How to get response from static library in ios - ios

Question

In my application I am using one static library. In that library I implemented code for establish a connection with the server. For server interaction I used NSURLSession but it's delaying the UI response to avoid it I have started using NSURLConnection delegate methods now I am getting the response from server but here I don't know how to send the response back to actual code from did finish loading method.
In my team I want to distribute this library to both iphone and ipad development engineers. They don't have any control on server related code everything I implemented in static library. So please show me the solution for my problem thanks in advance.
The below is the code which I used in one class of static library:
StaticClass:
.h File
#interface StaticClass : NSObject<NSURLConnectionDelegate,NSURLSessionDelegate>
{
NSMutableDictionary *responseDictionary;
NSUserDefaults *serviceURlInUserDefaults;
NSData *responseData;
}
#property (nonatomic, weak) id <DataReciverDelegate>delegate;
#property(strong,nonatomic)NSData *responseData;
-(void)loginWithUsername:(NSString *)name password:(NSString*)password serviceUrl:(NSString*)serviceUrl domainName:(NSString*)domainName ;
#end
import "StaticClass.h"
#protocol DataReciverDelegate <NSObject>
#required
- (void)responseDictionary:(NSDictionary *)response;
#end
#implementation StaticClass
#synthesize responseData;
-(void)loginWithUsername:(NSString *)name password:(NSString*)password serviceUrl:(NSString*)serviceUrl domainName:(NSString*)domainName
{
NSString *ApiStr=[NSString stringWithFormat:#“http://login.com”];
NSURL *Url=[[NSURL alloc]initWithString:[loginApiStr stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
NSURLRequest *ApiRequest=[NSURLRequest requestWithURL:loginUrl];
NSURLConnection *connection=[[NSURLConnection alloc]initWithRequest:ApiRequest delegate:self];
[connection start];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
self.responseData=data;
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
responseDictionary=[NSJSONSerialization JSONObjectWithData:self.responseData options:0 error:nil];
[_delegate responseDictionary:responseDictionary];
}
#end
Response where I want to use is in class1 :
Here please let me know how can i include that delegate which i created in static library class
#interface Class1 : NSObject<NSURLConnectionDelegate,NSURLSessionDelegate>
{
}
#end
#implementation Class1
-(void)login
{
StaticClass *object1=[[StaticClass alloc]init];
[object loginWithUsername:#“AAA” password:#“BBB” serviceUrl:url domainName:dname];
}

Answer 1

You can either offer API to notify that response has been read from the connection, or you can send a notification.
The first can be accomplished by either implementing a delegate protocol and setting the delegate in the using app, or by using block-based API, where the using app would set a block to handle events. You see these two patterns very often in system-provided API, including NSUrlConnection.
Another option is to use notifications. You register for a particular notification name in the using app, and in the lib you post once your connection returns data.

Answer 2

You need to implement a protocol in your static library like:
#protocol DataReciverDelegate <NSObject>
#required
- (void)dataReceived:(NSData *)data;
#end
Also declare a property there like:
#property (nonatomic, weak) id <DataReciverDelegate>delegate;
In your static library implementation, implement the connectionDidFinishLoading like:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[_delegate dataReceived:_dataYouReceived];
}
Now you need to implement the DataReciverDelegate in the class you need to get the data, and When you create the object of your static library class, set the delegate.
