What is the best Reference for Objective-C

I am trying to learn Objective-C to develop for iphone and ipad by following a stanford course, and i need to understand more and more about Objective-C , i know the documentations that xcode provides , but it's not quite enough for me actually, I hope that someone provide a link for a good book to download.
best Regards

For beginners this book
Programming in Objective-C (5th Edition) (Developer's Library)
seems to do a good job introducing the language and environment.
Wayne I agree that the book you mention is a good one but might be a bit to advanced for someone just starting out learning Objective-C.

what is the best book of objective c and from where i can download it?

Before purchasing a book be sure to exhaust the excellent resources on the Apple Developer Site. There are quite a few guides, references, and samples for Objective-C.
Learning Objective-C: A Primer
The Objective-C Programming Language
Object-Oriented Programming with Objective-C
etc.
If you are developing for Mac or iOS, there are plenty of other documents describing the frameworks, including the Cocoa Fundamentals Guide, iOS App Programming Guide, etc.

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

What is the best practice for creating master pages and styles with translated text?

I format translated text all the time for my company. I want to create a set of master pages and styles for each language and then import those styles into future translated documents. That way, the formatting can be done quickly and easily.
What are the best practices for doing this? As a company this has been tried in the past, but without success. I'd like to know what other people are doing in this regard.
Thank you!

I create a master template that is usually void of content, with the exception I define as many of the paragraph styles I believe can/will be used with examples of their use in the body of the document--a style guide for that client. When beginning a new document for that client, I import those styles from the paragraph styles panel.
Exception to this is when in a rush I begin documentation first, then begin new work. Then in the new work, I still pull in those defined paragraph and or object styles via their panels into the new work.
There are times I need new styles. If they have broader applicability than a one-off instance or publication, then I open the style template for that client and import that style(s) from the publication containing the new style(s) and create example paragraphs and usage instructions.
Take care, Mike

WhatÃÂ¢ÃÂÃÂs the best practice for this scenario?

Hi,
My users want the ability to change the WHERE and/or ORDER BY clause at runtime. They may define user preferences on each screen ( which is bind to a view object). They want to see the same records based on WHERE/ORDER BY defined on the last visit. That is why I keep the users preferences and load the screen based on that, using :
View.setWhereClause(...);
View.setOrderByClause(...);
View.executeQuery();
This works good when only one user working with the application but faced low performance when more than one user working with the application.
What are the points to increase the performance and what is the best practice for this scenario?
Thanks for your help in advance.

Sung,
I am talking only about 2 users in my testing. I am sure i missed something but could not recognize that.
This page is my custom query page including a tag to instantiate app module in stateful mode at the top <jbo:ApplicationModule..> and a tag to instantiate data source <jbo:Datasource...> and release tag at the bottom <jbo:ReleasePageResources..> and some java code in the middle(body). The java code constructed the query statement and then fires the query to set the view object based on the query statement using the above methods.
So, I am facing very slow performance(speed) when two clients load this page at the same time. Looks like the entire application locks for others when one client load this page and fire the query. i realized the battle neck is where executeQuery() is executing.
what do you think.
Thanks in advance for your comments.

What is the best program for designing event flyers? I am looking for something basic and simple.

Poor old Photoshop® is forever being put down when it comes to layout work, but it is perfectly capable, and can output a high quality print PDF the printer will be perfectly happy with. OK you don't have the text flow between columns bells and whistles of InDesign and [spit] Publisher, but if you have a $10/month Photoshop/Lightroom subscription, instead of the $50/month full subscription, don't think you can't do a perfectly good flyer or poster.

What are the best practies for naming symbols (spaces OK,etc.)?

What are the best practices for symbol naming for ease, flexibility, & to avoid "gatchas" down the road?
Does it make any difference if one includes spaces in the names of symbols? Are there any widely followed conventions for naming them like using camelCase or underscores?
Thanks!

Hi Gina D 3333,
Best-practice file-naming conventions for PDF files are the same as for any other file. I found this article on Apple's website that contains some useful pointers to consider when you're naming files that will be used on multiple platforms: OS X: Cross-platform filename best practices and conventions
I hope this helps!

What's the best photograph for a no background image?

I am about to photograph some products and would like to make a set up where I can photograph each of the products in the same setting/lighting. Then, when I go to open/edit them in PhotoshopCS4, I can take out the background and have just the image. Then, I can place that image ontop of any background I want. There is one bad thing. Some of these have a clear top where you can see thru them. Does or will that make a difference?
I want to set it up like they do for the weather on television, have a blue background and erase all of the blue showing. Then the only thing showing in the end is the digital background that was added in by computer and the weatherman(unless he's wearing a blue tie, in which case you can see the info through him). But my question still stands, what is the best setting for this and/or background color, how should the photographs be taken and then opened and edited(removing the background) using PhotoshopCS4?
We have a lighting set up, a 30" x 30" x 30" light tent setup, 3 lights with Pro Light Reflectors(one on the left, one on the right and one on top), 1 white and 1 black background and a box to place the images on. I'm using a Nikon D100.
Attached in a photo example.
This was taken with the black background and you can see the black through the bottle. I erased all of the surrounding black, but the dark shades still show on the sides.
Any help will be appreciated.
Sean

The whole point is that these photographs will be used for the book, manuals, magazines, ads... The backgrounds will not always be the same. That's my main problem. I am trying to figure out a way for the glass of the bottles to be "glass" images or "see through" so that when the photograph is placed on a background of, let's say, flowers, the flowers would show through. The edges of the glass are still solid and the flowers would not show thru them, but...
Is this type of thing possible for printing quality photographs?
Note - In the attched photo, it can be seen that the black background can be seen the plastic cap.

What's the best approach for handeling about 1300 connections in Oracle.

What's the best approach for handling about 1300 connections in Oracle 9i/10g through a Java application?
1.Using separate schema s for various type users(We can store only relevant data with a particular schema. Then No. of records per table can be reduced by replicating tables but we have to maintain all data with a another schema Then we need update two schema s for a given session.Because we maintain separate scheama for a one user and another schema for all data and then there may be Updating problems)
OR
2. Using single schema for all users.
Note: All users may access the same tables and there may be lot of records than previous case.
What is the Best case.
Please give Your valuable ideas

It is a true but i want a solution from you all.I want you to tell me how to fix my friends car.

What is the best artical for understanding Data Pump

Hi,
What is the best artical for understanding the relationship / dependency of NETWORK_LINK with FLASHBACK_SCN or FLASHBACK_TIME .
Why it is manditory to have NETWORK_LINK , when we are using FLASHBACK_SCN or FLASHBACK_TIME.
Can some one explain the internal for that dependency
Thanks
Naveen

There's no direct dependency between NETWORK_LINK and FLASHBACK_SCN and FLASHBACK_TIME
As noted in this Oracle doc,
If the NETWORK_LINK parameter is specified, the SCN refers to the SCN of the source database
FLASHBACK_SCN and FLASHBACK_TIME are mutually exclusive.

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you
Regards,
Eduardo

What's the best SSD for a Macbook Pro 13" Mid 2010?

Hello.
I will upgrade my 2010 Macbook Pro. I need to know what's the best SSD for my Macbook Pro. I was thinking about those:
- Kingston SSDNow V+200 (SVP200S37A/120G) - 120 GB
- CRUCIAL SSD M4 128 GB
- CORSAIR SSD Force Series GS 128 GB
- SAMSUNG SSD 840 Series Basic 2.5" - 120 GB (MZ-7TD120BW)
- CRUCIAL SSD interno Crucial v4 - 128 GB
Those are the easiest to find on Portugal.

It is my understanding that SATA III is backwards compatible to SATA II so that should not be an issue for your selection process.
As an aside, you might be interested to know that your MBP can now have 16 GB RAM installed.
