iOS simple Get view screenshot image (quartz2d)

1. Specify the size of the image first

Uigraphicsbeginimagecontext (view.frame.size);

2. Drawing an image in the specified area

[View DrawViewHierarchyInRect:view.bounds Afterscreenupdates:no];

3. Get the image context

UIImage *image = Uigraphicsgetimagefromcurrentimagecontext ();

4. Close the image context

Uigraphicsendimagecontext ();

That's right! It takes only 4 lines of code to get an image of the specified view.

In addition, the common drawing image has another method:

[View.layer Renderincontext:uigraphicsgetcurrentcontext ()];

Let me add a method Example:

+ (UIImage *) Getimageviewwithview: (UIView *) view{    uigraphicsbeginimagecontext (view.frame.size);    [View DrawViewHierarchyInRect:view.bounds Afterscreenupdates:no];     *image = uigraphicsgetimagefromcurrentimagecontext ();    Uigraphicsendimagecontext ();         return image;}
