AF의 사용

1. AFSecurityPolicy 사용

- (AFSecurityPolicy *)securityPolicy{
    [NSMutableArray arrayWithCapacity:1];
    // .crt --->.cer
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"https" ofType:@"cer"];
    NSData   *data    = [NSData dataWithContentsOfFile:cerPath];
    NSLog(@"%@",[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);// 
    NSSet    *cerSet  = [NSSet setWithObject:data];
    AFSecurityPolicy *security = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate withPinnedCertificates:cerSet];
    [AFSecurityPolicy defaultPolicy];
    
    security.allowInvalidCertificates = YES;
    security.validatesDomainName      = NO;
    return security;
}

2. 처음 앱을 다운로드하여 설치할 때 네트워크가 없는 버그를 해결한다.
