假设我的游戏中有以下数据.我用cocos2d开发了游戏.

Name    Score
Sagar   10000
Amit     2000
Vishal     90

以上数据存储在plist文件中.

Plist有一个数组作为root.

其中有10个字典.

每个字典都有两个值:

• 字符串值 - 名称
• 数值 - 得分

我用的时候

NSMutableArray *x=[[NSMutableArray alloc] initWithContentsOfFile:@"Sagar.plist"];

我想按分数对这个可变数组进行排序.

可能吗？

我正在使用以下行创建一个带有CGRects的NSArray:

[self setMyArray:[NSArray arrayWithObjects:[NSValue valueWithCGRect:CGRectMake(x,y,z,a)], [NSValue valueWithCGRect:CGRectMake(x,y,z,a)], nil]]

然后,我经常尝试更新数组中的CGrects,如下所示:

for (NSValue *bound in myArray)
  {
   CGRect myRect = [bound CGRectValue];
   myRect.origin.y += 2;
  }

但是这不起作用,当循环再次运行时,原点仍然相同.我假设这与NSValue包装器有关？,我该怎么做才能在数组中实际更新该值？谢谢.

有人可以帮我一些代码来检查NSArray中的重复项是否有针对性C.我在vb.net做了我想要的但是翻译对我来说很难.

'True means no duplicates'
Public Shared Function checkDuplicate(ByVal list As ArrayList) As [Boolean]
    Dim [set] As New HashSet(Of Integer)
    For i As Integer = 0 To list.Count - 1
        Dim val As Boolean = [set].Add(list(i))
        If val = False Then
            Return val
        End If
    Next
    Return True
End Function

嘿伙计们,我想知道如何在数组中找到特定类型对象的对象数.例如,我在随机位置的NSMutableArray中有6个'云',我在这个NSMutableArray中也有4个'龙'.

我怎样才能收集整数6？

我正在思考以下问题:

int z = [[SomeClass *clouds in _somearray] count];

任何帮助将不胜感激.Thnx,奥利弗.

我只是需要一些帮助来创建一个可以存储多个词典的数组.我有 :

.H

NSArray * projects;
NSDictionary *project1;
NSDictionary * project2;

.M

projects = /* What should I write here to store the
              above two dictionaries in my array.   */

谢谢,

所以我不断遇到这个崩溃并打破我的代码,但我无法确切地知道它来自哪里.Xcode没有在与此相关的行上中断,我查看了所有的线程堆栈,但没有一个显示中断.这是我得到的:

*** Terminating app due to uncaught exception 'NSGenericException', reason: '*** 
Collection <CALayerArray: 0x17746b10> was mutated while being enumerated.'

我的问题是,我如何找到这个数组的位置？有没有办法通过地址在Xcode控制台中查找它,以指出我到底发生了什么？我只是通过关注我的代码找不到我会改变某些数组的位置.

我有一个NSArray包含NSDictionary客户数据.我使用的NSPredicate过滤array,并使之通过ViewControllers用segues.我正处于一个阶段,我想改变存储在其中的键的一些值dictionary.这怎么可以实现？

我的prepareForSegue方法

if ([[segue identifier] isEqualToString:@"showClients"]) {
            // Detect selected row
            NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
            // Extract value from the Clinic_Location attribute
            NSString *cString = [[_clinicList valueForKey:@"Clinic_Location"] objectAtIndex:indexPath.row];
            NSLog(@"Row pressed: %@", cString);

            // Set predicate where Clinic_Location equals the clinic string extracted from the selected row
            NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Clinic_Location == %@", cString];
            // Filter the client array using this predicate
            filteredClientArray …

StackOverflow上已经存在一些类似的问题.我确实检查了它们,并且在大多数情况下它返回nil,因为它NSMutableArray尚未初始化.但在我的情况下,我做了初始化.

这是我的代码的一部分:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.storedTimeZones = [[NSMutableArray alloc] init];
    NSData *storedData = [[NSUserDefaults standardUserDefaults] dataForKey:@"timeZones"];

    if (storedData != nil ) {
        self.storedTimeZones = [NSKeyedUnarchiver unarchiveObjectWithData:storedData];
    }

    NSString *str = [self.smallRegionArray[indexPath.row] stringByReplacingOccurrencesOfString:@"_" withString:@" "];
    [self.storedTimeZones addObject: str];
    NSLog(str); //the string was printed successfully.
    NSLog(@"%lu", (unsigned long)self.storedTimeZones.count); //'0' was printed
}

更新 @Caleb是对的,[NSKeyedUnarchiver unarchiveObjectWithData:storedData返回零.我解决了这个问题:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.storedTimeZones = [[NSMutableArray alloc] init];
    NSData *storedData = [[NSUserDefaults standardUserDefaults] dataForKey:@"timeZones"];
    NSMutableArray *ary = …

我在这段代码中做错了什么？

为什么我会收到错误？

"类型'NSMutableArray'的值没有成员'追加'"

    static func saveUserData()
    {
        let item:NSDictionary = ["TIME":"12:00","LOCATION":"here"]
        let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
        let documentsDirectory = paths[0]
        let filePath = documentsDirectory + "/datafile.dat"
        var readArray:NSMutableArray? = NSMutableArray(contentsOfFile: filePath)

        if var array = readArray {

            print("loaded array - appending..." )

           // PROBLEM IS HERE 
             var damnArray:NSMutableArray = array
             damnArray.append(item)
         } else {
           //
         }
    }

我有保存以下值的数组:

globalarray_beacon: (
"(01000466)",
"(01000008)",
"(01000003)",
"(01000001)",
"(01000006)",
"(01000004)",
"(01000007)",
"(01000005)",
"(01000469)",
"(01000468)",
"(01000420)",
"(01000002)",
"(01000444)",
"(01000463)",
"(01000468)",
"(01000466)",
"(01000001)",
)

我想将此值转换为以下内容:

globalarray_beacon: ( 
01000468,
01000004,
01000006,
01000420,
01000444,
01000466,
01000469,
01000003,
01000005,
01000008,
01000001,
01000007,
01000002
)

try1.

NSArray *items = [theString componentsSeparatedByString:@" " "];

try2.

 NSString *stringWithoutSpaces = [myString 
  stringByReplacingOccurrencesOfString:@"()" withString:@""];

try3.

  for (int i=0; i<array_lastname.count; i++) {


   [array_data addObject:[[array_lastname objectAtIndex:i] componentsSeparatedByString:@"()"]];

}

如何转换数组的值我必须尝试很多东西.如何将字符串值转换为数据.提前致谢.
