Sorting NSDictionary which contains another dictionary - iphone

Question

I face the problem, when i sort the dictionary, i can't get output from this.
here i show my NSMutableDictionary which contains.
ReasonMst is my NSMutableDictionary.
Printing description of ReasonMst:
{
1 = {
nReasonNo = 1;
vReasonCode = 1;
vReasonDesc = "Office Purpose";
vReasonType = O;
};
10 = {
nReasonNo = 10;
vReasonCode = 10;
vReasonDesc = Transit;
vReasonType = O;
};
2 = {
nReasonNo = 2;
vReasonCode = 2;
vReasonDesc = Personal;
vReasonType = O;
};
3 = {
nReasonNo = 3;
vReasonCode = 3;
vReasonDesc = Specific;
vReasonType = O;
};
4 = {
nReasonNo = 4;
vReasonCode = 4;
vReasonDesc = "Meeting";
vReasonType = I;
};
5 = {
nReasonNo = 5;
vReasonCode = 5;
vReasonDesc = "Meeting arrange";
vReasonType = I;
};
6 = {
nReasonNo = 6;
vReasonCode = 6;
vReasonDesc = "NATIONAL CONFERENCE";
vReasonType = I;
};
7 = {
nReasonNo = 7;
vReasonCode = 7;
vReasonDesc = Other;
vReasonType = O;
};
8 = {
nReasonNo = 8;
vReasonCode = 8;
vReasonDesc = "Briefing Meeting";
vReasonType = I;
};
9 = {
nReasonNo = 9;
vReasonCode = 9;
vReasonDesc = "Meeting At HO";
vReasonType = I;
};
KeyList = (
1,
2,
3,
4,
5,
6,
7,
8,
9,
10,
""
);
}
i want to sort this NSMutableDictionary to vReasonDesc wise. Can any one tell me how can i do this easiest way ?

Answer 1

Suppose ReasonMst is your NSMutableDictionary, do this
NSArray *key=[[NSArray alloc]initWithArray:[ReasonMst objectForKey:#"KeyList"]];
NSMutableArray *vReasonDesc=[[NSMutableArray alloc]init];
NSMutableArray *sortedKeys=[[NSMutableArray alloc]initWithArray:nil];
NSDictionary *tempDict=[[NSDictionary alloc]init];
for (int i=0; i<[key count]; i++) {
[vReasonDesc addObject:[[ReasonMst objectForKey:[key objectAtIndex:i]]objectForKey:#"vReasonDesc"]];
}
[vReasonDesc sortUsingSelector:#selector(caseInsensitiveCompare:)];
for (int i=0; i<[vReasonDesc count]; i++) {
for (int j=0; j<[key count]; j++) {
tempDict=[ReasonMst objectForKey:[key objectAtIndex:j]];
NSLog(#"%# ... %#",[vReasonDesc objectAtIndex:i], tempDict);
if ([[tempDict objectForKey:#"vReasonDesc"]isEqualToString:[vReasonDesc objectAtIndex:i]]) {
[sortedKeys addObject:[tempDict objectForKey:#"vReasonNo"]];
}
}
}
NSLog(#"sdafa %#",sortedKeys);
sortedKeys contain the keys sorted according to your vReasonDesc values... now you can access your ReasonMst according to the keys in sortedKeys which inorder.
for (int i=0; i<[sortedKeys count]; i++) {
NSLog (#"%#",[ReasonMst objectForKey:[sortedKeys objectAtIndex:i]]);
}
