How to locate where the bug is for "unrecognized selector sent to instance"?

Sometimes my app crashes because of this error log:

-[NSNull floatValue]: unrecognized selector sent to instance 0x3befd090

I didn't call any "floatValue", so how can I locate which exact line crash the app?

To reproduce the crash require some specific data from the website I have no control over, so any ideas to fix this? Thanks.

The easiest way is to add an Exception Breakpoint.

Go to the back point pane and click op de + in the left corner. In popup select Add Exception Breakpoint.

Just click Done in the popup, no you have a breakpoint on any exception thrown by the debugger which will allow you to locate the line where the error is thrown.
