今天写道需要选取照片(可以拍照或者选取图库的),不废话,上代码
这个是点击事件
<code>
//提交选项
-(void)sendDataAction:(UIButton *) button{

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照", @"从相册选择", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
[actionSheet showInView:self.view];

}
//这里做个判断

• (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
  {
  if (buttonIndex == 0) {
  [self toCameraPickingController];
  }
  else if (buttonIndex == 1) {
  [self toPhotoPickingController];
  }

}
//相机判断

• (void)toCameraPickingController
  {
  if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
  NSLog(@"Error:没有照相设备");
  }
  else {
  UIImagePickerController *cameraPicker = [[UIImagePickerController alloc] init];
  cameraPicker.delegate = self;
  cameraPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
  if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]) {
  [self presentViewController:cameraPicker animated:YES completion:nil];
  }
  else {
  // [self presentModalViewController:cameraPicker animated:YES];这个是找的demo里面的,这个方法过时了,被下面的替代了
  [self presentViewController:cameraPicker animated:YES completion:nil];

    }
    [_sendDataButt setTitle:@"已上传" forState:UIControlStateNormal];
  

  }
  }
  //图库判断

• (void)toPhotoPickingController
  {
  if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
  NSLog(@"Error:无图片库");
  }
  else {
  UIImagePickerController *photoPicker = [[UIImagePickerController alloc] init];
  photoPicker.delegate = self;
  photoPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
  if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]) {
  [self presentViewController:photoPicker animated:YES completion:nil];
  }
  else {
  // [self presentModalViewController:photoPicker animated:YES];这个是找的demo里面的,这个方法过时了,被下面的替代了
  [self presentViewController:photoPicker animated:YES completion:nil];
  }
  [_sendDataButt setTitle:@"已上传" forState:UIControlStateNormal];

  }
  }

pragma mark UIImagePickerControllerDelegate Methods

//图片选择

• (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
  {
  if ([self respondsToSelector:@selector(dismissViewControllerAnimated:completion:)]) {
  [picker dismissViewControllerAnimated:YES completion:nil];
  }
  else {
  //[picker dismissModalViewControllerAnimated:YES];这个是找的demo里面的,这个方法过时了,被下面的替代了
  [self dismissViewControllerAnimated:YES completion:nil];
  }
  UIImage *imagePicked = [info objectForKey:UIImagePickerControllerOriginalImage];
  _sendImage.image = imagePicked;
  }

pragma mark UIImagePickerControllerDelegate Cancel Methods

• (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
  {
  //[picker dismissModalViewControllerAnimated:YES];这个是找的demo里面的,这个方法过时了,被下面的替代了
  [self dismissViewControllerAnimated:YES completion:nil];
  }
  //设置一下屏幕
• (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
  {
  return (interfaceOrientation == UIInterfaceOrientationPortrait);
  }

</code>

补充一下,携带参数上传

• (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
  {
  NSLog(@"图片选中");
  //截取图片
  UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
  NSData *imageData = UIImageJPEGRepresentation(image, 0.001);
  self.mv.portraitImageView.image = image;

  AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
  manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"text/plain", nil nil];
  // 参数
  NSMutableDictionary *parameter = [NSMutableDictionary dictionary];
  parameter[@"token"] = "param....";
  // 访问路径
  NSString *stringURL = [NSString stringWithFormat:@"%@%@",HOSTURL,kUploadAvatar];

  [manager POST:stringURL parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
  // 上传文件
  NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
  formatter.dateFormat = @"yyyyMMddHHmmss";
  NSString *str = [formatter stringFromDate:[NSDate date]];
  NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];

    [formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/png"];  
  

  } success:^(AFHTTPRequestOperation *operation, id responseObject) {
  NSLog(@"上传成功");
  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
  NSLog(@"上传错误");
  }];
  }
