我需要使用plist进行数据持久化。如何将视图控制器中的值存储到plist中，然后在表视图中显示该值？

Question

所以当我点击＆＃34;查看用户记录＆＃34;按钮我想显示视图控制器的分数和实时值，并将其作为数组存储在plist中。然后，plist中的那些值将显示在表格视图中

尝试在plist文件中添加值。

NSString* plistPath = nil;
NSFileManager* manager = [NSFileManager defaultManager];
if (plistPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"Contents/Info.plist"]) 
{
    if ([manager isWritableFileAtPath:plistPath]) 
    {
        NSMutableDictionary* infoDict = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
        [infoDict setObject:[NSNumber numberWithBool:hidden] forKey:@"LSUIElement"];
        [infoDict writeToFile:plistPath atomically:NO];
        [manager changeFileAttributes:[NSDictionary dictionaryWithObject:[NSDate date] forKey:NSFileModificationDate] atPath: [[NSBundle mainBundle] bundlePath]];
    }
}

这是从plist文件中获取值。

 NSBundle* mainBundle = [NSBundle mainBundle]; 

// Reads the value of the custom key I added to the Info.plist
    NSString *value = [mainBundle objectForInfoDictionaryKey:@"key"];

//Log the value
NSLog(@"Value = %@", value);

---

// Get the value for the "Bundle version" from the Info.plist
[mainBundle objectForInfoDictionaryKey:@"CFBundleVersion"];

// Get the bundle identifier
[mainBundle bundleIdentifier];

我希望这段代码对你有用。
