// 从照片库里面选取
- (void)pickerFromPhotoLib
{
   UIImagePickerController *imagepicker = [[UIImagePickerController alloc] init];
   imagepicker.delegate = self;
   imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
   imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
   imagepicker.allowsEditing = YES;
   [self presentModalViewController:imagepicker animated:YES];
}
// 从相机获取
-(void)pickerFromCameraSource
{
   UIImagePickerController * imagepicker = [[UIImagePickerController alloc] init];
   imagepicker.delegate = self;
   imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
   imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
   imagepicker.allowsEditing = YES;
   [self presentModalViewController:imagepicker animated:YES];
}

//完成选取
- (void)imagePickerController:(UIImagePickerController *)picker
                               didFinishPickingImage:(UIImage *)image
                               editingInfo:(NSDictionary *)editingInfo
{
    //image为选中图片
   [[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
// 取消选取
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
   [picker dismissModalViewControllerAnimated:YES];

}

记得在ViewController加上托管 UIImagePickerControllerDelegate
