IOS -- page Jump (UITableView), ios -- uitableview

In this article, you only need to use a (UITableView) table to implement page value transfer, and use a proxy (delegate) to pass the value.

The directory file list is as follows:

AddressBookViewController. h

#import <UIKit/UIKit.h>#import "ContentViewController.h"@interface AddressBookViewController : UIViewController<UITableViewDelegate,UITableViewDataSource,postValueDelegate>@end

 

AddressBookViewController. m

 

# Import "AddressBookViewController. h "@ interface AddressBookViewController () @ property (strong, nonatomic) UITableView * adderbookview; @ property (strong, nonatomic) NSMutableArray * person; @ property (strong, nonatomic) NSString * str; // define a global variable to receive the number of rows @ property (assign, nonatomic) int number; @ end @ implementation AddressBookViewController-(void) viewDidLoad {// set the navigation bar name self. view. backgroundColor = [UIColor colorWithRed: 0.344 green: 0.976 blue: 1.000 alpha: 1.000]; self. title = @ "Address Book"; // set UIBarButtonItem * nextItem = [[UIBarButtonItem alloc] initWithTitle: @ "next" style: UIBarButtonItemStylePlain target: self action: @ selector (nextPage)]; self. navigationItem. rightBarButtonItem = nextItem; self. person = [NSMutableArray array]; for (int I = 1; I <15; I ++) {[self. person addObject: [NSString stringWithFormat: @ "% d contacts", I];} // initialize the specified style self. adderbookview = [[UITableView alloc] initWithFrame: self. view. frame style: 1]; // specifies the proxy self. adderbookview. delegate = self; self. adderbookview. dataSource = self; [self. view addSubview: self. adderbookview]; [self. adderbookview registerClass: [UITableViewCell class] forCellReuseIdentifier: @ "cell"]; self. adderbookview. separatorColor = [UIColor colorWithRed: 1.000 green: 0.739 blue: 0.353 alpha: 1.000] ;}# pragma mark-Method for redirecting to the next page-(void) nextPage {ContentViewController * contentV = [[ContentViewController alloc] init]; contentV. str = self. str; [self. navigationController pushViewController: contentV animated: YES];} # The pragma mark-proxy method displays the cell information of the selected row-(void) tableView :( UITableView *) tableView didSelectRowAtIndexPath :( NSIndexPath *) indexPath {NSLog (@ "% @", self. person [indexPath. row]); self. str = self. person [indexPath. row]; ContentViewController * contentV = [[ContentViewController alloc] init]; contentV. str = self. str; contentV. delegate = self; self. number = (int) indexPath. row; [self. navigationController pushViewController: contentV animated: YES];} # pragma mark-set to display the number of partitions-(NSInteger) numberOfSectionsInTableView :( UITableView *) tableView {return 1 ;} # pragma mark-function settings for each partition of the data source-(NSInteger) tableView :( UITableView *) tableView numberOfRowsInSection :( NSInteger) section {return self. person. count ;}# pragma mark-content of each cell of the data source-(UITableViewCell *) tableView :( UITableView *) tableView cellForRowAtIndexPath :( NSIndexPath *) indexPath {static NSString * cellIdentity = @ "cell "; UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: cellIdentity forIndexPath: indexPath]; cell. textLabel. text = self. person [indexPath. row]; return cell ;}# pragma mark-Method for proxy-(void) postValue :( NSString *) str {[self. person replaceObjectAtIndex: self. number withObject: str]; [self. adderbookview reloadData];}-(void) didReceiveMemoryWarning {[super didreceivemorywarning]; // Dispose of any resources that can be recreated .} @ end

Note:

1. Click the value of UITableView on the first page;

2. on the second page, you must press the return key on the keyboard to transfer the value to the first page.
