iphone - 如何获取字典值计数的数组

Question

我有一个字典键值对数组，但无法获取字典计数数组。它显示不兼容的整数到指针转换 NSsting ..

这是我的源代码

NSString *mCnt = [[gluClkDetailArray valueForKey:@"clkIndependentItem"] count];
NSLog(@"COUNT: %@", mCnt);

请帮我解决这个问题。提前致谢

Answer 1

count 返回纯整数类型，而不是 NSString 对象。

NSInteger *mCnt = [[gluClkDetailArray valueForKey:@"clkIndependentItem"] count];
NSLog(@"COUNT: %d", mCnt);

Answer 2

尝试这个：

NSInteger *anyInt = [[YourLovelyArray valueForKey:@"YourSweetyKey"] count];
NSLog(@"COUNT: %d", anyInt);

Answer 3

NSInteger mCnt = [[gluClkDetailArray valueForKey:@"clkIndependentItem"] count];
NSLog(@"Count is: %d", mCnt);

Answer 4

NSInteger *integ = [[yourArray valueForKey:@"keyvalue"] count];
NSLog(@"COUNT: %d", integ);

这样做:)
