AFNetworking https自签名证书

我在服务器上有自签名证书验证.当我尝试在mac上的浏览器中使用api https://wikiroutes.info/test/api/ios/getCities时,它的工作仅在我接受.p12证书时.我找不到在AFNetworking中输入.p12密码的位置.我也有文件.der,但是当我使用它时,我kSecTrustResultRecoverableTrustFailure的代码有错误SecTrustEvaluate(allowedTrust, &result)

我的代码

NSString* fileRoot = [[NSBundle mainBundle] pathForResource:@"cert.pem" ofType:@"der"];
NSData *certData = [[NSData alloc] initWithContentsOfFile:fileRoot];

AFSecurityPolicy *securityPolicy = [[AFSecurityPolicy alloc] init];
securityPolicy.SSLPinningMode = AFSSLPinningModeCertificate;
[securityPolicy setAllowInvalidCertificates:YES];
securityPolicy.pinnedCertificates = @[certData];

AFHTTPRequestOperationManager *operationManager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"https://wikiroutes.info"]];
operationManager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
operationManager.securityPolicy = securityPolicy;

[operationManager GET:@"test/api/ios/getCities" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"response %@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error %@",error);
}];

这是我的测试项目.https://www.dropbox.com/s/410w5bau3e3slx9/testApp.zip
