设置表情键盘视图

有时候开发的时候可能需要做表情键盘，以前都是网上找的demo很多时候并不能很好的适合自己要做的开发项目，就想着自己写一个表情键盘的视图，代码如下。

NSMutableArray *temp = [[NSMutableArray alloc] init];

    for (int i = 0;i<105;i++){

        //取出图片的UIImage

        UIImage *face = [UIImage imageNamed:[NSString stringWithFormat:@"%d.png",i]];

        NSMutableDictionary *dicFace = [NSMutableDictionary dictionary];

        [dicFace setValue:face forKey:[NSString stringWithFormat:@"[/%d]",i]];

        

        [temp addObject:dicFace];

    }

    self.phraseArray = temp;
//将表情包导入工程之后，可以将表情包这样取出来放到数组里暂时保存起来，在表情键盘呼出时再将需要的表情，便历出来加载到表情键盘上

//键盘视图加载似的方法- (void)showEmojiView{

   

    int xIndex = 0;

    

    int yIndex = 0;

   

    int emojiRangeArray[12] = {0,10,20,30,40,50,60,70,80,90,100,104};

   

    for (int j = 0 ; j<12 ; j++ ) {

       

        int startIndex = emojiRangeArray[j];

        

        int endIndex = emojiRangeArray[j+1];

       

        for (int i = startIndex ; i<= endIndex ; i++ ) {

            

            UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

            

            button.frame = CGRectMake(10 + xIndex*32, 10 + yIndex*32, 32.0f, 32.0f);

            NSMutableDictionary *tempdic = [self.phraseArray objectAtIndex:i];

//            if (i<10){

//            UIImage *tempImage = [tempdic valueForKey:[NSString stringWithFormat:@"</00%d>",i]];

//            [button setBackgroundImage:tempImage forState:UIControlStateNormal];

//            } else if (i<100){

//                UIImage *tempImage = [tempdic valueForKey:[NSString stringWithFormat:@"</0%d>",i]];

//                [button setBackgroundImage:tempImage forState:UIControlStateNormal];

//            }else

//            {

                UIImage *tempImage = [tempdic valueForKey:[NSString stringWithFormat:@"[/%d]",i]];

                [button setBackgroundImage:tempImage forState:UIControlStateNormal];

//            }

            button.tag = i;

            

            [button addTarget:self action:@selector(didSelectAFace:)forControlEvents:UIControlEventTouchUpInside];

            

            [_faceScrollView addSubview:button];

           

            xIndex += 1;

            

            if (xIndex == 9) {

                

                xIndex = 0;

                

                yIndex += 1;

                

            }

            

        }

        

    }

    

    [_faceScrollView setContentSize:CGSizeMake(300.0f, 12 + (yIndex+1)*32)];

}

//点击表情时调用的方法

-(void)didSelectAFace:(id)sender

{

    UIButton *tempbtn = (UIButton *)sender;

    NSMutableDictionary *tempdic = [self.phraseArray objectAtIndex:tempbtn.tag];

    NSArray *temparray = [tempdic allKeys];

    NSString *faceStr= [NSString stringWithFormat:@"%@",[temparray objectAtIndex:0]];

    

    self.chatViewController.phraseString = faceStr;

    [self.chatViewController.messageString appendString:self.chatViewController.phraseString];

    [self dismissModalViewControllerAnimated:YES];

}
