MarshalObjectiveCExceptionMode
Fields
| Name | Value | Description |
|---|---|---|
| Default | 0 | The default mode. This is currently the same as ThrowManagedException. |
| UnwindManagedCode | 1 | Let the Objective-C runtime unwind managed frames. This option is not recommended, because it leads to undefined behavior (the app may crash, leak memory, deadlock, etc.) if Objective-C exceptions are thrown (the Objective-C runtime does not know how to unwind managed frames, so anything can happen). The recommended option is ThrowManagedException. |
| ThrowManagedException | 2 | Convert the Objective-C exception to a managed exception. This is the recommended option (and also the default behavior). |
| Abort | 3 | Abort when an Objective-C exception reaches managed code. This may be useful during debugging to easily detect when Objective-C exceptions are thrown. |
| Disable | 4 | Disable marshalling Objective-C exceptions. This is effectively the same as UnwindManagedCode, except that no events will be raised. |
