效果图
##import "ViewController.m" PlaceholderTextView* titleTexView; // placeHolder的textView， PlaceholderTextView* contentTextView; showVideoView* showVideo; //添加照片、视频、语音按钮
使用 PlaceholderTextView
titleTexView = [[PlaceholderTextView alloc]initWithFrame:CGRectMake(12, 10, kScreenWidth-24, 35)];
titleTexView.delegate = self;
titleTexView.font = [UIFont systemFontOfSize:15.f];
titleTexView.textColor = [UIColor blackColor];
titleTexView.textAlignment = NSTextAlignmentLeft;
titleTexView.editable = YES;
titleTexView.placeholderColor = [UIColor darkTextColor];
titleTexView.placeholder = @"标题（必填）";
[showScrollView addSubview:titleTexView];
showVideoView
showVideo = [[showVideoView alloc]initWithFrame:CGRectMake(0, contentTextView.frame.origin.y+contentTextView.frame.size.height+5, kScreenWidth, 78)];
[showScrollView addSubview:showVideo];

###视频 #pragma mark 🎱添加视频
- (void)_addVideoButtonAction:(UIButton*)sender{
KZVideoViewController *videoVC = [[KZVideoViewController alloc] init];
videoVC.delegate = self;
[videoVC startAnimationWithType:KZVideoViewShowTypeSingle];
}
实现KZVideoViewControllerDelegate
#pragma mark 🎱 视频录制或选择后回调
- (void)videoViewController:(KZVideoViewController *)videoController didRecordVideo:(KZVideoModel *)videoModel{
// [self refreshButtonFrame];
// _addVideoButton.hidden = YES;
// [self delete_addVideoButton];
[circleCollectionView reloadData];

###语音
定时60S，可修改 //录音储存路径

[_addRecordButton addTarget:self action:@selector(cancelRecordVoice) forControlEvents:UIControlEventTouchUpOutside];// 取消录音
[_addRecordButton addTarget:self action:@selector(confirmRecordVoice) forControlEvents:UIControlEventTouchUpInside];// 录音结束
[_addRecordButton addTarget:self action:@selector(updateCancelRecordVoice) forControlEvents:UIControlEventTouchDragExit]; // 更新录音显示状态,手指向上滑动后 提示松开取消录音

将生成的caf格式的视频转换成mp3格式，方便与安卓共用，但是会有比较严重的失真，如果安卓不是需求尽量不要转
- (NSString*)formatConversionToMp3{
NSString *cafFilePath = self.messageModel.soundFilePath; //caf文件路径
NSString* fileName = [NSString stringWithFormat:@"/voice-%5.2f.mp3", [[NSDate date] timeIntervalSince1970] ];//存储mp3文件的路径
NSString *mp3FilePath = [[DocumentPath stringByAppendingPathComponent:@"SoundFile"] stringByAppendingPathComponent:fileName];
@try {
CGFloat read, write;
FILE *pcm = fopen([cafFilePath cStringUsingEncoding:1], "rb"); //source 被转换的音频文件位置
fseek(pcm, 4*1024, SEEK_CUR); //skip file header
FILE *mp3 = fopen([mp3FilePath cStringUsingEncoding:1], "wb"); //output 输出生成的Mp3文件位置
const int PCM_SIZE = 8192;
const int MP3_SIZE = 8192;
short int pcm_buffer[PCM_SIZE*2];
unsigned char mp3_buffer[MP3_SIZE];
lame_t lame = lame_init();
lame_set_in_samplerate(lame, 11025.0);
lame_set_VBR(lame, vbr_default);
lame_init_params(lame);
do {
read = fread(pcm_buffer, 2*sizeof(short int), PCM_SIZE, pcm);
if (read == 0)
write = lame_encode_flush(lame, mp3_buffer, MP3_SIZE);
else
write = lame_encode_buffer_interleaved(lame, pcm_buffer, read, mp3_buffer, MP3_SIZE);
fwrite(mp3_buffer, write, 1, mp3);
} while (read != 0);
lame_close(lame);
fclose(mp3);
fclose(pcm);
}
@catch (NSException *exception) {
NSLog(@"%@",[exception description]);
}
@finally {
}
// 将caf 文件删除
[[NSFileManager defaultManager] removeItemAtPath:self.messageModel.soundFilePath error:nil];
NSLog(@"mp3FilePath :: :::::≥≥≥®%@",mp3FilePath);
return mp3FilePath;
}
#TIP: 之前设定的是照片和视频不能同时发布，但是布局和逻辑已经做好了，如果需要可以修改showVideoView.m中
- (void)setIsPhoto:(BOOL)isPhoto;
//添加视频按钮可以使用
_addVideoButton.enabled = NO;
[_addVideoButton setImage:[UIImage imageNamed:@"second_video_s"] forState:UIControlStateNormal];
注释掉就可以了
