Parsing JSON response .

问题

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
   response=[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];}

Here, I get the response in the "response value" --> [{"response":true,"danger":false}]

The thing is: How can I rescue the "danger"(true/false) into a new variable to use it in other methods? I need to know if "danger" is true or false becouse if its true, i have to show an alert.

I would really appreciate someone help, as I am stuck in here.

回答1:

use NSJSONSerialization: http://developer.apple.com/library/ios/#documentation/Foundation/Reference/NSJSONSerialization_Class/Reference/Reference.html

NSArray *jsonArray=[NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
BOOL danger=[(NSNumber*)[(NSDictionary*)[jsonArray objectAtIndex:0] objectForKey:@"danger"] boolValue];
