My question is in the title. I just want to have the list of all the cities in the world (422 objects) and I have only examples with data written one by one with "add object".
I do hope there is another trick for my lazy fingers !
I have create this but it doesn't match.
NSArray * timeZones = [NSTimeZone knownTimeZoneNames];
maListe = [[NSMutableArray alloc] init];
// création dictionnaire
NSDictionary *tampon = [NSDictionary dictionary];
for (NSString *aLocation in timeZones)
{
NSArray *continentsCountryCity = [aLocation componentsSeparatedByString:#"/"];
if ([continentsCountryCity count] >= 2)
{
NSMutableArray *continentPickerView = [continentsCountryCity objectAtIndex:0];
NSMutableArray *villePickerView = [continentsCountryCity objectAtIndex:1];
[tampon setObject:villePickerView forKey:continentPickerView];
}
}
maListe = tampon.allKeys;
Does anybody have a solution ?
Many thanks for your help.

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 have a NSString like this one:
NSString* allSeats = #"1_Male,2_Female,3_Female,4_Male";
I want to split the NSString based on the keywords _Male & _Female and then make two separate strings like these:
NSString* maleSeats = #"1,4";
NSString* femaleSeats = #"2,3";
based on the contents of allSeats variable declared above.
How it will be possible to split NSString and then make 2 seperate strings?
You have to do it yourself. There is no "all done" solution. There are a few ways to do it.
Note: I didn't try my code, I just wrote it, it may don't even compile. But the important thing is that you get the whole idea behind it.
One way could be this one:
NSString *maleSufffix = #"_Male";
NSString *femaleSufffix = #"_Female";
NSMutableArray *femaleSeatsArray = [[NSMutableArray alloc] init];
NSMutableArray *maleSeatsArray = [[NSMutableArray alloc] init];
NSArray *array = [allSeats componentsSeparatedByString:#","];
for (NSString *aSeat in array)
{
if ([aSeat hasSuffix:maleSuffix])
{
[maleSeatsArray addObject:[aSeat stringByReplacingOccurencesOfString:maleSuffix withString:#""]];
}
else if ([aSeat hasSuffix:femaleSuffix])
{
[femalSeatsArray addObject:[aSeat stringByReplacingOccurencesOfString:femaleSuffix withString:#""]];
}
else
{
NSLog(#"Unknown: %#", aSeat);
}
}
NSString *maleSeats = [maleSeatsArray componentsJoinedByString:#","];
NSString *femaleSeats = [femaleSeatsArray componentsJoinedByString:#","];
Of course, you could use different methods on array, enumerating it, use a NSMutableString instead of a NSMutableArray (for femaleSeatsArray or maleSeatsArray, and use adequate methods then in the for loop).
I derived an idea from Larme's Clue and it works as :
Make a method as and call it anywhere :
-(void)seperateSeat
{
maleSufffix = #"_Male";
femaleSufffix = #"_Female";
femaleSeatsArray = [[NSMutableArray alloc] init];
maleSeatsArray = [[NSMutableArray alloc] init];
array = [self.selectedPassengerSeat componentsSeparatedByString:#","];
for (aSeat in array)
{
if ([aSeat hasSuffix:maleSufffix])
{
aSeat = [aSeat substringToIndex:[aSeat length]-5];
NSLog(#"%# is value in final seats ::",aSeat );
[maleSeatsArray addObject:aSeat];
}
else if ([aSeat hasSuffix:femaleSufffix])
{
aSeat = [aSeat substringToIndex:[aSeat length]-7];
NSLog(#"%# is value in final seats ::",aSeat );
[femaleSeatsArray addObject:aSeat];
}
}
totalMales = [maleSeatsArray componentsJoinedByString:#","];
totalFemales = [femaleSeatsArray componentsJoinedByString:#","];
NSLog(#"maleSeatsAre::::%#",totalMales);
NSLog(#"maleSeatsAre::::%#",totalFemales);
}
I imported MBCalendar Kit into my project, and I don't know how to add an event or array of events in calendar. I found this code:
NSMutableDictionary *eventsDict = [[NSMutableDictionary alloc] init];
for (int i =0; i< eventsArray.count ;i++)
{
// Create events
eventsDict = eventsArray[i];
CKCalendarEvent* aCKCalendarEvent = [[CKCalendarEvent alloc] init];
aCKCalendarEvent.title = [eventsDict objectForKey:#"email"];
aCKCalendarEvent.date = date; //[eventsArray objectForKey:#"phone"];
aCKCalendarEvent.address = [eventsDict objectForKey:#"addrLine1"];
aCKCalendarEvent.image = [eventsDict objectForKey:#"pPic"];
aCKCalendarEvent.name = [eventsDict objectForKey:#"fname"];
aCKCalendarEvent.appDate = [eventsDict objectForKey:#"apntDt"];
aCKCalendarEvent.notes = [eventsDict objectForKey:#"notes"];
aCKCalendarEvent.phone = [eventsDict objectForKey:#"phone"];
[myeventsArray addObject: aCKCalendarEvent];
}
[_data setObject:myeventsArray forKey:date];
but I don't know where to write it, or how to use it. Can anyone help me?
Thank you.
I'm working with this Framework and I've had the same issues.
What worked for me was to use the NSDate+Components category, specifically the dayWithDay:month:year method to create the dates for the events, then create as many events as you want the way you're doing it, encapsulate all the events that are on the same day in an array and lastly setting that array as an object for the NSDictionary data with the previously created as the key to that array. Here's an example:
NSDate *eventDate1 = [NSDate dateWithDay:8 month:8 year:2014];
NSDate *eventDate2 = [NSDate dateWithDay:9 month:8 year:2014];
CKCalendarEvent *event1 = [CKCalendarEvent eventWithTitle:#"Event 1" andDate:eventDate1 andInfo:nil];
CKCalendarEvent *event2 = [CKCalendarEvent eventWithTitle:#"Event 2" andDate:eventDate2 andInfo:nil];
NSArray *today = [NSArray arrayWithObjects:event1, nil];
NSArray *tomorrow = [NSArray arrayWithObjects:event2, nil];
[[self data] setObject:today forKey:eventDate1];
[[self data] setObject:tomorrow forKey:eventDate2];
Hope this helps :D
I'm working on my own framework based on this but with an iOS7 native feel, it's not finished yet but here is the repo:

What's the problem with this code?? I am trying to put the data from an NSArray to a NSMutableDictionary but I do not want to first split the initial nsarray into two and then send the data to the nsdcitionary.
The problem is that when I NSLog de mutabledictionary it returns me just the 1 item which happens to be the last data from the NSArray.
NSString *str = #"13:00,2.00,13:05,2.03,13:10,2.07,13:15,2.01,13:20,2.08,13:25,2.10,13:30,2.15";
NSArray *arrayFinal = [str componentsSeparatedByString:#","];
NSMutableDictionary *dict = [NSMutableDictionary new];
for (int i = 0; i < [arrayFinal count ]; i = i + 2) {
[dict setObject:[arrayFinal objectAtIndex:i] forKey:#"hora"];
[dict setObject:[arrayFinal objectAtIndex:i+1] forKey:#"preco"];
}
The result is:
2013-09-04 20:27:33.732 separa[1438:c07] {
hora = "13:30";
preco = "2.15";
}
Any help will be appreciated.
for (int i = 0; i < [arrayFinal count ]; i = i + 2) {
[dict setObject:[arrayFinal objectAtIndex:i+1] forKey:[arrayFinal objectAtIndex:i]];
}
You need each key to point to an array of values. Something like this:
NSString *str = #"13:00,2.00,13:05,2.03,13:10,2.07,13:15,2.01,13:20,2.08,13:25,2.10,13:30,2.15";
NSArray *arrayFinal = [str componentsSeparatedByString:#","];
NSMutableArray *horas = [NSMutableArray new];
NSMutableArray *precos = [NSMutableArray new];
for (int i = 0; i < [arrayFinal count]; i += 2) {
[horas addObject:arrayFinal[i]];
[precos addObject:arrayFinal[i + 1]];
}
NSMutableDictionary *dict = [NSMutableDictionary new];
dict[#"hora"] = horas;
dict[#"preco"] = precos;
You're going to need to separate the two (hours and prices) into their own NSMutableArrays, then store each array as one of the keys, something like this:
NSMutableArray *hora = [NSMutableArray alloc] init];
NSMutableArray *preco = [NSMutableArray alloc] init];
NSString *str = #"13:00,2.00,13:05,2.03,13:10,2.07,13:15,2.01,13:20,2.08,13:25,2.10,13:30,2.15";
NSArray *arrayFinal = [str componentsSeparatedByString:#","];
NSMutableDictionary *dict = [NSMutableDictionary alloc] init];
for (int i = 0; i < [arrayFinal count ]; i = i + 2)
{
[hora addObject:[arrayFinal objectAtIndex:i];
[preco addObject:[arrayFinal objectAtIndex:i+1];
}
[dict setObject:hora forKey:#"hora"];
[dict setObject:preco forKey:#"preco"];
Probably not exactly the way I'd do it, but I think it is the concept you're looking for.
I am using NSXML to parse out an XML document and add the results to an array of objects. The array has the correct number of objects, but they are full of data from the last object.(i.e. the object at index 0 has the same data as at index 3). I am getting good data back from my server.
//set up my objects and arrays higher in my structure
SignatureResult *currentSignatureResult = [[SignatureResult alloc]init];
Document *currentDoc = [[Document alloc]init];
Role *currentRole = [[Role alloc]init];
NSMutableArray *roleArray = [[NSMutableArray alloc] init];
NSMutableArray *doclistArray2 = [[NSMutableArray alloc] init];
.....there is more parsing up here
//role is defined as an NSXML Element
for (role in [roleList childrenNamed:#"role"]){
NSString *firstName =[role valueWithPath:#"firstName"];
NSString *lastName = [role valueWithPath:#"lastName"];
currentRole.name = [NSString stringWithFormat:#"%# %#",firstName, lastName];
for (documentList2 in [role childrenNamed:#"documentList"])
{
SMXMLElement *document = [documentList2 childNamed:#"document"];
currentDoc.name = [document attributeNamed:#"name"];
[doclistArray2 addObject:currentDoc];
}
currentRole.documentList = doclistArray2;
[roleArray addObject:currentRole];
///I've logged currentRole.name here and it shows the right information
}//end of second for statemnt
currentSignatureResult.roleList = roleArray;
}
///when I log my array here, it has the correct number of objects, but each is full of
///data from the last object I parsed
The cause is that the addObjects: retains for your currentRole object and not creates a copy from that. You can create your new currentRole object inside of the for or you can create a copy from that and add it to the array.
I recommend the following:
for (role in [roleList childrenNamed:#"role"]){
Role *currentRole = [[Role alloc] init];
NSString *firstName =[role valueWithPath:#"firstName"];
NSString *lastName = [role valueWithPath:#"lastName"];
currentRole.name = [NSString stringWithFormat:#"%# %#",firstName, lastName];
for (documentList2 in [role childrenNamed:#"documentList"])
{
SMXMLElement *document = [documentList2 childNamed:#"document"];
currentDoc.name = [document attributeNamed:#"name"];
[doclistArray2 addObject:currentDoc];
}
currentRole.documentList = doclistArray2;
[roleArray addObject:currentRole];
///I've logged currentRole.name here and it shows the right information
[currentRole release];
}//end of second for statemnt
