After Xcode5, the new iOS project, the default is the arc mode, but sometimes we need to use some third-party framework in the project, we download and found that is non-arc, this time we need to do arc and MRC mixed.

The arc and arcto functions are the arc-drawing functions under MFC, which are actually formed by intercepting a part from an elliptic. Bool Arcto ( Lpcrect Lprect , Point Ptstart , Point Ptend );Here, lprect is the rectangular area to which the arc belongs. The elliptic is generated based on this rectangle. Ptstart and ptend are used to specify the

In SVG spec 1.2 and earlier versions, there is only one way to draw an elliptical arc, that is, an arc is determined by starting point, ending point, long half axis, short half axis, large and small Arc Mark, clockwise marking, and inclination. This method is powerful and flexible, and can draw any elliptical arc. Some

Objective-c is a simple, powerful and flexible programming language with both object-oriented features and functional programming features. Because it is a C-language vest, that is, objective-c can convert its source code into a pure C language and then compiled into the final target code, so we can also use it to write pure C language code, it is fully compatible with C! (This is different from the C + + features that are compatible with the syntax features)Because there are many objective-c en

UnderstandingXcode 4.2Automatic Reference CountingARC) Is the content to be explained in this article, Automatic Reference Counting (ARC), Automatic reference counting, is a compilation-level feature when developing a Cocoa program, used for automatic memory management. InXCode 4.2.ARCFeatures. If your iOS SDK is iOS5 seed release 2, you need to make the following changes to avoid compilation errors: In System/Library/Frameworks/CoreFoundation.

ARC and MRC in the iOS-ten "faces" ambush-interview magic booksI have been in touch with iOS for some time. From the first time I was a newbie who could only write NSLog, to a simple page layout that could use the basic control layout, I learned how to write core animations, every step is very pleased. I encountered various problems and various inexplicable "crashes" on the way. Fortunately, I was never frustrated. On the contrary, I was very active i

ARC is the automatic reference calculation. English name automatic Reference counting.In the beginning of iOS development, memory management is the need to manually, a reference to a resource, the reference to its calculation +1, when no longer used on-1, when the calculation of 0, there is no object reference to this resource, it can be freed. Later, people feel that this is not possible, what should be done automatically to do these things, of cours

When you start learning iOS development, it's best not to turn on arc, which can help you learn memory management, but many friends who have just contacted Xcode may find that when you use the latest version of Xcode, you'll be prompted with an error when typing in code such as release. This is because the system uses automatic memory management by default, and below is a brief explanation of how to set up this arc.Note: After IOS 5.0, after xcode4.2A

__strong of Arc mechanism__strong parsing :By default, a pointer uses the __strong property to indicate that this is a strong reference. This means that the object cannot be destroyed as long as the reference exists. This is the desired behavior: when all (strong) references are removed, the object can be collected and freed.However, there are times when we want to disable this behavior: Some collection classes should not increase the references to t

Summary : New knowledge is added to ios5, that is, arc. In fact, I don't like it very much because I am used to managing the memory myself. However, learning is still necessary. During iOS development, the attribute definition is often related to retain, assign, and copy. I think everyone is familiar with it. I will not introduce it here. ...
