I am trying to follow the steps given here:
http://docs.pushmote.com/docs/import-pushmote-ios-sdk-swift
but I am getting this error: 'PushmoteSDK/Headers/Pushmote.h' file not found, when I try and build my app.
Its my Pushmote-Bridging-Header.h file that has this import statement and the file is clearly there, in project_dir/PushmoteSDK.framework/Headers/Pushmote.h
I have read about a few other header file not found error with xcode and the solutions seem to vary a lot, so I think it might have to do with the specific version of xcode. Perhaps someone has used pushmote with xcode7 before and can assist?
EDIT:
This is my Pushmote-Bridging-Header.h file found in /Users/alex/ios_projects/Monkey/Monkey/Pushmote-Bridging-Header.h
#ifndef Pushmote_Bridging_Header_h
#define Pushmote_Bridging_Header_h
#import "PushmoteSDK/Pushmote.h"
#endif /* Pushmote_Bridging_Header_h */
You should change import line like this;
#import "PushmoteSDK/Headers/Pushmote.h"
to
#import "PushmoteSDK/Pushmote.h"

To set up Receipt-Validation in my iOS app, I am now following this tutorial:
https://www.raywenderlich.com/9257-in-app-purchases-receipt-validation-tutorial
and reading at this point: Loading the Receipt.
While reading and attempting to understand what is going on I also try to integrate the code in my own app, by doing so getting a hands-on understanding of the process.
Here is one problem I am hitting at this moment:
On this line of code:
private func loadReceipt() -> UnsafeMutablePointer<PKCS7>? {
I get this error message:
Use of undeclared type 'PKCS7'
After searching the net and trying a few things, I guess it is related to the use of the use of the ReceiptVerifier-Bridging-Header.h file. But I am not sure how to set it in the project.
I will be glad if anyone has some tip allowing me to move forward.
Thanks in advance!
In case this can be useful, here is the meaningful contents of the bridging header file (ReceiptVerifier-Bridging-Header.h):
#import <openssl/pkcs7.h>
#import <openssl/objects.h>
#import <openssl/evp.h>
#import <openssl/ssl.h>
#import <openssl/asn1_locl.h>
The problem is that I had simply copied the bridge-header file, without doing the proper setting as explained here:
https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift
Ok, this is the first time I am trying to integrate chartboost and swift, so I will start from the beginning, maybe I missed something. First I have imported chartboost framework into my project, and then manually created the .h file, which I named BridgingHeader.h I added the needed import statements so that file looks like that now:
#ifndef appname_BridgingHeader_h
#define appname_BridgingHeader_h
#import <Chartboost/Chartboost.h>
#import <Chartboost/CBNewsfeed.h>
#import <CommonCrypto/CommonDigest.h>
#import <AdSupport/AdSupport.h>
#import <UIKit/UIKit.h>
#endif
I tried to build, everything went fine, but I noticed that it does not actually import this file. Hence I went to my project build settings, located Swift Compiler - Code Generation and found Objective-C Bridging Header and named it as appname/BridgingHeader.h . Now I am sure it did find the file and tried to import chartboost files, because I got 56 errors, of which all are in the chartboost files. Erros are such as "function definition is not allowed here" or "expected a type". The last error says that it failed to import bridging header. Anyone knows or has any ideas how to make this work?
Thanks
Ok, I my problem.
1) UIKit import should be done as follows:
#import <UIKit/UIKit.h>
#ifndef appname_BridgingHeader_h
#define appname_BridgingHeader_h
#import <Chartboost/Chartboost.h>
#import <Chartboost/CBNewsfeed.h>
#import <CommonCrypto/CommonDigest.h>
#import <AdSupport/AdSupport.h>
#endif
2) for the path, I should just went to the bridging file, in the file inspector copy the full path and paste it in the Swift Compiler - Code Generation.
In the code bellow it says that there is an error and that 'GLES2/gl2ext.h' File not Found. Does anyone know were to add the file or what the file is. Thanks
Code with error:
#include <GLES2/gl2ext.h>
After upgrading to Xcode 6, I had to make the following change to one my projects:
#import <OpenGLES/ES2/glext.h>
I'm trying to configure cocoalumberjack and when I've added ddLogLevel set to LOG_LEVEL_VERBOSE XCode throws "use of undeclared identifier" error. Why is that? How to avoid?
This question indicates that clearing DerivedData and restarting Xcode solves this kind of error.
However you should not include variables in the pre-compiled header as it will be included in every source file and prefix files are somewhat complicated compared to normal header files.
Better is to have use a Constants.h file which contains:
extern int ddLogLevel;
and #import that into your prefix file.
Then create an Constants.m with:
int ddLogLevel =
#ifdef DEBUG
LOG_LEVEL_VERBOSE;
#else
LOG_LEVEL_ERROR;
#endif
This way there is only one instance of ddLogLevel and it can be easily changed at runtime if necessary.
See this question for hints about prefix file best practices.
What solved it for me was changing #import <CocoaLumberjack/CocoaLumberjack.h> to #import CocoaLumberjack;, when using Xcode 8.0 for an Objective-C project.
Droppy’s post is correct and I recommend doing that, but I would like to address the question directly. There is a flaw in your code that may be resulting in the error.
LOG_LEVEL_VERBOSE is defined in DDLog.h. Your header file only imports DDLog.h if __OBJC__ is defined, but uses LOG_LEVEL_VERBOSE without this condition. Therefore if __OBJC__ is not defined, LOG_LEVEL_VERBOSE will be undefined.
Why would __OBJC__ not be defined? The prefix header is prepended to C, C++, Objective-C and Objective-C++ files. Since __OBJC__ is only defined for the latter two, if there are any C or C++ files in your project then the error will occur.
Knowing this, it is clear the ddLogLevel definition should be inside the #ifdef __OBJC__ check. However, you should do what Droppy said, and also make sure all Objective-C imports go inside the check.
For people who use "CocoaLumberjack 2.X" and still facing same issue after pod update, please try to import "DDLegacyMacros.h".
For prefix file users, try something like this :
#ifdef __OBJC__
...
...
#import <DDTTYLogger.h>
#import <DDLog.h>
#import <DDLegacyMacros.h>
#endif
Hope this helps someone else.
Whenever I try to use the OpenCV Stitcher class in iOS and I include the stitcher-header ( #include ) I end up with a compile error "Expected '{'" in exposure_compensate.hpp. Apparently the line
enum { NO, GAIN, GAIN_BLOCKS };
is causing some sort of error.
I am very new to openCV but using other functions like filter2d() work as expected. How can I resolve this?
Try
#import <opencv2/opencv.hpp>
then
#import <UIKit/UIKit.h>
Update: this answer only highlights the bare minimum fix of the problem, and perhaps the root cause: order of dependencies. Please refer to other answers for better code / setup that you put in your project.
In your project, create a Prefix Header, MyProject.pch, and set it in your project's build settings.
Then within that pch file, do something like this:
#ifdef __cplusplus
# include <opencv2/opencv.hpp>
# include <opencv2/stitching/detail/blenders.hpp>
# include <opencv2/stitching/detail/exposure_compensate.hpp>
#else
# import <Foundation/Foundation.h>
# import <UIKit/UIKit.h>
# import <Availability.h>
#endif
I also ran into this problem. As G. Führ ensure you include the opencv headers first. The easiest way to do this is add:
#ifdef __cplusplus
#include <opencv2/opencv.hpp>
#endif
near the top of the apps "Appname-Prefix.pch" header. This is a precompiled header and makes it easy to guarantee that your opencv header will be included before any of the apple headers.
//
// Prefix header
//
// The contents of this file are implicitly included at the beginning of every source file.
//
#import <Availability.h>
#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif
#ifdef __cplusplus
#include <opencv2/opencv.hpp>
#endif
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#endif
This means you won't accidentally include an apple header before this anywhere else in the app.
I had a similar issue and I solved editing directly the opencv-framework files involved (in your case compensate.hpp) and comment from them the definition of the NO enum case definition. In this case the file was blender.hpp, but compensate.hpp has the same structure
Hope this helps
I solved this issue by importing any Apple headers before those of OpenCV, as mentioned in the beginning of the header:
#if defined(NO)
# warning Detected Apple 'NO' macro definition, it can cause build conflicts. Please, include this header before any Apple headers.
#endif
Hope that helps.
In my case, I create a vertical image stitching app with openCV, error show as screenshot below. It is from exposure_compensate.hpp and blenders.hpp. From the error description, the top file is ../CVWrapper.mm, which is in my project instead of openCV pod project.
As above guys said, there is some conflict issue between C++ and Apple MACRO. And we should put C++ header above Apple header.
First, I try a workaround from internet, which said "replace NO with NO_EXPOSURE_COMPENSATOR = 0". This worked, but it modified openCV source code, I don't want to do that because I will not do version control on Pod files, then if other guys clone my repo/project, they will need to do the same modification on those source code.
Then, I follow the error message in Xcode, I did following changes in my CVWrapper.mm file. After that, those two error disappear.
// Before change
#import "CVWrapper.h"
#import "UIImage+OpenCV.h"
#import "stitching.h"
#import "UIImage+Rotate.h"
// After change
#import "stitching.h"
#import "CVWrapper.h"
#import "UIImage+OpenCV.h"
#import "UIImage+Rotate.h"
