打開相機：
[cpp]?view plaincopy
//先設定sourceType為相機，然后判斷相機是否可用（ipod）沒相機，不可用將sourceType設定為相片庫?? ????UIImagePickerControllerSourceType?sourceType?=?UIImagePickerControllerSourceTypeCamera;?? //????if?(![UIImagePickerController?isSourceTypeAvailable:?UIImagePickerControllerSourceTypeCamera])?{?? //????????sourceType?=?UIImagePickerControllerSourceTypePhotoLibrary;?? //????}?? ????//sourceType?=?UIImagePickerControllerSourceTypeCamera;?//照相機?? ????//sourceType?=?UIImagePickerControllerSourceTypePhotoLibrary;?//圖片庫?? ????//sourceType?=?UIImagePickerControllerSourceTypeSavedPhotosAlbum;?//保存的相片?? ????UIImagePickerController?*picker?=?[[UIImagePickerController?alloc]?init];//初始化?? ????picker.delegate?=?self;?? ????picker.allowsEditing?=?YES;//設置可編輯?? ????picker.sourceType?=?sourceType;?? ????[self?presentModalViewController:picker?animated:YES];//進入照相界面?? ????[picker?release];?? 打開相冊：（區分pad和iphone）
for iphone：
[cpp]?view plaincopy
UIImagePickerController?*pickerImage?=?[[UIImagePickerController?alloc]?init];?? ????if([UIImagePickerController?isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])?{?? ????????pickerImage.sourceType?=?UIImagePickerControllerSourceTypePhotoLibrary;?? ????????//pickerImage.sourceType?=?UIImagePickerControllerSourceTypeSavedPhotosAlbum;?? ????????pickerImage.mediaTypes?=?[UIImagePickerController?availableMediaTypesForSourceType:pickerImage.sourceType];?? ?????????? ????}?? ????pickerImage.delegate?=?self;?? ????pickerImage.allowsEditing?=?NO;?? ????[self?presentModalViewController:pickerImage?animated:YES];?? ????[pickerImage?release];?? for ipad:
[cpp]?view plaincopy
UIImagePickerControllerSourceType?sourceType?=?UIImagePickerControllerSourceTypePhotoLibrary;?? ????//sourceType?=?UIImagePickerControllerSourceTypeSavedPhotosAlbum;?//保存的相片?? ????UIImagePickerController?*picker?=?[[UIImagePickerController?alloc]?init];?? ????picker.delegate?=?self;?? ????picker.allowsEditing?=?NO;//是否允許編輯?? ????picker.sourceType?=?sourceType;?? ????/*? ?????如果從一個導航按鈕處呈現，使用：? ?????presentPopoverFromBarButtonItem:permittedArrowDirections:animated:；? ?????如果要從一個視圖出呈現，使用：? ?????presentPopoverFromRect:inView:permittedArrowDirections:animated:? ?????? ?????如果設備旋轉以后，位置定位錯誤需要在父視圖控制器的下面方法里面重新定位：? ?????didRotateFromInterfaceOrientation:（在這個方法體里面重新設置rect）? ?????然后再次調用：? ?????-?(void)presentPopoverFromRect:(CGRect)rect?inView:(UIView?*)view?permittedArrowDirections:(UIPopoverArrowDirection)arrowDirections?animated:(BOOL)animated?????????????? ?????*/?? ????//UIPopoverController只能在ipad設備上面使用；作用是用于顯示臨時內容，特點是總是顯示在當前視圖最前端，當單擊界面的其他地方時自動消失。?? ????UIPopoverController?*popover?=?[[UIPopoverController?alloc]initWithContentViewController:picker];?? ????self.imagePicker?=?popover;?? ????//permittedArrowDirections?設置箭頭方向?? ????[self.imagePicker?presentPopoverFromRect:CGRectMake(0,?0,?300,?300)?inView:self.view?permittedArrowDirections:UIPopoverArrowDirectionAny?animated:YES];?? ????[picker?release];?? ????[popover?release];??
點擊相冊中的圖片 貨照相機照完后點擊use??后觸發的方法
- (void)imagePickerController:(UIImagePickerController?*)picker?didFinishPickingMediaWithInfo:(NSDictionary?*)info
點擊cancel 調用的方法
- (void)imagePickerControllerDidCancel:(UIImagePickerController?*)picker?
