解决方法
是的,它们不能像NSUserDefaults那样保存.
我正在写一个代码,请看看,更多的学习去看苹果docs好的.
代码在这里：
//保存
NSData *dataSave = [NSKeyedArchiver archivedDataWithRootObject:yourArrayToBeSave]]; [[NSUserDefaults standardUserDefaults] setObject:dataSave forKey:@"array"]; [[NSUserDefaults standardUserDefaults] synchronize]; // this will save you UserDefaults
//用于检索
NSData *data = [[NSUserDefaults standardUserDefaults] objectForKey:@"array"]; NSArray *savedArray = [NSKeyedUnarchiver unarchiveObjectWithData:data];
