我设置了sampleData数组的属性,如下所示:
@property (strong, nonatomic) NSArray *sampleData;
我希望这个数组的格式如下:
self.sampleData = @[ @{ @"createdAt": @"date A",
@"text": @"text A"
},
@{ @"createdAt": @"date B",
@"text": @"text B"
}
];
我的问题是实际数据来自 parse.com 数据库,我不知道如何以该格式将其保存到我的sampleData中。
以下是我到目前为止所做的事情,但仍缺少将数据从parse保存到sampleData数组的部分:
PFQuery *postQuery = [PFQuery queryWithClassName:kPAWParsePostsClassKey];
[postQuery whereKey:kPAWParseUserKey equalTo:[PFUser currentUser]];
[postQuery includeKey:kPAWParseUserKey];
postQuery.cachePolicy = kPFCachePolicyNetworkElseCache;
postQuery.limit = 20;
[postQuery findObjectsInBackgroundWithBlock:^(NSArray *myPosts, NSError *error)
{
if( !error )
{
NSLog(@"My Post --> %@", myPosts);
//self.sampleData = mySpotPosts; //this is definitely not right so need help here
}
}
];
这是NSlog输出:

if (!error) {...
的正文应该是:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MM/dd/yyyy hh:mm"]; // Set to whatever format you want your dates to be
NSMutableArray *objectArray = [NSMutableArray new];
for (PFObject *object in myPosts) {
[objectArray addObject:@{@"createdAt": [formatter stringFromDate:object.createdAt], @"text": [object objectForKey:@"text"]}];
}
self.sampleData = objectArray;
