IOS实现聊天界面底部菜单栏效果

-本安全出自个人小项目仿boss直聘当中的聊天信息界面：

实现的思路主要是：约束动画。

实现较简单，这里直接上代码：

。h文件：

#import <UIKit/UIKit.h> 
@protocol ShowMoreOptionListener <NSObject> 
@optional 
-(void) onChangListener; 
@end 
@class ScrollView; 
/** 
 底部菜单视图 
 */ 
@interface BottomMenuView : UIView 
@property(nonatomic,strong) UIView* showPartView;    //总是可见部分 
@property(nonatomic,strong) UIView* hiddenPartView;   //底部隐藏部分，需要点击显示部分才能显示出来 
@property(nonatomic,weak) id<ShowMoreOptionListener> delegate; //下面更多操作菜单的的状态代理器 
@property(nonatomic,strong) ScrollView* emojiPanel; 
-(void) buildOptionMenu; 
@end

.m文件：

#import "BottomMenuView.h" 
#import "Masonry.h" 
#import "QuickWordsView.h" 
#import "ScrollView.h" 
#import "Constants.h" 
static const int QuickChat = 31; 
static const int Emoji = 32; 
static const int AddType = 33; 
static const int EmojiPanel = 34; 
static const int QuickChatPanel = 34; 
@implementation BottomMenuView 
-(instancetype) initWithFrame:(CGRect)frame{

  return self; 
} 
-(void) buildOptionMenu{

  //self.showPartView.backgroundColor = [UIColor greenColor]; 
  [self addSubview:self.showPartView]; 
  //添加showPartView约束 
  [self.showPartView mas_makeConstraints:^(MASConstraintMaker *make) { 
    make.right.equalTo(self).offset(0); 
    make.top.equalTo(self);

//更多操作按钮的协议监听接口 
-(void)onChangListener{

  if(self.bottomHeightCons.constant == 40){ 
    self.bottomHeightCons.constant = 260; 
  }else{ 
    self.bottomHeightCons.constant = 40; 
  } 
  [UIView animateWithDuration:0.5 animations:^{ 
    [self.view layoutIfNeeded]; 
  }];    
}
