我们都知道，UIButton的点击事件：添加一个addtarget,然后选择点击触发：UIControlEventTouchUpInside，就可以实现Btn的点击事件。...imageView的点击事件 -->探究3：为啥ImageView 没有 UIbutton 的addtarget方法？ ?...addTarget方法底层 如图，我们发现addTarget并不是所有的类都有这个方法-->只有UIControl的子类才能有这个方法！ ?...UIButton继承自UIControl，所以有addTarget方法 ?...UIImageView不继承UIControl，所以没有addTarget方法 -->探究4：没有addTarget方法的ImageView如何添加点击事件？ 答：使用手势。 ?
//按钮初始化类方法 UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];//这里创建一个圆角矩形的按钮 //按钮初始化实例方法...触发了这个事件以后，执行butClick:这个方法，addTarget:self 的意思是说，这个方法在本类中也可以传入其他类的指针 [button1 addTarget:self action:@selector...forControlEvents:UIControlEventTouchUpInside]; //显示控件 [self.view addSubview:button1]; 注意： [button1 addTarget...:self action:@selector(alarmTimeDone:) forControlEvents:UIControlEventTouchUpInside]; addTarget:self...是否在dealloc中对UIButton对象进行release操作，取决于UIButton初始化的方式。

打开viewController.m创建两个UIButton: @interface ViewController () @property (nonatomic, strong) UIButton *...CGRectMake(0, 60, 100, 100); _leftBtn.backgroundColor = [UIColor blueColor]; [_leftBtn addTarget...kScreenWidth - 100, 60, 100, 100); _rightBtn.backgroundColor = [UIColor blueColor]; [_rightBtn addTarget...第二步，实现弹出控制器： 现在我们给左右按钮addTarget。...strong) UIViewController *currentVC; @property (nonatomic, strong) TestOneViewController *leftVC; // 移除掉不活动的
我们新建一个NewViewController，在开始的ViewController写如下代码 - (void)viewDidLoad { [super viewDidLoad]; UIButton...*btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.frame = CGRectMake(100, 100, 100, 50);...btn.backgroundColor = [UIColor brownColor]; [btn addTarget:self action:@selector(jump) forControlEvents...btn.backgroundColor = [UIColor brownColor]; [btn addTarget:self action:@selector(jump) forControlEvents...btn.backgroundColor = [UIColor brownColor]; [btn addTarget:self action:@selector(jump) forControlEvents

UIButton一般分为高亮的普通两种状态，原生的方法可以设置这两种不同状态下的文字颜色，文字内容，背景图片，按钮图片。但是不能设置按钮的背景色。...方法一：通过按钮的事件来设置背景色 - (void)viewDidLoad { [super viewDidLoad]; UIButton *button1 = [[UIButton..." forState:UIControlStateNormal]; button1.backgroundColor = [UIColor orangeColor]; [button1 addTarget...action:@selector(button1BackGroundHighlighted:) forControlEvents:UIControlEventTouchDown]; [button1 addTarget...*button2 = [[UIButton alloc] initWithFrame:CGRectMake(170, 200, 100, 50)]; [button2 setTitle:@"button2
如果不是敲错IP、用户名、密码，报凭据不工作，一般情况下执行这几句命令后重启远程服务就正常了第1句：REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT...用户名或密码敲错了或复制粘贴的时候带了多余的字符，或者键盘兼容性问题，我曾遇到过横排数字键和右侧数字键区，按键不符合预期的情况（可能没按出来值，也可能按出来跟预期的值不一样）2、用户名、密码正确，通过vnc能进入系统，通过远程就是报凭据不工作上次我遇到个
