¬	Click the next button. 

If you know that a particular method has an error in it somewhere, you can execute that method a line at a time (called stepping) to see exactly where the error occurs. 

¬

The next button always executes until control returns to the line of code directly below the current line. That is, if the current line contains a function call or invokes an Objective-C method, the entire function or method is executed, and the program doesn't stop until it returns (unless a breakpoint is hit).
