整个 App 包对于 iOS 应用程序是只读的，因此您不能在运行时添加任何资源。例如，您可以为此目的使用 Library/Caches 文件夹。参见URLsForDirectory:inDomains:查找该目录的路径。

例如：

// Path to a plist file in Caches directory:
NSURL *cacheDir = [[[NSFileManager defaultManager] URLsForDirectory:NSCachesDirectory inDomains:NSUserDomainMask] lastObject];
NSURL *plistFile = [cacheDir URLByAppendingPathComponent:@"myresource.plist"];

// write array to plist file:
[myArray writeToURL:plistFile atomically:NO];

// read array from plist file and make it mutable:
NSMutableArray *secondArray =  [[NSArray arrayWithContentsOfURL:plistFile] mutableCopy];
