Objective-C 能够实现流式接收和逐字输出的效果。你可以使用 NSURLSession 来实现这一功能。以下是一个简单的示例，展示了如何使用 Objective-C 流式接收数据并逐字输出：

```
#import <Foundation/Foundation.h>

@interface StreamDemo : NSObject <NSURLSessionDataDelegate>
@property (nonatomic, strong) NSMutableData *receivedData;
@end

@implementation StreamDemo

- (instancetype)init {
self = [super init];
if (self) {
_receivedData = [[NSMutableData alloc] init];
}
return self;
}

- (void)startStreamingRequest {
NSString *urlString = @"https://api.openai.com/v1/chat/completions?stream=true";
NSURL *url = [NSURL URLWithString:urlString];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];

// 设置请求头信息
[request setValue:@"your-api-key" forHTTPHeaderField:@"Authorization"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

// 设置请求体信息
NSDictionary *body = @{@"model": @"text-davinci-002",
@"prompt": @"Your prompt here",
@"max_tokens": @30};
NSError *error;
NSData *bodyData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
if (error) {
NSLog(@"Error creating request body: %@", error);
return;
}
[request setHTTPBody:bodyData];

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];

NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request];
[dataTask resume];
}

#pragma mark - NSURLSessionDataDelegate

- (void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask didReceiveData:(NSData *)data {
[self.receivedData appendData:data];

// 在这里实现逐字输出的逻辑
NSString *receivedString = [[NSString alloc] initWithData:self.receivedData encoding:NSUTF8StringEncoding];
NSLog(@"Received Data: %@", receivedString);
}

- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(NSError *)error {
if (error) {
NSLog(@"Error: %@", error);
} else {
NSLog(@"Request completed successfully");
}
}

@end

int main(int argc, const char * argv[]) {
@autoreleasepool {
StreamDemo *streamDemo = [[StreamDemo alloc] init];
[streamDemo startStreamingRequest];

// 等待请求完成
[[NSRunLoop currentRunLoop] run];
}
return 0;
}
```

请注意，这个示例仅用于演示目的，你需要根据你的需求对其进行调整。在实际应用中，你可能需要将这个代码与你的 iOS 项目结合起来，实现逐字输出到前端界面。
