objective c - Strikethrough Text with Animation iOS -


what best way display strikethrough animation? when user swipes finger across uitableviewcell, animate thin line across cell.textlabel.text

the 2 ways i've thought of far using animation or somehow displaying custom image , revealing left right? have advice on this?

i have swipe gestures working, need know how make animation happen:

add gesture recognizer:

  //add left swipe gesture recognizer     uiswipegesturerecognizer *recognizer = [[uiswipegesturerecognizer alloc] initwithtarget:self                                                                                      action:@selector(handleswipeleft:)];     [recognizer setdirection:(uiswipegesturerecognizerdirectionleft)];     [self.tableview addgesturerecognizer:recognizer];      //add right swipe gesture recognizer     recognizer = [[uiswipegesturerecognizer alloc] initwithtarget:self                                                            action:@selector(handleswiperight:)];     recognizer.delegate = self;     [recognizer setdirection:(uiswipegesturerecognizerdirectionright)];     [self.tableview addgesturerecognizer:recognizer];

delegate methods gestures:

- (void)handleswipeleft:(uiswipegesturerecognizer *)gesturerecognizer {      nslog(@"uncompleted"); }  // cross item off of list - (void)handleswiperight:(uiswipegesturerecognizer *)gesturerecognizer {     nslog(@"completed"); }

based on have far following should work:

  1. when handleswipeleft (or right) fires, place new uiview black background color on textfield @ textfield's x point , around halfway y point width of 0 , height of 1
  2. then, call [uiview animationwithduration....] changing uiview's width property width of textfield.

this should close want tweaking. don't think possible animate strikethrough using properties of font alone technique should simulate fine.

good job on getting half way there.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
