自定義提醒框或下拉菜單及其使背景變暗

由於是自定義的因此我只把自定義的view顯示出來了,自定義的view只要邏輯是對的通常都不會錯(本例中第一個是三個控件加兩條線,第二個是一個tableview),若是對自定義的view有疑問可message me.ide

UIView *bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];3d

    bgView.backgroundColor = [UIColor colorWithWhite:0.f alpha:0.5];//使背景變暗orm

    [self.view addSubview:bgView];rem

    

    InputAlertView *alertView = [[InputAlertView alloc] initWithFrame:CGRectMake(40, 0.3*SCREEN_HEIGHT, SCREEN_WIDTH-80, 150)];get

    [bgView addSubview:alertView];input

    [[[UIApplication sharedApplication]keyWindow] addSubview:bgView];//使其導航欄也變暗it

    alertView.layer.cornerRadius = 5;io

    alertView.layer.masksToBounds = YES;

    alertView.backgroundColor = [UIColor whiteColor];

    alertView.alpha = 1.0;

    alertView.inputPwdTF.placeholder = @"請輸入管理員密碼";

    alertView.changeInfoLabel.text = @"修改員工信息請輸入管理員密碼";

    [alertView.okBtn setTitle:@" " forState:UIControlStateNormal];

    [alertView.okBtn bk_addEventHandler:^(id sender) {

        [bgView removeFromSuperview];//不用時要移除

        MCChangeWorkerInfoViewController *changeInfoVC = [MCChangeWorkerInfoViewController new];

        [self.navigationController pushViewController:changeInfoVC animated:YES];

    } forControlEvents:UIControlEventTouchUpInside];



自定義tableview型的下拉框效果圖:

相關代碼:

 

    [[[UIApplication sharedApplication]keyWindow] addSubview:bgView];


    //  自定義的tableView 提示框

    alertTableView *alertview = [[alertTableView alloc] initWithFrame:CGRectMake(60, 0.3*SCREEN_HEIGHT, SCREEN_WIDTH-120, 250) style:UITableViewStyleGrouped];

    alertview.titleArr = @[ @"最近7",@"最近15",@"最近一月",@"本季度",@"今年"];

    [bgView addSubview:alertview];


使背景變暗透明並使自定義的view背景不透明的方法我找到了兩種,代碼中用了一種,另外一種以下:

    UIColor *color = [UIColor BlackColor];

    bgView.backgroundColor = [color colorWithAlphaComponent:0.5];
