在ios8.3中运行,但在ios9或10中运行则没有此问题。

最佳答案
如果查看崩溃报告,似乎Xcode 8在将Swift方法CIContext(options: [String : Any]?)
转换为其与Objective-C对应的+ (CIContext *)contextWithOptions:(NSDictionary<NSString *,id> *)options;
时会遇到一些问题。
而是将其转换为-[CIContext initWithOptions:]
,因此无法识别的选择器。
一种可能的解决方法是声明一个Objective-C类别,如下所示:
@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
然后将此类别导入模块桥接头中,并用该类别中的那个替换您原来的CIContext init调用。
我想象这是一个编译问题,可以通过Xcode更新来解决。同时,此替代方法可能会有所帮助。
