OC learning --- KVC and KVO operations, oc --- kvckvo In the previous article, we introduced the most common file operations in OC: commit. 1. KVC operations The KVC operation in OC is very violent with the variable that uses the reflection mechanism to remove the private permission of the classes in Java. This will d

The first OC program, the first oc Import is an upgraded version of include. import can automatically prevent repeated inclusion. Therefore, you should note that import is used when introducing header files. Foundation is a framework, and Foundation. h is the header file of the Foundation framework. The entry of the Oc program is the same as that of the C lang

OC learning --- array object reference counting and automatic release pool concept, oc Array In the previous article, we introduced the use of the two keywords @ property and @ synthesize in OC: Http://blog.csdn.net/jiangwei0910410003/article/details/41925967 Today, let's take a look at how array objects in OC handle t

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning

HTML code:"Content-type"Content="text/html; Charset=utf-8">[removed] function openalbum () {//Open the album (Openmyalbum is the method in OC)[REMOVED].HREF ='Ios://openmyalbum'; } function Opencamera () {//turn on the camera (Openmycamera is the method in OC)[REMOVED].HREF ='Ios://openmycamera'; } [removed]"Button"Value="turn on the camera"> "Button"Value="Open Album">

Use: In iOS development, often back to JS call OC code, such as on the webpage has a photo and call button, want to open the system comes with the camera and phone, you need to use JS call OC code function.Implementation principle: When the WebView load HTML page, not when send a request, will call the -(BOOL) WebView: (UIWebView *) WebView shouldstartloadwithrequest: (nsurlrequest *) Request Navigationtype

Array in Oc, Oc Array ====================================== Array ====================================== I. Recognize Arrays In oc, NSObject object subclasses can be placed in the array collection, but basic data types such as int, float, and double must be converted before they can be saved to the array. Arrays in oc

OC learning --- class extension, oc --- Extension In the previous article, we introduced the concept and usage of category: Category To put it bluntly, extension is to make up forForward DeclarationWe know that in C, if you want to call a function, you must declare a function before that, which is frontend. In OC, in order to make up for this problem in C languag

Enumeration used in OC development and enumeration in oc Definition of a common enumeration: typedef enum{LOGIN_SUCCESS,USER_NAME,USER_PASSWORD,OLD_LAT,OLD_LNG}FIELD_SAVED; 2. After iOS6 and Mac OS 10.8, Apple introduced two macros to redefine the two enumeration types. In fact, the enum definition and typedef are combined into one, different macros are used to distinguish them from the code perspective.

Therefore, in the actual development, in order to facilitate, will often customize the construction method.Next, customize a constructor metho

OC learning --- proxy mode, oc --- proxy In the previous article, we introduced the concept of the Protocol in OC: Protocol. Here is a simple example: Children, nurses, and nannies. There are two methods for children: wash and play. Here, the proxy objects are nurses, nannies, and children. Take a look at the Code: First, let's take a look at the Child class: Chi

capacity.3, allocated from the heap, also known as dynamic memory allocation. The lifetime of dynamic memory is determined by the programmer and is very flexible to use, but if space is allocated on the heap, it is the responsibility to reclaim it, otherwise the running program will have a memory leak, and frequently allocating and releasing different sizes of heap space will result in heap fragments.Second, OC Memory management (iOS7.0 after the man

OC language-memory management, oc-memory management 1. Introduction to memory management principles Memory Management for 1.1C Char * p = (char *) malloc (100 * sizeof (char )); This is the dynamic memory allocation of C. We manually applied for 100 bytes of memory with the system; or the system opened up 100 bytes of space in the heap, return the first address of the space to the pointer Variable p. Strc

OC Framework OC Language is an object-oriented language, similar to the Java, C #, C + + languages we normally touch. They are all composed of objects and methods. She and the process-oriented C language is very different, C language is the algorithm and data structure, there are a lot of differences between them, but their direct there are many similarities. For example, the basic objects and methods of th
