UI总结-tableView的界面传值

因为tableView在以后的开发占了很重要的地位,所以把tableView的界面传值单独拿出来做了这一篇,里面涉及了tableView界面之间的属性,协议传值和tableView的刷新等功能.

ViewController.m文件:

#import "ViewController.h"

#import "SecondViewController.h"

@interface ViewController ()

@property(nonatomic,retain)NSArray *arr1;

@property(nonatomic, retain)NSMutableArray *arr;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

self.view.backgroundColor = [UIColor whiteColor];

//定义数组,里面存数据

self.arr = [NSMutableArray arrayWithObjects:@"宋江", @"卢俊义", @"吴用", @"公孙胜", @"关胜", @"林冲", @"秦明" ,@"呼延灼" , @"花荣",@"柴进", @"李应", @"朱仝",@"鲁智深",@"武松", @"徐宁", @"张清", @"杨志", @"董平", @"索超", @"戴宗", @"刘唐", @"李逵", @"史进", @"穆弘", @"雷横", @"李俊",nil];

UITableView *tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height) style:UITableViewStylePlain];

[self.view addSubview:tableView];

[tableView release];

tableView.dataSource = self;

tableView.delegate = self;

self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(click:)]autorelease];

tableView.tag = 1000;

[self creatData];

}

-(void)creatData{

//在本地找名为stu.plist的文件

NSString *path = [[NSBundle mainBundle]pathForResource:@"stu" ofType:@"plist"];

NSDictionary *dic = [NSDictionary dictionaryWithContentsOfFile:path];

//将本地的数据显示在页面上

self.title = [dic valueForKey:@"name"];

}

//rightBarButtonItem的点击方法

-(void)click:(UIBarButtonItem *)button{

SecondViewController *vc = [[SecondViewController alloc]init];

[self.navigationController pushViewController:vc animated:YES];

[vc release];

}

//实现协议方法

-(void)sendValue:(NSString *)str{

//把传过来的人名加到属性数组里

[self.arr addObject:str];

UITableView *table = (UITableView *)[self.view viewWithTag:1000];

//刷新tableView

[table reloadData];

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return self.arr.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

static NSString *reuse = @"reuse";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuse];

if (!cell) {

cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuse]autorelease];

}

cell.textLabel.text = self.arr [indexPath.row];

return cell;

}

//tableView的点击方法

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

NSLog(@"%@",self.arr[indexPath.row]);

SecondViewController *vc = [[SecondViewController alloc]init];

[self.navigationController pushViewController:vc animated:YES];

vc.str = self.arr[indexPath.row];

[vc release];

//签协议

vc.delegate = self;

}

secondController.h文件:

@protocol SecondViewControllerDelegate

- (void)sendValue:(NSString *)str;

@end

@interface SecondViewController : UIViewController@property(nonatomic, copy)NSString *str;

@property(nonatomic,assign)iddelegate;

@end

secondController.m文件:

#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view.

self.title = self.str;

self.view.backgroundColor = [UIColor grayColor];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

button.frame = CGRectMake(100, 100, 150, 150);

[button setTitle:@"返回" forState:UIControlStateNormal];

[button addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];

button.backgroundColor = [UIColor redColor];

[self.view addSubview:button];

button.layer.borderWidth = 1;

button.layer.cornerRadius = 5;

}

-(void)back:(UIButton *)button{

[self.navigationController popToRootViewControllerAnimated:YES];

//协议传值

[self.delegate sendValue:@"水浒传"];

}

运行的效果:
