POST image to PHP web service in IOS - ios

Question

I have made some image views and their button under them. When user select image from gallery it displays on image view. Now I want that image to be sent to server through PHP web service and use POST method. I want it to first convert it to base64 bits.
My code is
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"ddMMyyyyHHmmss"];
NSData *data = UIImageJPEGRepresentation(_img1.image, 1.0);
UIImage *imagedata = [UIImage imageWithData:data];
NSString * base64String = [data base64EncodedStringWithOptions:0];
NSDate *now = [[NSDate alloc] init];
NSString *theDate = [dateFormat stringFromDate:now];
//---------- Compress photo----------
double compressionRatio = 1;
int resizeAttempts = 5;
while ([data length] > 1000 && resizeAttempts > 0)
{
resizeAttempts -= 1;
compressionRatio = compressionRatio*0.6;
data = UIImageJPEGRepresentation(imagedata,compressionRatio);
}
NSString *baseurl = #"myurl";
NSURL *dataURL = [NSURL URLWithString:baseurl];
NSMutableURLRequest *dataRqst = [NSMutableURLRequest requestWithURL:dataURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:500.0];
[dataRqst setHTTPMethod:#"POST"];
NSString *stringBoundary = #"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo";
NSString *headerBoundary = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",stringBoundary];
[dataRqst addValue:headerBoundary forHTTPHeaderField:#"Content-Type"];
NSMutableData *postBody = [NSMutableData data];
// -------------------- ---- image Upload Status -----------------------
[postBody appendData:[[NSString stringWithFormat:#"--%#\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"image\"; filename=\"%#\"\r\n",[NSString stringWithFormat:#"%#.jpeg",theDate]] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[#"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:data];
[postBody appendData:[#"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"--%#--\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[dataRqst setHTTPBody:postBody];
self.conn = [[NSURLConnection alloc] initWithRequest:dataRqst delegate:self];
//SubmitDetailsViewController *presales = [self.storyboard instantiateViewControllerWithIdentifier:#"SubmitDetailsViewController"];
// [self.navigationController pushViewController:presales animated:YES];
}
#pragma mark NSURLConnection Delegate Methods
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
self->recieveData = [[NSMutableData alloc] init];
}
//------------- Response from server -------------
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[ self->recieveData appendData:data];
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&error];
}

You can use AFNetworking library to do this. Add AFNetworking to your projec and import AFNetworking.h in to your class and you can then do something like,
UIImageView *imageView; // your image view
NSData *imgData = UIImageJPEGRepresentation(imageView.image, 1.0);
NSString *base64ImageStr = [imgData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
NSString *strToSend = [base64ImageStr stringByReplacingOccurrencesOfString:#"+" withString:#"%2B"];
NSDictionary *parameters = #{#"yourServerKeyOrParameterForImage" : strToSend}; // you can add other parameters as well
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[[manager POST:#"your url" parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(#"your response : %#",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"error : %#",error.localizedDescription);
}]resume];
