我想解析一个复杂的CSV文件.我在网上搜索了一些来源,但我只找到了带有昏迷和引号的简单csv的读者.但我的还包含"{","["和":"以创建组,子组......

如何从这种csv中检索正确的NSArray或NSDictionary？或者你知道一个伟大的(伟大的!)csv阅读器/解析器？

谢谢 !

这是一个例子:

如何连接到受密码保护的特定wifi？

场景:有四个wifi网络,但我的应用程序需要连接到特定的一个,同时提供密码.

我正在努力与一些iOS开发,我希望有人能够帮助我提出建议.我想实现一堆看起来像一副牌的UIViews.用户应该可以通过触摸来刷出"卡片".我想到了带有pagingEnabled的UIScrollViews,给人的印象是卡片是分开的.但是,UIScrollView可以从左侧或右侧水平滑动.我希望我的卡片组位于屏幕中间,这样用户就可以从卡片上刷卡而不会看到卡片出现在左侧或右侧.此外,我正在考虑使用触摸方法(touchesBegan,touchesMoved等)来移动视图.它可以工作...但我担心我不能重现卡的正确机制(摩擦,弹跳效果,当滑动短,等等..).

有人可以指点我一个适当的技术或建议一些教程？我已经做了一些研究,但我找不到任何有用的东西.

这是我想要实现的效果的图像.

而我想要实现的是将卡片刷出卡座.

非常感谢!

我真的不确定它是什么(如果它是一个指针数组,或指针数组的数组???),但当我通过调试器踩它时它给了我0xCDCDCDCD,意味着内存被分配,但未初始化.谁能告诉我如何初始化它？

谢谢.

char* (*vars)[4];

我尝试过这样的东西,但它会产生编译错误:

for (int i = 0; i < 4; i++)
    vars[i] = new char*[new char*][4]; // error C2440: 'initializing' : cannot convert from 'char **' to 'unsigned int'

我的阵列:

NSMutableArray *squareLocations;

CGPoint dotOne = CGPointMake(1, 1);
[squareLocations addObject:[NSValue valueWithCGPoint:dotOne]];

CGPoint dotTwo = CGPointMake(10, 10);
[squareLocations addObject:[NSValue valueWithCGPoint:dotTwo]];

CGPoint dotThree = CGPointMake(100, 100);
[squareLocations addObject:[NSValue valueWithCGPoint:dotThree]];

int num = [squareLocations count];

for (int i = 0; i < num; i++)
{
    NSValue *pointLocation = [squareLocations objectAtIndex:i];
    NSLog(@"%@", pointLocation);
}

当我要求squareLoctions对象计数时,它返回零？但就在上面要求计数我添加了三个NSValue对象??? 有人有主意吗？
