How to pass a Dictionary data from table View to the another View Controller - objective-c

Question

I am fetching the contacts of iPhone and make their Dictionary Check my code
-(void) fetchContacts
{
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted == YES) {
//keys with fetching properties
NSArray *keys = #[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSString *containerId = store.defaultContainerIdentifier;
NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
NSError *error;
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
if (error) {
NSLog(#"error fetching contacts %#", error);
} else {
NSString *phone;
NSString *fullName;
NSString *firstName;
NSString *lastName;
UIImage *profileImage;
NSMutableArray *contactNumbersArray;
for (CNContact *contact in cnContacts) {
// copy data to my custom Contacts class.
firstName = contact.givenName;
lastName = contact.familyName;
if (lastName == nil) {
fullName=[NSString stringWithFormat:#"%#",firstName];
}else if (firstName == nil){
fullName=[NSString stringWithFormat:#"%#",lastName];
}
else{
fullName=[NSString stringWithFormat:#"%# %#",firstName,lastName];
}
UIImage *image = [UIImage imageWithData:contact.imageData];
if (image != nil) {
profileImage = image;
}else{
profileImage = [UIImage imageNamed:#"acc_sett.png "];
}
for (CNLabeledValue *label in contact.phoneNumbers) {
phone = [label.value stringValue];
if ([phone length] > 0) {
[contactNumbersArray addObject:phone];
}
}
NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,#"fullName",profileImage,#"userImage",phone,#"PhoneNumbers", nil];
[_Contacts addObject:personDict];
NSLog(#"%#",phone);
NSLog(#"%#",fullName);
}
dispatch_async(dispatch_get_main_queue(), ^{
[self.contacttableview reloadData];
});
}
}
}];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [_Contacts count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary* personDict = [_Contacts objectAtIndex:indexPath.row];
UITableViewCell *cell = nil;
cell = [_contacttableview dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
cell.imageView.image = [personDict objectForKey:#"userImage"];
cell.textLabel.text = [personDict objectForKey:#"fullName"];
cell.detailTextLabel.text = [personDict objectForKey:#"phoneNumbers"];
return cell;
}
With the help of this code Dictionary Data is display on the tableview now i want to pass image fullname and phone number of a person on the another view controller on selecting their row.
I have tried many method but not get any result

Answer 1

In YourViewController.h, create a property of Person that you want to pass
#property (nonatomic, assign) NSDictionary *person;
In TableViewController.m, didSelectRowAtIndexPath:
YourViewController *vc = [[YourViewController alloc] init];
vc.person = [_Contacts objectAtIndex:indexPath.row];
[self.navigationController pushViewController:vc animated:YES];

Answer 2

First create any NSDictionary object or Your model class object on OtherViewController where you want to navigate then write code like Below,
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
OtherViewController *VC = [[OtherViewController alloc] init];
VC.objContactModel = [_Contacts objectAtIndex:indexPath.row];
[self.navigationController pushViewController:VC animated:YES];
}
Hope it will work.
