UIActionSheet
[objc] view plaincopy
- #import "FirstViewController.h"
- @interface FirstViewController ()<UIActionSheetDelegate,UIAlertViewDelegate>
- @property (retain, nonatomic) IBOutlet UILabel *aLabel;
- @property (retain, nonatomic) IBOutlet UITextField *textField;
- @end
- @implementation FirstViewController
- - (void)viewDidLoad {
- [super viewDidLoad];
- // Do any additional setup after loading the view from its nib.
- }
- - (IBAction)upButton:(UIButton *)sender {
- //UIActionSheet
- UIActionSheet *sheet = [[UIActionSheet alloc]initWithTitle:@"选择" delegate:self cancelButtonTitle:@"取消按钮" destructiveButtonTitle:@"确认按钮" otherButtonTitles:nil, nil nil];
- sheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
- // 更改标题
- sheet.title = @"请点击您的选择";
- // 添加按钮
- //添加的按钮位置从第三个算起
- [sheet addButtonWithTitle:@"添加的按钮"];
- //红色按钮位置
- sheet.destructiveButtonIndex = 0;
- [sheet showInView:self.view];
- [sheet release];
- //UIAlertView
- //一般来说,根据苹果官方制定的《iOS 用户界面指南》,在拥有两个按钮的对话框中,您应当将取消按钮放在左边
- UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"是否已满十八岁?" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil nil];
- alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
- //UIAlertViewStyleDefault 默认风格,无输入框
- //UIAlertViewStyleSecureTextInput 带一个密码输入框
- //UIAlertViewStylePlainTextInput 带一个文本输入框
- //UIAlertViewStyleLoginAndPasswordInput 带一个文本输入框,一个密码输入框
- [alert show];
- [alert release];
- }
第一种 ActionSheet单独使用
[objc] view plaincopy
- //第一种 ActionSheet单独使用
- //接收ActionSheet点击事件
- //该方式由UIActionSheetDelegate协议定义,点击ActionSheet的按钮后自动执行
- - (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
- switch (buttonIndex) {
- case 0:
- self.aLabel.text = self.textField.text;
- break;
- case 1:
- break;
- case 2:
- NSLog(@"让你点你还真点");
- break;
- default:
- break;
- }
- }
第二种,单独使用UIAlertView
[objc] view plaincopy
- //接收UIAlertView点击事件
- -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
- {
- switch (buttonIndex) {
- case 0:
- break;
- case 1:
- self.aLabel.text = self.textField.text;
- break;
- default:
- break;
- }
- }
第三种混合使用
[objc] view plaincopy
- - (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
- NSString *string=[NSString stringWithFormat:@"你选择了 %@",[actionSheet buttonTitleAtIndex:buttonIndex]];
- UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"输入账户和密码" message:string delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil nil];
- alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
- //UIAlertViewStyleDefault 默认风格,无输入框
- //UIAlertViewStyleSecureTextInput 带一个密码输入框
- //UIAlertViewStylePlainTextInput 带一个文本输入框
- //UIAlertViewStyleLoginAndPasswordInput 带一个文本输入框,一个密码输入框
- switch (buttonIndex) {
- case 0:
- [alert show];
- break;
- case 1:
- break;
- default:
- break;
- }
- [alert release];
- }
[objc] view plaincopy
- - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
- {
- //该方法由UIAlertViewDelegate协议定义,在点击AlertView按钮时自动执行,所以如果这里再用alertView来弹出提示,就会死循环,不停的弹AlertView
- // NSString * string=[NSString stringWithFormat:@"你点击了 %@",[alertView buttonTitleAtIndex:buttonIndex]];
- NSString * string=[NSString stringWithFormat:@"你点击了 %@",[alertView buttonTitleAtIndex:buttonIndex]];
- switch (buttonIndex) {
- case 0:
- break;
- case 1:
- self.aLabel.text = self.textField.text;
- break;
- default:
- break;
- }
- // UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"提示" message:string delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
- // [alert show];
- NSLog(@"%@",string);
- // NSLog(@"输入 %@",[[alertView textFieldAtIndex:0] text]);
- //获取第一个文本框输入的文本,如果没有文件框,会异常,索引从0开始
- }
- [objc] view plaincopy
- <span style="background-color: rgb(255, 0, 0);"><span style="color:#99ff99;">最终效果:</span></span>
