A couple possibilities: You did not link UIImage+TTShare.m into your target. So while you have the header, you’re not compiling the implementation. If this is part of a static library, you need to add -all_load to the Other Linker Flags build setting for the app linking against the library.
Maven has since been updated and can use categories. An example from the Surefire documentation: <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.11</version> <configuration> <groups>com.mycompany.SlowTests</groups> </configuration> </plugin> This will run any class with the annotation @Category(com.mycompany.SlowTests.class)
If it is a category page,you can get id of current category by: $category = get_category( get_query_var( ‘cat’ ) ); $cat_id = $category->cat_ID; If you want to get category id of any particular category on any page, try using : $category_id = get_cat_ID(‘Category Name’);
From Apple documentation: Although the Objective-C language currently allows you to use a category to override methods the class inherits, or even methods declared in the class interface, you are strongly discouraged from doing so. A category is not a substitute for a subclass. There are several significant shortcomings to using a category to override … Read more
Sometimes, you just have to use a for-loop: for col in [‘parks’, ‘playgrounds’, ‘sports’, ‘roading’]: public[col] = public[col].astype(‘category’)
Yes, that’s possible. The syntax is: @interface NSDate (CategoryName) <ProtocolName> @end @implementation NSDate (CategoryName) @end Here’s Apple’s documentation on the topic. It’s also possible to do this using a class extension. I very much like this to privately conform to delegate protocols. Doing so hides the implementation detail of being some delegate of some class … Read more
.h-file @interface NSObject (LaserUnicorn) @property (nonatomic, strong) LaserUnicorn *laserUnicorn; @end .m-file #import <objc/runtime.h> static void * LaserUnicornPropertyKey = &LaserUnicornPropertyKey; @implementation NSObject (LaserUnicorn) – (LaserUnicorn *)laserUnicorn { return objc_getAssociatedObject(self, LaserUnicornPropertyKey); } – (void)setLaserUnicorn:(LaserUnicorn *)unicorn { objc_setAssociatedObject(self, LaserUnicornPropertyKey, unicorn, OBJC_ASSOCIATION_RETAIN_NONATOMIC); } @end Just like a normal property – accessible with dot-notation NSObject *myObject = [NSObject new]; myObject.laserUnicorn … Read more
Solution: As of Xcode 4.2, you only need to go to the application that is linking against the library (not the library itself) and click the project in the Project Navigator, click your app’s target, then build settings, then search for “Other Linker Flags”, click the + button, and add ‘-ObjC’. ‘-all_load’ and ‘-force_load’ are … Read more
Another option would be to disable the warning with: #pragma GCC diagnostic ignored “-Wundeclared-selector” You can place this line in the .m file where the warning occurs. Update: It works also with LLVM like this: #pragma clang diagnostic push #pragma clang diagnostic ignored “-Wundeclared-selector” … your code here … #pragma clang diagnostic pop
They didn’t forget. They just moved it without telling anyone. Click File -> New -> File Select Objective-C file under Sources in iOS or Mac OS respectively and Click Next Now under File Type: choose either Category, Protocol, or Extension PS. Under File Name: whatever you type here will be either the Category, Protocol, or … Read more
