无法从iOS的PHAssets中的/ var / mobile / Media / PhotoData / Sync / 100SYNCD /文件夹访问媒体文件吗?

问题描述 投票:0回答:1

我已经使用CTAssetsPickerController库访问iOS照片。我已将照片从MAC通过iTunes同步到iPhone,并且照片在“我的Mac”中在我的手机库中提供。但是,当我从选择器中选择资产时,在资产信息中,我得到的文件URL为file:///var/mobile/Media/PhotoData/Sync/100SYNCD/IMG_0002.JPG,并且从给定的URL中找不到数据]

  **PHAsset *asset = [self assetAtIndexPath:indexPath];
            if (asset.mediaType == 1) {
                if (@available(iOS 9.0, *)) {
                    NSArray *arr = [PHAssetResource assetResourcesForAsset:asset];
                    if (arr) {
                        PHAssetResource *resource = arr.firstObject;
                        if (resource) {
                            NSUInteger fileSize = [[resource valueForKey:@"fileSize"] integerValue];
                            NSLog(@"size %lu",(unsigned long)fileSize);
                            if (fileSize < self.picker.maxLimitSize) {
                                [self.picker selectAsset:asset];
                                dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
                                    [[PHImageManager defaultManager] requestImageDataForAsset:asset options:nil resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
                                        NSURL *fileURL = [info valueForKey:@"PHImageFileURLKey"];
                                        NSData *imagedata = [NSData dataWithContentsOfURL:fileURL];
                                        [self.picker addURL:fileURL atIndex:self.selectedAssetsCounts];
                                        ++self.picker.selectMediaFiles;
                                    }];
                                });
                            }else{
                                [self showAlertMessageWithTitle: CTAssetsPickerLocalizedString(@"sizelimitexceed", nil) andMessage:CTAssetsPickerLocalizedString(@"mediasizelimitmessage", nil) withIndex:indexPath];
                            }
                        }
                    }**
