我正在尝试通过套接字将图像发送到服务器,但图像在服务器端不能很好地显示。
我正在使用此代码,可能是什么问题?我正在向服务器发送文本并且它可以工作,但图像看起来没有格式化。
UIImage *imageResized=[self resizeImage:editedImage newSize:CGSizeMake(64,32)];
NSData *imageData = UIImageJPEGRepresentation(imageResized, 1.0f);
NSString *encodedString = [imageData base64EncodedStringWithOptions:nil];
NSString *finalStr= [NSString stringWithFormat:@"image:%@",encodedString];
NSData* data = [finalStr dataUsingEncoding:NSASCIIStringEncoding];
[tcpsocket initNetworkCommunication:[tcpSocket linkWebserviceInet1] porta:[tcpSocket linkWebport]];
[tcpsocket sendNSData:data];
- (UIImage *)resizeImage:(UIImage*)image newSize:(CGSize)newSize {
CGRect newRect = CGRectIntegral(CGRectMake(0, 0, newSize.width, newSize.height));
CGImageRef imageRef = image.CGImage;
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0);
CGContextRef context = UIGraphicsGetCurrentContext();
// Set the quality level to use when rescaling
CGContextSetInterpolationQuality(context, kCGInterpolationHigh);
CGAffineTransform flipVertical = CGAffineTransformMake(1, 0, 0, -1, 0, newSize.height);
CGContextConcatCTM(context, flipVertical);
// Draw into the context; this scales the image
CGContextDrawImage(context, newRect, imageRef);
// Get the resized image from the context and a UIImage
CGImageRef newImageRef = CGBitmapContextCreateImage(context);
UIImage *newImage = [UIImage imageWithCGImage:newImageRef];
CGImageRelease(newImageRef);
UIGraphicsEndImageContext();
return newImage;
