问题
I am supporting iOS8 and greater in my App. However, I cannot get passed this Image Asset warning. What file am I missing? See the below screenshot:
an iphone retina (4-inch) launch image for ios 7.0 and later is required
回答1:
You've suppled images for 4.7 and 5.5-inch devices but you need to have one for 4-inch devices as well (pre-iPhone 6).
You will need to select the checkboxes under "iOS 7 and later" (iPad ones if you're making an iPad app, iPhone one if iPhone app, all if Universal) at the right pane. These are used in both iOS 7 and 8.
