之前做过一个访微信头像的功能，现在贴出代码

先在工程里放入对应的头像，然后装入一个数组传入方法里，接着画好xib对应的9宫格头像，里面用到了2个库，大家可以去网上下载

- (void)viewDidLoad{    [super viewDidLoad];    //需要传入一个数组，arr.count对应头像数量，最多显示9个    NSMutableArray *array = [[NSMutableArray alloc]initWithCapacity:0];    [array addObject:@"1"];    [array addObject:@"2"];    [array addObject:@"3"];    [array addObject:@"5"];    [array addObject:@"9"];        //加方法调用群组头像功能    SudokuRoundView *view = [SudokuRoundView createSudokuRoundViewWithFrame:CGRectMake(20, 110, 70, 70) WithXIBSubImageViewArray:array WithMessageNotRead:0];    [self.view addSubview:view];}

/** 9宫格xib加方法 *  frame : 图片范围 *  array : 图像数据数组 *  message : 未读消息数字 */+ (SudokuRoundView *)createSudokuRoundViewWithFrame:(CGRect)frame WithXIBSubImageViewArray:(NSMutableArray *)array WithMessageNotRead:(int)messgae{        int maxNum = 0;    //判断最多9个头像    if (array.count > 9) {        maxNum = 9;    }else{        maxNum = array.count;    }        //加载对应的xib    SudokuRoundView *sudokuRoundView = [self initWithSudokuRoundView:maxNum -1];    if (array.count) {        [sudokuRoundView initWithTag:maxNum *100 WithFrame:frame WithArray:array WithMessageNotRead:messgae];    }        return sudokuRoundView;}

//返回对应实例+ (SudokuRoundView *)initWithSudokuRoundView:(int)object{    return [[[NSBundle mainBundle]loadNibNamed:@"SudokuRoundView" owner:self options:nil]objectAtIndex:object];}

//加载图片- (void)initWithTag:(int)tag WithFrame:(CGRect)frame WithArray:(NSMutableArray *)array WithMessageNotRead:(int)messgae{        //初始化数据    [self makeView:frame];        for (NSString *imageStr in array) {                static int i = 0;                UIImageView *imageView = (UIImageView *)[self viewWithTag:tag+i];        //SDWebImage的方法        [imageView setImageWithURL:nil placeholderImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@",imageStr]]];                //badge图标        JSBadgeView *badgeView = [[JSBadgeView alloc] initWithParentView:self alignment:JSBadgeViewAlignmentTopRight];                badgeView.badgeText = [NSString stringWithFormat:@"%d", messgae];        i ++;                //超过9次放弃加载        if (i>=9) {            break;        }    }}
