EmotionKeyboard *emotionKeyboard = [[EmotionKeyboard alloc]initWithFrame:CGRectMake(0, ScreenH - 235, ScreenW, 235)];

EmotionKeyboard *emotionKeyboard = [[EmotionKeyboard alloc]init];

EmotionKeyboard *emotionKeyboard = [[EmotionKeyboard alloc]initWithDefault];

EmotionKeyboard *emotionKeyboard = [EmotionKeyboard sharedEmotionKeyboardView];

  • initWithFrame: 可自己指定键盘大小 已经做适配 默认为有四个选项

  • init: 默认Frame为 CGRectMake(0, ScreenH - 216, ScreenW, 216) 默认为有四个选项

  • sharedEmotionKeyboardView:单利模式 默认Frame为 CGRectMake(0, ScreenH - 216, ScreenW, 216) 默认为有四个选项

  • initWithDefault: 默认Frame为 CGRectMake(0, ScreenH - 216, ScreenW, 216) 只有默认的小表情


    • 默认创建大小自己可修改

    + (void)addCollectImage:(NSString *)url;

    //使用
     [EmotionTool addCollectImage:url];

    如果需要替换默认表情,请替换资源文件. 并按照对应要去修改资源目录下info.plist文件
