赞:

//create array
NSMutableArray *arr = [[NSMutableArray alloc] init];

//Add data
[arr addObject:@"some object"];

//String Path of file
NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

//Save
[arr writeToFile:path atomically:YES];

以后像这样加载它:

//Load it
NSMutableArray *arr = [[NSMutableArray alloc] initWithContentsOfFile:path];
