NSPredicate(format)

Predicate Format String Syntax, NSPredicate *predicate = [NSPredicate predicateWithFormat:@'%K like %@', attributeName, attributeValue]; The predicate format string in this case evaluates to firstName like 'Adam' . In the following example, the predicate format string evaluates to firstName like '%@' (note the single quotes around %@ ). Although it's common to create predicates directly from instances of NSComparisonPredicate, NSCompoundPredicate, and NSExpression, you often create predicates from a format string which is parsed by the class methods on NSPredicate. Examples of predicate format strings include: Simple comparisons, such as grade '7' or firstName like 'Shaffiq'

Case and diacritic insensitive lookups, such NSPredicate is a Foundation class that specifies how data should be fetched or filtered. Its query language, which is like a cross between a SQL WHERE clause and a regular expression, provides an expressive, natural language interface to define logical conditions on which a collection is searched.

NSPredicate, NSPredicate is a Foundation class that specifies how data should be fetched let namesBeginningWithLetterPredicate = NSPredicate(format: The format string supports printf-style format specifiers such as %x (see Formatting String Objects). Two important format specifiers are %@ and %K. %@ is a var arg substitution for an object value—often a string, number, or date. %K is a var arg substitution for a key path.

NSPredicate Swift

NSPredicate, While NSPredicate is incredibly powerful, it does come with a fair amount of downsides when used in Swift. First of all, since queries are written Instead of worrying about %@ conversions and then composing AND predicates, you can use the PredicatePal framework: let compound = * (Key('qIndex') qIndex && Key('formUUID') formUUID) Assuming that qIndex and formUUID are the correct type, Swift will automatically deduce the correct types for the Key objects.

Predicates in Swift, I've made that an optional NSPredicate because that's exactly what our fetch request takes: either a valid predicate that specifies a filter, or nil to mean 'no filter​.'. NSPredicate in Swift 3 Playground. The NSPredicate class is used to define logical conditions used to constrain a search either for a fetch or for in-memory filtering. when fetching objects, they arrive filtered from disk. This is used with Core Data; when the predicate is used in memory, we filter content of arrays

Examples of using NSPredicate to filter , NSPredicate is a Foundation class that specifies how data should be fetched Swift Objective-C. @objcMembers class Person: NSObject { let While NSPredicate is incredibly powerful, it does come with a fair amount of downsides when used in Swift. First of all, since queries are written as strings, they don’t come with any sort of compile-time safety — as there is no way for the compiler to validate our property names, or even verify that our queries are syntactically correct.

Availability. iOS 3.0+; macOS 10.4+; Mac NSDictionary can use predicates by filtering its keys or values (both NSArray objects). NSOrderedSet can either create new ordered sets from a filtered NSArray or NSSet, or alternatively, NSMutableSet can simply removeObjectsInArray:, passing objects filtered with the negated predicate. Using NSPredicate with Core Data

NSPredicate Cheatsheet, templated for predicate, checks if the value of key name is in a lot of methods that you can see here: http://nshipster.com/cfstringtransform/. Cocoa is the envy of other standard libraries when it comes to querying and arranging information. With NSPredicate, NSSortDescriptor, and an occasional NSFetchRequest, even the most complex data tasks can be reduced into just a few, extremely-understandable lines of code.

NSPredicate contains

NSPredicate, is a Foundation class that specifies how data should be fetched or filtered. Its query language, which is like a cross between a SQL WHERE clause and a regular expression, provides an expressive, natural language interface to define logical conditions on which a collection is searched. I normally would use the predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@'Any name CONTAINS[cd] %@',searchString]; But, if I search for John Lennon the predicate don't return anything, because it can't compare if it contains the characters John Lennon , since is missing the 1234 .

NSPredicate contains string lowercase, This is how I've solved my problem: if ((shopSearchBar.text != nil) && ([​shopSearchBar.text length] > 0)) { NSPredicate *predicate Predicates represent logical conditions, which you can use to filter collections of objects. Although it's common to create predicates directly from instances of NSComparisonPredicate, NSCompoundPredicate, and NSExpression, you often create predicates from a format string which is parsed by the class methods on NSPredicate.

NSPredicate Cheatsheet, returns an array containing the distinct objects in the property specified by the key path to the right of the operator. @unionOfObjects. returns the The CONTAINS predicate is part of the WHERE clause and supports searching for words and phrases in text columns. The CONTAINS predicate has features for matching words, matching inflectional forms of words, searching using wildcard characters, and searching using proximity.

NSPredicate SUBQUERY

NSPredicate with SubQuery, This can be done with a SUBQUERY clause. If myPlayer is the player in question: let predicate = NSPredicate(format:'SUBQUERY(games,$g, $g.player %@) SUBQUERY (collection_expression, variable_expression, predicate); where expression is a predicate expression that evaluates to a collection, variableExpression is an expression which will be used to contain each individual element of collection, and predicate is the predicate used to determine whether the element belongs in the result collection.

NSPredicate Cheatsheet, How subqueries work. SUBQUERY(collection, variableName, predicate). A subquery takes a collection then iterates through each object (as Predicates With Subqueries You’ve probably read that SQL is a language based on sets and predicates. Well, that sounds impressive but what does it really mean? It means that we ought to have some predicates that use sets as their operands.

[PDF] NSPredicate Cheatsheet, SUBQUERY(collection, variableName, predicateFormat). Subqueries. NSPredicate Cheatsheet. Presented by Realm: a mobile database that replaces. SUBQUERY (collection, variableName, predicate) A subquery takes a collection then iterates through each object (as variableName) checking the predicate against that object. It works well if you have a collection (A) objects, and each object has a collection (B) other objects.

NSPredicate ANY

[NSPredicate predicateWithFormat:@'ANY conditions.terrain %@', aTerrainObject]; that works fine, and returns any piece of advice where at least one of its conditions has that terrain type. However, when I try to do this, it fails:

I'm looking for a way to use NSPredicate to set a LIKE condition to fetch objects. In addition to that, an OR would be useful as well. I'm trying to do something where if a user searches 'James' I can write an NSPredicate that will do the equivalent of:

NSPredicate Cheatsheet, you would write a predicate like this: commitPredicate = NSPredicate(format: '​message 'I fixed a bug in Swift'). That means 'make sure the message attribute NSPredicate *predicate = [NSPredicate predicateWithFormat:@'%K like %@', attributeName, attributeValue]; The predicate format string in this case evaluates to firstName like 'Adam' .

NSPredicate boolean

I've got a boolean attr on an entity and the generated code for it is: @property (nonatomic, retain) NSNumber * countdownMode; @dynamic countdownMode; The entity is saved with: score.countdownMo

A class that represents an expression that, when evaluated, returns a boolean result.

To evaluate a predicate, you use the NSPredicate method evaluateWithObject: and pass in the object against which the predicate will be evaluated. The method returns a Boolean value—in the following example, the result is YES.
