How to map Web-Services key and values pairs using NSObject? - ios

Question

Hi I have used NsurlSession for integrating web services when I get response from services I am using NSObject for mapping key and values pairs.
After the process is done in NSObject class I want to display that data in my TableList.
For this I wrote the code below, but after mapping all objects in my NSObject class.
How can I display them in tableList?
Please help me.
mainclass:-
#import "ViewController.h"
#interface ViewController (){
BacGroundGetMethodServiceClass * get;
ModelObject1 * model1;
NSString * alertmessage;
UITableView * MaintableView;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
get = [[BacGroundGetMethodServiceClass alloc]init];
get.delegate = self;
[get getServieCalling:#"my url"];
model1 = [[ModelObject1 alloc]init];
}
//got response here from services using protocols
- (void) GetCallService1: (id)MainResponse{
dispatch_async(dispatch_get_main_queue(), ^{
if ([MainResponse isKindOfClass:[NSDictionary class]] && MainResponse[#"error"]){
alertmessage = [MainResponse objectForKey:#"message"];
[self ShowingAlertMesaage:alertmessage];
}else if ([MainResponse count] == 0){
[self ShowingAlertMesaage:#"Server not responding please try again"];
}
else{
[model1 loadingservices :MainResponse];
}
});
}
//Crating TableList :-
-(void)createTableList{
//Create UITableList:-
[MaintableView removeFromSuperview];
MaintableView = [[UITableView alloc] initWithFrame:CGRectMake(5, 118, self.view.frame.size.width-10, self.view.frame.size.height-75) style:UITableViewStylePlain];
MaintableView.delegate = self;
MaintableView.dataSource = self;
MaintableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
MaintableView.separatorStyle = UITableViewCellSeparatorStyleNone;
MaintableView.contentInset = UIEdgeInsetsMake(0, 0, 75, 0);
MaintableView.bounces = NO;
[self.view addSubview:MaintableView];
}
//TableList Delegate Methods:-
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 10;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"HistoryCell";
// Similar to UITableViewCell, but
UITableViewCell *cell = (UITableViewCell *)[MaintableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
return cell;
}
#end
model Object class:-
#import "ModelObject1.h"
#implementation ModelObject1
#synthesize MasterId,Name;
-(void)loadingservices :(id)mainDictionary{
for (NSDictionary *obj in mainDictionary) {
if([obj objectForKey:#"Name"] && [obj objectForKey:#"id"]) {
Name = [obj objectForKey:#"Name"];
MasterId = [obj objectForKey:#"id"];
}
}
}
#end

If you want a list then you need array in proper JSON object.
i.e
(
{
Name = value1,
MasterId = value2
},
{
Name = value1,
MasterId = value2
},
{
Name = value1,
MasterId = value2
}
)
You need to create multiple objects of ModelObject1, i.e if in your JSON array you have 3 objects then you need to create 3 object of your ModelObject1.
You can achieve this by creating new Method or Class.
for example here is some code.
for(int i = 0; i < array.count; i++)
{
ModelObject1 *model1 = [[ModelObject1 alloc]init];
[model1 loadingservices :array[i];
//store model1 in to any array and use that array to display list in array.
}
You can display the data as below.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return yourModelClassArray.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"HistoryCell";
// Similar to UITableViewCell, but
UITableViewCell *cell = (UITableViewCell *)[MaintableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
ModelObject1 *model1 = yourModelClassArray[indexPath.row];
cell.textLabel.text = model1.Name;
return cell;
}
