How to add NSDictionary of dictionaries to NSArray? - iphone

Question

I have a dictionary of dictionaries. This is the structure of my main dictionary:
The content of dictionary(
{
mondaysSales= {
totalSale = "1234.99";
},
tusdaySales= {
totalSale = "1234.99";
},
wednesdaySale={
totalSale = "1234.99";
},
thursdaySale{
totalSale = "1234.99";
},
fridaySale{
totalSale = "1234.99";
}
)
but I want to add each day with the day key to a array. For example:
this would be one of the entries of the array:
fridaySale{
totalSale = "1234.99";
}
Any of you how can accomplish this?, I'll really appreciate your help.

Answer 1

You can loop through the dictionary and add it to the array. Note that dictionaries are not sorted and you probably won't end up with a correct order for your weekdays
NSMutableArray *array = [#[] mutableCopy]
for (NSString* key in dictionary) {
id value = [dictionary objectForKey:key];
[array addObject:value];
}

Answer 2

Why not create a new object type and add that to the array?
StorageObject.h:
#interface StorageObject:NSObject
#property (nonatomic, retain) NSString *day;
#property (nonatomic, retain) NSString *saleType;
#property (nonatomic, retain) NSNumber *saleValue;
#end
StorageObject.m:
#implementation StorageObject
#synthesize
day = _day,
saleType = _saleType,
saleValue = _saleValue;
- (void)dealloc
{
[_day release];
[_saleType release];
[_saleValue release];
[super dealloc];
}
#end
Now just loop through your NSDictionary using:
for(NSString *key in [dictionary1 allKeys])
{
NSDictionary *innerDictionary = [dictionary1 objectForKey:key];
}
For every dictionary returned in that loop, instantiate your custom storage object and add it to the array.

I figure out solution:
NSMutableDictionary *tempDict=[[NSMutableDictionary alloc]init];
[tempDict setObject:[mainDic objectForKey:key] forKey:key];
[myArray addObject:tempDict];

Answer 4

Assuming you have a dictionary of dictionaries:
You can do
NSMutableArray *list = [#[] mutableCopy];
for (NSString *key in [mainDictionary allKeys]) {
NSDictionary *dict = #{
key : [mainDictionary objectForKey:key],
};
[list addObject:dict];
}

There is an easy way to do this just don't create an NSDictionary and instead create an NSArray, by doing the following
NSArray *Array = #[#{#"friday sale, totalSale" : #"1234.99"}]
Or if you want to have specifics gotten from anything else in it.
NSInteger value = 1;
NSArray *Array = #[#{ #"Friday sale, totalSale" : [NSString stringWithFormat:#"%ld", (long)value]}];
Then you get this value from simply saying,
NSString *somestring = Array["Friday sale, totalSale"];
