10个控件

label

button

view

imageview

textfield

textview

interface build IBOutlet 界面显示

IBAction 和void一个类型

计步器

UIStepper * stepper

进度条

UIProgressView * progress

警告框

1、添加的警告框的标题

2、警告框的内容

3、设置代理一般设置当前类的对象指针为UIAlertView的代理

4、设置按钮的标题此处的标题一般的时候不缺省

5、设置多个按钮标题

UIAlertView * alertview = [[UIAlertView alloc]initWithTitle:@"警告" message:@"你很帅" delegate:self cancelButtonTitle:@"我知道了" otherButtonTitles:@"呵呵", nil];

//alerview 就是与用户交互的警告框

//buttonIndex 警告框上的按钮的下标值(从左向右，或者从上向下，下标值逐渐加1)

//cancelButton 的下标值永远为0

提示框

//destructiveButton 的下标值为0 ，按钮从上到下，下标值逐个加1

UIActionSheet * sheet = [[UIActionSheet alloc]initWithTitle:@"上传图片信息" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles:@"拍照",@"从相册中获取",@"从本地获取", nil];

//将提示框添加到视图上面

分段控件对象

NSArray * arr = @[@"red",@"green",@"blue"];

UISegmentedControl * segmentcontrol = [[UISegmentedControl alloc]initWithItems:arr];

segmentcontrol.frame = CGRectMake(10, 100, 300, 40);

创建滑动块

UISlider * slider = [[UISlider alloc]initWithFrame:CGRectMake(10, 100, 300, 10)];

网页视图WEBview

UIWebView * webview = [[UIWebView alloc]initWithFrame:CGRectMake(0, 50, 320, 480-50)];

创建开关控件对象及活动指示器

UISwitch * swtichview = [[UISwitch alloc]initWithFrame:CGRectMake(100, 100, 100, 40)];
 //活动指示器不能与用户进行交互
    //经常用于显示加载中
    //<1>创建活动指示器对象
    /*
     UIActivityIndicatorViewStyleWhiteLarge,
     UIActivityIndicatorViewStyleWhite,
     UIActivityIndicatorViewStyleGray
     */
    UIActivityIndicatorView * activity = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; //活动指示器

创建选择器控件UIPickerView

picker = [[UIPickerView alloc]initWithFrame:CGRectMake(0, 230, 320, 480-230)];

picker.backgroundColor = [UIColor greenColor];

//设置代理必须设置代理，不然无法传值

picker.delegate = self;

picker.dataSource = self;

计步器

//<1>创建计步器对象
    UIStepper * stepper = [[UIStepper alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
