    Parameters

    string

    The string value.

  • Constructs Variant object from a list of values.

    Declaration

    Objective-C

    - (id)initWithArray:(NTVariantVector *)array;

    Parameters

    array

    The array of JSON values.

  • Constructs Variant object from a map of values.

    Declaration

    Objective-C

    Parameters

    object

    The map of JSON values.

  • Returns the type of this variant.

    Return Value

    The type of this variant.

  • Returns the string value of this variant.

    Declaration

    Objective-C

    - (NSString *)getString;

    Return Value

    The string value of the variant. If the variant is not string, empty string will be returned.

    Parameters

    idx

    The index of the array element to return (starting from 0).

    Return Value

    The array element at specified position or null type if the element does not exist or the variant is not an array.

  • Returns true if object elements contains the specified key.

    Declaration

    Objective-C

    - (BOOL)containsObjectKey:(NSString *)key;

    Parameters

    key

    The key of the object element to check.
