The class names, method names, and parameter names must all be spelled correctly, including proper case. You must either use code completion to make sure they are valid, or carefully read the class reference documentation on the specific class/method/parameters. This information is usually one click away in Xcode Quick Help inspector. For example, the UIAlertView class reference clearly describes the parameters.
