iOS 获取工程内控制器名称

OC 获取Xcode内所有的控制器类名方法

#import <objc/runtime.h>
#import <dlfcn.h>
#import <mach-o/ldsyms.h>

{
    unsigned int count = 0;
    const char **classes = nil;
    Dl_info info;
    dladdr(&_mh_execute_header, &info);
    NSLog(@"%s", info.dli_fname);
    /*
     info.dli_fame 是工程编译时工程的路径
     objc_copyClassNamesForImage 返回所有类的名称
     */
    classes = objc_copyClassNamesForImage(info.dli_fname, &count);
    for (int index = 0; index < count; ++index) {
        NSString *className = [NSString stringWithCString:classes[index] encoding:NSUTF8StringEncoding];
        if ([className containsString:@"ViewController"]) {
            NSLog(@"className = %@", className);
        }
    }
}

附:class与string之间的互相转换

通过类名获取类

NSString *classStr = @"STImageView";
Class STImageView = NSClassFromString(classStr);
STImageView *imageView = [[STImageView alloc]init];

通过类获取类名字符串

NSString *classStr  = NSStringFromClass([STImageViewclass]);
