Following your suggestion, I changed my predicateFormat to:
@"%@ contains kMDItemTextContent" which translates into:
<kMDItemTextContent IN "To be, or not to be"> and behaves more or
less
exactly like LIKE.
So again: how to search kMDItemTextContent for a string containing
spaces?
(10.4.11).
This came up in the last question you asked. You're not constructing
your formats properly.
[NSPredicate predicateWithFormat:@"%K contains %@",
kMDItemTextContent, @"To be, or not to be"]
Constucting the format properly (copying your suggestion):
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"%K
contains %@", kMDItemTextContent, @"To be, or not to be"];
results in:
[...] Exception raised during posting of notification. Ignored.
exception: NSComparisonPredicate with left expression which is not
NSKeyPathExpressionType given to NSMetadataQuery ("To be, or not to
be" IN kMDItemTextContent)
So: what am I doing wrong?
Kind regards
Gerriet.
