I am using XMLReader to parse a xml response. I have converted the xml to a NSDictionary. Now i want to access the array named 'cTrx' inside the NSDictionary. This is my NSDictionary:
{
Envelope = {
Body = {
fRetrieveTransactionsforReversalResponse = {
fRetrieveTransactionsforReversalResult = {
pCellularNumber = {
text = 0825669995;
};
pResponseCode = {
text = 00;
};
pResponseMessage = {
text = Approved;
};
pTrx = {
cTrx = (
{
pCardHolderName = {
};
pReference = {
text = 140826121114;
};
pTransactionAccount = {
text = "364241****0016";
};
pTransactionDate = {
text = "8/26/2014 12:11:18 PM";
};
pTransactionID = {
text = 23;
};
},
{
"xsi:nil" = true;
}
);
};
};
};
};
};
}
Thanks.
You can access dictionary and array values with square brackets:
val = dictionary[#"key"];
item = array[i];
It works for nested dictionaries as well:
NSDictionary *nested = #{#"dict_key": dictionary};
dictionaryVal = nexted[#"dict_key"][#"key"];
So, in your case, you could access cTrx array in next way:
NSArray *cTrx = yourDictionary[#"Envelope"][#"Body"][#"fRetrieveTransactionsforReversalResponse"][#"pTrx"][#"cTrx"];
Long string of code :)

I am trying to get data from firebase database using firebase query
self.getReferencePath().child(User.followingReferencePath).queryOrderedByKey().queryLimited(toLast: 5)
When I pass this query to firebase and print the snapshot.value, I get the data in the order present in firebase as following
snapshot.value {
"-L2_hNtqB5UCBzgMFX0m" = {
"debate_id" = "-L2_hNtqB5UCBzgMFX0m";
};
"-L2_hSQSl7T5cDCfDoiV" = {
"debate_id" = "-L2_hSQSl7T5cDCfDoiV";
};
"-L2_h_vrwqID5Esl6gOk" = {
"debate_id" = "-L2_h_vrwqID5Esl6gOk";
};
"-L2_hfAruruMjzrLEZtI" = {
"debate_id" = "-L2_hfAruruMjzrLEZtI";
};
"-L2_hk2Uq7IBcflkO5YQ" = {
"debate_id" = "-L2_hk2Uq7IBcflkO5YQ";
};
}
But after converting the snapshot.all values as NSArray, the order changes as follow
let followingDbate = followingDebatesSnapshot.allValues as NSArray
print("followingDbate",followingDbate)
followingDbate (
{
"debate_id" = "-L2_hk2Uq7IBcflkO5YQ";
},
{
"debate_id" = "-L2_h_vrwqID5Esl6gOk";
},
{
"debate_id" = "-L2_hfAruruMjzrLEZtI";
},
{
"debate_id" = "-L2_hNtqB5UCBzgMFX0m";
},
{
"debate_id" = "-L2_hSQSl7T5cDCfDoiV";
}
)
I want to get the last Id as=nd pass it through another query. As the order changes I am not able to get the last id correctly. Please advice how to get the data without changing the order and also ow to get the last id from the snapshot I get. Thanks in advance
my server sends me an response in hierarchy way i do no how to grab the value from that
here my sample response :
{
id = "-1";
result = (
{
keyname = "Warranty Expiry Date";
value = "06-14-2017";
}
);
},
{
id = "-1";
result = (
{
keyname = Owner;
value = "";
}
);
},
{
id = "-1";
result = (
{
keyname = Model;
value = "";
}
);
},
{
id = "-1";
result = (
{
keyname = "Price $";
value = 1000;
}
);
},
{
id = "-1";
result = (
{
keyname = Vendor;
value = "";
}
);
},
{
id = "-1";
result = (
{
keyname = "Purchase Date";
value = "";
}
);
}
)
here is sample Java code how they extracted the values
Hashtable htAttrs = (Hashtable) editedAttrHash.get(assItmId);
if (htAttrs != null) {
Set<String> keys = htAttrs.keySet();
for (String deAttr : keys) {
xmlSerializer.startTag("", "attribute");
xmlSerializer.attribute("", "keyname", deAttr);
xmlSerializer.attribute("", "value",
htAttrs.get(deAttr).toString());
xmlSerializer.endTag("", "attribute");
}
}
i need to do no how to from this structure past one day i am blocked here anyone can fix my problem
How to extract values from nsmutablearray?If it is really nsmutablearray object, then extract the values is simple.
For example, to get id of first element:
NSString firstId = response[0][#"id"]
But it seems, like for now, it is just a json object. So, you should serialize it to nsarray object first.
I have the code below which has ben spat out of an XML parse but i'm unsure as to what I should do to consolidate it. How would I add all the 'string' items into an array??
Parser:
NSData *data=[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://www.url.net/directory/%#",fileName]]];
NSDictionary *dict=[XMLParser dictionaryForXMLData:data error:nil];
NSLog(#"%#",dict);
XMLParser is a custom class.
NSLog:
plist = {
dict = {
key = (
{
text = "\n\n\tmapFile";
},
{
text = "\n\tmapPreviewFile";
},
{
text = "\n\tmapScale";
},
{
text = "\n\tmapper";
},
{
text = "\n\tterrain";
},
{
text = "\n\tTopLeft";
},
{
text = "\n\tTopRight";
},
{
text = "\n\tBottomLeft";
},
{
text = "\n\tBottomRight";
}
);
string = (
{
text = "\n\thttp://www.url.com";
},
{
text = "\n\thttp://www.url.com";
},
{
text = "\n\t1 : 2 500";
},
{
text = "\n\tSeb O'H (2014)";
},
{
text = "\n\tUrban (school)";
},
{
text = "\n\t42.87067222225,147.31143055";
},
{
text = "\n\t42.8645138888888894, 147.3160527777777";
},
{
text = "\n\t42.87067222222222, 147.3160527777777";
},
{
text = "\n\t42.8645138888888894, 147.31143055555555";
}
);
text = "\n";
};
text = "\n";
version = "1.0";
};
I've tried many methods but still can't seem to get it working. So in simple my question is, how do I put a row in an NSDictionary into an NSArray.
Thanks.
You can simply filter the array using valueForKeyPath
NSArray *text = [data valueForKeyPath:#"plist.dict.string.text"];
I am currently using the Graph API to retrieve the News Feed for a user. However, some Posts of type "update" do not return any info on the original post e.g. in the result extract posted below, the story is "Joubert Nel commented on a link", but there is no info included as to what the link is, or the picture that goes with it. How can I obtain this info please?

is the link posted by Joubert? or using app you have permission. sounds like you don't have permission to post(link) but u have permission to Joubert activities
I'm using the following function in order to get all the keys and values of the preferences.plist file located in: /private/var/preferences/SystemConfiguration/preferences.plist
- (void)FindKeysAndValuesInPlist:(id)object forKeyNamed:(NSString *)keyName{
if ([object isKindOfClass:[NSDictionary class]])
{
NSLog(#"%#",keyName);
[object enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL *stop) {

}];
}
else if ([object isKindOfClass:[NSArray class]])
{
[object enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[self FindKeysAndValuesInPlist:obj forKeyNamed:nil];
}];
}
else
{
NSLog(#"%#.%#", keyName, object);
}
}

The problem is that I'm trying to create this kind of output format: MAINKEY.SUBKEY.VALUE
For example:
NetworkServices = {
"014226AB-75B7-41CF-9B96-48E82FD6A395" = {
Interface = {
DeviceName = ip4;
Hardware = "com.apple.CommCenter";
Type = "com.apple.CommCenter";
UserDefinedName = "com.apple.CommCenter (ip4)";
};
Would be: NetworkServices.014226AB-75B7-41CF-9B96-48E82FD6A395.Interface.Hardware.ip4
Iterate over the keys in a dictionary. When the value for a key is another dictionary, push the key onto a stack and recurse on the dictionary value. When the value is a string or number, then concatenate the keys in the stack and print the key path and value.
Code:
+ (void)printDict:(NSDictionary *)dict keyStack:(NSArray *)keys
{
if (keys == nil) {
keys = [NSArray array];
}
for (id key in dict) {
id value = dict[key];
if ([value respondsToSelector:#selector(objectForKey:)]) {
[self printDict:value keyStack:[keys arrayByAddingObject:key]];
} else {
NSLog(#"%# = %#", [[keys arrayByAddingObject:key] componentsJoinedByString:#"."], value);
}
}
}
