我想在 AppDelegate 中存储两个用作全局数组的 NSMutableArray。这两个数组也存储在 NSUserDefaults 中。现在我想知道我必须如何创建这个文件以及如何在每次修改它们时存储这两个数组。你能帮助我吗？

Create an NSArray containing your two NSMutableArrays.
NSArray *array = [NSArray arrayWithObjects:<#(id), ...#>, nil];Write the array to a file.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); NSString *libraryDirectory = [paths objectAtIndex:0]; NSString *location = [libraryDirectory stringByAppendingString:@"/somefilename.plist"]; [array writeToFile:location atomically:YES];Load the array from the file.
NSString *path = [bundle pathForResource:@"file" ofType:@"plist"]; NSArry *array = (path != nil ? [NSArray arrayWithContentsOfFile:location] : nil);
创建一个包含两个 NSMutableArray 的 NSArray。
NSArray *array = [NSArray arrayWithObjects:<#(id), ...#>, nil];将数组写入文件。
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); NSString *libraryDirectory = [paths objectAtIndex:0]; NSString *location = [libraryDirectory stringByAppendingString:@"/somefilename.plist"]; [array writeToFile:location atomically:YES];从文件加载数组。
NSString *path = [bundle pathForResource:@"file" ofType:@"plist"]; NSArry *array = (path != nil ? [NSArray arrayWithContentsOfFile:location] : nil);
