ios - 按下图像按钮时添加声音

Question

我在 ScrollView 中有这个按钮，我需要在按下它时播放声音。

UIButton *profileButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [profileButton setImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateNormal];
    [profileButton setImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateHighlighted];
    profileButton.frame = CGRectMake(0, 620, 320, 250);

[self.scrollView addSubview:profileButton];

我怎样才能做到这一点？谢谢，

Answer 1

添加按钮按下触摸

[profileButton addTarget:self action:@selector(onButtonPress) forControlEvents:UIControlEventTouchUpInside];

//需要此包含文件和 AudioToolbox 框架

#import <AudioToolbox/AudioToolbox.h>

播放一些声音

-(void) onButtonPress {
    NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"mp3"];
    SystemSoundID soundID;
    AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath: soundPath], &soundID);
    AudioServicesPlaySystemSound (soundID);
}
