iphone - Transform resets(redraws) all my former moved views -


i'm moving around image views timers , animation blocks. @ same time user can click on few of these views(buttons) , have more animation blocks start moving/resizing/rotating different image views.

changing alpha of views , giving out new cgpoint views works me calling resizing or rotating uiview.transform function seems reset views starting position(from storyboard).

i love able use transform function inside animation block if can't somehow bypass reset not viable option me.

example code:

- (void)movegust:(nstimer*) timer {     if(centercloud1.x >= 1100)     {         centercloud1.x = -79;         gustoutlet.center = centercloud1;     }     if(centercloud2.x >= 1100)     {         centercloud2.x = -79;         cloudoutlet.center = centercloud2;     }      centercloud1 = gustoutlet.center;     centercloud1.x = round(centercloud1.x+10);     centercloud2 = cloudoutlet.center;     centercloud2.x = round(centercloud2.x+8);      [uiview animatewithduration:2 delay:0 options:uiviewanimationoptionallowuserinteraction | uiviewanimationoptioncurvelinear animations:^(void){         gustoutlet.center = centercloud1;         cloudoutlet.center = centercloud2;     }completion:^(bool finished){ }]; }  - (ibaction)signaction:(id)sender {      [uiview animatewithduration:0 animations:^(void) {         signtop.transform = cgaffinetransformscale(signtop.transform, 1.1, 1.1);     }]; }

any ideas? thanks!

successive transforms need concatenated using cgaffinetransformconcat().

when set view's transform equal new transform, "undo" previous transforms. series of transforms, concatenate them above method.

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!
