I want to get the users most recent BMI reading from my instance of HKHealthStore. As of right now I am doing it as follows but it doesn't seem right. Is there a way to get an actual numerical value for BMI instead of a countUnit (HKUnit)?
HKQuantityType *bodyMassIndexType = [HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierBodyMassIndex];
HKSampleQuery *bmiSampleQuery = [[HKSampleQuery alloc] initWithSampleType:bodyMassIndexType predicate:nil limit:1 sortDescriptors:nil resultsHandler:^(HKSampleQuery *query, NSArray *results, NSError *error) {
if (results.count == 0)
{
//No results
}
else
{
if (!error)
{
NSString *bmiString = [NSString stringWithFormat:#"%#", [[results firstObject] quantity]];
NSString *parsedBMIString = [bmiString stringByReplacingOccurrencesOfString:#" count" withString:#""];
NSLog(#"%f", [parsedBMIString floatValue]);
}
}
}];
[self.store executeQuery:bmiSampleQuery];
The sample returns an array, so you can simply pull out the first object from the array and then convert it's value to a double for handling.
HKQuantitySample *sample = [results firstObject];
int i = [sample.quantity doubleValueForUnit:[HKUnit countUnit]];
NSLog(#"%i",i);

this is my json content.
[
{
"sha":"30eae8a47d0203ac81699d8fc2ab2632de2d0bba",
"commit":{
"author":{
"name":"Madhura Bhave",
"email":"mbhave#pivotal.io",
"date":"2017-03-23T23:14:32Z"
},
"committer":{
"name":"Madhura Bhave",
"email":"mbhave#pivotal.io",
"date":"2017-03-23T23:14:32Z"
},
"message":"Merge branch '1.5.x'",
}
}
]
and this is my main.i just want to retrieve key value from message and name,email,date from committer dictionary.i got stuck how to do that.
NSMutableArray *CommitArray = [[NSMutableArray alloc] init];
for (NSDictionary *CommitDictionary in CommitJson) {
CommitDict *commitDictObj = [[CommitDict alloc] init];
commitDictObj.message = [CommitDictionary objectForKey:#"message"];
for (NSDictionary *CommitterDictionary in [CommitDictionary objectForKey:#"committer"]) {
Committer *author = [[Committer alloc] init];
author.name = [CommitterDictionary objectForKey:#"name"];
author.email = [CommitterDictionary objectForKey:#"email"];
author.date = [CommitterDictionary objectForKey:#"date"];
}
[CommitArray addObject:commitDictObj];
}
for (int i =0 ; i < [CommitArray count] ; i++){
CommitDict *commitDictObj = [CommitArray objectAtIndex:i];
NSLog(#"Commit Message: %#", commitDictObj.message);
}
return 0;
}
}
i try fetch the json and display it value of message,name,email and date.how can i log the value of message, name, email and date?
Your array contains a dictionary, and that dictionary contains the commit dictionary, not the commit dictionary directly. Replace that part of your code:
for (NSDictionary *CommitDictionary in CommitJson) {
CommitDict *commitDictObj = [[CommitDict alloc] init];
With that:
for (NSDictionary *shaCommitDictionary in CommitJson) {
CommitDict *commitDictObj = [[CommitDict alloc] init];
NSDictionary *CommitDictionary = [shaCommitDictionary objectForKey:#"commit"];
(1) Convert JSON to NSDictionary
NSData *jsonData= ... // Assume you got the data already loaded
NSError *error = nil;
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
(2) Access the dictionary values (fast enumeration available by now!!
NSString *message = dictionary[#"message"];
NSDictionary *author = dictionary[#"author"];
NSString *name = author[#"author"];
NSString *email = author[#"author"];
NSString *date = author[#"author"];
// OR:
// NSString *name = dictionary[#"author"][#"author"];
// NSString *email = dictionary[#"author"][#"author"];
// NSString *date = dictionary[#"author"][#"author"];
And thats it. I think the tricky thing is to get the JSON Data to the NSDictionary?

I working with the Addressbook for fetch the contacts list with their labels. (like mobile, main, home, work, fax..etc). I fetched the phone, email labels from the contacts but i did not fetch the birthday, anniversary labels. Here is my code for birthday class.
ABMultiValueRef dateofbirth1 = ABRecordCopyValue(contactPerson, kABPersonBirthdayProperty); // Assign the Date Of birth
NSString *dob1=[NSDateFormatter localizedStringFromDate:(__bridge NSDate *)(dateofbirth1) dateStyle:NSDateFormatterLongStyle timeStyle:0]; // Changing to string format using Date Formatter.
if(!(dob1==nil))
{
// DOB is Not Nill
}
Here is my fetch the BirthDay Label Code
if([arrayOfDatesAsStrings count]>0)
{
for (int j = 0; j < [arrayOfDatesAsStrings count] ; j++)
{
**//This is the fetching birthday label code and following code is crashed**
CFStringRef locLabel1 = ABMultiValueCopyLabelAtIndex((__bridge ABMultiValueRef)(dob1), j);
NSString *phoneLabel1 =(__bridge NSString*) ABAddressBookCopyLocalizedLabel(locLabel1);
personD.dateOfBirth = phone1;
NSLog(#" %# %#",phoneLabel1,personD.dateOfBirth);
}
}
else
{
NSLog(#"Date Of Birth was Not set ");
}
What can i do for this? can Any one help me? The Crash Error Message is :

I am working on Action Extension Objective C. I have successfully created Extension for share recent contact in my Extension. In that I am getting v Card String. How can I get Mobile Number from v Card String. Any help would be appreciated.
Using contactsWithData:error: class method of CNContactVCardSerialization, you can retrieve info from a vCard.
It's from Contacts.framework, available since iOS9.
For earlier version, you can use AddressBook.framework. You can read info here.
NSError *errorVCF;
NSArray *allContacts = [CNContactVCardSerialization contactsWithData:[contactStr dataUsingEncoding:NSUTF8StringEncoding] error:&errorVCF];
if (!errorVCF)
{
NSMutableString *results = [[NSMutableString alloc] init];
//NSLog(#"AllContacts: %#", allContacts);
for (CNContact *aContact in allContacts)
{
NSArray *phonesNumbers = [aContact phoneNumbers];
for (CNLabeledValue *aValue in phonesNumbers)
{
CNPhoneNumber *phoneNumber = [aValue value];
[results appendFormat:#"%# %#\n", [aValue label], [phoneNumber stringValue]];
}
}
NSLog(#"Final: %#", results);
}
I'm working on iOS application with foursquare iOS api , I want to get the recommended near venues. I have used following code & it giving me an empty result .. Where have I done the mistake ? ? ?
NSArray* venues;
//get the foursquare locations
- (void)getTipsForLocation:(CLLocation *)location {
//NSLog(#"lat %f",location.coordinate.latitude);
[Foursquare2 venueExploreRecommendedNearByLatitude:#(location.coordinate.latitude)
longitude:#(location.coordinate.longitude)
near:nil
accuracyLL:nil
altitude:nil
accuracyAlt:nil
query:nil
limit:nil
offset:nil
radius:#(1500)
section:nil
novelty:nil
sortByDistance:1
openNow:0
venuePhotos:0
price:nil
callback:^(BOOL success, id result){
if (success) {
NSDictionary *dic = result;
venues = [dic valueForKeyPath:#"response.venues"];
FSConverter *converter = [[FSConverter alloc]init];
self.nearbyVenues = [converter convertToObjects:venues];
//NSLog(#"venues %#",venues);
//NSLog(#"near by places %#",self.nearbyVenues);
}
else{
NSLog(#" foursquare connecting error");
}
}];
NSLog(#"recommended place array %#",venues);
}
You Can Not pass Nil,In NSNumber & NSString.
NSNumber *emptynumber=[[NSNumber alloc] init];
[Foursquare2 venueExploreRecommendedNearByLatitude:lan longitude:lon near:#"" accuracyLL:emptynumber altitude:emptynumber accuracyAlt:emptynumber query:#"" limit:emptynumber offset:emptynumber radius:#(1500) section:#"" novelty:#"" sortByDistance:YES openNow:YES venuePhotos:YES price:#"" callback:^(BOOL success, id result) {
if (success) {
NSLog(#"secondResult: %#",result);
NSDictionary *dic = result;
NSArray *venues = [dic valueForKeyPath:#"response.venues"];
FSConverter *converter = [[FSConverter alloc] init];
self.venues = [converter convertToObjects:venues];
[self.tableView reloadData];
NSLog(#"Data: %#",venues);
}
}];
It Works For me.
I have some JSON data which is pulled from a URL. The code I have written works fine to download the JSON and parse it, but I cannot seem to access it how I need too, especially where the data is contained as a sub-element of another one.
Here is the JSON format:
{
address = "<null>";
city = "<null>";
country = UK;
"country_code" = GB;
daylight = 1;
for = daily;
items = (
{
asr = "5:22 pm";
"date_for" = "2013-7-1";
dhuhr = "1:01 pm";
fajr = "2:15 am";
isha = "11:47 pm";
maghrib = "9:24 pm";
shurooq = "4:39 am";
}
);
latitude = "50.9994081";
link = "http://muslimsalat.com/UK";
longitude = "0.5039011";
"map_image" = "http://maps.google.com/maps/api/staticmap?center=50.9994081,0.5039011&sensor=false&zoom=13&size=300x300";
"postal_code" = "<null>";
"prayer_method_name" = "Muslim World League";
"qibla_direction" = "119.26";
query = "51.000000,0.500000";
state = "<null>";
timezone = 0;
title = UK;
"today_weather" = {
pressure = 1020;
temperature = 14;
};
}

My Objective-C so far is this:
-(CLLocationCoordinate2D) getLocation{
CLLocationManager *locationManager = [[[CLLocationManager alloc] init] autorelease];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];
return coordinate;
}
//class to convert JSON to NSData
- (IBAction)getDataFromJson:(id)sender {
//get the coords:
CLLocationCoordinate2D coordinate = [self getLocation];
NSString *latitude = [NSString stringWithFormat:#"%f", coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:#"%f", coordinate.longitude];
NSLog(#"*dLatitude : %#", latitude);
NSLog(#"*dLongitude : %#",longitude);
//load in the times from the json
NSString *myURLString = [NSString stringWithFormat:#"http://muslimsalat.com/%#,%#/daily/5.json", latitude, longitude];
NSURL *url = [NSURL URLWithString:myURLString];
NSData *jsonData = [NSData dataWithContentsOfURL:url];
if(jsonData != nil)
{
NSError *error = nil;
id result = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];
NSArray *jsonArray = (NSArray *)result; //convert to an array
if (error == nil)
NSLog(#"%#", result);
NSLog(#"%#", jsonArray);
for (id element in jsonArray) {
NSLog(#"Element: %#", [element description]);
}
}
}
When running this code, the only output I get is a list of element names (address, city, country, so on). items is given, but not its child elements. I understand that this is what I am asking the code for with:
for (id element in jsonArray) {
NSLog(#"Element: %#", [element description]);
}
but I do not know how to move onto the next step.
The only data values which I require are in fact the times themselves (so, items>asr, items>dhuhr, etc).
How can I get these values themselves and then save them as values I can work with?
Thank you!
(...); - is Array
{...}; - is Dictionary
so your "element" is Dictionary
use objectForKey:
example:
for (id element in jsonArray) {
NSLog(#"Element asr: %#", [element objectForKey:#"asr"]); // or element[#"asr"]
}
NSArray *jsonArray = (NSArray *)result; //convert to an array
This doesn't 'convert', it's just you promising the compiler that result is really an NSArray. And in this case it's a lie.
Your code is currently just printing a list of the keys in the dictionary that is returned in the JSON. Try this to get to the list of items (it's an array so you need to deal with there possibly being multiple entries):
NSDictionary *result = [NSJSONSerialization ...
for (NSDictionary *itemDict in result[#"items"]) {
NSLog(#"item: %#", itemDict);
}
Then you can extract the times.
You can extract info by following:
NSError* error = nil;
NSDictionary *userInfo; //your main data
if([NSJSONSerialization class])
userInfo = [NSJSONSerialization JSONObjectWithData:[request responseData] options:kNilOptions error:&error];
//to extract items
NSDictionary *items = [[[userInfo objectForKey:#"items"] JSONValue] objectAtIndex:0];
