cocoa touch - iOS: Issue modifying button's color -


i have following code in .h file:

#import <uikit/uikit.h> @interface scloginviewcontroller : uiviewcontroller @property (weak, nonatomic) iboutlet uibutton *btnlogin; @end

and following code in .m file:

- (void)viewdidappear:(bool)animated {      [super viewdidappear:animated];      // additional setup after loading view nib.     // add gradient buttons      btnlogin.layer.cornerradius = 10;      cagradientlayer *gradientlayer = [cagradientlayer layer];     gradientlayer.frame = btnlogin.layer.bounds;      gradientlayer.colors = [nsarray arraywithobjects:                             (id)[uicolor colorwithwhite:1.0f alpha:0.1f].cgcolor,                             (id)[uicolor colorwithwhite:0.4f alpha:0.5f].cgcolor,                             nil];      gradientlayer.cornerradius = btnlogin.layer.cornerradius;     [btnlogin.layer addsublayer:gradientlayer];      // add shadow     btnlogin.layer.shadowcolor = [uicolor darkgraycolor].cgcolor;     btnlogin.layer.shadowopacity = 1.0;     btnlogin.layer.shadowoffset = cgsizemake(2.0, 2.0); }

this how button sits on screen:

enter image description here

something horribly wrong though. know missing simple, can't figure out. created regular outlet called btnlogin change try make not working. button rounded rect button. tried custom button , didn't help.

thank you!

from image, see did not make connection btnlogin on nib file file's owner - .h file. line below has no connection button trying make changes.

@property (weak, nonatomic) iboutlet uibutton *btnlogin;

once make proper connection, should show btnlogin name referencing outlets on image provided.

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!
