get data from service in custom UITable View in Objective c - ios

Question

enter image description here .Im new to IOS. I am making an app where I want to get data from there in UITableView.
I have seen many blogs and post related to getting data in custom style, but I don't get my answer. I want to show an image in UIImageView and some labels values in label from service. Im using built in service to get data.
There are many post related to static data loading on custom. Can anyone guide how can I load data in my own custom style UItable VIEW FROM SERVICE?

Somewhat I can understand your question.My answer is here
FindHomeViewController.m
#import "FindHomeViewController.h"
#import "DataTableViewController.h"
#interface FindHomeViewController ()
#end
#implementation FindHomeViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
- (IBAction)Search:(id)sender {
//Getting response from server
NSDictionary *parameters = #{
#"country": #"UAE",
#"city": #"Dubai",
#"propertytype": #"Office",
#"propertystatus": #"Av‌​ailable",
#"propertyarea" : #"Kanal",
#"minprice" : #"800",
#"maxprice" : #"900"
};
NSData *data = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:nil];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://www.pk.house/app_webservices/get_properties.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"content-type"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *dataTask = [session uploadTaskWithRequest: request
fromData:data completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if(data != nil)
{
NSError *parseError = nil;
//If the response is in dictionary format
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:data options:0 error:&parseError];
NSArray *arr=[dictionary valueForKey:#"property_data"];
NSLog(#"arr:%#",arr);
//Updating UIMain Thread
dispatch_async(dispatch_get_main_queue(), ^{
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
DataTableViewController *vc = [sb instantiateViewControllerWithIdentifier:#"DataTableViewController"];
vc.arrResprev = [arr mutableCopy];
[self.navigationController pushViewController:vc animated:YES];
});
}
else
NSLog(#"Data returned the parameter is nil here");
}];
[dataTask resume];
}
See my Custom Cell Image View
CustomeCell.h
#import <UIKit/UIKit.h>
#interface CustomCell : UITableViewCell
#property (nonatomic,strong) IBOutlet UILabel *nameLabel;
#property (nonatomic,strong) IBOutlet UILabel *priceLabel;
#property (nonatomic,strong) IBOutlet UILabel *locationLabel;
#property (nonatomic,strong) IBOutlet UIImageView *imgvwRes;
#end
CustomCell.m
#import "CustomCell.h"
#implementation CustomCell
- (void)awakeFromNib {
[super awakeFromNib];
// Initialization code
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
#end
DataTableViewController.h
#import <UIKit/UIKit.h>
#interface DataTableViewController : UIViewController<UITableViewDelegate,UITableViewDataSource>
#property (strong, nonatomic) IBOutlet UITableView *tvCustomers;
#property (strong, nonatomic) NSMutableArray *listOfCustomers;
#property (strong, nonatomic) NSMutableArray *arrResprev;
#end
DataTableViewController.m
#import "DataTableViewController.h"
#import "CustomCell.h"
#interface DataTableViewController ()
#end
#implementation DataTableViewController
#synthesize tvCustomers,arrResprev,listOfCustomers;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
listOfCustomers = [[NSMutableArray alloc]init];
listOfCustomers = arrResprev;
[tvCustomers reloadData];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return listOfCustomers.count;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 134;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CustomCell *cell = (CustomCell *)[tvCustomers dequeueReusableCellWithIdentifier:#"cell"];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
if(cell == nil){
cell = nib[0];
}
cell.nameLabel.text = [NSString stringWithFormat:#"%#",[[listOfCustomers objectAtIndex:indexPath.row]objectForKey:#"dealer_name"]];
cell.priceLabel.text = [NSString stringWithFormat:#"%#",[[listOfCustomers objectAtIndex:indexPath.row]objectForKey:#"price"]];
cell.locationLabel.text = [NSString stringWithFormat:#"%#",[[listOfCustomers objectAtIndex:indexPath.row]objectForKey:#"location"]];
NSString *strImgURL = [NSString stringWithFormat:#"%#",[[listOfCustomers objectAtIndex:indexPath.row]objectForKey:#"images"]];
NSError* error = nil;
NSURL *fileURL = [NSURL fileURLWithPath:strImgURL];
NSData* data = [NSData dataWithContentsOfURL:fileURL options:NSDataReadingUncached error:&error];
if (error) {
NSLog(#"%#", [error localizedDescription]);
} else {
NSLog(#"Data has loaded successfully.");
}
UIImage *img = [[UIImage alloc] initWithData:data];
cell.imgvwRes.image = omg;
return cell;
}

Answer 2

For this you need to follow both Appcoda and mikesknowledgebase tutorials .
One shows how to customize UITableViewCell and other shows how to populate UITableView with data fetched from server. You will have to do it in steps.
First, design the Custom UITableViewCell.
Then, follow Mike's tutorial to learn how to set data on cell from API call.
You will use NSURLSession to make API calls.
Follow Link to learn how to make an API call.
Go through these links.
We can only help you in debugging where little amount of code will work. But cannot post code for the complete functionality.
Hope these links will help you.
