1.創建一個ViewController,New File->Cocoa Touch->Objective-C class->Class:ViewController,Subclass of:UIViewController
2.打開xib,在view中添加TableView,並將TableView的兩個屬性拖到File's Owner中,
可以設置tableview的分區樣式,選擇style
3.ViewController.h:
#import <UIKit/UIKit.h>
@interface newViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
@property (retain, nonatomic) IBOutlet UITableView *tableView;
@property(retain,nonatomic)NSDictionary *dic;
@property(retain,nonatomic)NSArray *keys;
@end
4.ViewController.m:
#import "newViewController.h"
@interface newViewController ()
@end
@implementation newViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"sortednames" ofType:@"plist"];
self.dic = [NSDictionary dictionaryWithContentsOfFile:path];
self.keys = [self.dic allKeys];
self.keys = [self.keys sortedArrayUsingSelector:@selector(compare:)];
}
//tableView有多少分區
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.keys count];
}
//每個分區對應多少行
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSString *key = self.keys[section];//通過第幾個分區拿到對應的key
NSArray *arr = [self.dic objectForKey:key];//通過這個key獲得對應的Array
return [arr count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *str = @"str";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:str];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:str];
}
int section = [indexPath section];
int row = [indexPath row];
NSString *key = self.keys[section];
NSArray *arr = [self.dic objectForKey:key];
cell.textLabel.text = arr[row];
return cell;
}
//在每個分區上顯示什麼內容
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return self.keys[section];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//設置索引
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
return self.keys;
}
