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(100, 100, 100, 50);
    button1.backgroundColor = [UIColor cyanColor];
    [button1 addTarget:self action:@selector(onclick1:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button1];
    
    UIButton * button2 = [UIButton buttonWithType:UIButtonTypeCustom];
    button2.frame = CGRectMake(100 , 200, 100, 50);
    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];
}
