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.
