iOS: How to display parameters in response in tableview? - ios

Question

I am trying to set up a UITableView inside of a UIViewController. I am using storyboard. but when running it on the simulator, the tableview does not display any content. Here is what i tried in Xcode:
1) Drag a table view on UIView.
2) Connect it's outlets (dataSource and delegate).
3) I get response from server like:
[{"email_id":"adas#faga.gs","id":66,"mobile_no":"1236547895","name":"asad","relation":"dsfs"},{"email_id":"raj#ghj.com","id":67,"mobile_no":"5632145412","name":"raj","relation":"xyz"}]
4)Now what i want to do:
In 1st cell i want to display,
name:asad mobile:[phone] email:adas#faga.gs relation:dsfs
and in 2nd cell,
name:raj mobile:[phone] email:raj#ghj.com relation:xyz
But i have no idea about how to do this.Please anyone can solve my issue. help will be appreciable.
I do like following way but it's not working.
a) Add a new file to the project, with the Objective-C class template. Name it EmergencyContactCell and make it a subclass of UITableViewCell.
b) then in EmergencyContactCell.h
#interface EmergencyContactCell : UITableViewCell
#property (nonatomic, weak) IBOutlet UILabel *name;
#property (nonatomic, weak) IBOutlet UILabel *email;
#property (nonatomic, weak) IBOutlet UILabel *mobile;
#property (nonatomic, weak) IBOutlet UILabel *relation;
c) then MainStoryboard.storyboard, select the prototypecell and in the Identity Inspector change its class to EmergencyContactCell
d) Then connect all outlets
e) I am using AFNetworking to take response from server, when i got response, after that i do like following way:
NSArray *ResponseArray = [NSJSONSerialization JSONObjectWithData: responseObject options: kNilOptions error: nil];
if (ResponseArray.count >0)
{
menuItems = [ResponseArray mutableCopy];
[yourTableviewname reloadData];
}
f) and for display it on cell,
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [menuItems count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"EmergencyContactCell";
//static NSString *simpleTableIdentifier = #"cell";
EmergencyContactCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
// NSDictionary *content = [menuItems objectAtIndex:indexPath.row];
// cell.textLabel.text = [NSString stringWithFormat:#"Name:%#, Mobile:%#, Email:%#, Relation:%#",content[#"name"],content[#"mobile_no"],content[#"email_id"],content[#"relation"]];
//
return cell;
}
I'm not getting what to do at last??

Step-1
No need of this
NSArray *ResponseArray = [NSJSONSerialization JSONObjectWithData: responseObject options: kNilOptions error: nil];
NSMutableArray *finalArray = [NSMutableArray array];
for (NSDictionary *temp in ResponseArray) {
[finalArray addObject:temp[#"name"]];
}
NSLog(#"%#",finalArray);
if(finalArray != nil && finalArray.count > 0){
menuItems=[NSArray arrayWithArray:finalArray];
NSLog(#"menu items: %#",menuItems);
}
else{
NSLog(#"zero values from server");
}
Simply Do like
NSArray *ResponseArray = [NSJSONSerialization JSONObjectWithData: responseObject options: kNilOptions error: nil];
if (ResponseArray.count >0)
{
menuItems = [ResponseArray mutableCopy];
[yourTableviewname reloadData];
}
Step-2
for your answer continution
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
NSDictionary *content = [menuItems objectAtIndex:indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:#"Name:%#, Mobile:%#, Email:%#, Relation:%#",content[#"name"],content[#"mobile_no"],content[#"email_id"],content[#"relation"]];
return cell;
}
Updated Answer
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"EmergencyContactCell";
EmergencyContactCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSDictionary *content = [menuItems objectAtIndex:indexPath.row];
cell.name.text = [NSString StringWithFormat:#"Name:%#",content[#"name"]];
cell.email.text = [NSString StringWithFormat:#"email:%#",content[#"email"]];
cell.mobile.text = [NSString StringWithFormat:#"mobile:%#",content[#"mobile"]];
cell.relation.text = [NSString StringWithFormat:#"relation:%#",content[#"relation"]];
return cell;
}

You need to do 2 things
After getting response set that into one NSArray. Declare NSArray
global one. And your code should be like
NSArray *arrayPersonalInfo = responseObject; // responseObject is response
got from server. Then call [tableView reloadData];
Now update your table view methods to
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return arrayPersonalInfo.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpleTableIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
NSDictionary *dictionaryMenu = [arrayPersonalInfo objectAtIndex:indexPath.row]; // It will save dictionary object of index
cell.textLabel.text = [NSString stringWithFormat:#"Name:%# Mobile:%# Email:%# Relation:%#",[dictionaryMenu valueForKey:#"name"],[dictionaryMenu valueForKey:#"mobile_no"],[dictionaryMenu valueForKey:#"email_id"],[dictionaryMenu valueForKey:#"relation"]];
cell.textLabel.numberOfLines = 0;
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
return cell;
}
If needed add other table view methods like
heightForRowAtIndexPath and numberOfSections

If you prefer using storyboard, you can actually add a label into a prototype cell, make sure you set the prototype's cellIdentifier correctly to use it in codes. Then set a unique tag to your label. From your codes you can call viewWithTag from your cell's contentView to get the label and edit it's text property.
