[IOS learning basics] weak and strong, lazy loading, cyclic reference, and iosweakI. weak and strong 1. Understanding When I first started to learn the UI, the description of weak and strong was most often described as "introduced by ARC. weak is equivalent to assign in OC, but weak is used to modify objects, however, they do not add 1 to the reference count, whi

The first sentence summed up: Strong class to keep their own objects alive, weak class They have the object of a adaptation led by someone else, was worked to die. (Strong is a good eldest brother so strong, hehe, weak is a virtual eldest brother so weak, hehe)For example, one object is a string class, and the instance is @ "Hello"The existing two

Arc Declaration Property keyword in detail (strong,weak,unsafe_unretained,copy)In the development process of iOS, the definition of attributes is often related to retain, assign, copy, I think we are very familiar with this, I do not introduce, there are many related articles on the Internet.But adding arc to iOS 5 produced several new keywords strong, weak, unsafe_unretained. We can learn from the previous

Strong naming can make assembly unique (even if the name is the same), so that the program loads assembly is a trusted assembly, but strong naming can only be applied to. NET Framework managed code, so Microsoft has another Authenticode signature, It can be applied to managed and unmanaged code. Strong name has two points to note 1. If the assembly needs to be in

ARCThe compile time feature of the automatic memory management of the ARC Apple version. It represents the automatic reference count (Automatic Reference counting). That is, for an object, memory is freed only if the reference count is 0.Strong (strong reference)Let's start with what is a strong quote. It is essentially a generic reference (pointer, and so on), b

Objective-c, the strong and weak pointers under ARC are explained in principleTip: The "instance variable" in this article is "member variable" and "local variable" isFirst, IntroductionARC is a new feature that has been added since iOS 5, completely eliminating the cumbersome manual management of memory, and the compiler will automatically insert the appropriate retain, release, and autorelease statements where appropriate. You no longer need to worr

What is the error "no strong name" during debugging?-------------------------------------------------------------------------------- I have now written a testProgramProcess:Dataaccess. a aa = new dataaccess. ();Dataaccess is a class library.A is the classThis error occurs during compilation.Error exampleThank you! -------------------------------------------------------------------------------- A strong

In the case of MRC during iOS development, attribute definitions are often related to retain, assign, and copy. The New Keyword strong, weak, unsafe_unretained in ios5. it can be similar to learning strong and retain corresponding to previous keywords. Weak and unsafe_unretained functions are similar (a little different. We will introduce them later. These two new keywords are similar to assign ). With thes

Strong decorated properties are strong pointer types, and weak decorated properties are weak pointer types.Arc for an in-memory object management mechanism, when an object is not pointed to by a strong pointer, the object will be destroyed.So inappropriate use of strong and weak modifiers can easily cause memory leaks.

A person with a strong heart is a truly thoughtful person. Xu xiliang My friend, Professor of South China Normal University, and Dr. Liu Lianghua, a talented and talented young talent, once said:Famous saying: A person with strong prejudices is a real thinker. This sentence has a wide influence among his students. If you think of "strong prejudice" as a means

The Java 2 platform introduces the java. Lang. Ref package, including classes that allow you to reference objects without leaving them in memory. These classes also provide limited interaction with the garbage collector. Peter Haggar analyzes functions and behaviors of softreference, weakreference, and phantomreference classes in this article, and provides some suggestions on the programming style for the use of these classes.When the java. Lang. Ref package (including softreference, weakreferen
