在UILabel Xcode中显示NSLog结果 [英] Display NSLog result in UILabel xcode

问题描述

我有RootCtrl&详细信息Ctrl.在RootCtrl上，我有一个uiTableview.我使用此函数编写选择的结果:

I have RootCtrl & DetailCtrl. On RootCtrl, I have a uiTableview. I use this function to write the result of the choice :

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"%@",cell.textLabel.text);

插入 didSelectRowAtIndexPath .我想将UILabel中的NSLog结果显示到Detailctrl中，以便显示另一个视图.我该怎么办?

into didSelectRowAtIndexPath. I'd like to display the NSLog result in UILabel into Detailctrl, so an another view. How I can do it ?

推荐答案

在 RootViewController 中输入以下代码:

Input the code below in the RootViewController:

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSString*yourStringNameHere = [NSString stringWithFormat:@"%@",cell.textLabel.text];
NSLog(@"%@",yourStringNameHere);//this isn't used in retreiving the info
NSNumber *number = [NSNumber numberWithInt:1];
NSDictionary *yourDictionaryNameHere = [NSDictionary dictionaryWithObjectsAndKeys:
                    yourStringNameHere, @"yourStringNameHereDictionary",nil];

在 DetailViewController 中输入以下代码:

---

Input the code below in the DetailViewController:

在头文件(.h)中放置

In the header file(.h) put

IBOutlet UILabel *yourLabelNameHere; 

在主文件(.m)中使用

In the main file(.m) use

yourLabelNameHere.text= [yourDictionaryNameHere objectForKey:(@"yourStringNameHereDictionary")];

注释:

• 如果您无法访问字典，请输入#import"RootViewController.h"
• 我们使用NSDictionary 将数据存储在iPhone内存中，这使我们可以使用其他类中的数据，否则仅使用#import只能从变量的初始化中接收数据.
• 通过密钥从NSDictionary接收字符串
• 在 DetailViewController.h 中设置一个UILabel，该UILabel输出到一个故事板或xib文件
• 要在过渡开始时加载标签，请将字典接收器放在 ViewDidLoad 或 ViewDidLoad调用的方法(-((void)function))中

• If you can't have access the dictionary put #import "RootViewController.h"
• We use the NSDictionary to store data on the iPhone memory, this allows us to use the data from the other class, otherwise with just using #import you only receive the data from the initialization of the variable.
• Receive a string from the NSDictionary from a key
• Set up a UILabel in the DetailViewController.h that outputs to a storyboard or xib file
• For loading the label at the start of the transition, put the dictionary receiver in ViewDidLoad or a method(-(void)function) called by ViewDidLoad
