SetValueForKeyPath(IntPtr, NSString)
A constructor used when creating managed representations of unmanaged objects; Called by the runtime.
public void SetValueForKeyPath (IntPtr handle, Foundation.NSString keyPath);member this.SetValueForKeyPath : nativeint * Foundation.NSString -> unitParameters
- handle
- IntPtr
Pointer (handle) to the unmanaged object.
- keyPath
- NSString
Key-path to use to perform the value lookup. The keypath consists of a series of lowercase ASCII-strings with no spaces in them separated by dot characters.
Remarks
This constructor is invoked by the runtime infrastructure (GetNSObject(IntPtr)) to create a new managed representation for a pointer to an unmanaged Objective-C object. You should not invoke this method directly, instead you should call the GetNSObject method as it will prevent two instances of a managed object to point to the same native object.
Applies to
SetValueForKeyPath(NSObject, NSString)
Sets the value of a property that can be reached using a keypath.

- value
- NSObject
Value to set on the property.
- keyPath
- NSString
Key-path to use to perform the value lookup. The keypath consists of a series of lowercase ASCII-strings with no spaces in them separated by dot characters.
- Attributes
Remarks
The keypath is separated by dots, and each component is used to lookup a specific key on the object. The process is repeated on each returning object until the last element is processed.
If a component of the key path is not found, the method SetValueForUndefinedKey(NSObject, NSString) is invoked, and its default implementation raises an Objective-C exception. Subclasses can alter this behavior by overriding that method.
