Question

如何在iPhone上通过套接字发送图像。我尝试使用字符串我使用的代码如下，现在我需要通过套接字发送图像。

CFWriteStreamRef writeStream = NULL;

CFStringRef host = CFSTR("192.168.1.211");
UInt32 port = 8001;

CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, host, port, NULL, &writeStream);

CFWriteStreamSetProperty(writeStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue);

if(!CFWriteStreamOpen(writeStream)) {
    NSLog(@"Error Opening Socket");
}
else{


    UInt8 buf[] = "Abc";        


    int bytesWritten = CFWriteStreamWrite(writeStream, buf, strlen((char*)buf));

    NSLog(@"Written: %d", bytesWritten);

    if (bytesWritten < 0) {
        CFStreamError error = CFWriteStreamGetError(writeStream);

    }

}

此致

图片必须转换为 base64 字符串并通过 socket 传输。

以下是Objective c

中base-64转换的代码段

- (NSString *)encodeToBase64String:(UIImage *)image {
 return [UIImagePNGRepresentation(image) base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
}

夫特

let strBase64:String = imageData.base64EncodedStringWithOptions(.Encoding64CharacterLineLength)

以下是reference
