This is easy to use demo about UIAlertController (preffered Style: ActionSheet) with code held in one file and access in all other views. This demo is avaialble in both programming lanauage Objective-C & Swift.
- Appears as the result of a user action
- Displays two or more buttons
Use an action sheet to:
-
Provide alternative ways to complete a task. An action sheet lets you to provide a range of choices that make sense in the context of the current task, without giving these choices a permanent place in the UI.
-
Get confirmation before completing a potentially dangerous task. An action sheet prompts users to think about the potentially dangerous effects of the step they’re about to take and gives them some alternatives.
- Xcode 10.0 or above
- Objective-C
- Swift 4.0 or above
- Development Target 10.0 or above
- Device Universal Supported
You just need to download this demo and run it inot SIMULATOR or REAL device whatever you want. OR Just copy and paste code from Utility.swift | Utility.h & Utility.m file into your projects and access it!
There are two different project in this repositor:
- Objective-C (Utility.h & Utility.m file)
typedef void (^ _Nullable completion)(int index);
+ (void)
shwoActionSheetInViewController: (UIViewController *)vc withTitle: (nullable NSString *)title andMessage: (nullable NSString *)message withButtons: (NSArray *)button cancelAvailable: (BOOL)isCancel withCompletion: (completion)completionBlock
{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleActionSheet];
for (int index = 0; index < button.count; index++) {
UIAlertAction *action = [UIAlertAction actionWithTitle:button[index] style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
if (completionBlock != nil) {
completionBlock(index);
}
}];
[alertController addAction:action];
}
if (isCancel) {
UIAlertAction *action = [UIAlertAction actionWithTitle:[NSString stringWithFormat:@"Cancel"] style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {
if (completionBlock != nil) {
completionBlock((int)[button count]);
}
}];
[alertController addAction:action];
}
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
// if device is iPhone
[vc presentViewController:alertController animated:YES completion:nil];
} else {
// if device is iPad
[alertController setModalPresentationStyle:UIModalPresentationPopover];
UIPopoverPresentationController *popoverController = [alertController popoverPresentationController];
[popoverController setSourceView:[vc view]];
[popoverController setSourceRect:CGRectMake(CGRectGetMidX([[vc view] bounds]), CGRectGetMidY([[vc view] bounds]), 0, 0)];
[popoverController setPermittedArrowDirections:UIPopoverArrowDirectionUnknown];
[vc presentViewController:alertController animated:YES completion:nil];
}
}- Swift (Utility.swift file)
static func shwoActionSheetInViewController(vc: UIViewController, withTitle title: String?, andMessage message: String?, withButtons button: [String], cancelAvailable isCancel: Bool, completion:((_ index: Int) -> Void)!) -> Void

}
})
alertController.addAction(action)
}
