在ios8.3中运行,但在ios9或10中运行没有这个问题.

解决方法
如果你看看崩溃报告,似乎Xcode 8有一些问题转换Swift方法CIContext(options:[String:Any]?)到它的Objective-C对应(CIContext *)contextWithOptions:(NSDictionary< NSString *,id> ; *)选项; 而是转换为 – [CIContext initWithOptions:],因此无法识别的选择器. 一个可能的解决方法是声明一个这样的Objective-C类:
@interface CIContext (Workaround) + (CIContext *)yourprefix_contextWithOptions:(NSDictionary<NSString *,id> *)options; @end
@implementation CIContext (Workaround) + (CIContext *)yourprefix_contextWithOptions:(NSDictionary<NSString *,id> *)options { return [CIContext contextWithOptions:options]; } @end
然后在您的模块桥接头中导入此类别,并将原始CIContext init调用替换为此类别中的一个.
我想象这是一个可以用Xcode更新修复的编译问题.在此期间,此解决方法可能会有所帮助.
