iOS 10 截屏保存到相册

截屏保存到相册

UIGraphicsBeginImageContextWithOptions(CGSizeMake(self.bounds.size.width, self.bounds.size.height), YES, 3);
[[self layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *imag = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

CGImageRef ima =imag.CGImage;
UIImage *sendImag = [UIImage imageWithCGImage:ima];
UIImageWriteToSavedPhotosAlbum(sendImag, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

保存相册回调 可以做相应的动画化提示
-(void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{

if (error == nil) {
    NSLog(@"保存成功");
}else{
    NSLog(@"保存失败");
}

}
iOS10 需要配置infoPlist
