從iphone應用程序啓動照片庫應用程序

Question

是否可以從我的應用程序啓動（將用戶重定向到）本機照片庫應用程序，類似於電子郵件？這是現在可能在4.2 SDK？

Answer 1

對於這一點，你必須創建和呈現UIImagePickerController這樣的：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
imagePicker.delegate = self; 
imagePicker.allowsEditing = YES; 
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
[self presentModalViewController:imagePicker animated:YES]; 

您可以更改imagePicker.sourceType到imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;如果你希望用戶使用相機來代替。

委託方法：- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info會給你在info字典中的圖像。
