Its only outputting one set for NSMutableDictionary not both. I want to create an JSON request using NSMutableDictionary (JSONRepresentation).
// My code
NSArray *keysEndpoint = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint = [NSArray arrayWithObjects:#"622", #"Brand", #"0", nil];
NSArray *keysEndpoint1 = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint1 = [NSArray arrayWithObjects:#"595", #"CK-05052011", #"1", nil];
NSMutableArray *keys1 = [[NSMutableArray alloc] initWithCapacity:0];
NSMutableArray *objects1 = [[NSMutableArray alloc] initWithCapacity:0];
[keys1 addObjectsFromArray:keysEndpoint];
[keys1 addObjectsFromArray:keysEndpoint1];
NSLog(#"Key Dic: %#", keys1);
[objects1 addObjectsFromArray:objectEndpoint];
[objects1 addObjectsFromArray:objectEndpoint1];
NSLog(#"Obje Dic: %#", objects1);
NSMutableDictionary *testMut = [NSMutableDictionary dictionaryWithObjects:objects1 forKeys:keys1];
NSLog(#"Test Dic: %#", testMut);
Output is am getting is this:
Test Dic: {
EndpointType = 1;
ID = 595;
Name = "CK-05052011";
}
Expexted output i want is :
Test Dic: {
EndpointType = 1;
ID = 595;
Name = "CK-05052011";
}
{
EndpointType = 0;
ID = 622;
Name = "Brand";
}
For a dictionary, adding the same keys twice will override the first set of keys. You should have a NSMutableArray of NSMutableDictionary
NSArray *keysEndpoint = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint = [NSArray arrayWithObjects:#"622", #"Brand", #"0", nil];
NSArray *keysEndpoint1 = [NSArray arrayWithObjects:#"ID", #"Name", #"EndpointType", nil];
NSArray *objectEndpoint1 = [NSArray arrayWithObjects:#"595", #"CK-05052011", #"1", nil];
NSMutableDictionary *testMut = [NSMutableDictionary dictionaryWithObjects:objectsEndpoint forKeys:keysEndpoint];
NSMutableDictionary *testMut1 = [NSMutableDictionary dictionaryWithObjects:objectsEndpoint1 forKeys:keysEndpoint1];
NSMutableArray * dictArray = [NSMutableArray arrayWithObjects:testMut,testMut1,nil];
NSLog(#"Test DictArray: %#", dictArray);

I am fresher to iOS. In my application i have 3 mutable arrays with objects like
NSMutableArray *MuteItem = [NSMutableArray alloc]initWithObjects:#"a", #"b", #"b", #"c", #"c", #"c", nil]];
NSMutableArray *MuteQuantity = [NSMutableArray alloc]initWithObjects:#"1", #"1", #"1", #"1", #"1", #"1", nil]];
NSMutableArray *MutePrice = [NSMutableArray alloc]initWithObjects:#"4", #"3", #"3", #"6", #"6", #"6", nil]];
Now i need to print that 3 mutable arrays values with counting the same item's quantity and calculate the price also like objects
MuteItem = { a, b, c }
MuteQuantity = { 1, 2, 3 } // counting of same item's quantity like {1, 1+1, 1+1+1}
MutePrice = { 4, 6, 18 } // here addition of same item's prices like {4, 3+3, 6+6+6}
So anybody, would you please help me in this problem. Thanks in advance.
This code will do exactly as you requested, and will even handle any keys in MuteItem, and will generate three new arrays with the aggregate information from each of the three original arrays.
NSMutableArray* muteItem = [[NSMutableArray alloc] initWithObjects: #"a", #"b", #"b", #"c", #"c", #"c", nil];
NSMutableArray* muteQuantity = [[NSMutableArray alloc] initWithObjects: #"1", #"1", #"1", #"1", #"1", #"1", nil];
NSMutableArray* mutePrice = [[NSMutableArray alloc] initWithObjects: #"4", #"3", #"3", #"6", #"6", #"6", nil];
NSMutableArray* setItem = [NSMutableArray array];
NSMutableArray* setQuantity = [NSMutableArray array];
NSMutableArray* setPrice = [NSMutableArray array];
NSSet* itemSet = [NSSet setWithArray: muteItem];
for (NSString* key in itemSet) {
NSIndexSet* indices = [muteItem indexesOfObjectsPassingTest: ^BOOL(id obj, NSUInteger idx, BOOL *stop) {
return [obj isEqualToString: key];
}];
__block NSInteger totalQuantity = 0;
__block NSInteger totalPrice = 0;
[indices enumerateIndexesUsingBlock: ^void(NSUInteger idx, BOOL *stop) {
totalQuantity += [[muteQuantity objectAtIndex: idx] integerValue];
totalPrice += [[mutePrice objectAtIndex: idx] integerValue];
}];
[setItem addObject: key];
[setQuantity addObject: [NSNumber numberWithInteger: totalQuantity]];
[setPrice addObject: [NSNumber numberWithInteger: totalPrice]];
}
NOTE: This code assumes you are using ARC. Also, in your original code you forgot to nil terminate your array constructors.
EDIT: I notice that your prices are integers, you may want to change them to floats if your currency uses decimal fractions. This would require changing the definition of totalPrice to float and you would want to change the end of the totalPrice += line from integerValue to floatValue.
EDIT2: Renamed all variables that started with a capital letter as this violates standard naming convention. Only class names should begin with a capital letter, variables should always begin with lowercase, or an _ for instance variables. :)
Webservice sends me JSON that looks like that:
[
{"key":"key1","value":"value1"},
{"key":"key2","value":"value2"},
{"key":"key3","value":"value3"}
]
How should I set up RestKit mapping to get the following NSDictionary?
#{ #"key1" : #"value1", #"key2" : #"value2", #"key3": #"value3" }
This may help you, try this.
NSDictionary *dict1 = [[NSMutableDictionary alloc] init];
NSArray *arr = [[NSArray alloc] initWithArray:<Parse the array here from RESTkit>];
for (int i = 0;i < [arr count], i++)
{
NSDictionary *dict = [arr objectAtIndex:i];
NSString *key = [dict objectForKey:#"key"];
NSString *value = [dict objectForKey:#"value"];
[dict1 setObject:value forKey:key];
}
NSLog(#" Dictionary %#", dict1);
[dict1 release];
I have a small doubt that is I have an NSArray which contains the following 4 objects:
Genesis, 1 Kings, leviticus, 2 Kings
I want to sort this array in dictionary order like i want an expected output like this
1 Kings, 2 Kings, Genesis, leviticus
How can this be achieved?
Go to this link:
https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Collections/Articles/Arrays.html#//apple_ref/doc/uid/20000132-SW5
This is Apple documentation and your problem is solved over there.
Check out the example.
//First create the array of dictionaries
NSString *last = #"lastName";
NSString *first = #"firstName";
NSMutableArray *array = [NSMutableArray array];
NSArray *sortedArray;
NSDictionary *dict;
dict = [NSDictionary dictionaryWithObjectsAndKeys:
#"Jo", first, #"Smith", last, nil];
[array addObject:dict];
dict = [NSDictionary dictionaryWithObjectsAndKeys:
#"Joe", first, #"Smith", last, nil];
[array addObject:dict];
dict = [NSDictionary dictionaryWithObjectsAndKeys:
#"Joe", first, #"Smythe", last, nil];
[array addObject:dict];
dict = [NSDictionary dictionaryWithObjectsAndKeys:
#"Joanne", first, #"Smith", last, nil];
[array addObject:dict];
dict = [NSDictionary dictionaryWithObjectsAndKeys:
#"Robert", first, #"Jones", last, nil];
[array addObject:dict];
//Next we sort the contents of the array by last name then first name
// The results are likely to be shown to a user
// Note the use of the localizedCaseInsensitiveCompare: selector
NSSortDescriptor *lastDescriptor =[[NSSortDescriptor alloc] initWithKey:last
ascending:YES
selector:#selector(localizedCaseInsensitiveCompare:)];
NSSortDescriptor *firstDescriptor =
[[NSSortDescriptor alloc] initWithKey:first
ascending:YES
selector:#selector(localizedCaseInsensitiveCompare:)];
NSArray *descriptors = [NSArray arrayWithObjects:lastDescriptor, firstDescriptor, nil];
sortedArray = [array sortedArrayUsingDescriptors:descriptors];
This code is an example from Apple documentation.
You can sort an array of NSString alphabetically like this:
NSArray *sortedArray = [myArray sortedArrayUsingSelector:#selector(caseInsensitiveCompare:)];
I create a dictionary with this data:
NSString *fileContentMap = [[NSString alloc] initWithContentsOfFile:MapPath];
SBJsonParser *parserMap = [[SBJsonParser alloc] init];
NSDictionary *dataMap = (NSDictionary *) [parserMap objectWithString:fileContentMap error:nil];
NSArray *MaparrayLongitude = [dataMap objectForKey:#"longitude"];
NSArray *MaparrayLatitude = [dataMap objectForKey:#"latitude"];
NSDictionary* DictionaryMap = [NSDictionary dictionaryWithObjects:MaparrayLatitude forKeys:MaparrayLongitude];
..then I read it with this code:
NSArray *allKeys2 = [DictionaryMap allKeys];
NSString *key2 = [allKeys2 objectAtIndex:i];
NSObject *obj2 = [DictionaryMap objectForKey:key2];
...but the keys are not ordered, and I want them to be ordered in the original order. How can I do this??
I tried to insert NSDictionary's in a NSMutableDictionary. There is no error but it won't work, it remains empty.
Here's my code:
NSMutableDictionary *einnahmen = [[NSMutableDictionary alloc] initWithCapacity:20];
NSArray *objects = [NSArray arrayWithObjects:
name,
[NSNumber numberWithInt: x],
[NSNumber numberWithInt: y],
[NSNumber numberWithInt: z],
nil];
NSArray *keys = [NSArray arrayWithObjects:
#"name",
#"startJahr",
#"zins",
#"entnahmefaehig",
nil];
NSDictionary *entry = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
[einnahmen setObject:entry forKey:#"name"]; //seems not to work
After [einnahmen setObject:entry the Debugger shows this:
I have solved this problem. The following code was in the wrong init-method:
NSMutableDictionary *einnahmen =
[[NSMutableDictionary alloc] initWithCapacity:20];
The compiler should show a error.
