Mostrar un UIPickerView con UIActionSheet en iOS8 no funciona
uialertcontroller actionsheetpicker (8)
De la referencia para UIActionSheet:
UIActionSheet no está diseñado para ser subclasificado, ni debe agregar vistas a su jerarquía. Si necesita presentar una hoja con más personalización que la que proporciona la API UIActionSheet, puede crear la suya propia y presentarla de manera modal con presentViewController: animated: completion :.
Mi suposición es que veas exactamente por qué.
La referencia para UIAlertController no tiene un descargo de responsabilidad similar, pero mirando su interfaz, supongo que Apple lo agregará antes del lanzamiento.
Mi recomendación sería crear una vista pequeña que contenga el selector y los botones y mostrarla y ocultarla según sea necesario. No es tan difícil de hacer y no empuja las interfaces más allá de sus usos previstos.
Mostrar un UIPickerView con UIActionSheet en iOS8 no funciona
El código funciona en iOS7 , sin embargo, no funciona en iOS8 . Estoy seguro de que es porque UIActionSheet está en desuso en iOS8 y Apple recomienda usar UIAlertController .
Sin embargo, ¿cómo hacerlo en iOS8 ? Debería usar UIAlertController ?
iOS7 :
iOS8 :
EDITAR:
Escribo el selector de tiempo solo en lugar de UIActionSheet en iOS8:
date = [NSDate date];
timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 44, 0, 0)];
timePicker.datePickerMode = UIDatePickerModeDateAndTime;
timePicker.hidden = NO;
timePicker.date = date;
displayFormatter = [[NSDateFormatter alloc] init];
[displayFormatter setTimeZone:[NSTimeZone localTimeZone]];
[displayFormatter setDateFormat:@"MM月dd日 EEE HH:mm"];
formatter = [[NSDateFormatter alloc] init];
[formatter setTimeZone:[NSTimeZone localTimeZone]];
[formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
startDisplayTimeString = [displayFormatter stringFromDate:timePicker.date];
startTimeString = [formatter stringFromDate:timePicker.date];
NSTimeInterval interval = 24*60*60*1;
NSDate *endDate = [[NSDate alloc] initWithTimeIntervalSinceNow:interval];
endDisplayTimeString = [displayFormatter stringFromDate:endDate];
endTimeString = [formatter stringFromDate:endDate];
[_startTimeLabel setText:startDisplayTimeString];
[_endTimeLabel setText:endDisplayTimeString];
[pickerViewPopup dismissWithClickedButtonIndex:1 animated:YES];
NSDateFormatter *dateFormatter =[[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
pickerToolbar.tintColor = [UIColor whiteColor];
[pickerToolbar sizeToFit];

He enfrentado el mismo problema y lo resolvió de esta manera, funcionará en todas las versiones de ios
En ios 8 apple ha cambiado tantas cosas que aquí he enfrentado un problema en mi propio proyecto, así que solo quiero ofrecer la solución en reemplazo de UIActionsheet .
en ios 8 UIActionsheet obsoleto y sus métodos de delegado también se desaprobaron. En lugar de ese UIAlertController con UIAlertController
Se utiliza UIAlertControllerStyleActionSheet . puedes verificar este hilo también:
https://developer.apple.com/library/ios/documentation/Uikit/reference/UIActionSheet_Class/index.html
Este ejemplo funcionará tanto en ios 8 como en la versión anterior de este.
en el archivo .h declara esta variable

Intenta usar esta simulación de hoja de acción:

[simulatedActionSheetView setBackgroundColor:[UIColor clearColor]];
CGFloat pickerViewYpositionHidden = UIScreen.mainScreen.bounds.size.height + pickerToolbar.frame.size.height;

Mira mi código
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil
message:@"/n/n/n/n/n/n/n/n/n/n/n" preferredStyle:UIAlertControllerStyleActionSheet];
__weak typeof(self) weakSelf = self;
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"确认"style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
[weakSelf pickActionSheetFinishAction];
[alertController addAction:cancelAction];
[alertController.view addSubview:self.topicPickView];
[self presentViewController:alertController animated:YES completion:nil];
Para lograr el mismo efecto visual, puede usar ActionSheetPicker-3.0 , que funciona con iOS 8 .
En realidad, ya no es UIActionSheet . Pero se ve exactamente igual, y es por eso que funciona en iOS 8 .
Tengo el mismo problema contigo, mostrar un UIPickerView con UIActionSheet no funciona en iOS 8. Debido a que UIActionSheet está en desuso y Apple recomienda usar UIAlertController. Entonces deberíamos redondear al viento.
Escribí un código para resolver mi caso. Espero que pueda ayudarte.

[sheet.view setBounds:CGRectMake(7, 0, aWidth, CONTENT_HEIGHT)]; // Kinda hacky
self.sheet = sheet;
} else {

Creo que es todo para solucionar este problema. Feliz codificación!
UIActionSheet está privado de iOS8 . Use UIAlertController para iOS8 o posterior
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
message:@"This is an action shhet."
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction* cameraAction = [UIAlertAction actionWithTitle:@"Take A Photo" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
UIAlertAction* galleryAction = [UIAlertAction actionWithTitle:@"From Gallery" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {}];
UIAlertAction * defaultAct = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {}];
[alert addAction:cameraAction];
[alert addAction:galleryAction];
[alert addAction:defaultAct];
[self presentViewController:alert animated:YES completion:nil];
