objective c 截屏代码

objective c 截屏代码

-(void)save{
   
    UIGraphicsBeginImageContext(mybackgroundview.bounds.size);     //currentView 当前的view
    [mybackgroundview.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

}截取 您想要的一层
UIGraphicsBeginImageContext(CGSizeMake(320, 300));     //currentView 当前的view
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);
截取自定义的大小
刚刚用到  不知道 是不是您想要的
