I'm trying to filter a list of products from the json response. For the left side expression 'Status' right side i need a drop down. so i used right expression. While filtering this json using nspredicate its not working because of the space. Please help me to reach this.
NSArray *Mainarray;// Suppose this contains the response as "status"="Checked In" for 1 product and for other product "status"="Lost/Missing"
NSArray *left=@[[NSExpression expressionForKeyPath:@"status"]];
NSArray *right=@[[NSExpression expressionForKeyPath:@"Awaiting inputs"],[NSExpression expressionForKeyPath:@"Checked In"],[NSExpression expressionForKeyPath:@"Checked out"],[NSExpression expressionForKeyPath:@"Lost/Missing"],[NSExpression expressionForKeyPath:@"xxx Testing/Primary System"],[NSExpression expressionForKeyPath:@"Sold To"],[NSExpression expressionForKeyPath:@"closed"],[NSExpression expressionForKeyPath:@"Used for Parts"]];
NSArray *operators= @[@(NSEqualToPredicateOperatorType),@(NSNotEqualToPredicateOperatorType)];
NSArray *compoundTypes = @[@(NSAndPredicateType),@(NSOrPredicateType),@(NSNotPredicateType)];
NSPredicateEditorRowTemplate *template;
template=[[NSPredicateEditorRowTemplate alloc]initWithLeftExpressions:left rightExpressions:right modifier:NSDirectPredicateModifier operators:operators options:(NSCaseInsensitivePredicateOption | NSDiacriticInsensitivePredicateOption)];
compoundtemp = [[NSPredicateEditorRowTemplate alloc] initWithCompoundTypes:compoundTypes];
[predicateEditor setRowTemplates:@[template,compoundtemp]];
NSPredicate *predicate=[predicateEditor predicate];
NSArray *resultArray=[Mainarray filteredArrayUsingPredicate:predicate];
I am a little bit guessing (because I did not build a test project to verify this), but the "right hand sides" are constant values and not key paths. So you should replace
[NSExpression expressionForKeyPath:@"Awaiting inputs"]
by
[NSExpression expressionForConstantValue:@"Awaiting inputs"]
in NSArray *right=@[ ... ], and similarly for the other possible values.
