5: for architecture armv7s
以下摘自: /questions//what-is-the-difference-between-arm7-and-arm7s
Yes you are right about armv7s is about the iPhone 5. Here some summary info I found on the web:
ARMv6 ISA (used by the ARM11 core in the iPhone 2G and iPhone 3G)ARMv7 (used by modern ARM cores, iPhone 3GS, iPhone 4 and 4S)ARMv7s (new A6 SoC for iPhone 5).
注:错误含义表示 指定的framework 不支持对 armv7s 的支持, 也就不支持搭载A6处理器的iPhone 5.
如果在编译framework或者静态库的工程中依旧编译时,可能是以下设置导致,设置为NO即可
6: Local declaration of "' hides instance variable
1:私有变量与属性变量同名所致
7:Instance variable '' accessed in class method
1:在静态方法不能使用到类的属性变量,否则就报上面的错误
8:ld: symbol(s) not found for architecture i386
1:里面意思说:"_stroyboard" 这个属性在目标类中 根本就没声明!
那就声明一下咯? 注:XCode4.5 会默认声明了,但是只是针对自定义类,系统类还没有. 所以,小心
9:PerformSelector may cause a leak because its selector is unknown
通过如下代码解决产生的编译器警告
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
[self performSelector:nextView];
#pragma clang diagnostic pop

10:unable to open executable
1:检测同一个静态库或工程中是否有两个或以上的想同类文件存在
2:删除模拟器中的应用,删除DerivedData文件夹 重新启动XCode.
11: Property's synthesized getter follows Cocoa naming convention for returning 'owned' objects
不要在头文件声明变量命名是以new copy开头

1.将Build Settings 中Architectures ――> Valid Architectures的arm64删掉，只留armv7、armv7s
2.同上，将Architectures ――>Architectures改为 $(ARHS_STANDARD)armv7，armv7s
3.把Build Active Architecture Only 改为NO

一，libxml/HTMLparser.h file not find
第一种方法：
点击左边项目的根目录，再点击右边的Build Settings，手工输入文字：&Header search
paths&，然后单击（或双击，点击弹出面板下面的&+&号进行添加）&Header search paths
&右边的空白处，输入：/usr/include/libxml2
第二种方法：
点击左边项目的根目录，再点击右边的Build Settings，手工输入文字：&Header search
paths&，然后单击（或双击，点击弹出面板下面的&+&号进行添加）& Header search paths
&右边的空白处，输入：${SDK_DIR}/usr/include/libxml2
二，总是找不到协议：
第一种方法：没有引入该协议，引入该协议
第二种方法：重复引入该协议，重复引入的地方删除
三，启动画面不显示
1&，图片大小尺寸必须符合规定，把所有的图片导入工程中
2&，进入工程Images.xcassets文件夹，把图片拖入对应的AppIcon,LaungchImage
四，ld: library not found for -lcryptoclang: error: linker command failed with exit code 1 (use -v to see invocation)第一种方法:库crypto没有添加进Link Binary With Libraries,添加进去就OK了第二种方法：库crypto已经添加进Link Binary With Libraries，把crypto删除再重新添加进去就OK了
&五，Unsupported compiler 'pilers.llvmgcc42' selected for architecture 'armv7'& Xcode 5
Change your compiler for C/C++/ObjectiveC Go to Build Settings-&Build OPtions-&compiler for C/C++/ObjectiveC; select Default(Apple LLVM5.0)
升级了xcode之后，支持iOS6和iPhone5，不过Build项目的时候，出现了标题所示错误提示信息。
原因是引用的第三方库导致了这个链接错误。
解决办法有三个，随便哪种都能解决：
1.升级涉及到的.a文件
2.在target的Build Settings里面，将Build Active Architecture Only改成YES&& (I choose this)
3.在target的Build Settings里面，找到Valid Architectures，删除其中的armv7s
所以还是觉得，如果是开源库，直接把源代码包含进项目比较靠谱。
&七，使用第三方插件时，出现contentoffset下移20像素的情况：
解决方案：在使用第三方控件的viewcontroller的viewDidLoad方法中添加下面的代码即可
if ([self respondsToSelector:@selector(setEdgesForExtendedLayout:)]) {&&&&&&& [self setEdgesForExtendedLayout:UIRectEdgeNone];&&& }
八，提交app的时候会有no indentities were available for signing 提示
1.在Xcode的Organizer 中可以看到你上传项目的Indetifier
2，在Provisioning中可以建立的文件和Indetifier保持一致
3，下载你所建立的Provisioning文件，然后双击
4，再在Organizer中上传文件就可以了
5，如果在代码中作了修改，需要重新打包再上传，上传的才会是最新的代码
九，no matching provisioning profiles found
1，到Build Settings里面重新选择进入code signing
2，重新选择profiles
十. mutating method sent to immutable object'从字面上理解：可变的消息发给了不可变的对象。比如NSDictionary类型的对象调用setValue方法.应该把NSDictionary 改成NSMutableDictionary类型。十一.Local declaration of 'content' hides instance variable一般是函数里面定义的变量和class属性变量重名了。很少有和系统变量重名的情况十二.unrecognized selector sent to instance大部分情况下是因为对象被提前release了，在不希望他release的情况下，指针还在，对象已经不在了很多时候，是因为init初始化函数中，对属性赋值没有使用self.foo赋值，而是直接对foo赋值，导致属性对象没有retain(心里以为retain了)，而提前释放。十三.使用ASIHTTPRequest编译不通过原因是一些类库没有加进去。把这些库加进去CFNetwork, SystemConfiguration, MobileCoreServices, and libz.dylib十四.添加在UIView中的UIButton&& 单击不起作用原因是UIbutton的frame超出了UIView的frame范围。事实上UIView并没有设置frame，设置完后( 范围一定要在UIButton之外)，UIButton单击就可以了十五.当使用presentViewController和dismissPresentViewController时，如果报这个错 : while& presentation is in progress
修改方法为[mainView dismissModalViewControllerAnimated:NO];& 将参数Animated改为NO；如果报这个错while a presentation or dismiss is in progress，试试这样&if (![[mainView modalViewController] isBeingDismissed]) {&&&&&&& [mainView dismissModalViewControllerAnimated:NO];&&& }
十六.调用系统相册的时候，非常容易出现内存警告，加入绿色代码就会好点：
&&&&&&& UIImagePickerController * picker = [[UIImagePickerController alloc]init];
&&&&&&& picker.delegate =
&&&&&&& picker.allowsEditing = NO;& //是否可编辑
&&&&&&& picker.videoQuality=UIImagePickerControllerQualityTypeL
&&&&&&& //摄像头
&&&&&&& picker.sourceType = UIImagePickerControllerSourceTypeC
&&&&&&& [self presentModalViewController:picker animated:YES];
&&&&&&& [picker release];
十七.ios开发者都遇见过得错误：EXC_BAD_ACCESS 。这个和第二个比较类似。通常的调试方法就是加入NSZombieEnabled变量，加入方法自行百度。
并且开发过程中使用[[NSNotificationCenterdefaultCenter]
来发布本地消息，这个也经常会出现EXC_BAD_ACCESS错误。这个时候只需要在你的view活着viewControllers的dealloc的方法里面加入
[[NSNotificationCenterdefaultCenter]removeObserver:selfname:@"yourNotification"object:nil];就ok了
十八.遇见一个蛋疼的问题"linker command failed with exit code 1 (use -v to see invocation)" 。
翻遍了找不到原因。然后还有这样的警告duplicate symbol _OBJC_CLASS 。原来是在导入某个类的时候导入.m文件，而不是.h文件
十九:clang failed with exit code 254
检测代码中 是否 有 NSLog 打印了 返回 void 的值.
二十:Verify exit code of build task with internal identifier 'CopyPNGFile 123.png'
一:将出错的png,用PhotoShZ喎?"/kf/ware/vc/" target="_blank"
class="keylink"&vcNbY0MLXqru70ru0ziwgIMjnuftQaG90b1Nob3C08rK7v6osuMS689e6zqpKcGcgytTK1C4g16q7u8qxLMfryrnTwyA6PHN0cm9uZz605rSizqpXZWK78snosbjL+cq508O1xCYjMjY2ODQ7yr08L3N0cm9uZz4mIzI2Njg0O8q916q7u7PJPHN0cm9uZz4gUE5HLTI0PC9zdHJvbmc+1eLR+bXEzbzGrLTz0KGxyL3Pus/KyjwvcD4KPHA+Cjxicj4KPC9wPgo8cD4KPHN0cm9uZz4zOjwvc3Ryb25nPjwvcD4KPHA+CjxpbWcgc3JjPQ=="/uploadfile/421.png"

三十五.duplicate symbol _protobuf_c buffer_simple_append in ...错误解决
&选中工程，target，切换到buildsetting标签，定位到other link flag，
输入： 去除-all_load,即可
三十六.ld: symbol dyld_stub_binding_helper not found, normally in crt1.o/dylib1.o/bundle1.o for architectur
错误：ld: symbol dyld_stub_binding_helper not found, normally in crt1.o/dylib1.o/bundle1.o for architecture i386
原因：不支持低版本的系统如3.0
解决:Deployment Target was 3.0. Changing it to 4.3 fixed it.
三十七.当一个tableViewCell被选中的时候，改变一个button的title,这个button有背景图片，改变title不成功
把该button的selected设为NO
三十八.CUICatalog: Invalid asset name supplied: , or invalid scale factor: 2.000000
这个提示的意思是说你用了这个方法
[UIImage imageNamed:name];但是这个name却是空的，所以就报了这个错了。
解决方法，在项目中搜索[UIImage&imageNamed:,然后打印看看所谓的name是否为空。找到后替换。
三十九.XCode开发遇到的&Could not inspect the application package&解决方案
出现这种情况的原因是：项目里含有 Resources 文件夹。解决方案：
1&在项目里把这个 Resources 文件夹 改为别的名字（不要在项目里改文件夹的名字，这是伪改，要进入工程文件夹再改 Resources 名字），再重新引入这个文件夹
2&按住 option 键 ，点击 Xcode 的product 菜单，选中 Clean Build Folder ，然后确定 clean 就OK了

四十四.iOS9 beta 请求出现App Transport Security has blocked a cleartext HTTP (http://)
错误描述：
App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your&&s Info.plist file.
在iOS9&中，将原http协议改成了https协议，使用 TLS1.2 SSL加密请求数据。
解决方法：
在info.plist 加入key
&key&NSAppTransportSecurity&/key&
&key&NSAllowsArbitraryLoads&/key&
四十五.Could not find Developer Disk Image
真机系统太高，Xcode支持不到这个系统，要有这个系统版本的镜像文件 ，/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport ,会列出支持的设备，然后在网上下载对应的文件
四十六.UICollectionView 会在APP再次打开时下沉64像素
