PDFlib Text Extraction Toolkit (TET) Manual

@try {
...some TET instructions...
}
@catch (TETException *ex) {
NSString * errorMessage =
[NSString stringWithFormat:@"TET error %d in '%@': %@",
[ex get_errnum], [ex get_apiname], [ex get_errmsg]];
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText: errorMessage];
[alert runModal];
[alert release];
}
@catch (NSException *ex) {
NSAlert *alert = [[NSAlert alloc] init];
[alert setMessageText: [ex reason]];
[alert runModal];
[alert release];
}
@finally {
[tet release];
}
In addition to the get_errmsg method you can also use the reason field of the exception
object to retrieve the error message.
