读取方法

//获得plist文件的路径

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"SearchHistory" ofType:@"plist"];

//从路径中读取文件，取决于你的plist文件里的属性

_historyArray=[[NSMutableArray alloc] initWithContentsOfFile:plistPath];


写入方法

//获得plist文件的路径

NSString*plistPath = [[NSBundlemainBundle]pathForResource:@"SearchHistory"ofType:@"plist"];

//你也可以用这种获得路径的方法，反正我不怎么用

//获取应用程序沙盒的Documents目录

NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);

NSString *plistPath2 = [paths objectAtIndex:0];

//得到完整的文件名

//NSString *filename=[plistPath2 stringByAppendingPathComponent:@"SearchHistory.plist"];

//输入写入

[_historyArray writeToFile:filename atomically:YES];
