How I can create a WHERE NOT IN condition by using NSPredicates?
I want to fetch all the records those are not already fetched by user.
Following Code solved my problem.
NSMutableArray *lodedRecords = [[NSMutableArray alloc] init];
[lodedRecords addObject:#"ali"];
NSPredicate *notInPredicate = [NSPredicate predicateWithFormat:#"NOT (firstName IN %#)",lodedRecords];
CKQuery *query = [[CKQuery alloc] initWithRecordType:recordType
predicate:notInPredicate];
CKQueryOperation *queryOperation = [[CKQueryOperation alloc] initWithQuery:query];

nsnumber *totaldur=0;
totalDur+=(NSNumber*)[dict valueForKey:#"tracktime"];
You can't perform addition on NSnumber for this
NSNumber * totaldur =[NSNumber numberWithInteger:20];
totaldur = [NSNumber numberWithInteger:([number1 integerValue] + [[dict valueForKey:#"tracktime"] integerValue])];
//// first of all convert both numbers to same data type like (nsinteger,int,float) and then apply addition on them and in the end save sum in nsnumber object
Hope it helps

I know setting a variable conditionally is valid:
someProperty = [anObject aFunctionThatReturnsBool]? #"Yes" : #"No";
This question has an answer that details the use of ternary statements in preprocessor macros
#define statusString (statusBool ? #"Approved" : #"Rejected")
and within a string formatting method
[NSString stringWithFormat: #"Status: %#", (statusBool ? #"Approved" : #"Rejected")]
But what about within any method?
[NSNumber numberWithInt:(aVariableThatCouldBeSet)? 100 : 0)];
And conditional method calling?
[anObject aFunctionThatReturnsBool]? [self doThis] : [self doThat];
Bonus points for any other uses not listed.

I want to check if an NSString ends with 19xx or 20xx, with the x's being any valid numbers.
How can I do this?
Sounds like a predicate with a regular expression fits your bill:
NSString *str = #"2013";
NSPredicate *yearPredicate = [NSPredicate predicateWithFormat: #"SELF MATCHES '(19|20)[0-9]{2}'"];
BOOL matched = [yearPredicate evaluateWithObject: str];

int *SliderMaximum = V1.TeamAmountAfterSave;
[sliderTeamSelect setmaximum:SliderMaximum];
I need to convert SliderMaximum to a float how do I do this?
NSNumber *yourNumber = [NSNumber numberWithInt: SliderMaximum];
float yourFloat = [yourNumber floatValue];
and you don't need a pointer to int, it's useless, computationally allocate a pointer and write inside address pointer to int is same as allocate a int and write int in it.
Have you tried multiplying it by a float?
CGFloat sliderMaximum = SliderMaximum * 1.0f;
[sliderTeamSelect setmaximum:[[V1.TeamAmountAfterSave] floatValue]];
