The reference to a third-party framework does not support ARC, and the third-party arc
We often encounter a problem when referencing a third-party framework and discovering that it does not support Automatic Memory Processing (ARC)
We need to do this:
Enter-fno-objc-arc in the text box;
Now our third-party files can be used, and there may be some minor errors. I encountered it When referencing jsonkit, but the system will automatically prompt and modify it;
How does allegro draw an Arc border? I drew it using 3pt Arc + Line, prompting that the border is not closed and cannot be operated on.
For example, set the parameters, set the Options Value, set the Options Value Based on the arc size requirement, click the side to be skewed, click another side, and right-click Done.
What is cross-browser encapsulation of third-party frameworks?
Because the mainstream three browsers (FF, IE, and Opera) have many differences in html dom processing and Javascript objects, this brings a lot of trouble to WEB developers (it is a typical case that the same WEB page is different in different browsers), and Javascript is particularly troublesome in this regard, therefore, common WEB developers will keep up with three browsers and continuously test compatibility.
The so-called cross-browser encapsulation of third-party frameworks means that they have completed the encapsulation of the differences among these mainstream browsers. When you call the same method, it selects the most appropriate operations for different browsers, so that you do not need to consider the details of the browser too much.
