iOS Library not loaded

[alemio]

I have this error
dyld[1006]: Library not loaded: mylib.1.dylib

Reason: tried: 'mylib.1.dylib' (no such file), '/usr/local/lib/mylib.1.dylib' (no such file), '/usr/lib/mylib.1.dylib' (no such file), '//mylib.1.dylib' (no such file), '/usr/local/lib/mylib.1.dylib' (no such file), '/usr/lib/mylib.1.dylib' (no such file)

It worked in the past. I don't know why now I got this error.
Please help me
