怎么写AppName-Info.plist

添加了一个key，名为App，到AppName-Info.plist 中。通过下面代码可以获取它的值：

NSBundle *mainBundle;
mainBundle = [NSBundle mainBundle];

NSString *value = [mainBundle objectForInfoDictionaryKey:@"App"];

NSLog(@"App: %@",value);

但是我用了很多方法都不能改变这个值，有实现方法么？请大家帮忙啊，谢谢。

考虑使用NSUserDefaults`

如果你想修改bundled .plist试试这个：

    NSString* plistFilePath = nil;
NSFileManager* manager = [NSFileManager defaultManager];
if ((plistFilePath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"mySpecial/PathTo.plist"])) 
{
    if ([manager isWritableFileAtPath:plistFilePath]) 
    {
        NSMutableDictionary* infoDictioio = [NSMutableDictionary dictionaryWithContentsOfFile:plistFilePath];
        [infoDictio setObject:@"foo object" forKey:@"fookey"];
        [infoDictio writeToFile:plistFilePath atomically:NO];
        [manager setAttributes:[NSDictionary dictionaryWithObject:[NSDate date] forKey:NSFileModificationDate] ofItemAtPath:[[NSBundle mainBundle] bundlePath] error:nil];
    }
}
