Question

采用X代码4.3.2,把故事板作为新版,因此,密码知识并不很好。我迄今为止是由主要观点控制器创建的,这些控制器与我载有数据的表象相链接。然而,我知道如何将这个内容与一个新的观点控制员联系起来,即如果把新的观点控制员拖到故事板上,那么我就希望能够选择桌面调查中的小组,然后打开一个包含细节的新页。至今,在辅导员的帮助下,我的法典是:

View Controller.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITabBarDelegate, UITableViewDataSource, UISearchBarDelegate>
    {
    IBOutlet UITableView * tableView;
    IBOutlet UISearchBar * searchBar;

        NSArray * allItems;
        NSMutableArray * displayItems;
}

@end

View Controller.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    allItems = [[NSArray alloc] initWithObjects:@"K12", @"K14", @"K16", @"K18", @"K42", @"K43", @"K46", @"K53", @"K60", @"K68", @"K81", @"K83", nil];
    displayItems = [[NSMutableArray alloc] initWithArray:allItems];

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return  1;    
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [displayItems count];
}

- (UITableViewCell *)tableView:(UITableView *)atableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
    }
    cell.textLabel.text = [displayItems objectAtIndex:indexPath.row];
    return cell;
}

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
    if ([searchText length] == 0) {
        [displayItems removeAllObjects];
        [displayItems addObjectsFromArray:allItems];
    } else {
        //here
        [displayItems removeAllObjects];
        for (NSString * string in allItems) {
            NSRange r = [string rangeOfString:searchText options:NSCaseInsensitiveSearch];
            if (r.location != NSNotFound) {
                [displayItems addObject:string];
        }
    }
}

    [tableView reloadData];
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)aSearchBar {
    [searchBar resignFirstResponder];
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

@end

我感到宽慰的是,在座右边的那部分人看着各种法典,但因为我的知识非常有限,我只需要一张珍贵的指南,或者说如果有人能够告诉我什么法典来补充,那将是巨大的。

Thanks Guys and help would be appreciated.

Okay, I will assume that you will use the same nib to display the information, regardless of which row is selected. First, right-click or ctrl-click on your "Views" folder, and select "New File". Create a new UIViewController class, with .xib. My view controller will have a label (for the name of the car), a UIImageView (of the car, populated by an image that has the same name as the car, with a .jpg appendix), and a textView populated by a dictionary. The textView will display information about the car, and I have pre-loaded the dictionary with that information, keyed to the name of the car, like so:

[dictionary setObject:@"This is a car." forKey:@"Ford Taurus"];

字典是单一州,因此每一类别都可以查阅(见https://stackoverflow.com/a/10093449/542400)。如何执行。现在,我有我的新的观点,即“新老会”和综合体(我的第一个看法是,主计长可以查阅),我将确保我的第一种看法,即选举一行时,主计长将作出回应:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    NewVC *new = [[NewVC alloc] init];
    //assuming you have no array from which you populated your table
    new.myString = [[[myTable cellForRowAtIndexPath:indexPath] textLabel] text];

    //assuming you have a navigationController
    [self.navigationController pushViewController:new animated:YES]; 
}

现在,在我的“新千禧年”项目中,我采用了以下方法:

-(void)viewWillAppear:(BOOL)animated{
    [myLabel setText:myString];
    NSString *string = [NSString stringWithFormat:@"%@.jpg", myString];
    UIImage *image = [UIImage imageNamed:string];
    [myImageView setImage:image];
    //see above for sharedDictionary info
    [myTextView setText: [[MainDictionary sharedDictionary]getStringForKey:myString]];
    [super viewWillAppear:YES];
}

这是一个非常基本的执行情况,但我希望它将使这一进程明确无误。通过为字典钥匙和图像名称制定简单的命名公约,你的工作将更加容易。
