    UIView *ShareView=[[UIViewalloc] initWithFrame:CGRectMake(0,0, 440, 976)];

    

    UIImageView *ShareViewBG=[[UIImageViewalloc] initWithImage:backImage];

    [ShareView addSubview:ShareViewBG];

    

    UIImageView *HeadView=[[UIImageViewalloc] initWithFrame:CGRectMake(30,430, 70, 70)];

    HeadView.image=[UIImageimageWithData:[NSDatadataWithContentsOfURL:[NSURLURLWithString:profileImageUrl]]];

    [ShareView addSubview:HeadView];

    

    UILabel *usernameLabel=[[UILabelalloc] initWithFrame:CGRectMake(110,480, 100, 20)];

    usernameLabel.text=username;

    usernameLabel.font=[UIFontsystemFontOfSize:22.0];

    usernameLabel.backgroundColor=[UIColorclearColor];

    [ShareView addSubview:usernameLabel];

    

    UIGraphicsBeginImageContext(ShareView.bounds.size);

    

    [ShareView.layerrenderInContext:UIGraphicsGetCurrentContext()];

    

    UIImage*image =UIGraphicsGetImageFromCurrentImageContext();

    

    UIGraphicsEndImageContext();
