Objective-C Language NSJSONSerialization JSON Parsing using NSJSONSerialization Objective c
Example
NSError *e = nil;
NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"sam\"}]";
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e];
if (!jsonArray) {
NSLog(@"Error parsing JSON: %@", e);
} else {
for(NSDictionary *item in jsonArray) {
NSLog(@"Item: %@", item);
}
}
Output:
Item: {
id = 1;
name = sam;
}
Example 2:Using contents of url:
//Parsing:
NSData *data = [NSData dataWithContentsOfURL:@“URL HERE”];
NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(@“json :%@”,json);
Sample response:
json: {
MESSAGE = “Test Message";
RESPONSE =(
{
email = "[email protected]";
id = 15;
phone = 1234567890;
name = Staffy;
}
);
STATUS = SUCCESS;
}
NSMutableDictionary *response = [[[json valueForKey:@"RESPONSE"] objectAtIndex:0]mutableCopy];
NSString *nameStr = [response valueForKey:@"name"];
NSString *emailIdStr = [response valueForKey:@"email"];
