将字符串存储到本地和读取

直接上代码：复制粘贴 自己看       懒得解释＃24

NSString*content =@"将字符串存储到本地文件xxxxxxxxxxxxxxxxxxxxxxxxxxxx";

NSString*documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)firstObject];

//(2)拼接上要存储的文件路径(前面自动加上/),如果没有此文件系统会自动创建一个

NSString*newFielPath = [documentsPathstringByAppendingPathComponent:@"aa.txt"];

//(3)将内容存储到指定文件路径

NSError*error =nil;

//字符串写入本地文件参数:(1)要存储内容的文件路径,(2)是否使用原子特性,(3)存储格式

BOOLisSucceed = [contentwriteToFile:newFielPathatomically:YESencoding:NSUTF8StringEncodingerror:&error];

NSLog(@"isSucceed:%hhd",isSucceed);

NSLog(@"newFielPath:%@",newFielPath);

NSString*documentsPath1 = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)firstObject];

//(2)拼接上要存储的文件路径(前面自动加上/),如果没有此文件系统会自动创建一个

NSString*newFielPath1 = [documentsPath1stringByAppendingPathComponent:@"aa.txt"];

//(3)

//读取数据

NSError*error1 =nil;

//(最后也可以&error)

NSString*content1 = [NSStringstringWithContentsOfFile:newFielPath1encoding:NSUTF8StringEncodingerror:nil];

NSLog(@"content1:%@",content1);
