1.保存图片到相册
//image是要保存的图片
- (void) saveImage:(UIImage *)image{
if (image) {
UIImageWriteToSavedPhotosAlbum(image, self, @selector(savedPhotoImage:didFinishSavingWithError:contextInfo:), nil);
};
}
//保存完成后调用的方法
- (void) savedPhotoImage:(UIImage*)image didFinishSavingWithError: (NSError *)error contextInfo: (void *)contextInfo {
if (error) {
NSLog(@"保存图片出错%@", error.localizedDescription);
}
else {
NSLog(@"保存图片成功");
}
}
2.保存视频到相册
//videoPath为视频下载到本地之后的本地路径
- (void)saveVideo:(NSString *)videoPath{
if (_videoPath) {
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum([_videoPath path])) {
//保存相册核心代码
UISaveVideoAtPathToSavedPhotosAlbum([_videoPath path], self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
}
}
}
//保存视频完成之后的回调
- (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
if (error) {
NSLog(@"保存视频失败%@", error.localizedDescription);
}
else {
NSLog(@"保存视频成功");
}
}
