And paste a small tempered film, you can give your phone a layer of protection, if dropped on the ground, the damage is only a layer of tempered film, a

After iOS4.1, the ARC mode is the default, and arc is essentially implemented with compiler features, which can be implemented simply by modifying the file configuration.1. To switch to MRC you need to select the current project, choose Build Settings, type Auto in the query box, find Objective-c Automatic Reference counting, and select Yes to No. See:2. You can also flexibly select single or several files

used to define block variables in the future. MyBlock a,b; a=^(int a,int b){return a-b;};MyBlock b2=^(int n1,int n2){return n1*n2;};Iv. Introduction to arc1.arc ARC is a new feature added since ios5, which completely eliminates the hassle of manual memory management. The compiler will automatically insert appropriate retain, release, and autorelease statements in appropriate places. You no longer need to

Today, a BUG broke out in the company, leading to 5000+crash. Roughly, the delegate in UIKit visited the already released interface, which is the use of wild pointers to cause crash. Come back and demonstrate the discovery @property (nonatomic, assign) id Most of the UIKit's delegate are statements like 1. Because iOS doesn't have ARC before 5, it's written assign for compatibility. So what's the difference between assign and weak? __strong nsstring *

IOS5 added new knowledge, that is, arc, in fact, I do not really like it, because I used to manage the memory. But learning is still necessary.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.Now let's look at the New keyword in iOS5 strong, weak, unsafe_unretained. can be corresponding to

Android arc ListView implementation, androidlistview This article will show you how to arrange the Arc Distribution of ListView. The principle is very simple, that is, to offset each Item based on the height of each item in ListView. First, define a LinearLayout. This is the root layout of each Item in ListView, which is used to offset each item. The code below: Public class MatrixLinearLayout extends Line

Single-Case mode:1. Always allocate only one piece of memory to create objects2. Provide a class method that returns an internally unique object (one instance)3. It is best to ensure that the Init method is initialized only onceThe general wording of the arc under the single example (\ In the code is the definition of the macro):Static ID_instance;+ (ID) Allocwithzone: (struct_nszone *) zone{Staticdispatch_once_t Oncetoken; Dispatch_once (oncetoken, ^

Before using the attribute keyword, you need to understand the role of the property keyword. In fact, "simply speaking ..." is to guide the bottom how to generate set, get method, if you do not define the set, get method, the system will be automatically generated for you, but how to generate based on these property keywords, the combination of different property keywords will determine the set, get method specific implementation, The realization is different, the function naturally also is diff
