i have added a splash screen to my application by adding Default.png. the splash screen works fine in the simulator but not showing on real device
回答1:
Check the case of the file name.
Default.png, default.png, Default.PNG and DEFAULT.png are all different files on the device, but not in the simulator.
回答2:
The file name must be Default.png (with a capital D). Also, do a clean/rebuild of the entire project to ensure the most recent version of the file is being included in the project.
回答3:
Make a "Default.png" file (with a capital "D"). Then clean all targets and build again.
回答4:
Sometimes this issue hapens, when .png file was renamed from .jpg file. So, for example, you had image.jpg, you've renamed in to image.png, and using this image.png. It'll be correctly displayed in simulator, and won't work on device
回答5:
Make sure the name of the file begins with a capital "D", then clean and rebuild.
回答6:
Select your Default.png in the groups and files window and make sure in the file listing above the editor window that the checkbox on the far right is checked. Without this the file will not be copied to the application bundle after compilation is finished.
