iphone - 写入文件 :atomically deprecate Warning

Question

我想将一个用户名的 textField 值写入名为 login.txt 的文件。

我的代码:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

// the path to write file
loginFilePath= [documentsDirectory stringByAppendingPathComponent:@"Login.txt"];
NSString *userName=[nameText text];
[userName writeToFile:loginFilePath atomically:YES];

我收到警告，因为“wrtieToFile:atomically:”已被弃用。

Answer 1

因为它已被弃用，所以使用:

- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)useAuxiliaryFile encoding:(NSStringEncoding)enc error:(NSError **)error;

代替 writeToFile:atomically
