I have JSON like this:
[{
"username":"bitu","password":"123456", "id":"1"
},
{
"username":"admin","password":"admin", "id":"2"
},
{
"username":"demo","password":"demo", "id":"3"
},
{
"username":"admin","password":"admin", "id":"8"
},
{
"username":"admin","password":"admin", "id":"5"
}]
I want to use NSMutableArray for get "id". How I can do it?
Help me, please!
NSLog(@"%@",[[yourArray objectAtIndex:index] valueForKey:@"id"]);
Get Value with objectAtIndex and valueForKey from NSMutableArray
NSString *UserName = [[yourArray objectAtIndex:index] valueForKey:@"username"];//if you required
NSString *Password = [[yourArray objectAtIndex:index] valueForKey:@"password"];//if you required
NSString *UID = [[yourArray objectAtIndex:index] valueForKey:@"id"];
:)
let NSArray *info array contains your data. Here I am going to retrive your data and save it in NSMutableArray name, password and id.
Initailise these arrays at viewDidLoad methods as
NSMutableArray name=[[NSMutableArray alloc] init];
NSMutableArray password=[[NSMutableArray alloc] init];
NSMutableArray id=[[NSMutableArray alloc] init];
Use following code after retriving JSON response
NSArray *info; // this array contains your data
int counter=[info count];
for(int i=0;i<counter;i++)
{
NSDictionary *currentObject=[info objectAtIndex:i];
NSString *userName=[currentObject objectForKey:@"username"];
NSString *userPassword=[currentObject objectForKey:@"password"];
NSString *userID=[currentObject objectForKey:@"id"];
[name addObject:userName];
[password addObject:userPassword];
[id addObject: userID];
}
NSMutableArray *idArray = [[NSMutableArray alloc] init];
for (NSDictionary *obj in yourJsonArray) {
[idArray addObject:[obj objectForKey:@"id"]];
}
NSLog(@"%@",idArray);
Example, Array have string objects.
Acccess:
NSString.FromHandle(deviceList.ValueAt(i));
