CorePlots 不支持64位解决方案
摘录：
If you want a 64-bit version of Core Plot, you'll have to build a new version of the static library. Arm64 builds require iOS 7 but Core Plot supports earlier versions, too, so the pre-built library is 32-bit only.
Open CorePlot-CocoaTouch.xcodeproj and change the architecture settings to "Standard Architectures (including 64-bit)". Either build the "Universal Library" target and include the resulting static library in place of the one included with Core
Plot 1.4 or use the dependent project setup instead.
CGColorSpaceRef colorSpace = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB);
==> CGColorSpaceCreateDeviceRGB();
