Property descriptions

ObjCException.ErrorNumber

ErrorNumber As Integer

Used to contain an error number that describes the runtime error.

ObjCException.Handle

Handle As Ptr

Allows you to get the underlying exception object (typically an instance of NSException).

ObjCException.Message

Message As String

Used to contain descriptive text to display when the runtime exception is encountered.

Method descriptions

ObjCException.Constructor

Constructor(message As String = "", errorCode As Integer = 0)

Note

Constructors are special methods called when you create an object with the New keyword and pass in the parameters above.

Used to raise your own RuntimeException with a message and optional error code.

ObjCException.Stack

Stack As String()

Returns a String array that contains a list of all of the methods in the stack from the main entrypoint to the point at which the exception was invoked.

The stack contains all the method names up and including the current method name.

This feature only works if the IncludeFunctionNames property on the App object is selected in the Shared Build Settings.

In addition to your own method calls, you will also see framework method calls, but these may not always be completely accurate due to insufficient symbols for the OS to resolve.

ObjCException.StackFrames

StackFrames As StackFrame()

Returns an array containing the stack when the exception was first raised.

Notes

If an Objective-C exception is raised due to an Objective-C Declare, it will be converted into a ObjCException object and raised through the normal exception system. ObjCException has a handle property, which allows you to get the underlying exception object (typically an instance of NSException).

Compatibility

All project types on all supported operating systems.
