2. Set the sourcetype as the camera, then determine if the camera is available (ipod), no camera, no sourcetype set as photo gallery
4. Uiimagepickercontrollersourcetype sourcetype = Uiimagepickercontrollersourcetypecamera;
6. if (![ Uiimagepickercontroller Issourcetypeavailable:uiimagepickercontrollersourcetypecamera]) {
8. SourceType = uiimagepickercontrollersourcetypephotolibrary;
10. //    }
12. SourceType = Uiimagepickercontrollersourcetypecamera; Camera
14. SourceType = uiimagepickercontrollersourcetypephotolibrary; Photo Gallery
16. SourceType = Uiimagepickercontrollersourcetypesavedphotosalbum; Saved photos
18. Uiimagepickercontroller *picker = [[Uiimagepickercontroller alloc] init]; //Initialize
20. Picker.delegate = self;
22. picker.allowsediting = YES; //settings can be edited
24. Picker.sourcetype = sourcetype;
26. [Self presentmodalviewcontroller:picker animated:yes]; //Enter the camera interface
28. [Picker release];

Open Album: (differentiate between pad and iphone)

For iphone:

[CPP]View Plaincopy

2. Uiimagepickercontroller *pickerimage = [[Uiimagepickercontroller alloc] init];
4. if ([Uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypephotolibrary]) {
6. Pickerimage.sourcetype = uiimagepickercontrollersourcetypephotolibrary;
8. //pickerimage.sourcetype = uiimagepickercontrollersourcetypesavedphotosalbum;
10. Pickerimage.mediatypes = [Uiimagepickercontroller availableMediaTypesForSourceType:pickerImage.sourceType];
14. }
16. Pickerimage.delegate = self;
18. pickerimage.allowsediting = NO;
20. [Self presentmodalviewcontroller:pickerimage animated:yes];
22. [Pickerimage release];

For ipad:

[CPP]View Plaincopy

2. Uiimagepickercontrollersourcetype sourcetype = uiimagepickercontrollersourcetypephotolibrary;
4. //sourcetype = uiimagepickercontrollersourcetypesavedphotosalbum;//Saved photos
6. Uiimagepickercontroller *picker = [[Uiimagepickercontroller alloc] init];
8. Picker.delegate = self;
10. picker.allowsediting = NO; //whether to allow editing
12. Picker.sourcetype = sourcetype;

18. PresentPopoverFromBarButtonItem:permittedArrowDirections:animated:;
20. If you want to render from a view, use:
22. PresentPopoverFromRect:inView:permittedArrowDirections:animated:
26. If the device is rotated, the position positioning error needs to be repositioned in the following method of the parent view controller:
28. Didrotatefrominterfaceorientation: (re-set rect inside this method body)
30. Then call again:
32. -(void) Presentpopoverfromrect: (cgrect) rect inview: (UIView *) View permittedarrowdirections: ( Uipopoverarrowdirection) arrowdirections animated: (BOOL) animated
34. */
36. //uipopovercontroller can only be used on ipad devices, and is used to display temporary content that is always displayed at the front of the current view and disappears automatically when clicked elsewhere in the interface.
38. Uipopovercontroller *popover = [[Uipopovercontroller alloc]initwithcontentviewcontroller:picker];
40. Self.imagepicker = PopOver;
42. //permittedarrowdirections Setting the arrow direction
44. [Self.imagepicker presentpopoverfromrect:cgrectmake (0, 0, +) InView:self.view permittedarrowdirections: Uipopoverarrowdirectionany Animated:yes];
46. [Picker release];
48. [PopOver release];
