I have an error at compile time. Seems to be weird. it worked as
detail view application but using single view doesn't seem to work.

this is the error details

Programming Languages

I am a beginner in native application.I am developing applications
using Objective C as front end , SUP as middleware and SAP as
backend.I have a valid provisioning certificate with a valid bundle
identifier.I tried deploying one of my simple applications into the
device(iPAD) which is not having any connection to the backend,and
only having some basic navigations from one screen to another.And it
has been successfully deployed.


But my problem is when I
am deploying my application which is having connection to the
middleware and using SUP libraries,it is showing build failed 'Linker
command failed with Exit code 1'.I think it is because of the use of
Libraries from SUP

Web Development

For a slow-loading VC, I decided to delete all the excess code that
was commented out. Before doing this I copied all the code from the
class into TextEdit and saved it to my desktop. Then I began cutting
out extraneous code but because there was a mixture of // and /*
*/
in the course of cutting it out I accidentally deleted a
closing brace causing the entire remainder of the code to turn
green.



Because I couldn't immediately figure out what I had cut correctly
and whether I cut too much, I decided to copy the entire contents from
the backed up textEdit file and replace the original code in the
class--or so I thought. However, since doing that the App will no
longer run as it gives the following error:

This is new to me and I can't figure out what to do. The name of
the file that I copied from textEdit was SettingsVC. There is also
another file in the project called IDSettings that does something
different, however, I did not do anything to that.



There are no red image files in the navigator pane. However, the
xctest file is in red although I've read this is not unusual.



Would appreciate any advice on how to fix this problem.
