如何將對象從NSDictionary添加到UIActionSheet UIButton列表的NSArray

Question

我的字典

    myDictionary = [[publicDataCityArray valueForKey:@"data"] valueForKey:@"name"];

    NSLog(@"myDictionary is %@ myDictionary count is %i",   myDictionary,  [myDictionary count]);

NSLog輸出：

myDictionary is (
    Roma,
    Milano,
    Rimini,
    Venezia,
    Firenze,
    Napoli,
    Cesenatico,
    Cervia,
    Recco,
    "Abano Terme",
    "Abbadia Cerreto",
    "Abbadia Lariana",
    "Abbadia San Salvatore",
    Abbasanta,
    Abbateggio,
    Abbiategrasso,
    Abetone,
    Abriola,
    Acate,
    Accadia,
    Acceglio,
    Accettura,
    Acciano,
    Accumoli,
    Acerenza,
    Acerno,
    Acerra,
    "Aci Bonaccorsi",
    "Aci Castello",
    "Aci Catena",
    "Aci Sant'Antonio",
    Acireale,
    Acquacanina,
    Acquafondata,
    Acquaformosa,
    Acquafredda,
    Acqualagna,
    "Acquanegra Cremonese",
    "Acquanegra sul Chiese",
    Acquapendente
) myDictionary count is 40

我正在嘗試填充UIActionSheet數組：

-(void) someMethod{

    NSError *requestError = nil;

    NSString *savedValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"token"];

    NSString *stringWithToken = [NSString stringWithFormat:@"%@&token=%@",kCityURL, savedValue];

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:stringWithToken]];

    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&requestError];

    NSError *jsonParsingError = nil;

    if (requestError) {
        NSLog(@"sync. request failed with error: %@", requestError);
    }
    else {
        // handle data
        NSArray *publicDataCityArray =  [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];

        myDictionary = [[publicDataCityArray valueForKey:@"data"] valueForKey:@"name"];

        NSLog(@"myDictionary is %@ myDictionary count is %i",   myDictionary,  [myDictionary count]);

        for (NSDictionary *publicCityDataDict in publicCityDataArray) {

            arrayCitiesActionSheet = [[NSArray alloc] initWithObjects: myDictionary, @"city5", @"city6", @"city7", @"city8",@"city9", @"city10", @"city11", @"city12", @"city13", @"city14", @"city15", @"city16", nil];


           // arrayCitiesActionSheet = [myDictionary allValues];

        }

    }

    UIActionSheet* actionSheet = [[UIActionSheet alloc] init];

    actionSheet.title = @"SELECT A CITY";

    actionSheet.delegate = self;

    for(int i=0;i<[myDictionary count];i++)

    {

        [actionSheet addButtonWithTitle:[arrayCitiesActionSheet objectAtIndex:i]];

    }

    actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:@"Cancel"];

    [actionSheet showInView:[UIApplication sharedApplication].keyWindow];

}

您是否嘗試過將myDictionary作為數組，

嘗試這個 ，

 for(int i=0;i<[myDictionary count];i++)
    {
        [actionSheet addButtonWithTitle:[arrayCitiesActionSheet objectAtIndex:i]];
    }

替換為

for(int i=0;i<[myDictionary count];i++)
        {
            [actionSheet addButtonWithTitle:[myDictionary objectAtIndex:i]];
        }
