Question

ios 开发使用代码创建文件智能放在沙盒吗，除了沙盒能放在工程目录下吗

Answer 1

NSString *home = NSHomeDirectory();//获取沙盒路径
//拼接Documents路径
//NSString *docPath = [home stringByAppendingStringt:@"/Documents"];
NSString *docPath = [home stringByAppendingPathComponent:@"Documents"];
NSString *filePath = [docPath stringByAppendingPathComponent:@"data.plist"];

NSArray *array = @[@1,@2,@"123"];
//只有具备writeToFile的对象才能使用plist存储，NSArray
[array writeToFile:filePath atomically:YES];

主要是获取路径，然后把文件写到这个路径里就好了
