//先设定sourceType为相机，然后判断相机是否可用（ipod）没相机，不可用将sourceType设定为相片库 UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera; // if (![UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) { // sourceType = UIImagePickerControllerSourceTypePhotoLibrary; // } //sourceType = UIImagePickerControllerSourceTypeCamera; //照相机 //sourceType = UIImagePickerControllerSourceTypePhotoLibrary; //图片库 //sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; //保存的相片 UIImagePickerController *picker = [[UIImagePickerController alloc] init];//初始化 picker.delegate = self; picker.allowsEditing = YES;//设置可编辑 picker.sourceType = sourceType; [self
