Cant get the PFObject from this cloud code using iOS SDK - ios

Question

I have a cloud code on Parse.com searching a PFObject and returning it on the basis of date created the code is as follows
Parse.Cloud.define("getJournalEntry", function(request, response) {
var currDate = request.params.currDate;
var d1 = new Date(currDate + 1000 * 60 * 60 * 24 * 1); // gets 7 days ago
var query = new Parse.Query("JournalEntry");
query.greaterThan("createdAt",currDate);
query.lessThan("createdAt",d1);
query.find({
success: function(results) {
var entry = results[0];
response.success(entry);
},
error: function() {
response.error("no entry found");
}
});
});
I am trying to invoke this code from iOS app as follows
NSDate *dateOfMonth = .....;// some calculations
[PFCloud callFunctionInBackground:#"getJournalEntry"
withParameters:#{#"currDate": dateOfMonth}
block:^(PFObject *entry, NSError *error) {
if (!error) {
NSLog(entry[#"text"]);
}
else
{
NSLog(error.description);
}
}];
When checked this code from console if I supply wrong date it returns expected reply but in iOS it always crashes with following error
2014-07-16 18:18:44.343 Emojo[2845:60b] -[NSNull objectForKeyedSubscript:]: unrecognized
selector sent to instance 0x27f3068
2014-07-16 18:18:44.345 Emojo[2845:60b] *** Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[NSNull objectForKeyedSubscript:]: unrecognized selector
sent to instance 0x27f3068'
What can be the issue ?
I this will happen even on sending correct date or wrong date.

Try this may be helpfull
Updated
NSDate *dateOfMonth = [NSDate date];
NSDateFormatter *dateformat = [[NSDateFormatter alloc]init];
[dateformat setDateFormat:#"dd-MM-YYYY"];
NSMutableDictionary *dateOfMonthDic = [[NSMutableDictionary alloc]init];
[dateOfMonthDic setValue: [dateformat stringFromDate:dateOfMonth ] forKey:#"currDate"];
[PFCloud callFunctionInBackground:#"getJournalEntry"
withParameters:dateOfMonthDic
block:^(PFObject *entry, NSError *error) {
if (!error) {
NSLog(entry[#"text"]);
}
else
{
NSLog(error.description);
}
}];
Thanks & Cheers ..
