Question

我正在为学校制作一个项目，我遇到了表视图控制器的问题，我想添加一个按钮将它链接到另一个页面，真的是它，所以我有一个7个表格单元的列表连接到详细信息视图控制器，从那里我想添加一个按钮，将其链接到另一个页面，但7个表格单元格中的每一个都需要转到不同的页面，对不起，我不是很擅长解释事情，但如果任何人可以帮助我真的很感激。

#import "tableViewController.h"
#import "TableCell.h"
#import "DetailViewController.h"

@interface tableViewController ()

@implementation tableViewController

- (id)initWithStyle:(UITableViewStyle)style

self = [super initWithStyle:style];

    // Custom initialization

return self;

[super viewDidLoad];

// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;

// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;

_Review=@[@"Not Reviewed",@"'I'm a big fan of whey protein becasue the dosing is simple, easy to consume, and usually a lot cheaper than pills. I use to use the regular old GNC 100% whey protein which was good to take after a workout, but I really wanted more from my supplements. Proto Whey had a lot of great reviews and I have to say, it worked pretty well for me.'",@"'Wow. This stuff is amazing. No fillers, the taste (lemon-lime) isn't overwhelming, and I can work out solid for 1.5 hours and still feel like a beast. I've taken NO-Xplode and Black Powder, and I find that Jack3d provides more energy, while something like Black Powder gives me more pump. This is why I mix a scoop of Black Powder and a scoop of Jack3d and get totally effed at the gym.I've come to notice that if I take jack3d later in the day, it really messes with my sleep, and I contribute that to the DMAA in it, which is a stimulant. I just finished a bottle and I notice my tolerance was going up. On days that I was taking just jack3d, since I like to mix it up, I moved up to 2 scoops towards the end of the bottle. So all in all, awesome for energy in the gym, only somewhat decent regarding pump. But I still give it a solid 9. I have yet to try out 1.M.R, which I will be getting next week, and can find out then which is better for me.BTW I didn't get a 'crash' that so many people speak of, this could be that maybe I am not just prone to the type of thing, and that I work out after I get off work, so 'crashing' really doesn't matter for me.'",@"Not Reviewed",@"'I had the double chocolate flavor and it was the BEST tasting stuff I've ever had. It was so good, sometimes I just took a serviing for breakfast if I was running short on time. The effectiveness was good too, and after finishing a tub of it, I noticed just about all of my lifts increased. I gained some great vascularity in my bi's, and my chest strength exploded. Honestly, for all of you who want to spend a little money and get a nice supplement...this is your winner. I am definitely gonna use this for a while until I get sick of the taste or see a new up-and-coming product. Only reason I give value a 5 is because I paid about $40 for the 2LB tub back in January.'",@"Not Reviewed",@"Not Reviewed",];

表格cell.m为空，.h用于IBOutlets

Answer 1

在DetailViewController上创建一个公共@property，您可以在prepareForSegue:sender: TableViewController中设置它，以在每个DetailViewController中设置按钮的目标。

// DetailViewController.h
@interface DetailViewController    
@property NSInteger nextPageId;  // or whatever

// TableViewController.m
// prepareForSegue...
detailviewcontroller.nextPageId = myIndexPath.row;  // something like this

// DetailViewController.m
// viewDidLoad...
[myButton addTarget:self action:@selector(myButtonHandlerMethod) forControlEvents:UIControlEventTouchUpInside];

-(void)myButtonHandlerMethod {
   // code to present the next "page" based on self.nextPageId
}

方法addTarget:action:forControlEvents:设置了当用户点按按钮时要调用的另一个方法myButtonHandlerMethod。如果UIButton位于DetailViewController Storyboard中，则创建一个IBOutlet属性并将该按钮引用为self.myButton。
