I'm having a problem with passing data in an multidimensional array.
So this is the Array:
var dataHome:[[String]] = []
And I would like to pass data into it like this:
if let countries_list = json as? NSArray
{
for (var i = 0; i < countries_list.count ; i++ )
{
if let country_obj = countries_list[i] as? NSDictionary
{
println(country_obj)
let countryName = country_obj["country"] as! String
let countryCode = country_obj["code"] as! String
var tempArray:[String] = []
tempArray.append(countryName)
tempArray.append(countryCode)
println(tempArray)
dataHome.append(tempArray)
println(dataHome)
}
}
}
It crashes when I try to pass data into dataHome.append(tempArray)
The array from country_obj is {code = US;country = Amerika;}
Does anybody have an solution ?
Thank's !
EDIT:
the whole function is:
func extract_json(data:NSString){
var parseError: NSError?
let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &parseError)
if (parseError == nil)
{
if let countries_list = json as? NSArray
{
for (var i = 0; i < countries_list.count ; i++ )
{
if let country_obj = countries_list[i] as? NSDictionary
{
println(country_obj)
var countryName = country_obj["country"] as! String
var countryCode = country_obj["code"] as! String
println(countryName)
println(countryCode)
var tempArray:[String] = []
tempArray.append(countryName)
tempArray.append(countryCode)
println(tempArray)
dataHome.append(tempArray)
println(dataHome)
}
}
}
}
do_table_refresh();
}
The error is: Thread 3: Breakpoint 2.1
tempArray.append(countryName)

Here is my image how my Json looks
In the api am getting global array but in this I am unable to get the children names as separate array only the last loaded array name has been getting in the array how to get the all children names in the array please help me how to get all the names in it and here is my code already tried

NOTE: Please check your data type while parsing
I too had the same problem. Instead of using for loop try using flatMap() and then extract the value using value(forKey: " ") function
let productNames = productValues.flatMap() {$0.value}
let names = (productNames as AnyObject).value(forKey: "name")
It had worked for me for my json. My Json was similar to yours.
I got separate values in array.
Trouble with JSON parsing in swift 1.2
I have an issue with the JSON parsing, i am not getting the correct data response for my parameters. i have been stuck on the issue for quite some time now. i don’t know how to fix it. i am new to iOS development. also i haven’t used any third party library.[Don’t know how to use them]
I am getting the right response for my very first iteration but for the next iteration results of previous iteration is added along with the new results. Like that each loop result is ended up with the results of previous iteration

My Output
Please some one help me fix this, Any suggestion will also do.
THANKS
Special thanks to #SMi, With his GuidLines i was able to solve my issue.
I knew that i had to clear the inner array at the end of the loop[But,didn't knew how to clear that.]
var add_it = AssetModel(rackName: AssetGroupName, rackDescription: AssetGroupDescription, totalNoAssets: totalAssets, EntityId: entityId, rackItems: assetContents)
assetData.append(add_it)
assetContents.removeAll()
All i had to do is use the .removeAll() method to clear the assetContents Array.
I have the following code that populates a UITableView. The end var holds the number of items in the JSON response. I concatenate variable n with the counter i. My problem is that in this case the JSON response carries only two items, Request1 and Request2. When the counter reaches 3 the app crashes because there is no Request3. How can I change my loop to stop when the condition counter > end is met?
let jsonData = try NSJSONSerialization.JSONObjectWithData(urlData!, options: .MutableContainers) as? NSDictionary
var end = jsonData!["num"]!
var i = 0
var n = "Request"
for item in jsonData! {
i++
n = "Request"+String(i)
var result = jsonData![n] as? NSDictionary
if let Name = result!["Name"] as? String
{
Names.append(Name)
print(Name)
}
if let Date = result!["Request_Id"] as? String
{
Dates.append(Date)
print(Date)
}
}
Try the following:
let jsonData = try NSJSONSerialization.JSONObjectWithData(urlData!, options: .MutableContainers) as? NSDictionary
var end = jsonData!["num"]!
var i = 0
var n = "Request"
for item in jsonData! {
i++
// This should do it
if i == end {
break;
}
n = "Request"+String(i)
var result = jsonData![n] as? NSDictionary
if let Name = result!["Name"] as? String
{
Names.append(Name)
print(Name)
}
if let Date = result!["Request_Id"] as? String
{
Dates.append(Date)
print(Date)
}
}
I'm assuming that by counter > end you mean i > end, as it's what seems to make sense to me.
Try starting your counter i with 1 rather than 0 incrementing it at the end of the loop like this:
let jsonData = try NSJSONSerialization.JSONObjectWithData(urlData!, options: .MutableContainers) as? NSDictionary
var end = jsonData!["num"]!
var i = 0
var n = "Request"
for item in jsonData! {
i++;
if(i==end)break;
n = "Request"+String(i)
var result = jsonData![n] as? NSDictionary
if let Name = result!["Name"] as? String
{
Names.append(Name)
print(Name)
}
if let Date = result!["Request_Id"] as? String
{
Dates.append(Date)
print(Date)
}
}
Also you can consider the following way of doing it
let jsonData = try NSJSONSerialization.JSONObjectWithData(urlData!, options: .MutableContainers) as? NSDictionary
var end = jsonData!["num"]!
var i = 0
var n = "Request"
while(i<end) { //since we are iterating on the basis on the number and specific hardcoded keys of jsondata (and not item) we can just use a normal while loop
i++;
n = "Request"+String(i)
var result = jsonData![n] as? NSDictionary
if let Name = result!["Name"] as? String
{
Names.append(Name)
print(Name)
}
if let Date = result!["Request_Id"] as? String
{
Dates.append(Date)
print(Date)
}
}
JSON function:
func extract_json(data:NSString){
var parseError: NSError?
let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &parseError)
if (parseError == nil){
if let coupon_list = json as? [String: AnyObject]{
if let coupons = coupon_list["data"] as? [AnyObject]{
for (var i = 0; i < coupons.count ; i++ ){
if let coupon_obj = coupons[i] as? NSDictionary{
let location: AnyObject? = coupon_obj.objectForKey("location")
//the print the value location
println(location)
//I just want to get the number keys before the value of the location
this is my Json object where you can see that
{
brand = "Mang Inasal";
category = (
2
);
desc = "Mang Inasal Salmonella Giveaway";
discount = 50;
"end_date" = 1443369600;
id = 2;
imgs = (
"http://mymegamobile.com/savvy/halo2x.png",
"http://mymegamobile.com/savvy/bar_filter.png",
"http://mymegamobile.com/savvy/bar_mega.png",

location = {
1435307555 = Baguio;
};
name = "Mang Inasal Halo Halo";
stamp = "2015-09-02 14:04:38";
"start_date" = 1438012800;
}
the result of the object structure is above.
How can I get the value of 1435307555 in my location?
You can do it this way:
let yourObject = location?.objectForKey("165952298") as! String
for (key,value) in coupon_list {
println(key)
}
This way you'll get all keys from the JSON
func extract_json(data:NSString){
var parseError: NSError?
let jsonData:NSData = data.dataUsingEncoding(NSASCIIStringEncoding)!
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &parseError) as! NSDictionary
if (parseError == nil) {
for (var i = 0; i < json.count ; i++ ) {
let location: AnyObject? = ((json)["location"] as! NSDictionary)["1435307555"]
//the print the value location
println(location)
}
}
