First, open XCode4.6.3, new projectIi. Select the named line item under ApplicationThird, enter the project name, select the foundation framework to create the project, click NextFour, apart, click Run, start the project we createdYou can see the results of the output:OK, the first OC app is created! Next explain the following main.m:1, #import是一个导入命令, similar to the C language of the # include command, but relative to # include, #import有效的处理了重复导入的问题,

The previous article introduced the use of the @class keyword in oc http://blog.csdn.net/jiangwei0910410003/article/details/41774747, which we introduce, A unique highlight in OC: CategoryFirst, let's take a look at the scenario, what should we do if we want to expand the functionality of a class now?For object-oriented programming, inheritance is first thought, but there are two problems with inheritance:T

OC and Swift are 2 in different languages, OC code can only be written with OC files, Swift code can only be written in Swift file, although 2 different languages, but can call each other, but need to do a bridge, is the following 2 files(Projectnmae-bridging-header.h)Swift file to invoke OC code you will find that you

so, execute the query command JS and refresh the message queue, if all do not match, the URL is recognized as unknown message.2, the use of WebviewjavascriptbridgeFirst of all, to access the framework in JS, this code is unchanged /** * This is the function of the JS access frame * /function Setupwebviewjavascriptbridge (callback) { if (window.

The first OC Program source code is as follows:#import int main (intconstChar * Argv[]) { @autoreleasepool { NSLog (@ "hello,world!

1. How to write a class declarationStart with @interface , end with @end , and then write the name of the object in the same place as the class name.Note: The first character of the class name must be capitalizedThe purpose of declaring a class is to tell the system what properties and behaviors we have in this classThe properties in the OC class declaration can only be in {} between write @interface and @endNote: When writing

As we all know, a macro definition is a compile-time constant. And OC is a dynamic language.Two macro definitions for 1.iOS system version1 __iphone_os_version_max_allowed //iOS system version maximum allowed 2 //iOS system version minimum requiredUsing these two macros will only eliminate the compiler's warning. Because OC is a dynamic language, the system version also needs to be judged. For example:2.

1. Why do I need nsstring objectsA: When you create a string in OC, you generally do not use the C method.Because C takes a string as an array of characters, there are many inconvenient things to do in the operation.Some methods of nsstring integration in cocoa can easily manipulate strings,Comparison of strings and C strings in 2.oc"Hello World"@ "Hello World"1) Output Mode%@2) Citation methodNSString begi
