Xcode-->product-->Anslyze

NSString *fileName = [[NSString alloc] init]; //Value stored to 'fileName' during its initialization is never read

if ([info objectForKey:UIImagePickerControllerReferenceURL])
{
fileName = [[info objectForKey:UIImagePickerControllerReferenceURL] absoluteString];
fileName = [self getFileName:fileName];
}
else
{
fileName = [self timeStampAsString];
}

[[NSUserDefaults standardUserDefaults] setValue:fileName forKey:@"fileName"];

修改为

NSString *fileName;

if ([info objectForKey:UIImagePickerControllerReferenceURL])
{
fileName = [[info objectForKey:UIImagePickerControllerReferenceURL] absoluteString];
fileName = [self getFileName:fileName];
}
else
{
fileName = [self timeStampAsString];
}

[[NSUserDefaults standardUserDefaults] setValue:fileName forKey:@"fileName"];
