从iphone应用程序启动照片库应用程序

Question

是否可以从我的应用程序启动（将用户重定向到）本机照片库应用程序，类似于电子邮件？这是现在可能在4.2 SDK？

Answer 1

对于这一点，你必须创建和呈现UIImagePickerController这样的：

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;如果你希望用户使用相机来代替。

委托方法：- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info会给你在info字典中的图像。
