objective c - Few questions on iphone memory management and cocos2d -

-

I'm working on my first app and have some questions on memory management.

The first question:

I am working on an introduction view that looks like this 

  #import "Intro_Scene.h" #import "Main_Menu.h" #import "Label.h" @ Implementation Intro_Scene @ synthesis logo, label; - (id) init {self = [super init]; If (self! = Zero) {// Load logo image and set status logo = [Sprite Spit Withfile: @ "Awalogo page"]; Logo.position = CCP (-50, 0); Logo. scale = 1.8f; [Self combine: logo]; // Logo creates 3 actions for the Sprite ID verb .00 [[Move to action; Duration: 0 Position: CCP (160,270)]; ID verb 1 = [duration of the FedEd verb: 3]; ID Action 2 = [Fadeout Actionwidth Period: 3]; // Logos Runs Functions [Logos Run Action: [Sequence Action: Action 0, Action 1, Action 2, Zero]]; // Amendment Scein Method of Change to switch views in the main menu within 6 seconds of learning. [Self Schedule: @Silctter (Transit Space) Interval: 6.0f]; // creates a label and gives it space, alternative view label = [label labelwith string: @ "alternative views" fontname: @ "wordana" font size: 22]; Label.position = CCP (160, 120); [Self-combined: label]; } Healthy return; } // method has introduced its functions after the introduction, after 6 seconds, it changes the scene - (zero) changes.Secine {[remove self: bridge of people: yes]; [Remove self: label cleaning: yes]; Main Menu * Main Menu = [Main Menu Node]; [[Director shared director] Replaced Sassine: Main Menu]; } - (zero) dealloc {[TextureMgr Shared Layer Mix] Deleted Inappropriate Text]; [Label release]; [LOGO RELEASE]; [Super DeLoc]; } @ And

Do I have released everything properly, and have leaks? I participated in the equipment several times and did not get any leak and found out about 2 MB memory, is it the amount or expected amount?

Question 2:

My main menu is set in this way 

  #import "Main menuH" #Import "Sprite." #import "cocos2d.h" @ Implementation Mainman @ Syntysize Background, ControlLayer; - (id) init {self = [super init]; If (self! = Zero) {// Make default background for main menu, including directional pad and highlight box background = [Sprite Spit WithFile: @ "Main Maneu_bg.png"]; Background.position = CCP (160,240); [Self compound: background]; // Later controls the control in the main menu, the control level displays the class and controls the directional pad and selector. ControlLayer * Layer = [[ControlLayer Elok] Init]; Self.controlLayer = Layer; [Release layer]; [Adding Child: ControlLayer]; } Healthy return; } - (Zero) Delok {[Easily Remove Child: Background Cleanup: Yes]; [[TexturMG shared shared mix] deleted texture used]; [Background release]; [Control release]; [Super DeLoc]; } @end

Once again am I doing everything correctly? The layer controller I'm adding to this scene is the directional pad sprite that the user uses to navigate menus. In the instrument also it confirms that there is no memory leak, and it uses 4.79 MB of memory. Once again this is a reasonable amount? I would most likely change the possibility to use the Atlasprit and Atlasstrost manager to save the message.

I am new in Cocos 2D, so if you see that I am saying anything wrong! I wanted to fix bad habits in the early stages and if you have any tips in the future for memory management please share.

Do not issue logos, labels or backgrounds You could not copy / copy / keep them new, So you do not keep them yourself and do not release them.

I think the controllers have properties to maintain the property of the liar? If not, then you probably mean to do this.

In general, I used to suggest two things to move forward.

  1. Read and understand
  2. Turn on your code. It is available in Xcode 3.2 through Build-> Build and Analysis It will help detect these memory problems.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
