我想在applicationSupportDirectory中创建一个目录.我的理解是applicationSupportDirectory不允许用户查看其中的数据.这就是我选择它的原因.但是,我在下面使用的代码似乎失败了,我不知道为什么.
谁能告诉我我做错了什么？谢谢！
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory,NSUserDomainMask,YES);
NSString *applicationDirectory = [paths objectAtIndex:0]; // Get directory
NSString *dataPath = [applicationDirectory stringByAppendingPathComponent:@"drawings"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){
NSError* error;
if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error])
;// success
else
{
NSLog(@"Failed");
}
}
}
解决方法
NSString *directoryName = @"drawing";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory,YES);
NSString *applicationDirectory = [paths objectAtIndex:0];
NSString *filePathAndDirectory = [applicationDirectory stringByAppendingPathComponent:directoryName];
NSError *error;
if (![[NSFileManager defaultManager] createDirectoryAtPath:filePathAndDirectory
withIntermediateDirectories:YES
attributes:nil
error:&error])
{
NSLog(@"Create directory error: %@",error);
}
希望它会对你有所帮助
