小编Jim*_*y_m的帖子

我试图忽略UITapGestureRecognizer在UITableView上点击以下内容:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
      if ([touch.view isKindOfClass:[UITableViewCellContentView class]]) {
          return NO; // ignore the touch
      }
      return YES; // handle the touch
}

它不会编译:"使用未声明的标识符'UITableViewCellContentView'

没有文档的课程？需要子类？更好的方法来完成这个？

谢谢你的帮助.

链接错误:

ld: duplicate symbol _OBJC_METACLASS_$_Reachability in /Users/jmf/Documents/iOS Development/jmf_Client/jmf/jmf/ww_libs/libmfcbroem_ios.a(Reachability.o) and /Users/tpf/Library/Developer/Xcode/DerivedData/jmf-erlknghfcpoomnfanzovahfacgpv/Build/Intermediates/jmf.build/Debug-iphoneos/jmf.build/Objects-normal/armv7/Reachability.o for architecture armv7

如果我只是删除h/m文件(和相关的导入指令),希望只使用libmfcbroem_ios.a中的Reachability ...链接器会抛出:

Undefined symbols for architecture armv7:
  "_kReachabilityChangedNotification", referenced from:
      -[MKNetworkEngine initWithHostName:customHeaderFields:] in MKNetworkEngine.o
      -[MKNetworkEngine dealloc] in MKNetworkEngine.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如何告诉链接器使用"a"文件中的Reachability？

(免责声明,我刚刚开始使用ObjC/iOS)

谢谢你的帮助...

好的,我已经读了好几个小时了.数十个SO帖子和博客等.没有找到答案.

目标:从我的WCF服务启用json响应的动态http压缩.

注意:当applicationhost.config包含以下内容时,gzip已经适用于静态内容和动态内容:

<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
            <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
        <dynamicTypes>
            <add mimeType="text/*" enabled="true" />
            <add mimeType="message/*" enabled="true" />
            <add mimeType="application/x-javascript" enabled="true" />
            <add mimeType="application/json; charset=utf-8" enabled="true" />
            <add mimeType="*/*" enabled="false" />
        </dynamicTypes>
        <staticTypes>
            <add mimeType="text/*" enabled="true" />
            <add mimeType="message/*" enabled="true" />
            <add mimeType="application/x-javascript" enabled="true" />
            <add mimeType="application/atom+xml" enabled="true" />
            <add mimeType="application/xaml+xml" enabled="true" />
            <add mimeType="*/*" enabled="false" />
        </staticTypes>    
</httpCompression>
</system.webServer>

不幸的是在服务器上我使用applicationhost.config中缺少以下行:

<add mimeType="application/json; charset=utf-8" enabled="true" />

而且我无法手动添加它,因为服务器是由Elastic Beanstalk启动的AWS EC2实例(因此我可以在一个实例上更改它,但在启动时不在所有实例上更改它).

还不幸的是,applicationhost.config包含以下行:

<section name="httpCompression" allowDefinition="AppHostOnly" overrideModeDefault="Deny" />

这意味着我无法覆盖应用程序的web.config中的httpCompression部分.

我的问题:我是否应该尝试其他方法来启用动态内容的gzip压缩？ …

我正在尝试使用Json序列化objc对象以将其发送到服务器.

同一服务器在GET上为此对象类型发送以下内容:

 {
   "TypeProperties":[
      {"Key":"prop 0","Value":"blah 0"},
      {"Key":"prop 1","Value":"blah 1"},
      {"Key":"prop 2","Value":"blah 2"},
      {"Key":"prop 3","Value":"blah 3"}
     ],
   "ImageURls":[
      {"Key":"url 0","Value":"blah 0"},
      {"Key":"url 1","Value":"blah 1"},
      {"Key":"url 2","Value":"blah 2"},
      {"Key":"url 3","Value":"blah 3"}
     ]
}

SBJsonWriter为我在objc中创建的匹配对象/类型生成以下内容:

{
  "TypeProperties": {
    "key 2": "object 2",
    "key 1": "object 1",
    "key 4": "object 4",
    "key 0": "object 0",
    "key 3": "object 3"
  },
  "ImageUrls": {
    "key 0": "url 0",
    "key 1": "url 1",
    "key 2": "url 2"
  }
}

这就是我使用SBJsonWriter的方式:

SBJsonWriter *writer = [[SBJsonWriter alloc] init]; …

谁能告诉我如何解决这个异常？调试器位于异常断点处,正如您所看到的,似乎没有关于异常的可操作信息.它发生在哪里？很确定它不在我的代码中,但我不知道如何继续......

非常感谢任何帮助.
