To set a breakpoint Objective C selectors named alignLeftEdges: you can enter either of:
(lldb) breakpoint set --selector alignLeftEdges:
(lldb) breakpoint set -S alignLeftEdges:
You can limit any breakpoints to a specific executable image by using the "--shlib <path>" ("-s <path>" for short):
(lldb) breakpoint set --shlib foo.dylib --name foo
(lldb) breakpoint set -s foo.dylib -n foo
Suggestions on more interesting primitives of this sort are also very welcome.
Just like gdb, the lldb command interpreter does a shortest unique string match on command names, so the following two commands will both execute the same command:
(lldb) breakpoint set -n "-[SKTGraphicView alignLeftEdges:]"
(lldb) br s -n "-[SKTGraphicView alignLeftEdges:]"
