Displaying iOS Launch Images


  • I am trying to get my launch image to display on my app, with no success. I cannot find up-to-date information on the proper way to do this in Qt. Here is my .plist file:

    The icons are working just fine but no launch images. Here is my project file:

    include(../top_srcdir.pri) # defines top-level source trees
include(../ace_path.pri)

CONFIG += c++11 link_prl

SETTINGS_BUNDLE_DATA_ROOT.files += Root.plist
SETTINGS_BUNDLE_DATA_ROOT.path = Settings.bundle
SETTINGS_BUNDLE_DATA_LANG.files += Root.strings
SETTINGS_BUNDLE_DATA_LANG.path = Settings.bundle/en.lproj
QMAKE_BUNDLE_DATA += SETTINGS_BUNDLE_DATA_ROOT SETTINGS_BUNDLE_DATA_LANG

ios {
    QMAKE_INFO_PLIST = tap_display.plist
    ios_icon.files += $$files($$PWD/ios/icons/*.png)
    launch_image.files += tap_display_launch_screen.xib $$files($$PWD/ios/launch-images/*.png)
    QMAKE_BUNDLE_DATA += ios_icon launch_image
}

QT += qml quick
INCLUDEPATH += $$aop_util_includes \
              $$aop_logger_includes \

SOURCES += $$files(*.cpp)
OBJECTIVE_SOURCES += $$files(*.mm)

HEADERS += $$files(*.hpp) \
           $$files(*.h)

RESOURCES += qml.qrc

macx {
  DEFINES += IOS_BUILD
}

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Default rules for deployment.
include(deployment.pri)

#target link libraries
include(../tap_data.pri) # defines tap_data library
include(../tap_messaging.pri) # defines tap_messaging library
include(../aop_interface.pri)
include(../TableLookups.pri)
include(../WindModel.pri)

    The icon files, my .XIB file and my launch image files are all getting copied into the bundle, but again, while the icons work, the launch images do not. All I get is the default screen which displays the app name. I set the deployment target to iOS 7 or greater with no luck, as well as creating my own .XIB file (which I copied from the original). Still no luck.

    Do I need to manually modify the .XIB to incorporate these launch files?

    I would appreciate any help

    You need to specify your xib in In your .plist:

    <key>UILaunchStoryboardName</key>
<string>tap_display_launch_screen</string>

  • @TioRoy It is there already. Its way at the bottom of the .plist file I posted. The question is, what changes do I need to make to the .xib file?

    It's duplicated.

  • @TioRoy Ah yes! I got rid of the duplicate, but its still the same issue. I am guessing that the .xib is not properly formed, but I don't know how to add the launch images to the .xib

  • @DRoscoe , Unfortunately, you need to edit XIB files with XCode.

  • @TioRoy OK, so I need to figure out how to do this in xCode and then capture the resulting .xib file and incorporate it into my .pro file?

  • Ok, I figured out how to get the images in the XIB. I created a view for each image. It took me a while to figure out I could drag those objects from the lower right corner onto the launch screen view.

    I can't seem to get the app to figure out which image and orientation to use, so I either added it incorrectly and the app cannot determine it, or I still need to tweak it a bit

    If you are using shadow build, you will open XCode project from build directory. So, when you edit .XIB files, you need to copy the .XIB file from build directory to your source directory.

  • Note that iOS has a bug where it caches old launch screens
