invoke framework in termimal the window seems to be blocked - objective-c

Question

now ,I have a framework named "MyFramework.framework" which include a window.nib, and I write a example to invoke it in terminal.
code:
//<MyFramework/myUI.h>
#ifndef Frmwork_myUI_h
#define Frmwork_myUI_h
#ifdef __cplusplus
extern "C"{
#endif
void ShowDialog();
#ifdef __cplusplus
}
#endif
#endif
//test.mm
#include <MyFramework/myUI.h>
#include <Foundation/NSRunLoop.h>
int main(int argc, char *argv[])
{
ShowDialog() ;
while (!isTransmitCompleted)
{
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
}
return 0;
}
//build test.mm
g++ -c test.mm -o test.o
g++ test.o -o test -lpthread -framework Cocoa -framework AppKit -framework CoreData -framework Foundation -framework MyFramework
//run
$./test
the Dialog can appear, but it seems be blocked ,it has no focus , I can not input anything, I can do nothing ,what is wrong?

Answer 1

now , I got the solution.
In OS X 10.6 ,I write a npapi plugin for Safari, In this plugin I invoke an framework which shows a Modal Window to get password. after close this modal window ,the Safari seems to block.
In my framework , I show this modal window by runModalForWindow function ,when I change to runModalSession , everything works perfectly. I don`t know why but it really works for me .
