Question: In **`presentPopoverFromRect:inView:permittedArrowDirections:animated:`**, method of **`UIPopoverViewController`**, for "**`presentPopoverFromRect`**", what I have understood is that "**`x`**" and "**`y`**" are where it will point its anchor but what "**`width`**" and "**`height`**" parameter will do?

I am playing with them by setting different values and result is very confusing.

Answer: 
What's with the backticks? Use single quotes
Also I'm assuming that users is a table name and IP is an entity of users.

Also...you have to end your statement with a semi-colon
It might be the single speach mark symbol. Try replacing them manually.
