? ? ? ?UI總結(jié)-tableView的界面?zhèn)髦?br>
因為tableView在以后的開發(fā)占了很重要的地位,所以把tableView的界面?zhèn)髦祮为毮贸鰜碜隽诉@一篇,里面涉及了tableView界面之間的屬性,協(xié)議傳值和tableView的刷新等功能.
ViewController.m文件:

//實現(xiàn)協(xié)議方法
-(void)sendValue:(NSString *)str{
//把傳過來的人名加到屬性數(shù)組里
[self.arr addObject:str];
UITableView *table = (UITableView *)[self.view viewWithTag:1000];
//刷新tableView
[table reloadData];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

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

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

}
//tableView的點擊方法
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

SecondViewController *vc = [[SecondViewController alloc]init];
[self.navigationController pushViewController:vc animated:YES];

[vc release];
//簽協(xié)議
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];
//協(xié)議傳值
[self.delegate sendValue:@"水滸傳"];
}
運行的效果:
