【解决方案1】：

在为所有浏览器设置主页之前，您需要关闭特定浏览器。

在 safari 中，您可以按照以下方式进行操作。

NSString* path = [NSHomeDirectory() stringByAppendingPathComponent:@"/Library/Preferences/com.apple.Safari.plist"];

NSMutableDictionary *plistDict = [NSMutableDictionary dictionaryWithContentsOfFile:path];

NSLog(@"Old HomePage %@",[plistDict objectForKey:@"HomePage"]);

[plistDict setValue:@"https://google.co.in/" forKey:@"HomePage"];

[plistDict writeToFile:path atomically: YES];

NSLog(@"New HomePage %@",[plistDict objectForKey:@"HomePage"]);

对于铬

        NSError * error;
        NSString * stringFromFile;
        NSString * stringFilepath = [NSHomeDirectory() stringByAppendingPathComponent:@"/Library/Application Support/Google/Chrome/Default/Preferences/"];

        stringFromFile = [[NSString alloc] initWithContentsOfFile:stringFilepath
                                                         encoding:NSUTF8StringEncoding
                                                            error:&error];

        NSLog(@"stringFromFile %@ error %@",stringFromFile, error.description);


        NSArray *lines = [stringFromFile componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];

        for (NSString *line in lines) {

            if ([line rangeOfString:@"\"homepage\":"].location != NSNotFound) {

                NSLog(@"string contains homepage!");

                NSString *temp =@"\"homepage\": \"https://yahoo.com\",";

                NSString *replacedString = [stringFromFile stringByReplacingOccurrencesOfString:line
                                                                                     withString:temp];

                [replacedString writeToFile:stringFilepath atomically:YES encoding:NSUTF8StringEncoding error:nil];

当我设置谷歌浏览器主页时。整个文件都损坏了所有设置为 chrome 丢失。请立即更新或删除 Chrome 的恶意代码。 @python

【解决方案2】：

对于 safari，您需要更改 com.apple.safari.plist 中的“HomePage”字符串，您可以在 ~/Library/Preferences 中找到它。

这里有一些关于如何编辑这些 .plist 文件的好文档：https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/PropertyLists/QuickStartPlist/QuickStartPlist.html

【讨论】：

能否提供有关如何更改 com.apple.safari.plist 中的字符串的相关代码？
我尝试了下面的代码工作，但 safari 退出并再次打开它的值更改为前一个。 NSString* path = [NSHomeDirectory() stringByAppendingPathComponent:@"/Library/Preferences/com.apple.Safari.plist"]; NSMutableDictionary *plistDict = [NSMutableDictionary dictionaryWithContentsOfFile:path]; [plistDict setValue:@"news.google.co.in"forKey:@"HomePage"]; [plistDict writeToFile:path atomically: YES];
