Question

My iphone app is accessing a JSON service which returns something like:

{"theResult":{"Total":1.5, "Comment":"some comment"}}

The code I’m using successfully parses any NSStrings such as the comment field above but I am having trouble with numeric values.

NSDictionary *res= [json objectForKey:@"theResult"];
NSString *comment = [res objectForKey:@"Comment"];
NSDecimal *total = (__bridge NSDecimal *)[res objectForKey:@"Total"]; 

The *total variable does not get set correctly and causes a EXC_BAD_ACCESS error.

How do I parse numeric values in objective-c?

Answer 1

convert the object to the correct data type, like this

float total = [[res objectForKey:@"Total"] floatValue];
