Xamarin.Mac 1.4

Xamarin.Mac 1.4.22

What's New?

  • Added bindings for NSComboBoxCell and NSComboBoxCellDataSource .
  • Fixed a regression where NSApplication.EndSheet would crash when attempting to invoke the NSAction passed to a corresponding NSApplication.BeginSheeet call.
  • Fixed 12597 , preventing a crash when a managed method returns a null string to the native runtime, such as in NSComboBoxDataSource.CompletedString .
  • Fixed 12529 , preventing a crash when setting an NSMenuItem.Activated delegate.
  • Fixed 12712 , avoiding a crash in CGPath.EllipseFromRect .
  • Added CMSampleBuffer.GetSampleTimingInfo and CMSampleBuffer.CreateWithNewTiming to allow adjusting the time of CMSampleBuffer s.
  • Added linker support to preserve types using XML serialization and data contracts attributes.

Samples

Xamarin.Mac 1.4

The focus of this release was on providing strongly-typed notifications for the AppKit framework, the introduction of three low-level C API bindings, and general bug fixing.

You can check our Roadmap to learn where Xamarin.Mac is headed.

Highlights

AppKit Strongly-Typed Notifications

Full coverage and support for strongly-typed notifications has been introduced for the AppKit framework. These provide a code-completion-friendly API design for accessing dictionary entries on notifications through strong typing.

CFPreferences

"High-Level" app+user focused APIs for CFPreferences have been introduced. CFPreferences is in the CoreFoundation framework and is wrapped by the higher-level NSUserDefaults in the Foundation framework.

Typically NSUserDefaults is preferred, but CFPreferences can be useful for lower-level operations. CFPreferences is thread safe.

NetworkReachability and CaptiveNetwork

The SystemConfiguration framework's NetworkReachability and CaptiveNetwork APIs are now supported.

NetworkReachability allows an application to determine the status of a system's current network configuration and the reachability of a target host.

CaptiveNetwork allows an application to interact with Captive Network Support, the system component responsible for detecting networks that require user interaction before providing internet access, such as those typically found at WiFi hotspots in public locations such as airports and hotels.

HTML Forms in WebKit

The WebKit framework coverage was expanded to include DomHtmlFormElement and DomHtmlTextAreaElement to allow fully interacting with HTML forms from C#. Additionally, DomHtmlInputElement now includes a Files property exposing a DomFileList for supporting input[type=file] elements.

Native Exception Marshalling

General support for marshalling native Objective-C exceptions ( NSException) has been introduced to on APIs annotated with [MarshalNativeExceptions]. Currently only a few APIs known for throwing recoverable native exceptions support this feature:- MonoMac.CoreBluetooth.CBUUID.FromString .

  • All MonoMac.AppKit.NSColor.<strong>*</strong>Component properties.
  • MonoMac.Foundation.NSKeyedUnarchiver : its constructor and UnarchiveObject and UnarchiveFile methods.

If other APIs become known to be both problematic and recoverable, they can be annotated in the future. Please let us know.

For more details, see the Binding Types Reference Guide. Native NSException objects will be wrapped in a managed ObjCException which can be caught.

Other Notable Fixes and Changes

  • MonoMac.Foundation.NSOrderedSet and MonoMac.Foundation.NSMutableOrderedSet were added.
  • Stock template images are now supported through the new NSImageName enum to be used in NSImage.ImageNamed(NSImageName) .
  • Fixed bundling native libraries where some used absolute paths for their dependencies. This previously broke when the Mono runtime was absent on the target system. #11351 .
  • Fixed issues when referencing mixed-mode (e.g. C++) .NET assemblies. #11448 .
  • Added support for bundling internationalized assemblies even if the linker is disabled.
