我希望为local notification
增加自定义铃声的时间,但
声音文件的长度必须小于30秒。如果声音文件超过30秒,系统将播放默认声音。 的
但我的声音文件是5分钟
我试过这样的方式:
content.sound = [soundName:@"mycustomtone.aiff"];
content.time = [timeDuration: 300];
我知道300秒超过30秒,这不是定义时间的正确方法,因为通知时间没有时间定义。
如果可能,请帮助我将自定义声音的持续时间延长30秒以上!
我知道没有什么是不可能的如果开发人员想要的话!
这是我正在做的事情:
#import "ViewController.h"
@interface ViewController () {
NSUserDefaults *defaults;
}
@end
bool isGrantedNotificationAccess;
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
isGrantedNotificationAccess = false;
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNAuthorizationOptions options = UNAuthorizationOptionAlert+UNAuthorizationOptionSound;
[center requestAuthorizationWithOptions:options completionHandler:^(BOOL granted, NSError * _Nullable error) {
isGrantedNotificationAccess = granted;
}];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)notifyButton:(id)sender {
if (isGrantedNotificationAccess) {
NSLog(@"clicked");
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = @"Notification Title";
content.subtitle = @"Notification Subtitle";
content.body = @"Notification body";
content.sound = [UNNotificationSound soundNamed:@"alarm_clock_2015.aiff"];
content.timeDuration = 300;
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"UYLocalNotification" content:content trigger:trigger];
[center addNotificationRequest:request withCompletionHandler:nil];
}
}
@end

正如你所说:
声音文件的长度必须少于30秒。如果是声音文件 超过30秒,系统会播放默认声音。
我鼓励您考虑到这一点,因为即使您设法欺骗并解决问题,Apple也会拒绝您的应用。
除此之外,5分钟不是声音,它是音乐,所以要在应用程序处于后台时播放应用程序,您必须注册为音频应用程序,并在收到通知后,使用AVAudioPlayer播放您的文件。

我会试一试,但我无法测试这段代码,但我会粗略地解释一下我将如何做这个...(不知道这是否会起作用) )
我会创建一个像这样的函数:
-(void)playsound {
[[NSSound soundNamed:@"alarm_clock_2015"] play];
}
并从notifyButton IBAction
- (IBAction)notifyButton:(id)sender {
if (isGrantedNotificationAccess) {
NSLog(@"clicked");
[self playsound];
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
//Mute the sound of this notification
content.title = @"Notification Title";
content.subtitle = @"Notification Subtitle";
content.body = @"Notification body";
content.sound = [UNNotificationSound soundNamed:@"alarm_clock_2015.aiff"];
//content.timeDuration = 300;
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"UYLocalNotification" content:content trigger:trigger];
[center addNotificationRequest:request withCompletionHandler:nil];
}
}
