ios - PDF in UIWebView not working -


i have 2 uipopovercontroller. each 1 opens pdf in uiwebviewdelegate when click respective buttons. however,only 1 works. both buttons, , b, have format click function (except button b buttonb not buttona)

- (ibaction)openpdf_pictures_a:(id)sender {       buttonapdfviewcontroller *dwv =[[buttonapdfviewcontroller alloc] initwithnibname:nil bundle:nil];      self.masterpopovercontroller = [[uipopovercontroller alloc] initwithcontentviewcontroller:dwv];      [self.masterpopovercontroller presentpopoverfromrect:[sender frame] inview:[sender superview] permittedarrowdirections:uipopoverarrowdirectionany animated:yes];     [self.masterpopovercontroller setpopovercontentsize:cgsizemake(600, 800) animated:no];     }

and in uiviewcontroller each uiwebview, this:

#import "buttonaviewcontroller.h"  @interface buttonaviewcontroller ()  @end  @implementation buttonaviewcontroller  @synthesize buttonapdfview;  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // custom initialization     }     return self; }  - (void)viewdidload {     [super viewdidload];       nsstring *path = [[nsbundle mainbundle] pathforresource:@"parta" oftype:@"pdf"];     nsurl *targeturl = [nsurl fileurlwithpath:path];     nsurlrequest *request = [nsurlrequest requestwithurl:targeturl];     [buttonapdfview loadrequest:request];    } - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  @end

both buttons , b on same view. did make 1 of ibactions use masterpopovercontroller2 , 1 of masterpopovercontroller see if resolve doesn't. 1 doesn't work opens popover doesn't show pdf in popover. suggestions?

just realized didn't add uiwebview inside uiview in xib...
