between processes is already high. for more information, seeDistributed Objects Programming Topics. Design Skills 1. Avoid explicit thread Creation It is boring to manually write the thread to create code and it is prone to errors. You should avoid doing so as much as possible. Mac OS X and iOS provide implicit concurrency support through other API interfaces. You can consider using asynchronous APIs, GCD

IOS UI programming-Implementation of neon lights, iosui-neon lights I have been studying UI programming for three or four days. I have learned some basic views and controls over the past few days, such as UIView, UIlabel, and UIButton ., to learn about UI programming, you can see the effect by writing your own code. Th

IOS Programming Dynamic Type 2, iosprogramming IOS Programming Dynamic Type 2 You will need to update two parts of this view controller for Dynamic Type: the rows of your table view will grow or shrink in response to the user changing the preferred text size, and the BNRItemCell will need to be updated similarly to how

iOS several major programming ideasObject oriented thought: All things are objects, the process of doing one thing turns into the process of object handling event.Chained programming idea: to pass multiple operations through a point (.) Linking together becomes a code that makes the code read better. For example P.add (1). Add (2). The special place is that each

This article focuses onIOSOfMulti-core programmingAndMemoryManagement, why? Because iPad 2 is already a dual-core CPU! Although the iPad 1 application is no longer slow, you can use Apple'sMulti-core programmingFramework to write more responsive applications. Multi-core operations InIOSIn concurrency programming framework is GCD (Grand Central Dispatch), GCD is very simple to use. It distributes tasks to different queueQueue. The developer installs th

1. "Power-saving, smooth, high-quality application, fast response, good user experience ..." may be the apple system in the eyes of many users.2. The iphone user experience is still strong, as Apple continues to stick to dual-core in the era of CPU frequency, 4-core, 8-core.The above two points iOS is how to optimize, in the endurance, smoothness and response speed of the victory over Android, the answer is multithreaded runloop ...Runloop is the core

First, build the environment.It's really annoying that iOS programs have to be programmed on Mac OS X systems. This is not the intention to pit me such a poor person ...It took almost an afternoon to finally find the available Mac OS X 10.9 system, the VMware Patch () and the System Installation graphics tutorial (search it yourself).Then the installation of the bitter force ....Ii. A preliminary study of XcodeFinally run the Mac OS X system, the hear

by the value, Instead, we give the value . when we actually execute the block, so for the number of referencesblock, when we pass the past, it needs the receiver to provide the corresponding parameters of the ability to execute, so we can do the merit of the Class A for the future events of Class B, even if we don't have the detailed arguments of these events . In a sense it would not be necessary to entrust the relationship between the two . the trust relationship is a Class B after an event,
