1.记得开启访问相机权限，否则会崩溃
//截全屏
- (UIImage *) captureScreen {
UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
CGRect rect = [keyWindow bounds];
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[keyWindow.layer renderInContext:context];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return img;
}
// 保存 - (void)saveScreenshotToPhotosAlbum:(UIView *)view
{
UIImageWriteToSavedPhotosAlbum(@"你想保存的图片" nil, nil, nil);
}回调方法 - (void)image: (UIImage *) image didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo
{
NSString *msg = nil ;
if(error != NULL){
msg = @"保存图片失败" ;
NSLog(@"保存失败");
}else{
msg = @"保存图片成功" ;
NSLog(@"保存成功");
}
}
