1，保存图片到点击事件、
- (void) saveImageClick {
PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
if (status == PHAuthorizationStatusDenied) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请到【设置-隐私-照片】打开访问开关" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alert show];
} else if (status == PHAuthorizationStatusRestricted) {
NSLog(@"无法访问相册");
} else {
[MBProgressHUD showProgressToView:nil Text:@"保存中..."];
UIImage *saveImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://img.pconline.com.cn/images/upload/upc/tx/wallpaper/1209/07/c0/13693224_1346985492085.jpg"]]];
[self saveImageToPhotos:saveImage];
}
}
2，保存图片到方法、
- (void)saveImageToPhotos:(UIImage*)savedImage {
UIImageWriteToSavedPhotosAlbum(savedImage, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
3，保存图片到回调提示、
- (void)image: (UIImage *) image didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo {
NSString *msg = nil ;
if(error != NULL){
msg = @"保存图片失败" ;
}else{
msg = @"保存图片成功" ;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"保存图片结果提示" message:msg delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alert show];
