添加UITableViewController下的純代碼按鍵

-(void)binge_addSendBtns {
    // 設(shè)置按鍵位置的參數(shù)
    CGFloat viewW = self.view.bounds.size.width;
    UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, viewW, 200)];
    // 設(shè)置 footerView
    self.tableView.tableFooterView = footerView;
    
    UIButton *sendMsgBtn = [[UIButton alloc]init];
    [sendMsgBtn addTarget:self action:@selector(sendMsg) forControlEvents:UIControlEventTouchUpInside];
    // 按鍵顏色
    [sendMsgBtn setBackgroundColor:[UIColor colorWithRed:50.0/255 green:180.0/255 blue:50.0/255 alpha:1]];
    // 按鍵文字顏色
    [sendMsgBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    // 按鍵標(biāo)題
    [sendMsgBtn setTitle:@"發(fā)消息" forState:UIControlStateNormal];
    // 按鍵位置
    sendMsgBtn.frame = CGRectMake(20, 0, viewW - 40, 44);
    // 圓角
    sendMsgBtn.layer.cornerRadius = 10;
    // 切除/覆蓋多余的
    sendMsgBtn.layer.masksToBounds = YES;
//    [self.view addSubview:sendMsgBtn];
    [footerView addSubview:sendMsgBtn];
}

    [super viewDidLoad];
    //調(diào)用方法
