ios – Xcode错误：“_ main”,引用自：主要可执行文件的隐式入口/启动

我收到以下错误,这似乎来自底层的事情与“_main”.

任何帮助将非常感激.

解决方法

我检查了你的项目.问题很简单,在你的项目中没有main.m文件.我想你不小心删了那个.

将新的.m文件添加到项目中,将其命名为main

并添加以下代码：

#import <UIKit/UIKit.h>
#import "AppDelegate.h"

int main(int argc,char * argv[]) {
    @autoreleasepool {
        return UIApplicationMain(argc,argv,nil,NSStringFromClass([AppDelegate class]));
    }
}

同样在您的项目中,info.plist也缺失,因此您需要添加一个新的.
