1、添加手势识别：
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(imgTapCliclk:)];
UILongPressGestureRecognizer *longTap = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(imglongTapClick:)];
2、imaglongTapClick：
-(void)imglongTapClick:(UILongPressGestureRecognizer *)gesture
{
if(gesture.state == UIGestureRecognizerStateBegan)
{
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:@"保存图片"
delegate:self
cancelButtonTitle:@"取消"
destructiveButtonTitle:nil
otherButtonTitles:@"保存图片到手机",nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[actionSheet showInView:self];
UIImageView *img = (UIImageView *)[gesture view];
_sentImg = img;
}
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) {
UIImageWriteToSavedPhotosAlbum(_sentImg.image, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
}
}
#pragma mark --- UIActionSheetDelegate---
- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
NSString *message = @"呵呵";
if (!error) {
message = @"成功保存到相册";
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:message delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
[alert show];
}else
{
message = [error description];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:message delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
[alert show];
}
}
