#import "ViewController.h"
    #import "EmojiEmoticons.h"
    
    @interface ViewController ()
    
    
    @property (weak, nonatomic) IBOutlet UITextView *faceTextField;
    
    
    
    @property (nonatomic,strong) NSArray *array;
    
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
       
        _array =  [EmojiEmoticons allEmoticons];
    }
    
    
    - (IBAction)faceBtnAction:(id)sender {
        
        int index = arc4random_uniform(20);
        NSLog(@"系统表情符号--->%@",[_array objectAtIndex:index]);
        
        _faceTextField.text = [_faceTextField.text stringByAppendingString:[_array objectAtIndex:index]];
    }
    
    
    @end
