Crash coming on using Embeddinator 4000 iOS Framework inside Obj-C Framework.

[amitkhoth]

1)I have a host App and a Obj-c framework inside workspace.

2) I am using Embeddinator 4000 iOS framework(HelloSharedUI.iOS.framework) inside Obj-c framework.

3) Crash is coming when I call func of HelloSharedUI.iOS.framework (Embeddinator)From Obj-c FrameWork.

Crash in this function

• (IBAction)launchXamarin:(id)sender { HelloSharedUI_UIHelpers *helpers = [[HelloSharedUI_UIHelpers alloc] init]; //Crash Here [helpers showMyPageText: @"Hi"]; }

crash Log

MonoTouch: Could not install sigaction override, unexpected sigaction implementation.

HostApp[96001:1415276] The assembly mscorlib.dll was not found or could not be loaded.

HostApp[96001:1415276] It should have been installed in the `/Users/builder/jenkins/workspace/xamarin-macios/xamarin-macios/external/mono/sdks/out/ios-sim64-release/lib/mono/2.1/mscorlib.dll' directory.

This is Native call from Obj-c Framework.

import "ViewController.h"

import "HelloSharedUI.iOS/HelloSharedUI.iOS.h"

@implementation ViewController

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. }
• (IBAction)launchXamarin:(id)sender { HelloSharedUI_UIHelpers *helpers = [[HelloSharedUI_UIHelpers alloc] init];//crash [helpers showMyPageText: @"Hi"]; }

There are many moving pieces in setting up hosting. Many are easy to get wrong, and it can be difficult to reproduce the same failure state.

I appreciate the steps to reproduce, but could you post a sample application showing your setup?

[amitkhoth]

1. create a Obj-c Workspace in Xcode.

2. add(File-> new -> project->single View App) a single view Obj-c application in this workspace call it Host App.

3. then Add (File->New -> project -> cocoa Touch framework) in same workspace(This is . Framework Project) call it Native Framework.

4. Embed this Native framework in Host App.

5. I have Embeddinator 4000 .framework created from Xamarin Studio call it shared.framework.

6. Embed this shared.framework in Native Framework.

Steps to reproduce:

a) in Host App I have a button in storyBoard(view) file that launches Native FrameWork View.

b) in Native FrameWork View(.stroyboard viewcontoller) I have other Button that launches Xamarin view using shared.Framawork.

Call From Native framework to shared Framework(E4k)

import "ViewController.h"

import "HelloSharedUI.iOS/HelloSharedUI.iOS.h"

@implementation ViewController

(void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. } (IBAction)launchXamarin:(id)sender { HelloSharedUI_UIHelpers *helpers = [[HelloSharedUI_UIHelpers alloc] init];//crash [helpers showMyPageText: @"Hi"]; } @EnD

So your steps leave out a number of steps, like what does this entail?

I have Embeddinator 4000 .framework created from Xamarin Studio call it shared.framework.

What settings did you use, command line invocation, etc?

Please consider attaching a zip file of a sample project.
