iOS开发：Plist文件读写。1、读取+写入plist；2、根据plist节点内容创建UITab

iOS开发：Plist文件读写。1、读取+写入plist；2、根据plist节点内容创建UITab

//获取plist地址

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

NSMutableDictionary *dataDic = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath]; //根据你存入的类型取出对应的数据。

//添加一项内容

[dataDic setObject:arr forKey:@"upgradeData"];

//获取应用程序沙盒的Documents目录

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

NSString *plistPath1 = [paths objectAtIndex:0];

//得到完整的文件名

NSString *filename=[plistPath1 stringByAppendingPathComponent:@"UpgradeDataArray.plist"];

//输入写入

BOOL fl = [dataDic writeToFile:filename atomically:YES]; //写入

提问容易，回答不易，且问且采纳！！
