基本Parse.com查詢正在緩存,但我無法緩存這個特定的查詢,我已經跑了很多次,因爲建議和緩存結果總是零。請告知解決方案。Parse.com緩存化合物查詢
PFQuery *lotsOfWins = [PFQuery queryWithClassName:@"Class1"];
[lotsOfWins whereKey:@"Score" equalTo:@"0:]; //AND
[lotsOfWins whereKey:@"Status" notEqualTo:@"4"];
PFQuery *fewWins = [PFQuery queryWithClassName:@"Class2"];
[fewWins whereKey:@"NAME" equalTo:@"KHAN"]; AND
[fewWins whereKey:@"meetingStatus" notEqualTo:@"4"];
PFQuery *query = [PFQuery orQueryWithSubqueries:[NSArray arrayWithObjects:fewWins,lotsOfWins,nil]];
[query orderByDescending:@"updatedAt"];
query.limit = [NSNumber numberWithInt:10];
query.cachePolicy = kPFCachePolicyCacheThenNetwork; // CACHE POLICY
[query findObjectsInBackgroundWithBlock:^(NSArray *results, NSError *error) {
NSLog(@"Successfully retrieved %d results.", results.count);
if(error) {
NSLog(@"It's an error!");
}
}];
這是不正確的。限制是一個整數,而不是一個NSNumber。 query.limit = 10應該工作得很好。 –
