在Swift中，我已经使用联系人UI框架显示了手机中的联系人，并选择了特定联系人。选择后，需要在下一个View Controller中显示所选的联系人。
此代码属于contactUI框架的显示联系人。当我们运行此代码时，它会显示电话中的所有联系人，并带有2个按钮，例如完成或取消。当我选择联系人并按完成按钮时，它应该导航到另一个视图Controller Plz为我提供解决方案。

(contact, cursor) -> Void in
self.results.append(contact)

{
print("Handle the error please")

func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) {
contacts.forEach { contact in
for number in contact.phoneNumbers {
print("The number of \(contact.givenName) is: \(number.value)")

func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

@interface ViewController ()
{

@implementation ViewController
@synthesize listTblView,selectAll;

//For fetching contact list from phone call this one

if (granted == YES)

}
for (CNLabeledValue *label in contact.phoneNumbers) {

if ([phone length] > 0) {

}
}
NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,@"fullName",profileImage,@"userImage",phone,@"PhoneNumbers", nil];
[titleArr addObject:[NSString stringWithFormat:@"%@",[personDict objectForKey:@"fullName"]]];
NSLog(@"The contactsArray are - %@",titleArr);
}
dispatch_async(dispatch_get_main_queue(), ^{
[listTblView reloadData];
});
}
}
}];
}
对于选择特定项目，请调用此方法
-(IBAction)addButtonPressed:(UIButton *)sender
{
CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.listTblView];
NSIndexPath *indexPath = [self.listTblView indexPathForRowAtPoint:buttonPosition];
TableViewCell *cell = [self.listTblView cellForRowAtIndexPath:indexPath];
NSString *tagString = [NSString stringWithFormat:@"%@",cell.title.text];
NSLog(@"title is : %@",tagString);
if(!sender.selected)
{
sender.selected = YES;
[selectedBtnArray addObject:tagString];
}else{
sender.selected = NO;
[selectedBtnArray removeObject:tagString];
}
NSLog(@"%@",selectedBtnArray);
if (selectedBtnArray. count == titleArr.count)
selectAll.selected = YES;
else
selectAll.selected = NO;
}
For select all and de select all call this method
-(IBAction)selectAndDeselectAll:(id)sender
{
if(!selectAll.selected)
{
[selectedBtnArray removeAllObjects];
selectAll.selected = YES;
for(NSString *name in titleArr)
[selectedBtnArray addObject:name];
}else{
selectAll.selected = NO;
[selectedBtnArray removeAllObjects];
}
NSLog(@"%@",selectedBtnArray);
[listTblView reloadData];
}
将所选的内容保存在用户默认设置中
[[NSUserDefaults standardUserDefaults]setObject:selectedBtnArray forKey:@"test"];
[[NSUserDefaults standardUserDefaults]synchronize];
在NextViewController中，在viewDidLoad中检索用户默认值
NSArray *arr = [[NSUserDefaults standardUserDefaults] objectForKey:@"test"];
NSLog(@"comtactList :>>>>%@",arr);
