二、UISearchBar和UISearchDisplayController（实时搜索）
#import "MainViewController.h"

}

@end

}

//table
UITableView *table = [[UITableView

320, self.view.frame.size.height-64)

table.dataSource =
self;
table.delegate =
self;
[self.view
addSubview:table];
[table release];
table.tag = 6666;
table.tableHeaderView = searchBar;//一般都把搜索框放到一个table的头上
//display(展示搜索出来的东西用的table，也是个table)
_display = [[UISearchDisplayController
alloc] initWithSearchBar:searchBar
contentsController:self];//第一个参数是哪儿搜我有反应，第二个参数是我显示在哪个VC
_display.searchResultsDataSource =
self;
_display.searchResultsDelegate =
self;
}
#pragma markTable代理
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
//因为display也是一个table那样的控件，所以他也会走table的代理方法
//所以要在table的代理方法中判断，是我们的table还是display的table

三、自定义实时搜索
#import "MainViewController.h"
@interface

BOOL _isEdit;//判断是否在输入，也就是判断是否正在查找，用来设置table的数据源是dataArr还是resultArr；
}
@property(nonatomic,retain)NSMutableArray *dataArr;

@end

}
-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super
initWithNibName:nibNameOrNil
bundle:nibBundleOrNil];
if(self)
{
self.dataArr = [NSMutableArray
arrayWithCapacity:0];
self.resultArr = [NSMutableArray

_isEdit =

}
return
self;
}
- (void)viewDidLoad {

self.automaticallyAdjustsScrollViewInsets =
NO;
[self loadData];

}
-(void)loadData

}
}
-(void)makeUI
{
//1、table
UITableView *table = [[UITableView
alloc] initWithFrame:CGRectMake(0,
104,
320, self.view.frame.size.height-104)
style:UITableViewStylePlain];
table.dataSource =
self;
table.delegate =
self;
[self.view
addSubview:table];
[table release];
table.tag = 6666;
//2、搜索框
UITextField *text = [[UITextField
alloc] initWithFrame:CGRectMake(10,
69, 300,
30)];
text.borderStyle =
UITextBorderStyleRoundedRect;
text.delegate =
self;
[self.view
addSubview:text];
[text release];
text.tag = 5555;
[text addTarget:self
action:@selector(textEditChange:)

}
#pragma mark textField的代理
-(void)textFieldDidBeginEditing:(UITextField *)textField

//所有UIView的子类都可以用这个动画,UIView动画

animateWithDuration:2
animations:^{
//想写啥写啥
textField.frame =

69, 240, 30);
}];
//textField.frame = CGRectMake(10, 69, 240, 30);
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField

[UIView
animateWithDuration:2
animations:^{

69, 300, 30);
}];
[textField resignFirstResponder];
return
YES;
}
//随时关注textField的内容改变
-(void)textEditChange:(UITextField*)text
{//从数据源里查找有没有我们输入的textfield的内容，这个方法因为每多写一个字就调用一次，所以就是实时查找了
//1、清空上次查找结果
[self.resultArr

//2、查找

in self.dataArr)//遍历数据源查找
{
//text.text就是输入框里的文字

}
}
//3、刷新table
UITableView *table = (UITableView*)[self.view

#pragma mark table的代理
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

else

return cell;
}
四、索引（就是屏幕右边一竖行的字母）
#import "MainViewController.h"
@interface
MainViewController ()<UITableViewDataSource,UITableViewDelegate>
@property(nonatomic,retain)NSMutableArray *dataArr;
@end
@implementation MainViewController
-(void)dealloc

}
return

}
- (void)viewDidLoad {
[super viewDidLoad];
self.automaticallyAdjustsScrollViewInsets =
NO;
[self loadData];
[self makeUI];
}
-(void)loadData
{
//有段有行的data数据源,索引引导的就是段
for(int i =

{
NSMutableArray *arr = [NSMutableArray

for(int j =
0;j<9;j++)

}

addObject:arr];
}
NSLog(@"%@",self.dataArr);
}
-(void)makeUI
{
UITableView *table = [[UITableView
alloc] initWithFrame:CGRectMake(0,
64,
320, self.view.frame.size.height-64)
style:UITableViewStylePlain];
table.dataSource =
self;
table.delegate =
self;
[self.view
addSubview:table];
[table release];
}
#pragma mark table代理
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{//行

}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{//瓤
static NSString *iden =

if(cell == nil)
{

alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:iden] autorelease];
}
cell.textLabel.text =
self.dataArr[indexPath.section][indexPath.row];
return cell;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{//段
return
self.dataArr.count;
}
-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [NSString

}
//设置table的索引,索引内容应该和段头一样

}
#pragma markTable代理

三、自定义实时搜索
#import "MainViewController.h"
@interface

}

}
-(void)makeUI

//1、table
UITableView *table = [[UITableView

320, self.view.frame.size.height-104)
style:UITableViewStylePlain];
table.dataSource =
self;
table.delegate =
self;
[self.view
addSubview:table];

table.tag = 6666;
//2、搜索框

#pragma mark textField的代理

四、索引（就是屏幕右边一竖行的字母）
#import "MainViewController.h"
@interface

@property(nonatomic,retain)NSMutableArray *dataArr;
@end
@implementation MainViewController
-(void)dealloc

}
return
self;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.automaticallyAdjustsScrollViewInsets =
NO;
[self loadData];
[self makeUI];
}
-(void)loadData
{
//有段有行的data数据源,索引引导的就是段
for(int i =
'A';i<= 'Z';i++)
{
NSMutableArray *arr = [NSMutableArray
arrayWithCapacity:0];//这个数组给小循环用
for(int j =
0;j<9;j++)
{
[arr addObject:[NSString
stringWithFormat:@"%c%d",i,j]];
}
[self.dataArr
addObject:arr];
}
NSLog(@"%@",self.dataArr);
}
-(void)makeUI
{
UITableView *table = [[UITableView
alloc] initWithFrame:CGRectMake(0,
64,
320, self.view.frame.size.height-64)
style:UITableViewStylePlain];
table.dataSource =
self;
table.delegate =
self;
[self.view
addSubview:table];
[table release];
}
#pragma mark table代理
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{//行
return [self.dataArr[section]
count];
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{//瓤
static NSString *iden =
@"pp";
UITableViewCell *cell = [tableView

if(cell == nil)
{

}
cell.textLabel.text =
self.dataArr[indexPath.section][indexPath.row];
return cell;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{//段
return
self.dataArr.count;
}
-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [NSString
stringWithFormat:@"%C",section+'A'];
}
//设置table的索引,索引内容应该和段头一样
-(NSArray*)sectionIndexTitlesForTableView:(UITableView *)tableView
{

for(int i =
'A';i<='Z';i++)

}
return arr;
}
-(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
NSLog(@"%@",title);
NSLog(@"%ld",(long)index);
return index;
}
