问题描述
当我尝试使用以下代码写入文件时:
When i try to write to file with this code:
NSString *path = [[NSBundle mainBundle] pathForResource:@"default" ofType:@"txt"];
NSError *error = nil;
NSString*s = @"some text";
BOOL successful = [s writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:&error];
NSLog(@"%@",error);
NSLog(@"%d",successful);
什么都没发生。 NSLog说:
Nothing happens. NSLog says:

推荐答案
这是因为您正在编写主捆绑包,请尝试以下操作:
That's because you're writing over the main bundle try this:
NSString *applicationDocumentsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *storePath = [applicationDocumentsDir stringByAppendingPathComponent:@"default.txt"];
在这里,我们试图覆盖我们的应用程序文档目录。因为你不能在主捆绑包上写东西
Here we're trying to write over our app Documents directory. Because you can't write on the main bundle
