[英]iOS programming. How to get picture from the phone for a phonebook app
我需要您的幫助/參考/提示,以了解如何從1)iPhone中的我的圖庫和2)從iPhone前置攝像頭中獲取圖片。 這樣我的程序就可以將此圖片復制到iPhone上的本地文件夾中(而不僅僅是引用Gallery)。 謝謝
您可能會發現有關此適當的開發人員文檔的信息很有用。 您可以使用UIImagePickerController從上面的文檔中呈現一個模式視圖,如下面的代碼所示。
- (BOOL) startMediaBrowserFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// Displays saved pictures and movies, if both are available, from the
// Camera Roll album.
mediaUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeSavedPhotosAlbum];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
mediaUI.allowsEditing = NO;
mediaUI.delegate = delegate;
[controller presentModalViewController: mediaUI animated: YES];
return YES;
}
我確實建議您通讀上面的文檔,因為它非常有用,但不容易解釋。
希望這可以幫助!
