我想获得我已加载到iOS项目中的所有本机类(NSString,NSNumber,int,float,NSSet,NSDictionary).
即,如果我创建了一个名为“TestClass”的自定义类,我不希望它列出…
我已经有了一个代码,但它返回了所有类的名称,我可以修改代码将列表限制为仅限于本机类吗？
- #import <objc/runtime.h>
- #import <dlfcn.h>
- #import <mach-o/ldsyms.h>
- unsigned int count;
- const char **classes;
- Dl_info info;
- dladdr(&_mh_execute_header,&info);
- classes = objc_copyClassNamesForImage(info.dli_fname,&count);
- for (int i = 0; i < count; i++) {
- NSLog(@"Class name: %s",classes[i]);
- Class class = NSClassFromString ([NSString stringWithCString:classes[i] encoding:NSUTF8StringEncoding]);
- // Do something with class
- }
解决方法
你会得到所有加载的类
- int numClasses;
- Class * classes = NULL;
- classes = NULL;
- numClasses = objc_getClassList(NULL,0);
- if (numClasses > 0 )
- {
- classes = (__unsafe_unretained Class *)malloc(sizeof(Class) * numClasses);
- numClasses = objc_getClassList(classes,numClasses);
- for (int i = 0; i < numClasses; i++) {
- Class c = classes[i];
- NSLog(@"%s",class_getName(c));
- }
- free(classes);
- }
(来自objc_getClassList文档的代码.)
要限制列表,您可以检查从中加载类的包,例如
- Class c = classes[i];
- NSBundle *b = [NSBundle bundleForClass:c];
- if (b != [NSBundle mainBundle])
- ...
对于未从您的应用程序加载的所有类.
