Syntax Error in IOS - ios

I think its been very simple question, but i'm stuck to it quite long time. I have a function but getting some brackets issue and unable to run the code. I'm not getting where the brackets should close.
My code is,
-(void)Images{
NSString *eachImagePath;
if(_arrai.count == 0)
return;
eachImagePath = [NSString stringWithFormat:#"%#",_arrai[0]];
NSMutableDictionary *dictAddNewJobImages = [[NSMutableDictionary alloc]init];
dictAddNewJobImages[#"property_id"] = Propid;
dictAddNewJobImages[#"name"] = _arrainame;
NSString *strWebService = [NSString stringWithFormat:#"My URL"];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer.acceptableContentTypes=[NSSet setWithObject:#"text/html"];
[manager.requestSerializer setTimeoutInterval:600.0];
[manager POST:strWebService parameters:dictAddNewJobImages constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData)
{
NSURL *filePath = [NSURL fileURLWithPath:eachImagePath];
[formData appendPartWithFileURL:filePath name:#"image" error:nil];
} progress:^(NSProgress * _Nonnull uploadProgress)
{
} success:^(NSURLSessionDataTask* _Nonnull *task, id _Nullable responseObject)
{
NSLog(#"%#",responseObject);
[_arrai removeObjectAtIndex:0];
if(_arrai.count > 0)
[self Images];
} failure:^(NSURLSessionDataTask* _Nullable task, NSError* _Nonnull error) {
NSLog(#"%#",error);
}
}

you forget to close your block }];
use
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:XXXXXX parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}]; --> add the close in failure
instead of
[manager GET:XXXXXX parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}
updated answer
-(void)Images{
NSString *eachImagePath;
if(_arrai.count == 0)
return;
eachImagePath = [NSString stringWithFormat:#"%#",_arrai[0]];
NSMutableDictionary *dictAddNewJobImages = [[NSMutableDictionary alloc]init];

[self Images];

How to send image with parameter in AfNetworking

i am sending it with parameter but no working and in Postman Itis working see screenshot below

How to send image as parameters (param) with POST with AFNetworking

I need to send image as param like
URl : some API
params : {profileImage:string(file)}
Means in param list only i have to send image file as string.
i used the below code. but it is not working.
NSData *dataImage = [[NSData alloc] init];
dataImage = UIImagePNGRepresentation(selectedImage);
NSString *stringImage = [dataImage base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
NSDictionary *params = {profileImage : stringImage}
NSString *url = [NetworkRoutes postProfileImageAPIWithMobileNumber:[PTUserDetails getMobileNumber]];
self.operationManager = [AFHTTPSessionManager manager];
self.operationManager.responseSerializer = [AFJSONResponseSerializer serializer]; //
[self.operationManager.requestSerializer setAuthorizationHeaderFieldWithUsername:#“userName” password:#“some password”];
[self.operationManager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
NSError *error;
if (![formData appendPartWithFileURL:[NSURL fileURLWithPath:path] name:#"file" fileName:[path lastPathComponent] mimeType:#"image/jpg" error:&error]) {
NSLog(#"error appending part: %#", error);
}
} progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
your answer no need to be in afnetworking , can also be in nsurlconnection
I am getting resposne
{
response :"Please upload image file"
}
OR
Suggest me how to do like in the attached screen shot . In post man i am getting response
NSData *imgData = UIImageJPEGRepresentation(image, 1.0);
NSUInteger fileSize = [imgData length];
if(fileSize>400000)
{
float size = (float)((float)400000/(float)fileSize);
imgData = [NSData dataWithData:UIImageJPEGRepresentation(image, size)];
}
NSString *imgProfilePic = [imgData base64Encoding];
and then you can send this imgProfilePic to Webservice
If you send your image in multipart then this might be helpful and easiest way than BASE64
and also no need to convert your image into BASE64 String.
- (void)uploadImage:(UIImage*)image withParams:(NSDictionary*)paramsDict withURL:(NSString *)URL
{
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
AFHTTPRequestOperationManager *manager =
[AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:URL parameters:paramsDict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
if (imageData!=nil) {
[formData appendPartWithFileData:imageData name:#"imagename" fileName:#"filename" mimeType:#"image/jpeg"];
}
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"success = %#", responseObject);
[appDelegate dismissLoading];
if ([[responseObject valueForKey:#"code"] isEqualToString:#"200"])
{
// code after success
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[appDelegate dismissLoading];
NSLog(#"error = %#", error);
}];
}
Try to send like following (one of the below) way:
1.
-(void)uploadimage{
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://your server.url"]];
NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);
// if you want to pass another parameter with image then
NSDictionary *param = #{#"username": self.username, #"password" : self.password};
AFHTTPRequestOperation *operation = [manager POST:#"rest.of.url" parameters:param constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary, but append it!
[formData appendPartWithFileData:imageData name:paramNameForImage fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[operation start];
}
2.
UIImage *image = [UIImage imageNamed:#"imageName.png"];
NSData *imageData = UIImageJPEGRepresentation(image,1);
NSString *queryStringss = [NSString stringWithFormat:#"http://your server/uploadfile/"];
queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
[formData appendPartWithFileData:imageData name:#"fileName" fileName:#"imageName.png" mimeType:#"image/jpeg"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *dict = [responseObject objectForKey:#"Result"];
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];

How to Upload Multipart data of image in base64 Using afnetworking

I have used the following code but the response which i get is java.lang.NullPointerException & INTERNAL_SERVER_ERROR I tried many different methods but unable to fix it please help in fixing this.
Getting the Image from the Image picker
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
Profilebackground.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
NSURL *resourceURL;
UIImage *image =[[UIImage alloc] init];
image =[info objectForKey:#"UIImagePickerControllerOriginalImage"];
NSURL *imagePath = [info objectForKey:#"UIImagePickerControllerReferenceURL"];
imageName = [imagePath lastPathComponent];
resourceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
NSString *extensionOFImage =[imageName substringFromIndex:[imageName rangeOfString:#"."].location+1 ];
if ([extensionOFImage isEqualToString:#"JPG"])
{
imageData =UIImageJPEGRepresentation(image, 1.0);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=#"image/jpeg";
}
else
{
imageData = UIImagePNGRepresentation(image);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=#"image/png";
}
int imageSize=imageData.length/1024;
NSLog(#"imageSize--->%d", imageSize);
if (imageName!=nil) {
NSLog(#"imageName--->%#",imageName);
}
else
{
NSLog(#"no image name found");
}
Send the Image to server
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:#"https://blahblahblah.com/uploadProfileImg?userId=1" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//NSData *pngData = [[NSData alloc] initWithBase64EncodedString:base64 options:1];
[formData appendPartWithFileData:imageData
name:#"key"
fileName:imageName mimeType:extension];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSHTTPURLResponse *response = (NSHTTPURLResponse *)task.response;
NSLog(#"error: %#",error);
// NSHTTPURLResponse *response = (NSHTTPURLResponse *)operation.response;
NSLog(#"statusCode: %ld", (long)response.statusCode);
NSString* ErrorResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(#"Error Response:%#",ErrorResponse);
}];
You can just use the appendPartWithFileData:name:fileName:mimeType: method of the AFMultipartFormData class.
For instance:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager POST:#"https://blahblahblah.com/imageupload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:#"key name for the image"
fileName:photoName mimeType:#"image/jpeg"];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: %#", error);
}];
Please try the below code in AFNetworking 2.0.3
Hope this will helpful for u
- (void) createNewAccount:(NSString *)nickname accountType:(NSInteger)accountType primaryPhoto:(UIImage *)primaryPhoto
{
// Ensure none of the params are nil, otherwise it'll mess up our dictionary
if (!nickname) nickname = #"";
NSLog(#"Creating new account %#", params);
[self POST:#"accounts" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFormData:[nickname dataUsingEncoding:NSUTF8StringEncoding] name:#"nickname"];
[formData appendPartWithFormData:[NSData dataWithBytes:&accountType length:sizeof(accountType)] name:#"type"];
if (self.accessToken)
[formData appendPartWithFormData:[self.accessToken dataUsingEncoding:NSUTF8StringEncoding] name:#"access_token"];
if (primaryPhoto) {
[formData appendPartWithFileData:UIImageJPEGRepresentation(primaryPhoto, 1.0)
name:#"primary_photo"
fileName:#"image.jpg"
mimeType:#"image/jpeg"];
}
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Created new account successfully");
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: couldn't create new account: %#", error);
}];
}
At last I made it work
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:#"https://blahblahblah.com/uploadProfileImg?userId=1" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:#"key"
fileName:imageName mimeType:extension];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSHTTPURLResponse *response = (NSHTTPURLResponse *)task.response;
NSLog(#"error: %#",error);
NSLog(#"statusCode: %ld", (long)response.statusCode);
NSString* ErrorResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(#"Error Response:%#",ErrorResponse);
}];

Always got nil value from the function in iOS

I'm using AFNetworking for some GET queries. But my function always returns nil value. Where I was wrong?
+ (NSString *)getRequestFromUrl:(NSString *)requestUrl {
NSString * completeRequestUrl = [NSString stringWithFormat:#"%#%#", BASE_URL, requestUrl];
__block NSString * results;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:completeRequestUrl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
results = [NSString stringWithFormat:#"%#", responseObject];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
results = [NSString stringWithFormat:#"Error"];
}];
NSLog(#"%#", results);
return results;
}
Thx! Artem.
You're not seeing a result because the blocks that you pass in for success and failure run asynchronously; by the time your NSLog gets called, the web service won't have returned yet. If you move your NSLog inside of your success and failure blocks, you should see a result get output to your console.
Because of the asynchronous nature of these calls, you won't be able to simply return the value from your method. Instead, you may want to take your own block as a parameter, which you can then call when you have a result. For example:
+ (void)getRequestFromUrl:(NSString *)requestUrl withCompletion:((void (^)(NSString *result))completion
{
NSString * completeRequestUrl = [NSString stringWithFormat:#"%#%#", BASE_URL, requestUrl];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:completeRequestUrl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *results = [NSString stringWithFormat:#"%#", responseObject];
if (completion)
completion(results);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSString *results = [NSString stringWithFormat:#"Error"];
if (completion)
completion(results);
}];
}
You would then call your method like so:
[YourClass getRequestFromUrl:#"http://www.example.com" withCompletion:^(NSString *results){
NSLog(#"Results: %#", results);
}
AFNetworking's sample project has an example of using a block parameter to return a value from your web service calls: https://github.com/AFNetworking/AFNetworking/blob/master/Example/Classes/Models/Post.m
- (void)POST:(NSString *)URLString
parameters:(id)parameters
constructingBodyWithBlock:(void (^)(id <AFMultipartFormData> formData))block
progress:(nullable void (^)(NSProgress * _Nonnull))uploadProgress
success:(void (^)(NSURLSessionDataTask *task, id responseObject))success
failure:(void (^)(NSURLSessionDataTask *task, NSError *error))failure
{
[_manager POST:[NSString stringWithFormat:#"%#%#",API_HOST,URLString] parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
block(formData);
} progress:^(NSProgress * _Nonnull uploadProgress1) {
uploadProgress(uploadProgress1);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
success(task,responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
failure(task,error);
}];
}
