One week of iOS development

Summary 1: Regarding a screenshot of the uploaded project, it is best to keep the screenshots of 3.5 and 4.0 consistent. If your application requires an account, then the test account you provided to Apple when uploading the application must have data that you want to associate with all of your servers, otherwise there is a possibility of rejection. The reason is simple, the screenshot you provided Apple thinks you are fake because your data does not match the screenshot.
Summary 2: If your old project is still created under 5.0, when you use some libraries, you find that there is no problem with the sdk of 7. 0 and Apple is upward compatible, then you may suspect that your library is too old, in fact Otherwise, because the 5.0 foundation library has a new library called coreText, you must include it, otherwise the compiler will give you an error, which roughly means that the path of frame armv7s cannot be found. Check the targets path search paths Libary found no problems. Then you need to do it like this.
Summary 3: Encountering a problem probably means that scrollivew loads some images because it needs to bring a preview function. So when you go from A to B interface, it is found that sometimes the picture will have problems. If there is no problem with the print data, then you need to check. The scrollview is not cleared at home first, indicating that a problem is not only to be careful to do a project, but also to know the principle.
Summary 4: Project compilation problem. If your project is non-ARC and needs to compile ARC third-party library, then you need to add -fobjic-arc. 
 If your ARC library xu needs to compile non-ARC library then You need to add 
-fno-objc-arc  
and then how do you release the other original.
