how i use this files

Found this from WLSimpleMapAnnotation page in LaFrance's blog.
Thanks guys!

On line 63 there is an assignment in the if..
Xcode told me that perhaps it should be:
if (self == [super init]) {

:)

Best Regards

@EO2 it should be like if ((self = [super init])) since we're checking if the assigned worked not if it actually equal.

Thanks for the quick update :)

Thanks, very useful shortcut through some tedious programming. Found from WLSimpleMapAnnotation. Note that I believe you can remove _dealloc and autorelease calls for new ARC compiler.
