[allOrder.layersetBorderWidth:2];

CGColorSpaceRef colorSpaceRef =CGColorSpaceCreateDeviceRGB();

//CGColorRef color = CGColorCreate(colorSpaceRef, (CGFloat[]){1,0,0,1});

CGColorRef color =[UIColororangeColor].CGColor;

    [allOrder.layersetBorderColor:color];

 導航欄預設是半透明,讓view不要拓展到整個螢幕

self.edgesForExtendedLayout = UIRectEdgeNone;
 

讓tableView或者scorllerView從導航欄一下看下

self.automaticallyAdjustsScrollViewInsets = YES;
