我有 2 个 ViewController，每个都有几个按钮来播放和停止音频。此音频已部署在单独的模型中，以便能够从两个 ViewController 访问，但我不知道这是否是正确的方式......
#import <UIKit/UIKit.h>
#import "AudioController.h"
@interface NowViewController : UIViewController
@property (nonatomic, strong) AudioController *AudioModel;
- (IBAction)PauseButton:(UIButton *)sender;
- (IBAction)PlayButton:(UIButton *)sender;
@end
#import "NowViewController.h"
@interface NowViewController ()
@end
@implementation NowViewController
- (void)viewDidLoad{
[super viewDidLoad];
self.AudioModel = [[AudioController alloc] init];
}
- (IBAction)PlayButton:(UIButton *)sender {
[self.AudioModel PlayAudio];
}
- (IBAction)PauseButton:(UIButton *)sender {
[self.AudioModel PauseAudio];
}
@end
#import <UIKit/UIKit.h>
#import "AudioController.h"
@interface CategoriesViewController : UIViewController
@property (nonatomic, strong) AudioController *AudioModel;
- (IBAction)PauseButton:(UIButton *)sender;
- (IBAction)PlayButton:(UIButton *)sender;
@end
#import "NowViewController.h"
@interface NowViewController ()
@end
@implementation NowViewController
- (void)viewDidLoad{
[super viewDidLoad];
self.AudioModel = [[AudioController alloc] init];
}
- (IBAction)PlayButton:(UIButton *)sender {
[self.AudioModel PlayAudio];
}
- (IBAction)PauseButton:(UIButton *)sender {
[self.AudioModel PauseAudio];
}
@end
我遇到的问题是，如果我从一页播放音频并导航到另一页，那么我无法停止音频。同样，我无法从多任务中播放/暂停。这是 AudioModel 的代码：
#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>
@interface AudioController : NSObject{
AVPlayer *Player;
}
- (void)PlayAudio;
- (void)PauseAudio;
@end
#import "AudioController.h"
@implementation AudioController
- (void)PlayAudio {
Player = [[AVPlayer alloc] initWithURL:[NSURL URLWithString:url]];
[Player play];
}
- (void)PauseAudio {
[Player pause];
}
NSString *url = @"http://jo.my/xxx";
@end
谢谢您的帮助！
