standardUserDefaults 的使用

偏好设置的工具方法

+ (void)setObject:(id)value forKey:(NSString *)key{
    [[NSUserDefaults standardUserDefaults] setObject:value forKey:key];
    [[NSUserDefaults standardUserDefaults] synchronize];
}
+ (id)objectForKey:(NSString *)key{
    return [[NSUserDefaults standardUserDefaults] objectForKey:key];
}

例子： 是否展示过版本新特性，也即是引导页

-(void)setBShowIntroduce:(BOOL)bShowIntroduce
{
    //    [SessionMgr Instance].strOrderAmount = bShowIntroduce;

    [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithBool:bShowIntroduce] forKey:@"bShowIntroduce"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}


/**
 此版本是否提示过文案

 */
-(BOOL)bShowIntroduce
{
    //    return [SessionMgr Instance].strOrderAmount;

    NSNumber *numShowIntroduce = [[NSUserDefaults standardUserDefaults] objectForKey: @"bShowIntroduce"];

    return [numShowIntroduce boolValue];
}
