When I built my game in xcode all the gui textures/texts look different

I put all these GUI textures and texts and they look the way I want in the editor but when I ran it on my iphone from xcode it looks so different. All the GUI Textures and Texts are in different sizes and places. Why did that happen? When I ran it on unity remote it's the same position and scale to the one in the editor but when I built in in Xcode and ran it on my iPhone all of it are in different places.
