ios开发莫名其妙的问题解集

一、xcode4 attaching to appname问题解决方法:

please note, this is not a sequence of steps. each one is a possible solution:

1- restart xcode and/or restart simulator (reset content and settings) and/or restart computer.

2- click on project name in project navigator. in build settings tab, go to packaging and make sure that "Product Name" is the same that the one xcode says simulator is attaching to when running. if they are different, it will fail.

3- go to your projectname.xcodeproj folder. inside there delete anything named with your userid. when you reopen xcode those files will be recreated and it should work…

4- Manually delete the build directory for your project.

5- Go to organizer window. select Projects, select your app in the left hand side and then delete over "Derived Data"

6- Check Launch option is set to "Automatically" in Product->Edit Scheme, "Run" scheme.

7- In Project->"Edit Schemes"->Run. Change the Debugger from GDB to None (this doesn't make sense to me..).

8- Kill the process gdb-i386-apple-darwin from Activity Monitor. this is assuming gdb is not responding.

9- In "Product"->Edit Scheme. in Run, click yourappname.app, choose other, navigate to your .app in your project. now run.

10- Check that you don't have two different Info.plist in your project. if you do, remove the bad one.

试到第七步 Change the Debugger,改变成各种状态 问题解决～

 

二、使用GCDAsyncSocket时候（或者其他第三方库）:

发生上述问题可能以及排除：

(1)少包含了framework --->包含相应的framework

(2)点项目->target->build phases -> Complie Source ,看看其中有没有你想要的资源文件.h+.m  ----->添加相应文件到其中就ok了
