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: 
You should not use backticks with column values. you have to use either single or double quotes otherwise mysql will consider that value as a column name.

```
SELECT * 
FROM  `users`
WHERE  `IP` = '123.231.213.132'

```
It might be the single speach mark symbol. Try replacing them manually.
