Question

我有点被阻止我有解析数据我可以下载数据现在我想用NSUserDefaults保存这些数据或者其他因为我需要一个数组因为某些原因我只能看到第一个数据而不是全部

[super viewDidLoad];
PFQuery *query = [PFQuery queryWithClassName:@"DataStaff"];
[query findObjectsInBackgroundWithBlock:^(NSArray *comments, NSError *error) {
    for (NSObject *comment in comments)
    {
        NSString *name = [comment valueForKey:@"name"];
         NSLog(@"%@",name);


        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        NSData *data = [NSKeyedArchiver archivedDataWithRootObject:name];
        [defaults setValue:data forKey:@"key"];

                    NSArray *array =@[@"%@",name];
                 [_textField setSuggestions:array];

您需要保存数组，然后使用NSUserDefaults构建NSMutableArray：

// Initiliaze data
NSMutableArray *data = [[NSMutableArray alloc] init];

// Retrieve data
PFQuery *query = [PFQuery queryWithClassName:@"DataStaff"];
[query findObjectsInBackgroundWithBlock:^(NSArray *comments, NSError *error)      {
    for (PFObject *comment in comments)
    {
        NSString *name = [comment valueForKey:@"name"];
        NSLog(@"%@",name);

        [data addObject:name];
    }

    // Save data
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:data forKey:@"key"];
    [defaults synchronize];
}];

将objectAtIndex解析为Array并保存NSUserDefaults
