对话框和table的使用

1，UICVIewControl的生命周期

-(void)viewWillAppear:(BOOL)animated{ //将要显示
    NSLog(@"viewWillAppear....");
    
}

-(void)viewDidAppear:(BOOL)animated{
    NSLog(@"viewDidAppear..."); 显示完成
}


-(void)viewWillDisappear:(BOOL)animated{
 NSLog(@"viewWillDisappear..."); 将要关闭
}

-(void)viewDidDisappear:(BOOL)animated{
    
    NSLog(@"viewDidDisappear..");关闭完成
}

2，对话框

 

UIAlertView方式创建

 

//    添加警告框
    UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"确定删除" message:@"删除" delegate:self cancelButtonTitle:@"ok" otherButtonTitles:@"no", nil];
    
    UIActivityIndicatorView *act=[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    
    [alert show];
    [alert release];

 

UIalertControl创建对话框

  
    NSString *title = NSLocalizedString(@"A Short Title Is Best", nil);
    NSString *message = NSLocalizedString(@"A message should be a short, complete sentence.", nil);
    NSString *cancelButtonTitle = NSLocalizedString(@"Cancel", nil);
    NSString *otherButtonTitle = NSLocalizedString(@"OK", nil);

    
    UIAlertController *alert=[UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    
    
    //设置Action
    UIAlertAction *actionleft=[UIAlertAction actionWithTitle:cancelButtonTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
        NSLog(@"点击了取消");

    
        
    }];
    
    
    UIAlertAction *actionright=[UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        NSLog(@"点击了确定");
    }];
    
    
    //设置输入框
    
    [alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
        textField.text=@"代号";
        
    }];
    
    [alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
        
        textField.text=@"姓名";
    }];
    
    
    
    //将事件添加到UIAlertController
    [alert addAction:actionleft];
    [alert addAction:actionright];
    
    //
    [self presentViewController:alert animated:1 completion:nil];
    //释放对象
//    [actionleft release];
//    [actionright release];
//    [alert release];

 

创建底部对话框

    //创建对话款
    UIAlertController *alert=[UIAlertController alertControllerWithTitle:@"保存成功" message:@"是否继续" preferredStyle:UIAlertControllerStyleActionSheet];
    //添加按钮
    [alert addAction:[UIAlertAction actionWithTitle:@"停留本页" style:UIAlertActionStyleCancel handler:nil]];
    
    [alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {
       
    }]];
    
    //显示对话款
    [self presentViewController:alert animated:YES completion:nil];
