Appending image in collectionView using AFNetworking - ios

Question

I am new for Ios app development. I am using AFNetworking for image and data load, data are binned in collection view but unable to bind image.
This is my code for collection view and service:
#import "ViewController.h"
#import "LabelCollectionViewCell.h"
#interface ViewController ()
{
NSMutableArray *idArray;
NSMutableArray *namelabelArray;
UIImage *imagArray;
NSMutableArray *dic ;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[[self userCollection]setDataSource:self];
[[self userCollection]setDelegate:self];
[self dataJson];
NSLog(#"array: %#", namelabelArray);
}
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
return 1;
}
-(NSInteger) collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return [namelabelArray count];
}
-(UICollectionViewCell *) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
LabelCollectionViewCell *customCell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
[[customCell nameLabel]setText:[namelabelArray objectAtIndex:indexPath.item]];
[[customCell idLabel]setText:[idArray objectAtIndex:indexPath.item]];
return customCell;
}
-(void)dataJson
{
NSString *zipcode;
NSString *url = [NSString stringWithFormat:#"%#",#"http://inveera.biz/lowkall_api/index.php/product_cat"];
NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys: zipcode,#"35005",nil];
NSLog(#"Login URL %#", params);
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Login JSON: %#", responseObject);
NSString *data = [responseObject valueForKey:#"data"];
idArray = [data valueForKey:#"id"];
namelabelArray =[data valueForKey:#"name"];
imagArray =[data valueForKey:#"img_path"];
NSLog(#"Error image: %#", imagArray);
[self.userCollection reloadData];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
}
My json response is
{
"status":"true",
"city":[{"cityname":"Acmar"}],
"data":[
{"id":"1","name":"Appliances","img_path":"categories\/1\/ac1.png","status":"1"},
{"id":"2","name":"Electronics","img_path":"categories\/2\/ac2.png","status":"1"},
{"id":"3","name":"Furniture","img_path":"categories\/3\/ac3.png","status":"1"},
{"id":"4","name":"Cars","img_path":"categories\/4\/ac4.png","status":"1"},
{"id":"5","name":"Pet Supplies","img_path":"categories\/5\/ac5.png","status":"1"},
{"id":"6","name":"Others","img_path":"categories\/6\/ac6.png","status":"1"}
]
}
I am able to bind name but unable to bind image with full path with domain
name.
Please help me out. Thanks in advance.

In AFNetworking Lib itself they have added one category class for UIImageView called UIImageView+AFNetworking to load images from URL, You need call below method with valid URL request.
- (void)setImageWithURLRequest:(NSURLRequest *)urlRequest
placeholderImage:(UIImage *)placeholderImage
success:(void (^)(NSURLRequest *request, NSHTTPURLResponse * _Nullable response, UIImage *image))success
failure:(void (^)(NSURLRequest *request, NSHTTPURLResponse * _Nullable response, NSError *error))failure
-(UICollectionViewCell *) collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
LabelCollectionViewCell *customCell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
[[customCell nameLabel]setText:[namelabelArray objectAtIndex:indexPath.item]];
[[customCell idLabel]setText:[idArray objectAtIndex:indexPath.item]];
[[customCell imageView] setImageWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[imagArray objectAtIndex:indexPath.row]]]
placeholderImage:nil
success:nil
failure:^(NSURLRequest * _Nonnull request, NSHTTPURLResponse * _Nullable response, NSError * _Nonnull error) {
}];
return customCell;
}

First of all, instead of UIImage *imageArray; it should be NSString *imageURLString;
and then since you are using AFNetworking better to load images async (use #import UIImageView+AFNetworking.h).
NSURL *imageURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#", self.baseURL, imageURLString]];
[self setImageWithURLRequest:[NSURLRequest requestWithURL:imageURL]
placeholderImage:placeholder
success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
if (image)
{
weakSelf.image = image;
}
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
}];
