NSFileManager isWritableFileAtPath错误

Question

macApp createFileAtPath失败，我需要在哪里更改？

相同的代码

NSString * folderPath = @"/Users/shang/Downloads";
NSFileManager *manager = NSFileManager.defaultManager;
NSString *fileAtPath = [folderPath stringByAppendingPathComponent:@"BNRootModel0000.h"];
bool isSuccess = [manager createFileAtPath:fileAtPath contents:[@"22222" dataUsingEncoding:NSUTF8StringEncoding] attributes:nil];

bool isExist = [NSFileManager.defaultManager fileExistsAtPath:fileAtPath];
bool isWritable = [NSFileManager.defaultManager isWritableFileAtPath:fileAtPath];

NSLog(@"__%@_%@_%@", @(isWritable), @(isExist), @(isSuccess));

我希望在macApp上工作，但实际情况是失败了

这是一个权限问题。在项目中，功能->应用程序SandBox ->文件访问，更改您的需要，并正常工作！
