For a friend who used to develop C # or Java, the function naming method of obj-C may not be used to iOS development for the first time. Especially when you open appdelegate. mCodeActually: -(Bool) Application :( uiapplication *) Application didfinishlaunchingwitexceptions :( nsdictionary *) Launchoptions {//Override point for customization after application launch.ReturnYes ;} I don't know if my friends will feel the same way as me.

Scene:Determine if a class string is inside an objectIt is common to think of using type () immediately to implementAnd alsoAlthough the ideas and methods used are useless, but if we start from the characteristics of Python, we can find a better way: Isinstance (OBJ,STR)Str as the only String class within Python3, we can detect if a string is an instance of STRRight here, thank you.------------------------------------------------------------------Clic

As a result of the basic test, the obj-c still do not know very well, do a step confused (in fact, I think there will be only C related problems-_-#), there are some classes of inheritance, declaration, definition aspect is a problem, because before the C + + to object-oriented have a certain understanding, First look at the information in advance to see objc-c this piece of knowledge.

Recently, several projects that use web services use sudzc to generate the obj-C processing code, which has been used very well and very convenient. Previous projects were non-arc projects. A new project of Arc was established, and sudzc also had the code to generate the arc version, so it was previously used. When debugging this project today, we found that the results returned by Web services are all nil, but the results returned by the request are
