小编use*_*304的帖子

嗨,我正在用C#做一个小项目,我需要知道从输入源传来的命令,所以我可以相应地做我的工作..这里是例子......

textBox1.Text = "First line \nSecond line";
richTextBox1.Text = "First line \nSecond line";

Richtextbox显示此输出:

第一行

第二行

文本框显示此输出:

第一行第二行

请告诉我如何在文本或richtextbox中显示新行"\n"或返回"\ r"或类似输入作为字符输出.所以我可以知道换行命令来自输入数据.

例如text或richtext框将显示此输出.

第一行\n第二行

谢谢你提前.

我正在尝试将字符串转换为URL但未获得成功.任何更好的方法,或改进下面的代码.谢谢

NSString *strURL = @"http://domain.com/This Is My, Code for This. app";
NSString *escapedUrlString = [strURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(escapedUrlString);

它显示此日志

http://domain.com/This2s2y ,芙ode
0.000000or2his.20x1.55e800047f4p-1029pp

这是我的实际代码发送和保存数据到mysql

NSString *data = @"This Is My, Code for This. app";
NSString *strURL = [NSString stringWithFormat:@"http://domain.com/connection.php?data=%@", data];   

NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];


NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];  

NSURL *urll = [NSURL URLWithString:strResult];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urll];

[request setHTTPMethod:@"GET"];


NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(@"responseData: %@", responseData);

这没有成功,但是当我使用时

data = …

请帮我..

我想在storyboard中的不同控制器之间传递数据.例如.

第一视图控制器

NSString *firstValue;

firstValue = @"First Number";

现在我想将它发送到结果视图控制器并存储

NSString *resultFromFirstVC;

并在标签中显示.

[label setText: resultFromFirstVC];

所以标签显示:

第一号码

嗨,我是iOS开发的新手.我创建了名为socialClass.h的类

#import <Social/Social.h>
#import <Accounts/Accounts.h>

- (void)facebookSharingStatusCheckCall:(NSString *)url image:(NSString *)img status:(NSString *)text viewCont:(UIViewController *)uiVew;

- (void)facebookForIosSix:(NSString *)url image:(NSString *)img status:(NSString *)text viewCont:(UIViewController *)uiVew;

并在socialClass.m

    - (void)facebookSharingStatusCheckCall:(NSString *)url image:(NSString *)img status:(NSString *)text viewCont:(UIViewController *)uiVew 
{
    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
        NSLog(@"service available");

     [self facebookForIosSix:url image:img status:text viewCont:uiVew];

    } else {
        // facebook for iOS 5 function will be called here
    }
}


-(void)facebookForIosSix:(NSString *)url image:(NSString *)img status:(NSString *)text viewCont:(UIViewController *)uiVew
{


if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

        SLComposeViewController *fbcontroller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    SLComposeViewControllerCompletionHandler myBlock = …
