是否可以将NSMutableArray保存到iOS中的磁盘上？如果是这样，您将如何处理？
我尝试了以下方法，但均未成功。
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* path = [documentsDirectory stringByAppendingPathComponent:@"test.plist" ];
[assets writeToFile:path atomically:YES];
我的NSMutableArray包含从ALAssetsLibrary中检索到的照片和视频的ALAsset，如下所示：
ALAssetsGroupEnumerationResultsBlock assetsEnumerationBlock = ^(ALAsset *result, NSUInteger index, BOOL *stop) { if (result) { [assets addObject:result]; } };
你可以做下面的事情
NSMutableArray *assets = [[NSMutableArray alloc] init];
NSMutableDictionary *aDict = [[NSMutableDictionary alloc] init];
[aDict setValue:@"Rajesh" forKey:@"Name"];
[aDict setValue:@"India" forKey:@"Country"];
[assets addObject:aDict];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* path = [documentsDirectory stringByAppendingPathComponent:@"test.plist" ];
[NSKeyedArchiver archiveRootObject:assets toFile:path];
NSMutableArray *assetsBack = [NSKeyedUnarchiver unarchiveObjectWithFile:path];
NSLog(@"%@", assetsBack);
