推荐答案

我想这样的东西会起作用（不太适合iphone的东西）：

I guess something like this would work (not very good at iphone stuff):

// Loading
NSString *path = ...
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:path];

// Manipulating
NSObject *newElement = ...
[array addObject:newElement];

// Storing
[array writeToFile:path atomically:YES];
