利用 AVAudioPlayer 来播放音乐 ：
- 声明对象
#import <AVKit/AVKit.h>
#import <AVFoundation/AVFoundation.h>
@property (nonatomic, strong) AVAudioPlayer *avAudioPlayer;
- 播放函数
NSURL *url = [[NSURLalloc] initWithString:[AppUtilurlEncodeToURLString:urlStr]];
NSData *audioData = [NSDatadataWithContentsOfURL:url];
_avAudioPlayer = [[AVAudioPlayeralloc] initWithData:audioData error:nil];
[_avAudioPlayerplay];
_avAudioPlayer.delegate = self;
_stringUrlAudio = urlStr;
<附加函数>
+ (NSString *)urlEncodeToURLString:(NSString *)urlString
{
if (IS_NS_STRING_EMPTY(urlString)) {
return@"";
}
NSString *encodingUrl = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
return encodingUrl;
}
- 代理函数
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[self.voiceImageViewstopAnimating];
self.weplayPage.avAudioPlayer = nil;
}
图标的播放时的动态效果代码如下：
- (UIImageView *)voiceImageView
{
if (!_voiceImageView) {
_voiceImageView = [[UIImageViewalloc] initWithFrame:CGRectMake(14, 0, 12, 12)];
_voiceImageView.centerY = self.soundImageView.bounds.size.height/2.0;
_voiceImageView.contentMode = UIViewContentModeScaleAspectFill;
NSArray *arr = @[@"ic_yiqiwan_details_play1",@"ic_yiqiwan_details_play2",@"ic_yiqiwan_details_play3"];
[self.soundImageViewaddSubview:_voiceImageView];
NSMutableArray *imageArray = [NSMutableArrayarray];
for (int i=0;i<arr.count;++i) {
UIImage *tmpimage = [UIImageimageNamed:arr[i]];
[imageArray cl_addObject:tmpimage];
}
_voiceImageView.animationImages = imageArray;
_voiceImageView.animationRepeatCount = 0;
_voiceImageView.animationDuration = 1.5;
_voiceImageView.image = [UIImageimageNamed:@"ic_yiqiwan_details_play3"];
//[_voiceImageView startAnimating];
}
return_voiceImageView;
}
动画效果如下：
