Custom class implementation Objective: To customize a Person class and implement copy. First, define a Person class. Because it is a custom class, to support the copy method, you need to implement the @interface Person : NSObject @ Implementation Person-(id) copyWithZone :( NSZone *) zone {id p = [[self class] allocWithZone: zone] init]; Test in main. m file Person * p1 = [[Person alloc] init]; // create the p1 object [p1 setName: @ "Michael" sex: @ "male"]; // assign the Person * p2 = [p1 c

This status code can be exchanged with 301 sometimes. For example, if you mistakenly access http: // host /~ If the path information is incomplete, some servers will return the 301 status code, and some will return the 302 status code. Technically, if the initial request is a get browser, it is assumed that the browser i

In the previous article, we have explained the first three methods for creating nsstring. Now we are talking about the other three methods. These three methods are also calledCreate temporary string. The three methods are as follows: Stringwithuf8string:Converts a C-type string to an OC string, which is similar to the initwithuf8string mentioned earlier. However, alloc is not used to create a C-type string. Stringwithformat:Return an initialized string and some custom parameters to the

How to Use enumerated Arrays: This involves an enumeration method, nsenumerator, which indicates that we should know what it is. If we do not know it, please check related videos or materials by yourself. To create an array using the enumeration method, first create an immutable array with array elements. Then, the elements in the array are printed one by one using the enumeration method. The following is a detailed example: #import The output result is as follows: 2014-10-12 1

Session tracking is discussed in chapter 9 and the habit of using encodeURL makes it much easier to add session tracking later.

browser can automatically access the new URL, so it is a useful status code. Note that this status code can sometimes be used with 301 substitutions. For example, if the browser mistakenly requests Http://host/~user (the trailing slash is missing), some servers return 301, and some return 302. Strictly speaking, we can only assume that the browser will automatically redirect only if the original request is get. See 307. 303-see other is similar
