我需要将图像以512字节的块形式发送到服务器。如何压缩UIImage以便更快地将其发送到服务器
我刚刚接到图像:
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
[weakViewController dismissModalViewControllerAnimated:YES];
UIImage *shareImage = info[UIImagePickerControllerEditedImage];
imageData = UIImagePNGRepresentation(shareImage);
imageURL = [[info objectForKey:UIImagePickerControllerReferenceURL] absoluteString];
imageURL = [NSString stringWithFormat:@"%@/%d.png",[StorageManager sharedManager].storagePath, (int)[[NSDate date] timeIntervalSince1970]];
[imageData writeToFile:imageURL atomically:YES];
NSString *imageUri = [NSString stringWithFormat:@"%@/%d.jpg",[StorageManager sharedManager].storagePath, (int)[[NSDate date] timeIntervalSince1970]];
[imageData writeToFile:imageUri atomically:YES];
}
//获取图像
fileData = [[NSFileManager defaultManager] contentsAtPath:imageURL];
file=[[message.fileURL pathComponents] lastObject];
有没有办法来COMPRESS图像(使FILEDATA更小),以尽量减少大块到达目的地的时间?
你能用.jpeg重构我的代码吗?如果我从照片库中检索文件.jpeg,我可以大幅缩小文件大小吗?你能给我一个基于我发布的内容的例子吗?谢谢! – 2014-09-23 14:10:08
