I have an app in which I am filtering the duplicate contacts I have achieved the functionality but the problem is it is quick for few contacts as the contacts are more loading also becomes slow.
Below is the block of code which I am using
-(void)loadDuplicateContacts{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[addressBook loadContacts:^(NSArray<APContact *> * _Nullable contacts, NSError * _Nullable error) {
NSMutableArray *duplucateDataArray = [[NSMutableArray alloc] init];
duplucateDataArray = [contacts mutableCopy];
duplicateContactsArray = [[NSMutableArray alloc] init];
duplicateContactsDictinary = [[NSMutableDictionary alloc] init];
self.dictionaryKeys = [NSArray new];
for (APContact *contact in duplucateDataArray) {
NSMutableArray *countArray = [[NSMutableArray alloc] init];
[duplucateDataArray enumerateObjectsUsingBlock:^(APContact *obj, NSUInteger idx, BOOL *stop)
{
if ([JustNumber([obj.phones[0] number]) isEqualToString:JustNumber([contact.phones[0] number])])
{
[countArray addObject:contact.name.compositeName];
}
}];
if (countArray.count > 1) {
if (duplicateContactsDictinary[JustNumber([contact.phones[0] number])]) {
NSMutableArray *retriveArray = [[NSMutableArray alloc] init];
retriveArray = [duplicateContactsDictinary objectForKey:JustNumber([contact.phones[0] number])];
[retriveArray addObject:contact];
[duplicateContactsDictinary setObject:retriveArray forKey:JustNumber([contact.phones[0] number])];
}else{
NSMutableArray *contactCreationArray = [[NSMutableArray alloc] init];
[contactCreationArray addObject:contact];
[duplicateContactsDictinary setObject:contactCreationArray forKey:JustNumber([contact.phones[0] number])];
}
[duplicateContactsArray addObject:contact];
}
}
dispatch_async(dispatch_get_main_queue(), ^(void) {
[self.tableView reloadData];
});
}];
});
}
Any suggestions would be more helpful

Database structure
I have a Firebase database setup (please refer to the picture).
I have a "FeedViewController" to display the contents of each post in the database. A user may post one or more posts.
When retrieving these posts from the Firebase snapshot and storing them onto a dictionary, I find that this dictionary's values are not accessible outside of the Firebase's observeEventType function.
My idea was to retrieve these key-value pairs, store them onto a NSObject custom class object (Post *post) and use this object to load the table view for my "FeedViewController". Inside the observeEventType function, I am able to access the object's values, but outside, I'm not. As a result, I don't know how to use these values to populate the table view in my FeedViewController. I understand that this observeEventType function is an asynchronous callback, but I don't know how to access the values of the object and populate my table. I don't have a clue what the dispatch_async(dispatch_get_main_queue() function is doing here. Any help would be highly appreciated. Thanks!

Your approach is what I tried to do initially. But I had problems accessing it in cellforrowatindexpath. the thing that works for me is.
- (void)configureDatabase :(NSUInteger)postsAmount{
_ref = [[FIRDatabase database] reference];
// Listen for new messages in the Firebase database
_refHandle = [[[[_ref child:#"posts"]queryOrderedByKey] queryLimitedToLast:postsAmount]observeEventType:FIRDataEventTypeChildAdded withBlock:^(FIRDataSnapshot *snapshot) {
[_posts insertObject:snapshot atIndex:0];
}];
}
Then in viewdidappear
[self configureDatabase:_numberOfPosts];
then lastly
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
FIRDataSnapshot *postsSnapshot = _posts[indexPath.section];
NSDictionary *post = postsSnapshot.value;
//use key values to create your views.
}
also include
#property (strong, nonatomic) NSMutableArray<FIRDataSnapshot *> *posts;
What this does is queries firebase for your values and receives snapshots. those snapshots are then placed in your _posts array and then you can access them in other methods.

Not entirely sure what issue you're having. If you're just wanting to insert objects into an array and a specific index - you'd do something like this:
[searchTypes insertObject: addObject:newType atIndex:0];
I am creating a table with multiple columns. In the left column I want to get the indicator name which is stored in a database and I have to check that the indicator id in database and in json (API) matches and then display the name in that column. I have tried some code

Please do help.
Well you are creating new TopicModel object which is empty! You need to use the one which you set in your viewDidLoad: method.
for (int k = 0; k < arrLeft.count; k++) {
if ([(TopicModel *)indicatorName[k] IId] == [arrLeft[k] integerValue]) {
[newArray addObject:[NSString stringWithFormat:#"%#",[(TopicModel *)indicatorName[k] IName]];
}
}
I have problem to get photos in moment wise like apple iphone have in ios8. I have implemented for ios8 using PHAsset and Photos.framework. Now, when i run same code in ios7 device then it returns nothing. So, i go with ALAssetLibrary to get photos. Using ALAssetLibrary i also got all photos but that are like albums wise photos. and also using this ALAssetLibrary i cannot get album creation date not its location name, as i have to show this to data on my each section's header.
My code for fetching photos in ios7 using ALAssetLibrary:
_imagearray = [#[] mutableCopy];
__block NSMutableArray *tmpAssets = [#[] mutableCopy];
ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
[assetLibrary enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop)
{
if (group)
{
[group setAssetsFilter:[ALAssetsFilter allAssets]];
[group enumerateAssetsWithOptions:NSEnumerationReverse usingBlock:^(ALAsset *asset, NSUInteger index, BOOL *stop) {
if (asset!=nil)
{
[tmpAssets addObject:asset];
}
}];
}
self.imagearray = tmpAssets;
NSLog (#“%#“,self.imagearray);
}
failureBlock:^(NSError *error)
{
NSLog(#"error enumerating AssetLibrary groups %#\n", error);
}];
You are out of luck with iOS 7. AssetsLibrary as you observed returns only albums (Camera Roll, user albums). Even though the Photos App in iOS 7 shows Moments, there are no developer APIs in iOS 7 to get Moments.
I found its solutions my self.

I have a function which prepares data for my UITableView:
- (void) SearchFromMyPosition {
TitleLabelSort = [[NSMutableArray alloc] init];
DistanceLabelSort = [[NSMutableArray alloc] init];
TagValueSort = [[NSMutableArray alloc] init];
DistanceUnitSort = [[NSMutableArray alloc] init];
LatArraySort = [[NSMutableArray alloc] init];
LngArraySort = [[NSMutableArray alloc] init];
// loading
[activityIndicatorObject startAnimating];
NSNumber *latNr1 = [[NSUserDefaults standardUserDefaults] valueForKey:#"api_lat"];
NSNumber *lngNr1 = [[NSUserDefaults standardUserDefaults] valueForKey:#"api_lng"];
double lat1 = [latNr1 doubleValue];
double lng1 = [lngNr1 doubleValue];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSArray *array = [APIConnection GetDataFromUrlAuth];
dispatch_async(dispatch_get_main_queue(), ^{
for (NSString *item in array) {
NSArray *coords = [[[array valueForKey:item] valueForKey:#"location"] componentsSeparatedByString:#"|"];
double lat2 = [[coords objectAtIndex:0] doubleValue];
double lng2 = [[coords objectAtIndex:1] doubleValue];
CLLocation *oldLocation = [[CLLocation alloc] initWithLatitude:lat1 longitude:lng1];
CLLocation *newLocation = [[CLLocation alloc] initWithLatitude:lat2 longitude:lng2];
CLLocationDistance meters = [newLocation distanceFromLocation:oldLocation];
[LatArraySort addObject:[NSString stringWithFormat:#"%f",lat2]];
[LngArraySort addObject:[NSString stringWithFormat:#"%f",lng2]];
[TitleLabelSort addObject:[[array valueForKey:item] valueForKey:#"name"]];
[DistanceLabelSort addObject:[NSString stringWithFormat:#"%f",meters]];
[TagValueSort addObject:item];
[self.myTableView reloadData];
[activityIndicatorObject stopAnimating];
}
});
});
}
This works but I need to sort results by DistanceLabelSort
For sorting CoreData results I use below function and works fine:
- (void) SetTableData {
TitleLabel = [[NSMutableArray alloc] init];
DistanceLabel = [[NSMutableArray alloc] init];
TagValue = [[NSMutableArray alloc] init];
DistanceUnit = [[NSMutableArray alloc] init];
LatArray = [[NSMutableArray alloc] init];
LngArray = [[NSMutableArray alloc] init];
// sorting
NSArray *sortedArray = [DistanceLabelSort sortedArrayUsingComparator:^(NSString *str1, NSString *str2) {
return [str1 compare:str2 options:NSNumericSearch];
}];
NSString *sortIdentStr = [[NSString alloc] init];
unsigned long sortIdent;
NSMutableArray *arrayUnit = [[NSMutableArray alloc] init];
for (int i = 0; i < sortedArray.count; i++) {
sortIdentStr = [sortedArray objectAtIndex:i];
sortIdent = [DistanceLabel indexOfObject:sortIdentStr];
arrayUnit = [self unitStr:sortIdentStr];
[TitleLabel addObject:[TitleLabelSort objectAtIndex:sortIdent]];
[TagValue addObject:[TagValueSort objectAtIndex:sortIdent]];
[LatArray addObject:[LatArraySort objectAtIndex:sortIdent]];
[LngArray addObject:[LngArraySort objectAtIndex:sortIdent]];
[DistanceLabel addObject:[arrayUnit objectAtIndex:0]];
[DistanceUnit addObject:[arrayUnit objectAtIndex:1]];
[self.myTableView reloadData];
[activityIndicatorObject stopAnimating];
}
}
But if I try use this for sorting data from external api function SetTableData is done before I get results from external api.
Finally I found solution and maybe this will be helpful for others:
I added function which checks if the task is done:
- (void)SearchFromMyPositionWithSuccess:(void (^)(void))successHandler failure:(void (^)(void))failureHandler {
TitleLabelSort = [[NSMutableArray alloc] init];
DistanceLabelSort = [[NSMutableArray alloc] init];
TagValueSort = [[NSMutableArray alloc] init];
DistanceUnitSort = [[NSMutableArray alloc] init];
LatArraySort = [[NSMutableArray alloc] init];
LngArraySort = [[NSMutableArray alloc] init];
// loading
[activityIndicatorObject startAnimating];
NSNumber *latNr1 = [[NSUserDefaults standardUserDefaults] valueForKey:#"api_lat"];
NSNumber *lngNr1 = [[NSUserDefaults standardUserDefaults] valueForKey:#"api_lng"];
double lat1 = [latNr1 doubleValue];
double lng1 = [lngNr1 doubleValue];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSArray *array = [APIConnection GetDataFromUrlAuth];
dispatch_async(dispatch_get_main_queue(), ^{
int i = 0;
for (NSString *item in array) {
i++;
NSArray *coords = [[[array valueForKey:item] valueForKey:#"location"] componentsSeparatedByString:#"|"];
double lat2 = [[coords objectAtIndex:0] doubleValue];
double lng2 = [[coords objectAtIndex:1] doubleValue];
CLLocation *oldLocation = [[CLLocation alloc] initWithLatitude:lat1 longitude:lng1];
CLLocation *newLocation = [[CLLocation alloc] initWithLatitude:lat2 longitude:lng2];
CLLocationDistance meters = [newLocation distanceFromLocation:oldLocation];
[LatArraySort addObject:[NSString stringWithFormat:#"%f",lat2]];
[LngArraySort addObject:[NSString stringWithFormat:#"%f",lng2]];
[TitleLabelSort addObject:[[array valueForKey:item] valueForKey:#"name"]];
[DistanceLabelSort addObject:[NSString stringWithFormat:#"%f",meters]];
[TagValueSort addObject:item];
if (i == array.count) {
successHandler();
}
[activityIndicatorObject stopAnimating];
}
});
});
}
And wait for success in this function:
-(void) SearchFromMyPosition {
[self SearchFromMyPositionWithSuccess: ^{
[self SetTableData];
NSLog(#"success");
} failure:^{
NSLog(#"failure");
}];
}
This solves my case :)
