Behöver lite hjälp med några buggar... Cocao..

första buggen :

NSArray *fileTypes = [NSArray arrayWithObjects:@pdf, @tiff, @jpg, nil];

felet: parse error before `*'

andra buggen:
result = [_openPanel runModalForDirectory:NSHomeDirectory() file:nil types:fileTypes];

2 fel: `result' undeclared (first use in this function)
(Each undeclared identifier is reported only once
for each function it appears in.)
