ios中Web服务的单例类

我是iOS新手，在开发过程中，我随时随地都在调用web服务……我想要一个用于get、post、put方法的类……然后调用[self post]； [参数：…]。。。这意味着我想为所有get服务和post调用单个方法。。请帮帮我……怎么样

NSURL *url = [NSURL URLWithString:@"https://example.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        height, @"user[height]",
                        weight, @"user[weight]",
                        nil];
[httpClient postPath:@"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"Request Successful, response '%@'", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];

For AFNetworking 2.0 (and also using the new NSDictionary syntax):

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

从这里可以创建singleton类-

然后，您需要使用完成处理程序创建自己的方法，并在需要的地方调用

示例：Post方法：

+(void)postWebserviceWithURL:(NSString*)webServiceURL withParam:(NSDictionary*)urlParameters withCompletion:(void(^)(NSDictionary*response))completion {
//Your code goes here
}

---

下面是相关的答案。您应该创建类似webservices的nsobject类，并像这样创建singleton实例对象

+(WebServices *)sharedInstance{

    /* Use this to make it a singleton class */
    if (sharedObj==Nil) {
        sharedObj=[[WebServices alloc]init];
    }
    return sharedObj;
     /**/
}

使用这个单例实例，您可以根据需要调用这些方法

Eg: [[webservices sharedInstance] post];

使用该方法，您可以使用所需的web服务点击，如post、get和put

使用Nsnotifiers使用API命中的响应

+ (instancetype)sharedInstance
{
static CustomClass *sharedInstance = nil;
static dispatch_once_t onceToken;

dispatch_once(&onceToken, ^{

//Override your constructor for custom initialization if you want
    sharedInstance = [[CustomClass alloc] init];
});

return sharedInstance;
}

然后定义CRUD操作的方法

简单地访问

[[CustomClass sharedInstance] POST:...];
[[CustomClass sharedInstance] GET:...];
