Objective-C使用字符串创建文本文件

#import<Foundation/Foundation.h>

NSString *fileContents = @"这是一个文本文件";
NSString *fileName = @"myFile.txt";
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:fileName];

BOOL success = [fileContents writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:nil];

if (success) {
    NSLog(@"文件创建成功");
} else {
    NSLog(@"文件创建失败");
}
