Tips:沙盒目录和访问方法

前言

老是忘记沙盒目录和访问方法，写了个demo和流程图做为复习

demo

- (void)viewDidLoad {
    [super viewDidLoad];
    // 沙盒目录
    NSString *home = NSHomeDirectory();
    // 沙盒下document目录
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docDir = [paths objectAtIndex:0];
    //沙盒下library/Caches
    NSArray *paths1 = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    NSString *cachesDir = [paths1 objectAtIndex:0];
    //沙盒下tmp 目录
    NSString *tmp = NSTemporaryDirectory();
    
    // library/prefrence目录下保存一个plist文件，是NSUserDefaults用来实现磁盘缓存的文件
    [[NSUserDefaults standardUserDefaults] setObject:@"zhouming" forKey:@"name"];
    [[NSUserDefaults standardUserDefaults] synchronize];
      
}
