1、添加手势识别：
UITapGestureRecognizer*tap = [[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(imgTapCliclk:)];
UILongPressGestureRecognizer*longTap = [[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(imglongTapClick:)];
2、imaglongTapClick：
-(void)imglongTapClick:(UILongPressGestureRecognizer*)gesture
{
if(gesture.state==UIGestureRecognizerStateBegan)
{
UIActionSheet*actionSheet = [[UIActionSheetalloc]initWithTitle:@"保存图片"delegate:self cancelButtonTitle:@"取消"destructiveButtonTitle:nil otherButtonTitles:@"保存图片到手机",nil];
actionSheet.actionSheetStyle=UIActionSheetStyleBlackOpaque;
[actionSheetshowInView:self];
UIImageView*img = (UIImageView*)[gestureview];
_sentImg= img;
}
}
- (void)actionSheet:(UIActionSheet*)actionSheet didDismissWithButtonIndex: (NSInteger)buttonIndex
{
if(buttonIndex ==0) {
UIImageWriteToSavedPhotosAlbum(_sentImg.image,self,@selector(imageSavedToPhot osAlbum: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 = [[UIAlertViewalloc]initWithTitle:@"提示"message:messagedelegate:selfcancelButtonTitle:@"确定"otherButtonTitles:nil];
[alertshow];
}else
{
message = [errordescription];
UIAlertView*alert = [[UIAlertViewalloc]initWithTitle:@"提 示"message:messagedelegate:selfcancelButtonTitle:@"确定"otherButtonTitles:nil];
[alertshow];
}
}
