如何为NSString drawAtPoint设置上下文？ [英] how to set a context to NSString drawAtPoint?

问题描述

我目前正在封装许多 [NSString drawAtPoint：withFont：] 函数调用的方法，以便我可以通过一次调用绘制许多字符串，但是如何我告诉方法在哪里画这些线？

I currently working on encapsulation many [NSString drawAtPoint:withFont:] function calls to a method so that I could draw lots of strings by a single call, but how can I tell the method where to draw these strings?

如果我将 CGContextRef 传递给它怎么办，如何设置 CGContextRef 作为当前上下文？

What if I pass a CGContextRef to it, how to set a CGContextRef as current context?
