This is a guide to help developers get up to speed with AFNetworking. It is geared primarily towards anyone who is new to Mac or iOS development, or has not worked extensively with 3rd-party libraries before.
These step-by-step instructions are written for Xcode 5, using the iOS 7 SDK. If you are using a previous version of Xcode, you may want to update before starting.
Instead of boasting an killing your time over waste info, this tutorial will now direct you to implementation in simple easy steps. Enjoy saving your time to impress your managers.
1. Download the AFNetworking Library from this Link:
2. Drag and Drop the entire folder "AFNetworking" in your project.
Files: 1. AFURLRequestSerialization.m
2. AFNetworkReachabilityManager.m
3. AFNetworkActivityIndicatorManager.m
4. AFHTTPRequestOperation.m
5. AFHTTPSessionManager.m
6. AFHTTPRequestOperationManager.m
7. AFSecurityPolicy.m
8. AFURLResponseSerialization.m
4. Import this in your project's .pch file .
#import "AFNetworking.h"
Tag: http://icodesforcrazyclients.blogspot.in/2015/11/how-to-add-pch-file.html
5. Import Security Framework.
6. This was all about background settings. But we have not yet covered how to use it as methods to operate on web services , i.e. to send the parameters to associated web services and response handling.
Below are the methods you just need to copy and use.
6.1 Create a class of NSObject and give it a name say "AFNetworkMethods"
6.2 Add these method declaration in its .h file:
6.3.1 POST METHOD
+(void)callPostWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter success:(void(^)(id response))successBlock errorBlock:(void(^)(NSError *error))errorBlock;
6.3.2 GET METHOD
+(void)callGetWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter Block:(downloadBlock)block;
+(void)callPutWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter success:(void(^)(id response))successBlock errorBlock:(void(^)(NSError *error))errorBlock;
and add this statement after the header file of .h file:
typedef void(^downloadBlock)(id success,NSError *error);
6.3 Now we will define the methods in its .m file:
First import app delegate in .m file:
#import "AppDelegate.h"
6.4
6.4.1 POST METHOD
+(void)callPostWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter success:(void(^)(id response))successBlock errorBlock:(void(^)(NSError *error))errorBlock
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:urlString parameters:parameter success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSError *error;
id result = [NSJSONSerialization JSONObjectWithData: responseObject options: NSJSONReadingMutableContainers error:&error];
successBlock(result);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
//NSLog(@"%@",[error description]);
errorBlock(error);
}];
}
6.4.2 GET METHOD
+(void)callGetWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter Block:(downloadBlock)block;
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"text/html"];
NSString *token=[[NSUserDefaults standardUserDefaults] objectForKey:@"TOKEN"];
NSString *str=[NSString stringWithFormat:@"Token %@",token];
[manager.requestSerializer setValue:str forHTTPHeaderField:@"Authorization"];
AFJSONResponseSerializer *jsonReponseSerializer = [AFJSONResponseSerializer serializer];
jsonReponseSerializer.acceptableContentTypes = nil;
manager.responseSerializer = jsonReponseSerializer;
[manager GET:urlString parameters:parameter success:^(AFHTTPRequestOperation *operation, id responseObject)
{
block(responseObject,nil);
}failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
block(nil,error);
}];
}
+(void)callPutWSWithMethod:(NSString*)methodName withUrl:(NSString*)urlString withParameter:(NSDictionary*)parameter success:(void(^)(id response))successBlock errorBlock:(void(^)(NSError *error))errorBlock
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer=[AFHTTPResponseSerializer serializer];
NSString *token=[[NSUserDefaults standardUserDefaults] objectForKey:@"TOKEN"];
NSString *str=[NSString stringWithFormat:@"Token %@",token];
[manager.requestSerializer setValue:str forHTTPHeaderField:@"Authorization"];
[manager PUT:urlString parameters:parameter success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSError *error;
id result = [NSJSONSerialization JSONObjectWithData: responseObject options: NSJSONReadingMutableContainers error:&error];
successBlock(result);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
errorBlock(error);
}];
}
7. Now we are all set to use these methods. lets see how to implement these methods. One thing that we need to know before implementing the last stage is that AFNetworking runs on a different thread,So you may find difficulty in handling them. But i know Visitors are smart enough to handle them. But why to waste time ,lets fasten the process of development and just copy and paste even this where you want to call the web service.
7.1 METHOD ILLUSTRATION
-(void) YourMethodName
{
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];
// add parameters to the dictionary.
[AFNetworkHelper callPostWSWithMethod:@"" withUrl:
@"your web service url " withParameter:parameters success:^(id response)
{
if((response == nil) || (response == NULL))
{
return;
}
if(response)
{
// Handle the response.
}
else
{
return;
}
}
errorBlock:^(NSError *error)
{
NSLog(@"%@",error);
}];
}
Hope you will not find any difficulty implementing AFNetworking.
