之前只写过安卓保存图片到相册，iOS和安卓目前对于保存到相册的操作是很类似的，只不过是和Unity的交互方式是不一样的，废话不多说，下面上代码。
首先是头文件

// [!] important set UnityFramework in Target Membership for this file // [!] and set Public header visibility #import <Foundation/Foundation.h> // NativeCallsProtocol defines protocol with methods you want to be called from managed @protocol NativeCallsProtocol @required - (void) showHostMainWindow:(NSString*)msg; - (NSString*) getAppData:(NSString*)key; @end __attribute__ ((visibility("default"))) @interface FrameworkLibAPI : NSObject // call it any time after UnityFrameworkLoad to set object implementing NativeCallsProtocol methods +(void) registerAPIforNativeCalls:(id<NativeCallsProtocol>) aApi; @end @interface PhotoManager : NSObject - ( void ) imageSaved: ( UIImage *) image didFinishSavingWithError:( NSError *)error contextInfo: ( void *) contextInfo; @end |
接着是.mm文件

iOS的这个工具类也会持续更新。敬请期待！文章源自大腿Plus-https://www.zhaoshijun.com/archives/1737 文章源自大腿Plus-https://www.zhaoshijun.com/archives/1737
