Ios 按顺序获取plist数据
我将数据保存在plist中。一旦我的应用被删除并重新安装，我计划通过iCloud获取这些plist数据。我有上传选项，可以将文件发送到云，并在安装新应用时检索。删除/重新安装应用程序后，将检索到plist数据，不会出现任何问题。现在的问题是，我将这样的文件保存在数组中，然后写入plist：Ios 按顺序获取plist数据,ios,objective-c,xcode,plist,Ios,Objective C,Xcode,Plist,我将数据保存在plist中。一旦我的应用被删除并重新安装，我计划通过iCloud获取这些plist数据。我有上传选项，可以将文件发送到云，并在安装新应用时检索。删除/重新安装应用程序后，将检索到plist数据，不会出现任何问题。现在的问题是，我将这样的文件保存在数组中，然后写入plist： Printing description of arrTemp: <__NSCFArray 0x175f7d90>( { Amount = "USD 100.00"; Catego

当新安装应用程序时，我无法将从云检索的数据直接写入我的plist。我必须将plist数据返回到喜欢的数组（最初发布为“打印arrTemp的说明：”），并在我的应用程序安装新的时将其写入我的路径。如何将数据从plist转换成新的数组应该像我最初在“打印arrTemp的描述：”中发布的那样？？请帮助您的plist是一个包含单个元素的数组，它是一个字典。字典是无序的集合。数组已排序，并保留该顺序 此外，您似乎对用于记录数组的格式（这是对数组调用
-descriptionNSArrayNSDictionary问题是您只是将plist作为数据检索，而不知道如何将其反序列化到
NSArrayNSData* data = /* data object containing the plist XML as you posted in your question */;
NSError* error;
NSArray* array = [NSPropertyListSerialization propertyListWithData:data
options:NSPropertyListImmutable
format:NULL
error:&error];
if (!array)
{
NSLog(@"failed to deserialize plist data %@: %@", data, error);
// additional error handling
}
if (![array isKindOfClass:[NSArray class]])
{
NSLog(@"plist data is not an array as expected; data %@; got %@", data, array);
// additional handling for invalid data
}
步骤1：将NSObject类名创建为PList in.h 步骤2：在视图控制器中
In viewDidLoad Method
arrTemp = [PList arrayPlistInit:PUBLIC]; //I think PUBLIC is the plist name.
In viewDidLoad Method after arrTemp
for(int i=0;i<[arrTemp count];i++)
{
NSString *strAmount = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0]valueForKey:@"Amount"]];
NSString *strCategory = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Category"]];
NSString *strCurrency = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0]valueForKey:@"Currency"]];
NSString *strDate= [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Date"]];
NSString *strDateSort = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"DateSort"]];
NSString *strMerchant = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0]valueForKey:@"Merchant"]];
NSString *strPayment = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Payment"]];
NSString *strPurpose = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Purpose"]];
NSString *strSubCategory = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"SubCategory"]];
NSString *strTimeStamp= [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0]valueForKey:@"TimeStamp"]];
NSString *strTips = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Tips"]];
NSString *strUDDate1 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDDate1"]];
NSString *strUDDate2 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDDate2"]];
NSString *strUDNumber1 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0]valueForKey:@"UDNumber1"]];
NSString *strUDNumber2 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDNumber2"]];
NSString *strUDNumber3 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDNumber3"]];
NSString *strUDText1 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDText1"]];
NSString *strUDText2 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDText2"]];
NSString *strUDText3 = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"UDText3"]];
NSString *strUploaded = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Uploaded"]];
NSString *strValue = [NSString stringWithFormat:@"%@",[[arrTemp objectAtIndex:0] valueForKey:@"Value"]];

对于（int i=0；itry，这对您有帮助吗？NSDictionary*dictRoot；NSLog（@“DIC is%@”，dictRoot））；显示空值。Ramanan只需遵循我的代码。这将帮助您解决问题了吗？是否有任何可能的方法将此plist数据转换为数组，如我在“打印arrTemp的说明：”中发布的那样？这是一个数组。您发布了一个包含单个元素的数组，这是一个词汇表，两次都是。这两种表示都显示了相同的数据结构。如果您认为它们不同，您会感到困惑。NSData fileData=documentData；//从iCloud接收的文件**现在我将//NSData转换为str**NSString myString；myString=[[NSString alloc]initWithData:fileData encoding:NSASCIIStringEncoding]；**当NSLog这个“myString”显示正确时。但问题发生在这里NSMutableArray*arrayPlist=[NSMutableArrayWithContentsOfFile:myString]；NSLog->arrayPlist显示空。有问题的第二个代码开始K。您是否创建了Plist（新文件->IOS资源->属性列表）对于那些设置键？我现在会清楚地告诉你。如果你在Plist中设置了键，你可以简单地使用我上面的代码。那是在Bundle中。这就是为什么我们必须提到[[NSBundle mainBundle]pathForResource:plistName of type:@“Plist”]的原因。然后我们可以从Plist到数组获取这些值。

arrTemp = [PList arrayPlistInit:PUBLIC]; //I think PUBLIC is the plist name.
