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

new Objective-c supports this new syntax for static initialisation.

@{key:value}

For example:

NSDictionary* dict = @{@"x":@(acceleration.x), @"y":@(acceleration.y), @"z":@(acceleration.z), @"date":[NSDate date]};
