小编Bab*_*oot的帖子

我有一个UIWebView,我想让它成为transperent,因为我在Imageview中有背景图像.我试过webView.backgroundColor = [UIColor clearColor];但它没用.

谢谢

在我的项目中,我必须将a的长度限制UITextField为6个字符.这工作绝对正常.一旦我结束编辑并再次开始编辑,我点击退格我的应用程序崩溃.

这是代码:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string 
{   
    NSUInteger newLength = [txtLicense.text length] + [strNumber length] - range.length;
    return (newLength > 6) ? NO : YES;
}

是否可以仅延迟返回值,而不是像整个方法一样:

-(CGFloat)getValue
{
    // code implementation
    return floatvalue; // return float value with some delay.
}

默认文本的颜色是什么UIButton？我正在尝试在一些表视图单元格中重新创建它但没有运气.我最接近的是:

[UIColor colorWithRed:0/255.0 green:51.0/255.0 blue:102.0/255.0 alpha:1];

是否在任何地方记录了颜色,字体大小和样式？

我通过解析"fmt stream map"来获取Stream URL,

问题是如果我的视频持续时间不到1小时,我会得到这个:

{
"comment_count" = 1;
description = "";
"dislikes_num" = 0;
duration = "54:46";
"encrypted_id" = WWjNEyHrNsk;
"fmt_stream_map" =     (
            {
        "fallback_host" = "tc.v7.cache6.c.youtube.com";
        itag = 22;
        quality = hd720;

我已经下载了common.codec二进制jar文件.现在我想使用这个类org.apache.commons.codec.binary.Base64.但这个文件夹包含四个jar文件,即common.codec-1.7.jar,commons-codec-1.7-javadoc.jar,commons-codec-1.7-sources,commons-codec-1.7-tests,commons-codec-1a.7-test-sources.现在我应该在课程路径中提到哪条路径？我尝试使用所有jar文件路径并在我的程序中导入但失败了.请告诉我在哪里放置这个下载的jar文件以及如何在我的代码中使用它.

首先我想知道,当我点击本地通知时,会调用哪种特定方法.我想点击通知打开一个网址.下面是代码应用程序委托.现在的问题是,即使我没有点击通知,网址也会自动打开.如果你知道的话请指导我.谢谢

 - (void)application:(UIApplication *)application didReceiveLocalNotification:      (UILocalNotification *)notifyAlarm
    {
        application.applicationIconBadgeNumber = 0;
        NSLog(@"Notification tapped :) ");
       [[UIApplication sharedApplication] openURL:[NSURL          URLWithString:@"http://www.google.com.pk"]]; }

我有一个NSString对象,它是一个包含长随机字符组的网页的URL.我想提取字符串中只有两个斜杠之间的字符.任何人都可以帮我这样做吗？例如,我想在以下字符串中提取somewebpage.com和nextlink之间的刺痛.

链接.

我使用的是OSX 10.7.5,XCode 4.5,RevMob v 5.5.1.

当我点击左上角的播放按钮时,XCode会生成以下错误:

Undefined symbols for architecture armv7:
  "_SCNetworkReachabilityGetFlags", referenced from:
      -[BCFAdsReachability connectionRequired] in RevMobAds(BCFAdsReachability.o)
      -[BCFAdsReachability currentReachabilityStatus] in RevMobAds(BCFAdsReachability.o)

截图:

这是编译源和链接库列表,以防有人向我推荐一些旧线程:

我想我已经正确地链接了所有二进制文件.但是,我确实使用了模拟器和我的iPhone来试用该应用程序,但它仍然显示上述错误.

你能否告诉我缺少什么以及应该采取什么措施来解决这个问题？

谢谢.

当我在wso2 esb中使用call out mediator时,使用DSS Endpoint我只收到请求,我没有得到响应,即使我把登录按顺序排列.我在这里发送我的代理服务.

例如-1:我有像"aaa-23-34"这样的字符串,我希望字符串是"aaa-23"

例如-2: var str = "aaa-44-34-12"

输出应该是 "aaa-44-34"

这意味着我想在最后一个连字符之前使用字符串.

我使用wcf服务直接处理数据库。

我得到的结果是这种格式： DIA_User[]

我可以使用 linq 作为选择、查找、...但我不知道如何转换为 List<DIA_User>

请指教。

非常感谢。

假设我有如下数据:

A = [{'X1': val1, 'X2': 'val2', 'X3': 'val3', 'X4': val4}]

如何提取val1,val2,val3,val4？

什么是最快的方式？
