以上图片是Gmail应用程序的示例。
我想要的是,
图片2 - 我想显示这样的建议列表,当用户点击该建议时,必须根据该搜索值导航下一个视图
图片3 A - (在打字之前)当我点击搜索栏按钮时,就像我要显示的这个视图一样,我也希望显示图像中显示的分段控件。
图片3 B - 当用户根据搜索值开始输入时,必须在表格视图上显示数据。
我不太详细了解表格视图及其功能。我想了解如何在iOS中实现此功能。
任何人都可以帮助我实现此功能。

步骤1 :只需创建一个搜索导航按钮
UIButton *searchButton = [UIButton buttonWithType:UIButtonTypeCustom];
[searchButton setImage:[UIImage imageNamed:@"search1"] forState:UIControlStateNormal];
[searchButton addTarget:self action:@selector(searchButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[searchButton setFrame:CGRectMake(10, 0, 35, 35)];
UIView *rightBarButtonItems = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 76, 32)];
[rightBarButtonItems addSubview:searchButton];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarButtonItems];
第2步:在对其执行操作后,编写用于导航下一个视图的代码
- (IBAction)searchButtonClicked {
SearchViewController * search=[self.storyboard instantiateViewControllerWithIdentifier:@"SearchViewControllerId"];
[self.navigationController pushViewController:search animated:YES];
}
第3步:获取一个文本字段和分段控件(如屏幕截图所示),并在分段控件下方添加2个表格视图并编写代码。
// This method used to allow select segmented button multiple times (multi-select segmented control)
-(void)setMultiSelectControl:(MultiSelectSegmentedControl *)multiSelectControl{
_multiSelectControl = multiSelectControl;
self.multiSelectControl.tag = 2;
self.multiSelectControl.delegate = self;
}
-(void)multiSelect:(MultiSelectSegmentedControl *)multiSelecSegmendedControl didChangeValue:(BOOL)value atIndex:(NSUInteger)index{
if(index==0)
{
_multiSelectControl.selectedSegmentIndex=0;
_tableview1.hidden=NO;
_tableview2.hidden=YES;
[_seachTextField resignFirstResponder];
// your code
}
if (index==1) {
_multiSelectControl.selectedSegmentIndex=1;
_tableview1.hidden=YES;
_tableview2.hidden=NO;
[_seachTextField resignFirstResponder];
// your code
}
}

第1步:只需创建搜索
的导航按钮即可 UIButton *searchButton = [UIButton buttonWithType:UIButtonTypeCustom];
[searchButton setImage:[UIImage imageNamed:@"search1"] forState:UIControlStateNormal];
[searchButton addTarget:self action:@selector(searchButtonClicked) forControlEvents:UIControlEventTouchUpInside];
[searchButton setFrame:CGRectMake(10, 0, 35, 35)];
UIView *rightBarButtonItems = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 76, 32)];
[rightBarButtonItems addSubview:searchButton];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarButtonItems];
第2步:在对其进行操作后,编写用于导航下一个视图的代码
- (IBAction)searchButtonClicked {
SearchViewController * search=[self.storyboard instantiateViewControllerWithIdentifier:@"SearchViewControllerId"];
[self.navigationController pushViewController:search animated:YES];
}
第3步:获取一个文本字段和分段控件,如下面的屏幕截图所示,并在分段控件下面添加2个表视图并编写代码。
// This method used to allow select segmented button multiple times (multi-select segmented control)
-(void)setMultiSelectControl:(MultiSelectSegmentedControl *)multiSelectControl{
_multiSelectControl = multiSelectControl;
self.multiSelectControl.tag = 2;
self.multiSelectControl.delegate = self;
}
-(void)multiSelect:(MultiSelectSegmentedControl *)multiSelecSegmendedControl didChangeValue:(BOOL)value atIndex:(NSUInteger)index{
if(index==0)
{
_multiSelectControl.selectedSegmentIndex=0;
_tableview1.hidden=NO;
_tableview2.hidden=YES;
[_seachTextField resignFirstResponder];
// your code
}
if (index==1) {
_multiSelectControl.selectedSegmentIndex=1;
_tableview1.hidden=YES;
_tableview2.hidden=NO;
[_seachTextField resignFirstResponder];
// your code
}
}
我希望这会对你有所帮助。
