Objective-C Dynamic Typing Code Challenge

NSLog, as you know, outputs the string to the console/log. To output the string Hello World, you do NSLog(@"Hello World");

You can dynamically replace part of it using format strings, which are preceded with the percent symbol. To output the string Our number is #, where # should be replaced by some number from a variable variable, you do

NSLog(@"Our number is %d", variable);

If variable has the value 5, %d would be replaced by the number 5, the end result is "Our number is 5"

(%d is used for integer, other options include %f for float, %@ for Objective-C object, %c for a single character, etc)

I am having the same problem! I am putting the code like this:

id thing = nil;

thing = [[NSNumber alloc] initWithInt:4];

NSLog = (@"thing = %@", thing);

and the error is:

Bummer! Compiler error! Make sure you are passing an 'NSString' to NSLog with the correct format, and check your syntax!

Somebody help!!!

so far i did the Dynamic Typing Code Challenge. I completed task 1 and task 2 but having trouble with task 3 where i have Use NSLog to print out the value of the variable 'thing'. The output should look like: "thing = 4".

need help please------>@

when i print out NSLog(@" thing is %d", thing) it says "not the correct input to NSLog"
