我有一個生成位置的軌道API,以及這些位置的菜單。在我的iOS應用程序中,我使用AFNetworking在表格視圖中檢索這些位置的json列表。AFNetworking嵌套參數請求
這是AFNetworking要求我用得到的位置數據
LocationTableViewController.m
[[LocationApiClient sharedInstance] getPath:@"locations.json" parameters:nil
success:^(AFHTTPRequestOperation *operation, id response) {
NSLog(@"Response: %@", response);
NSMutableArray *results = [NSMutableArray array];
for (id locationDictionary in response) {
Location *location = [[Location alloc] initWithDictionary:locationDictionary];
[results addObject:location];
}
self.results = results;
[self.tableView reloadData];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error fetching locations!");
NSLog(@"%@", error);
}];
的JSON的樣品返回的位置請求
{
"created_at" = "2013-02-23T19:25:26Z";
id = 2;
lat = "48.870175";
long = "2.779899999999998";
name = "Disneyland Hotel";
"places_id" = fd90769e2cf40d6cb6cb1a3d0bfd0ce5d37ed331;
"street_address" = "Rue de la Marni\U00e8re, Chessy, France";
"updated_at" = "2013-02-23T19:25:26Z";
},
名稱和地址顯示
當用戶點擊位置單元格時,我想顯示該位置啤酒列表的表格視圖。導軌API路線(用於LOCATION_ID => 1)是http://localhost:3000/locations/1/beers.json
和輸出以下JSON爲屬於LOCATION_ID啤酒:1
{
"created_at":"2013-02-23T19:25:53Z",
"description":"fkjgvjkg",
"id":1,"location_id":1,
"name":"nhoihioh",
"price":"2.5","style":"ipa",
"updated_at":"2013-02-23T19:25:53Z"
}
當用戶點擊的位置處小區我想顯示的是,啤酒列表位置,通過http://localhost:3000/locations/(whatever location_id is associated with the table cell that was tapped)/beers.json
消耗如何將location_id插入到下一個表視圖中發生的AFNetworking請求中,當用戶點擊位置單元格時?
BeerTableViewController.m
[[LocationApiClient sharedInstance] getPath:@"locations/**(location_id from location table cell inserted here)**/beers.json" parameters:nil
success:^(AFHTTPRequestOperation *operation, id response) {
NSLog(@"Response: %@", response);
NSMutableArray *results = [NSMutableArray array];
for (id beerDictionary in response) {
Beer *beer = [[Beer alloc] initWithDictionary:beerDictionary];
[results addObject:beer];
}
self.results = results;
[self.tableView reloadData];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error fetching beers!");
NSLog(@"%@", error);
}];
我想我需要登錄的LOCATION_ID並傳遞價值,當表格單元格被點擊的URL設置了一個param,但我不知道該怎麼做。
