如何将图片、文件发送到指定服务器

回答：

融云SDK默认将图片文件消息上传默认的文件服务器，如果需要将您自己的服务器，那么可以采用下面的方案

1，调用RCIMClient的接口

- (RCMessage *)sendMediaMessage:(RCConversationType)conversationType

targetId:(NSString *)targetId

content:(RCMessageContent *)content

pushContent:(NSString *)pushContent

pushData:(NSString *)pushData

uploadPrepare:(void (^)(RCUploadMediaStatusListener *uploadListener))uploadPrepareBlock

progress:(void (^)(int progress, long messageId))progressBlock

success:(void (^)(long messageId))successBlock

error:(void (^)(RCErrorCode errorCode, long messageId))errorBlock

cancel:(void (^)(long))cancelBlock

在uploadPrepareBlock中写代码上传您的图片、文件到您的服务器，uploadListener具体的实现可以参考下面代码，具体实现是根据上传的进度与过程给uploadListener的相关block赋值；可以在progressBlock中根据progress的值来更新UI

2、调用RCConversationViewController的接口

- (void)sendMediaMessage:(RCMessageContent *)messageContent

pushContent:(NSString *)pushContent

appUpload:(BOOL)appUpload;

同时需要实现下面的接口

- (void)uploadMedia:(RCMessage *)message

uploadListener:(RCUploadMediaStatusListener *)uploadListener;

在该方法中给上传到您服务器的代码，并更新uploadListener中相关block的状态

可以参考下面代码：

RCImageMessage *imgMsg = [RCImageMessage messageWithImage:image];

[self sendMediaMessage:imgMsg pushContent:nil appUpload:YES];

- (void)uploadMedia:(RCMessage *)message

uploadListener:(RCUploadMediaStatusListener *)uploadListener {

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

//这里是模仿图片、文件上传的过程

BOOL isSuccess = NO;

int i = 0;

for (i = 0; i < 100; i++) {

uploadListener.updateBlock(i);

[NSThread sleepForTimeInterval:0.2];

isSuccess = YES;

}

if(isSuccess){//如果上传成功

uploadListener.successBlock(@"http://www.rongcloud.cn/images/newVersion/bannerInner.png?0717");

}else {//如果上传失败

uploadListener.errorBlock(-1);

}

});

}

我对此仍有疑问！继续追问
