我在api的nsmutabledictionay中提供数据，我需要将这些数据添加到tableview单元格中，所以我需要将其转换为nsmutable数组。但是当试图将数据从dictonary添加到aarray时，它只选择了dictonary的最后一个对象。请看看我的代码和回复。
i need to parse stop1 and stop2 address
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:theRequest
completionHandler:
^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(@"Response:%@ %@\n", response, error);
if(error == nil)
{
NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog(@"Data = %@",text);
}
dictionary = [[NSJSONSerialization JSONObjectWithData:data options:0 error:nil]objectForKey:@"data"];
NSMutableDictionary *temp = [NSMutableDictionary new];
NSArray *IDArray = [dictionary objectForKey:@"docs"];
for (NSDictionary *Dict in IDArray)
{
[temp setObject:[Dict objectForKey:@"_id"] forKey:@"_id"];
NSLog(@"id %@", temp);
}
[getid addObject:temp];
NSLog(@"getid details %@", getid);
if (getid)
{
[_ScheduleRidetable reloadData];
}
}];

getid = [NSMutableArray New];
for (NSDictionary *Dict in IDArray)
{
NSMutableDictionary *temp = [NSMutableDictionary new];
[temp setObject:[Dict objectForKey:@"_id"] forKey:@"_id"];
// for fetch stop1 and stop2 use like
NSMutableDictionary *stp1 = [Dict objectForKey:@"stop1"]
if ([[stp1 allKeys] containsObject:@"address"]) {
// key exists.
[temp setObject:[stp1 objectForKey:@"address"] forKey:@"address"];
}
}
NSMutableDictionary *stp2 = [Dict objectForKey:@"stop2"] ;
if ([[stp2 allKeys] containsObject:@"address"]) {
// key exists.
[temp setObject:[stp2 objectForKey:@"address"] forKey:@"address1"];
}
[getid addObject:temp];
}
if (getid.count>0)
{
[_ScheduleRidetable reloadData];
}
<强>步骤-2
在tableview中检索
idname.text = [getid objectAtIndex:objectAtIndex:indexPath.row]objectForKey:@"_id"];
stop2.text = [getid objectAtIndex:objectAtIndex:indexPath.row]objectForKey:@"address1"];
stop1.text = [getid objectAtIndex:objectAtIndex:indexPath.row]objectForKey:@"address"];
答案 1 :(得分：1)
您正在为for循环[temp setObject:[Dict objectForKey:@"_id"] forKey:@"_id"];设置相同键的值每次覆盖_id的值时，所以当您将其添加到getid数组时，它只有{{1}用它的价值。
现在，如果你想要字典数组，那么你可以简单地将你的_id语句放入for循环中（最后）
如果你想要它的数组值（字符串数组），这里的字符串意味着你的id就像[getid addObject:temp];那么你可以做类似的事情，
在573c0acf261b2bc76e228717，
for loop所以这只会在getid数组中添加id。你的数组看起来像： [getid addObject:[Dict objectForKey:@"_id"] forKey:@"_id"];
希望这会有所帮助：）

Array *IDArray = [dictionary objectForKey:@"docs"];
for (NSDictionary *Dict in IDArray)
{
NSMutableDictionary *temp = [NSMutableDictionary new];
[temp setObject:[Dict objectForKey:@"_id"] forKey:@"_id"];
[getid addObject:temp];
}
答案 3 :(得分：0)
因为NSMUtableDictionary只有一个键，你可以
for（int i=0,i< IDArray.count,i++）{
[temp setObject:[Dict objectForKey:@"_id"] forKey:[NSString stringformationWith @"_id%d",i]];
}
答案 4 :(得分：0)
Use this code,
NSMutableArray *tempArray=[[NSMutableArray alloc]init];
for (NSDictionary *Dict in IDArray)
{
[tempArray setValue:[Dict objectForKey:@"_id"] forKey:@"id"];
};
[allValues addObjectsFromArray:tempArray];
allValues也是NSMutableArray，
希望它有用
