小编use*_*827的帖子

我正在尝试根据我在TableView中选择的行将数据发送到我的DetailViewController.我的项目是用StoryBoard制作的.

我的TableViewCell与我的MainStoryBoard中的UIView链接得很好,一切都很好,我不知道如何将所选行的信息发送到我的DetailView

这是我有的:

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

{
    NSUInteger section = [indexPath section];
    NSUInteger row = [indexPath row];
    NSUInteger oldRow = [lastIndexPath row];
    NSString *key = [keys objectAtIndex:section];
    detailRow = [names objectForKey:key];
    static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];
    if (cell == nil)
    {
        CGRect cellFrame = C

GRectMake(0, 0, 300, 65);
        cell = [[UITableViewCell alloc] initWithFrame:cellFrame] ;
    }
    CGRect nameLabelRect = CGRectMake(200, 5, 200, 15);
    UILabel *nameLabel = [[UILabel alloc] initWithFrame:nameLabelRect];
    nameLabel.tag = kNameValueTag; …

我想得到一个字符串的值.值在NSDictionnary中,但NSDIctionnary在NSArray中.

我怎样才能获得价值？例如,我想获得关键字"路径"的字符串

谢谢你的帮助.

<array>
    <dict>
        <key>path</key>
        <string>2.mov</string>
        <key>width</key>
        <string>768</string>
        <key>height</key>
        <string>1024</string>
    </dict>
</array>

我想将NSArray添加到我的NSMutable(appdelegate中的init)

这是我的代码,每次按下按钮(男性,女性,情侣)时都会调用该方法,因此必须将NSArray添加到MutableArray中,但我不知道我尝试过但不起作用.:

     - (void) sexChoosen:(NSString *) sexe
{
    NSError *err;
    NSFetchRequest *request = [[NSFetchRequest alloc] init];
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Boxes" inManagedObjectContext:context];
    [request setEntity:entity];

    NSArray *arrayForPredicate = [context executeFetchRequest:request error:&err];
    NSPredicate *sex;

    sex = [NSPredicate predicateWithFormat:@"sexe = %@", sexe];

    NSArray  *BoxWithSex = [arrayForPredicate filteredArrayUsingPredicate:sex];
    //NSMutableArray* tmp = [self createMutableArray:BoxWithSex];

    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    NSLog(@"FIRST  %@", appDelegate.myArray);

// HERE IS THE CODE TO ADD THE ARRAY TO MY NSMUTABLE ARRAY = AppDelegate *appDelegate

    NSLog(@"SECOND %@", appDelegate.myArray);

}
