Set the app's startup picture (Launch image)

Step1

• 1. Click Image.xcassets to go to image management, then right click, pop Up "New Launch image"
• 2. The right-hand tick allows you to choose whether you want to support ipad, crossbar, vertical screen, and the lower version of iOS. I chose Ios8.0,ios7.0,ios6 this way. No support.

Step2

Drag the specified size picture from your file into the fixed position.

System	Size	Resolution
iOS8	Retina HD5.5	1242x2208
	Retina HD4.7	750x1334
	Landscape Retina Hd 5.5	2208x1242
iOS7		640x960
	Retina4	640x1136

Step3

Click your entire project name and select General, that's it.

I completed the above steps, and set the launch Images srouce for Launchimage, but the start picture is still the same, and later found launch Srceenfile, this inside set up, go to see, Your directory has a file called Launchscreen.xib Open the Right box, select the file, and then, the use as launch Srceen canceled, this is the reason you have been set launch image is not successful
