iOS的存储方式很多，今天我们来看看plist的简单存储与读取

存储和修改plist文件

+ (void)saveKeywords:(NSArray *)array {
    if (!IS_VALID_ARRAY(array)) {
        return;
    }
    NSString *path = [TYTools getDocumentsPath];
    path = [path stringByAppendingPathComponent:@"TYKeywords.plist"];
    BOOL succ = [array writeToFile:path atomically:YES];
    if (succ) {
        NSLog(@"存储成功");
    } else {
        NSLog(@"存储失败");
    }
}

获取plist文件数据

+ (NSArray *)getKeyWordsFromPlist {
    NSString *path = [TYTools getDocumentsPath];
    path = [path stringByAppendingPathComponent:@"TYKeywords.plist"];
    return [NSArray arrayWithContentsOfFile:path];
}

删除plist文件，即删除数据

+ (void)removeAllKeywords {
    NSString *path = [TYTools getDocumentsPath];
    path = [path stringByAppendingPathComponent:@"TYKeywords.plist"];
    NSError *error;
    [[NSFileManager defaultManager] removeItemAtPath:path error:&error];
    if (error == nil) {
        NSLog(@"删除成功");
    }
}

附加方法 - 获取Documents路径

+ (NSString *)getDocumentsPath {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    return [paths objectAtIndex:0];
}
