屏幕快照 2016-08-30 13.53.37.png 其实也非常简单 **1、定于两个属性按钮** @property (nonatomic, strong) UIButton * sinaButton...setBackgroundImage:[UIImage imageNamed:@"invest_selecte"] forState:(UIControlStateSelected)]; [_sinaButton addTarget...UIControlStateNormal)]; [sinaNme setTitleColor:[UIColor blackColor] forState:(UIControlStateNormal)]; [sinaNme addTarget...setBackgroundImage:[UIImage imageNamed:@"invest_selecte"] forState:(UIControlStateSelected)]; [_bankButton addTarget...banknameSelete setTitleColor:[UIColor blackColor] forState:(UIControlStateNormal)]; [banknameSelete addTarget
//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。
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。 ?

最近项目上需要用到一个选择器，选择器中的内容只有年和月，而在iOS系统自带的日期选择器UIDatePicker中却只有四个选项如下，分别是时间（时分秒）、日期（年月日）、日期+时间（年月日时分）以及倒计时...首先，我们来看一下整体的一个效果，点击某个设定的控件，然后弹出下图所示的一个选择器，选择器的选项主要就是显年月的信息： ?...UIControlStateNormal]; 72 [_leftBtn setTitle:@"取消" forState:UIControlStateNormal]; 73 [_leftBtn addTarget...UIControlStateNormal]; 87 [_rightBtn setTitle:@"确定" forState:UIControlStateNormal]; 88 [_rightBtn addTarget...添加分割线 [self.topView addSubview:self.lineView]; } 二是我们的背景蒙层和弹出视图大家可以通过代码看到蒙层遮罩背景的布局是整个屏幕，那么我们为什么不直接在蒙层上添加弹出式图呢

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
一、准备工作 unity导出的xcode项目 二、开始倒腾 1、将Unity3D中的以下文件导入到工程目录下 Data Classes MapFileParser.sh Libraries MapFileParser...* btn = [[UIButton alloc] initWithFrame:CGRectMake(50, 400, 100, 50)]; [btn addTarget:self action..."开始" forState:UIControlStateNormal]; btn.tag = 1; [self.view addSubview:btn]; UIButton...* btn2 = [[UIButton alloc] initWithFrame:CGRectMake(50, 450, 100, 50)]; [btn2 addTarget:self action...unity保持一致 Framework Search Paths 和unity保持一致 Other linker Flags 和unity保持一致 all_load 如果项目中有这个 记得删除 和unity不兼容
