Answer 1

In Xcode 4 you can set an exception breakpoint in the breakpoint editor. Every time an exception is thrown (or caught depending on how you set it up), your application will pause on the line that threw the exception.

add an exception breakpoint by clicking the breakpoints tab at the top of the left pane, then click the plus sign at the lower left. Add an exception breakpoint.
