すべての日付の最初のレコードのみを表示したいとします。 だから、誰でも助けてくれますか？

私はあなたがこのように試すことができ、特定の日付のための唯一の最初のオブジェクトを使用する場合はラベル

Answer 1

に表示する必要が太字。

NSArray *dataPoints = [tideDic objectForKey:@"dataPoints"]; 
NSMutableArray *firstObjects = [[NSMutableArray alloc] init]; 
NSMutableArray *dayArray = [[NSMutableArray alloc] init]; 

for (NSDictionary *dic in dataPoints) { 
    NSString *locatationTime = [dic objectForKey:@"Localtime"]; 
    NSString *dateOnly = [[locatationTime componentsSeparatedByString:@" "] firstObject]; 
    if (![dayArray containsObject:dateOnly]) { 
     [dayArray addObject:dateOnly]; 
     [firstObjects addObject:dic]; 
    } 
}
