I am using AFNetworking classes to interact with web-service.I am having some problem in that.
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:theRequest];// using AFHTTPRequestOperation to request Data
[operation setRedirectResponseBlock:^NSURLRequest *(NSURLConnection *connection, NSURLRequest *request, NSURLResponse *redirectResponse) {
NSLog(@"connection :%@",connection);
NSLog(@"request :%@",request);
NSLog(@"response :%@",redirectResponse); question 1:? i get NSURLResponse value is null. output:response :(null)
return request;
}];
With the help of Breakpoint i check inside the AFNetworking classes (class name : AFURLConnectionOperation.m) whether it getting response from server? Yes its getting response.
- (void)setRedirectResponseBlock:(NSURLRequest * (^)(NSURLConnection *connection, NSURLRequest *request, NSURLResponse *redirectResponse))block {
self.redirectResponse = block;
NSLog(@"connection :%@",_connection);
NSLog(@"request :%@",_request);
NSLog(@"response :%@",_redirectResponse);//getting NSURLResponse from server.(its showing response) output: response :<__NSGlobalBlock__: 0x46238>
NSLog(@"block :%@",block);
}
My Problem is that when i call [operation setRedirectResponseBlock.....] inside my class NSURLResponse *redirectResponse always have null value but when i check in - (void)setRedirectResponseBlock..... inside the AFURLConnectionOperation.m class NSURLResponse *redirectResponse have some value. Can you Please Help to know that where i am wrong. last one week all days i was googling i couldn't find any answer that related to this.
i am using "theRequest.cachePolicy = NSURLRequestUseProtocolCachePolicy;" because i don't want to load all the time from server only if there any modification in header then only i want to call again. for this i need to use "setRedirectResponseBlock" to write below code.
if ([response isKindOfClass:[NSHTTPURLResponse self]]) {
NSDictionary *headers = [(NSHTTPURLResponse *)response allHeaderFields];
NSString *modified = [headers objectForKey:@"Last-Modified"];
if (modified) { .......
Please Help me to solve this, examples much appreciated.
