Creating an NSDictionary

Question

In the following code, the first log statement shows a decimal as expected, but the second logs NULL. What am I doing wrong?

NSDictionary *entry = [[NSDictio         


        

Answer 1

You are exchanging the order in which you insert objects and key: you need to insert first the object, then the key as shown in the following example.

NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:@"value1", @"key1", @"value2", @"key2", nil];
