        are you sure it is working fine after setting QT_PLUGIN_PATH to point to your bundle plugin path , I
        This is my QT_PLUGIN_PATH, but my app is yet to be launched.
        //////////////////////////////////////////////////////////////////

          you can try with:
          @ export QT_PLUGIN_PATH=/Users/username/Downloads/1Checker.app/Contents/PlugIns/
          @
          then
          @
          ./1Checker.app/Contents/MacOS/1Checker
          @

          I have three warnings about QEventLoop but I can see your application login screen

            This application failed to start because it could not find or load the Qt platform plugin "cocoa".

            Available platform plugins are: cocoa, minimal, offscreen.

            Reinstalling the application may fix this problem.

              If you rename your Qt folder does it also fail ?

                I have tried these:

                1. set QT_PLUGIN_PATH and rename Qt folder, succeed to launch it with terminal, but failed by double clicking.

                2. set QT_PLUGIN_PATH and do not rename Qt folder, both failed.

                3. do not set QT_PLUGIN_PATH and rename Qt folder, both failed.

                so I think even if I set QT_PLUGIN_PATH, the reference pointing to the Qt folder is the preference.

                  Are you using QDir::currentPath ?

                    no, but the following code has been added to main.cpp already,

                    @int main(int argc, char *argv[])
                    {

                    QApplication a(argc, argv);
                    
                    QDir dir(QCoreApplication::applicationDirPath());
                    qDebug()<<dir.absolutePath();
                    dir.cdUp();
                    qDebug()<<dir.absolutePath();
                    dir.cd("PlugIns");
                    qDebug()<<dir.absolutePath();
                    QApplication::setLibraryPaths(QStringList(dir.absolutePath()));
                    qDebug()<<QCoreApplication::libraryPaths();@
                    

                    and the relevant application output

                      Also, Here is another important clue,
                      @This application failed to start because it could not find or load the Qt platform plugin "cocoa".@
                      maybe the reference pointing to the platform plugin in the bundle is broken, and QCoreApplication::libraryPaths() is not used to search for platform plugins , as" what he said":https://bugreports.qt-project.org/browse/QTBUG-29503

                        Can you build Qt from sources and use this one to create your application ? I didn't have that problem with a current git build

                          Actually,I got stuck when I tried to build Qt from source. Particularly, they were some errors about webkit...I am trying to solve it.

                            I followed these steps again:
                            1)git clone git://gitorious.org/qt/qt5.git qt5
                            2) cd qt5
                            3) ./init-repository
                            4) ./qtrepotools/bin/qt5_tool -p
                            5) .........

                            but got this at step 4,

                            Entering 'qtactiveqt'

                                  Do you mean, the source tar.gz or from git ?

                                    The former, the problem is still there when I try to git.

                                      Provisional measures :
                                      adding the following code to main.cpp (before QApplication a(argc, argv));

                                      I think the path of loading plugins has to be loaded before running QApplication a(argc, argv);
                                      @int main(int argc, char *argv[])
                                      {
                                      QString path = QString(argv[0]);
                                      QString end = path.split("/").last();
                                      path.remove(path.length() - end.length(), end.length());
                                      QDir dir(path);
                                      dir.cdUp();
                                      dir.cd("PlugIns");
                                      QApplication::setLibraryPaths(QStringList(dir.absolutePath()));
