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];

###照片 #pragma mark 🎱 添加照片

默认6张，可以修改

- (void)addImageButtonAction:(UIButton*)sender

#pragma mark 🎱 显示照片

照片在Collection中显示，方便完成增删

collectionCell 中有普通照片、添加照片按钮、添加视频按钮，根据CircleCellModel中cirModelState属性判断对应的方法在其viewController里实现

- (void)addImageToshowCirclectionView:(NSArray*)imageArray{

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
