UIImage and Memory

Vladimir Boychentsov — Thu, 10 Jun 2010 11:43:22 +0000

+[UIImage imageNamed:]
• Reads the ﬁle, uncompresses it, caches result
• Cached copy of data is kept even if the UIImage is deallocated
• Low memory condition causes cache to be purged.
• No direct control over when cache is purged.
• Use for small frequently drawn images.

+[UIImage imageWithContentsOfFile:]
• Just reads enough of ﬁle to determine if it can open the ﬁle.
• Reads and uncompresses the ﬁle each time it draws. Uses uncompressed size worth of memory only temporarily.
• Assigning a UIImage created this way to a UIImageView or as the contents of a CALayer also causes it to read and uncompress the ﬁle. The UIImageView or CALayer keep the expanded version.

Memory Usage (in MB) 8.6 MB image used with UIImageView

	imageNamed	imageWithContentsofFile
Initial	2.46	2.46
Load UIImage	11.12	2.51
Assign to UIImageView	11.09	11.09
Remove from UIImageView	11.12	2.51

Memory Usage (in MB) 8.6 MB image used with UIView subclass (stored in instance variable and drawn with drawinRect: )

	imageNamed	imageWithContentsofFile
Initial	2.73	2.73
Load UIImage	11.38	2.78
Assign to UIImageView	11.81	3.20
Remove from UIImageView	11.84	3.04

Old news “Apple Project In Ukraine”

Vladimir Boychentsov — Fri, 12 Jun 2009 11:53:46 +0000

Добротно проорал с статьи:

Apple Computer Inc. plans to announce on Friday a software development and education project for Ukraine that is designed to take advantage of a labor force with high computer skills and low wages.

In a joint agreement with the National Academy of Sciences of Ukraine, Apple will train programmers, assign them basic programming and market Ukrainian software inventions abroad.

There are roughly 500,000 computer programmers among Ukraine’s 53 million citizens. Half of the country’s programmers are said to live in Kiev.

President Leonid M. Kravchuk endorsed the Apple project after a study predicted that Ukraine could capture 2 percent of the world’s software market and create 100,000 jobs within five years.

Apple will initially invest $30,000, according to the agreement, which was signed on Wednesday.

In return, Ukrainian programmers will write software for Apple at a quarter of the price that such work would cost in the West.

The Ukrainian subsidiary will also set aside 45 percent of its profits from the software exports marketed by Apple to purchase Apple hardware.

Ukraine!?

Vladimir Boychentsov — Tue, 09 Jun 2009 08:29:59 +0000

Что у нас за страна!? :( Все крупные компании нас обходят стороной, такие как: Apple, Google, …

Блин я просто в шоке! У Apple мы вообще числимся только в списках…

PayPal это вообще молчу… :(

Правительство у нас “идет в ногу со временем”!

Может устроить протест?
Что мы можем сделать, простые граждани нашей страны?
Может у кого-то есть свои идеи?

Я хоть и не заядлый патриот, но желания у меня пока нету выехать из страны чтоб пользоваться всеми услугами. Пользоваться под другими данными и достовать все по более приемлемым ценам через десять лиц, меня тоже не радует и порядном поднадоело :(

Буду ресерчить, может уже есть какие движухи?! Если кто из читателей знает отпишите пожалуйста! Если не найду возможно буду организовывать, чисто на общественных началах.

З.Ы.: Это было написано после просмотра WWDC 09, хоть и конференция меня и не впечатлила…
