Are there examples of how to use UIPopoverController on iOS?

问题

I've seen some demos where UIPopoverController is used and would like to use it in my apps.

So does anyone have any good tutorials that you could link me?

Is it possible to use it in relation to UISegmentedControl where different popover windows are summoned when different segments are selected as a type of a switch view function?

Here are some tutorials:

For popover in iPad we can use ActionSheetStringPicker, and for implementing it in your project you need to import ActionSheetStringPicker into your controller. like - #imaport "ActionSheetStringPicker.h"
After importing this you have to create an array which has only string type value.

e.g.

   NSArray *sourceArray=[[NSArray alloc]initWithObjects:@"Take Photo",@"Choose Photo", nil];

And last you have to implement below method.

[ActionSheetStringPicker showPickerWithTitle:@"Any title"
                                            rows:sourceArray
                                initialSelection:yourInitialSelectionIntValue
                                       doneBlock:^(ActionSheetStringPicker *picker, NSInteger selectedIndex, id selectedValue) {

                                       NSLog(@" Index : %ld, value : %@",
                                             (long)selectedIndex, selectedValue);
                                       if ([selectedValue isEqualToString:@"Choose Photo"]) {

                                           // open photo lib
                                           [self youerMethdeOpenPhotoLib];

                                       }
                                       else
                                       {
                                           // open Camera
                                           [self yourMethodOpenCamera];
                                       }



                                   }
                                 cancelBlock:^(ActionSheetStringPicker *picker) {
                                     NSLog(@"Select photo Cancel");

                                 }origin:YourTapButtonObject];
