objective c - UBER iOS SDK - 401 error -

i following uber ios sdk documentation integrate uber app.

https://github.com/uber/rides-ios-sdk

i trying integrate "ride request button" app , copy pasted example code documentation

ubsdkriderequestbutton *button = [[ubsdkriderequestbutton alloc] init]; [self view] addsubview:button]; ubsdkridesclient *ridesclient = [[ubsdkridesclient alloc] init]; cllocation *pickuplocation = [[cllocation alloc] initwithlatitude: 37.787654 longitude: -122.402760]; cllocation *dropofflocation = [[cllocation alloc] initwithlatitude: 37.775200 longitude: -122.417587]; __block ubsdkrideparametersbuilder *builder = [[ubsdkrideparametersbuilder alloc] init]; builder = [builder setpickuplocation: pickuplocation]; builder = [builder setdropofflocation: dropofflocation]; [ridesclient fetchcheapestproductwithpickuplocation: pickuplocation completion:^(ubsdkuberproduct* _nullable product, ubsdkresponse* _nullable response) {     if (product) {         builder = [builder setproductid: product.productid];         button.rideparameters = [builder build];         [button loadrideinformation];     } }]; 

the block ubsdkresponse (response.response) looks below

<nshttpurlresponse: 0x15c6c1eb0> { url: https://sandbox-api.uber.com/v1/products?latitude=37.787654&longitude=-122.40276 } { status code: 401, headers {     connection = "keep-alive";     "content-length" = 63;     "content-type" = "application/json";     date = "thu, 01 sep 2016 21:39:12 gmt";     server = nginx;     "strict-transport-security" = "max-age=0";     "x-content-type-options" = nosniff;     "x-uber-app" = "uberex-sandbox, migrator-uberex-sandbox-optimus";     "x-xss-protection" = "1; mode=block"; } } 

i have configured uberclient id in app in info.plist file. not sure missing 401 response.

thanks

you need add server token info.plist.

copy snippet info.plist (right click , select open > source code) , replace [your server token] server token dashboard (make sure use server token corresponding client id).

<key>uberservertoken</key> <string>[your server token]</string> 

hope helps!
