSString * userString = [textField stringValue]; NSNumber * Calculation = [NSNumber Numbers: [UserString Length]]; NSString * outputString = [NSString stringWithFormat: @ "'% @' has% @ characters.", Userstring, counting]; // [userString release]; // [counting continue]; [Labelfield set string value: outputstring]; // [output string release]; } @end

That's because you try to leave something You do not have any reference to them). Their ownership is given to the "nearest" NSAIDRepipal.

You can read about object ownership. Generally, you are not the owner if you have not called yourself to create an object in the form of a quick reference, or if you have not retained by Maintain with an object you become an owner; Calling Release means you owe ownership (and will prohibit the object if it does not have any other owner).

You should not not not owned by you without releasing your current code exactly what you need.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
