UI基础:UIActionSheet和UIAlterView

iOS中有两个弹出视图的控件,分别是UIActionSheet和UIAlterView.效果图如下:

     

主要代码如下:

 - (void)viewDidLoad {

     [super viewDidLoad];

     // Do any additional setup after loading the view, typically from a nib.

     UIButton * button1 = [UIButton buttonWithType:UIButtonTypeCustom];

     button1.frame = CGRectMake(, , , );

     button1.backgroundColor = [UIColor cyanColor];

     [button1 addTarget:self action:@selector(onclick1:) forControlEvents:UIControlEventTouchUpInside];

     [self.view addSubview:button1];

     UIButton * button2 = [UIButton buttonWithType:UIButtonTypeCustom];

     button2.frame = CGRectMake( , , , );

     button2.backgroundColor = [UIColor redColor];

     [button2 addTarget:self action:@selector(onclick2:) forControlEvents:UIControlEventTouchUpInside];

     [self.view addSubview:button2];

 }

 -(void)onclick1:(UIButton *)btn{

     UIActionSheet * actionsheet = [[UIActionSheet alloc]initWithTitle:@"提示信息" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确认" otherButtonTitles:nil];

     [actionsheet showInView:self.view];

 }

 -(void)onclick2:(UIButton *)btn{

     UIAlertView * alterView = [[UIAlertView alloc]initWithTitle:@"警告" message:@"您的言论违法中华人民共和国法律,有可能查你水表" delegate:self cancelButtonTitle:@"继续发表" otherButtonTitles:nil];

     [alterView show];

 }
