喜内存管理我有2类之一plisreader其下面的代码与代码
//

// NationalAntemsAndFlags

@interface PlistReader : NSObject
{
NSDictionary *temp;
}
@property (nonatomic,retain) NSDictionary *temp;
-(int)LengthOfPList;

-(void)initWithFileName:(NSString*)fileName;

@end
//实现文件

#import "PlistReader.h"
@implementation PlistReader
@synthesize temp;
-(id)init
{
if(self =[super init])
{
}
return self;
}
-(void)initWithFileName:(NSString*)fileName
{
// Data.plist code
// get paths from root direcory
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
// get documents path
NSString *documentsPath = [paths objectAtIndex:0];
// get the path to our Data/plist file
NSString *plistPath = [documentsPath stringByAppendingPathComponent:[fileName stringByAppendingString:@"plist"]];
// check to see if Data.plist exists in documents
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath])
{
// if not in documents, get property list from main bundle
plistPath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"plist"];
}
// read property list into memory as an NSData object
NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];
NSString *errorDesc = nil;
NSPropertyListFormat format;
// convert static property liost into dictionary object
temp =(NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];
if (!temp)
{
NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
}
// assign values
}
-(int)LengthOfPList
{
return temp.count;
}
-(id)GetTheObjectById:(NSString*)ObjId
{
return [temp objectForKey:ObjId];
}
-(id)getCountryInfoById:(int)objId
{
NSString *objsId = [NSString stringWithFormat:@"%d",objId];
NSDictionary *CDirectory = (NSDictionary*) [self GetTheObjectById:objsId];
int count = CDirectory.count;
if(count>0)
{
CountryClass *objCountry = [[CountryClass alloc] init];
objCountry.Name= [CDirectory objectForKey:@"Name"];
objCountry.LocationX =[[CDirectory objectForKey:@"PositionX"] intValue];
objCountry.LocationY = [[CDirectory objectForKey:@"PositionY"] intValue];
objCountry.ImageUrl = [CDirectory objectForKey:@"ImageUrl"];
objCountry.AnthemUrl =[CDirectory objectForKey:@"AnthemUrl"];
objCountry.ShortDetail =[CDirectory objectForKey:@"short Info"];
objCountry.completeDetails = [CDirectory objectForKey:@"Details"];
id ObjCountryInfo= objCountry;
[objCountry release];
return ObjCountryInfo;
}
return NULL;
}
-(void)dealloc
{
NSLog(@"dealloc plist");
[temp release];
[super dealloc];
}
@end
，另一个是已以下代码
国家类//
// CountryClass.h
// NationalAntemsAndFlags
//
// Created by mac on 12/17/11.
// Copyright (c) 2011 __MyCompanyName__. All rights reserved.
//
#import <Foundation/Foundation.h>
@interface CountryClass : NSObject
{
NSString *Name ;
NSString *ImageUrl;
NSString *AnthemUrl;
NSString *ShortDetail;
NSString *completeDetails;
int LocationX ;
int LocationY ;
}
@property (nonatomic,retain) IBOutlet NSString *Name;
@property (nonatomic,retain) IBOutlet NSString *ImageUrl;
@property (nonatomic,retain) IBOutlet NSString *AnthemUrl;
@property (nonatomic,retain) IBOutlet NSString *ShortDetail;
@property (nonatomic,retain) IBOutlet NSString *completeDetails;
@property (nonatomic) IBOutlet int LocationY;
@property (nonatomic) IBOutlet int LocationX;
@end
执行文件
//
// CountryClass.m
// NationalAntemsAndFlags
//
// Created by mac on 12/17/11.
// Copyright (c) 2011 __MyCompanyName__. All rights reserved.
//
#import "CountryClass.h"
@implementation CountryClass
@synthesize Name,ImageUrl,AnthemUrl,ShortDetail,completeDetails,LocationX,LocationY;
@end
所以我在现场称这种类似这样的
-(void)LoadData:(int)countryId
{
CId = countryId;
PlistReader *pList =[[PlistReader alloc]init];
[pList initWithFileName:@"CountryDetails"];
CountryClass *objcountry = (CountryClass*) [pList getCountryInfoById:countryId];
NSString *tempLongDetails = objcountry.completeDetails;
NSString *tempShortDetails = objcountry.ShortDetail;
NSString *fileName = objcountry.ImageUrl ;
CCSprite *flag ;
NSString * fullPath = [[NSBundle mainBundle] pathForResource: [fileName stringByDeletingPathExtension]
ofType: [fileName pathExtension]
inDirectory: @"CountryFlags"];
NSLog(fullPath);
if (fullPath)
{
UIImage *theImage = [UIImage imageWithContentsOfFile: fullPath];
if (theImage)
{
flag = [CCSprite spriteWithCGImage: [theImage CGImage] key: fileName];
// flag = [CCSprite spriteWithFile:fileName];
flag.position = ccp(200, 265);
flag.scale = .255;
}
}
TextViewTopFlagData = [[UITextView alloc]init];
TextViewTopFlagData.text = tempShortDetails;
TextViewTopFlagData.frame = CGRectMake(260,17, 105, 75);
TextViewTopFlagData.backgroundColor = [UIColor clearColor];
[TextViewTopFlagData setEditable:NO];
TextViewDownFlagData = [[UITextView alloc]init];
TextViewDownFlagData.text = tempLongDetails;
TextViewDownFlagData.frame = CGRectMake(22,240, 242, 61);
TextViewDownFlagData.backgroundColor = [UIColor clearColor];
[TextViewDownFlagData setEditable:NO];
[[[CCDirector sharedDirector]openGLView]addSubview:TextViewTopFlagData];
[[[CCDirector sharedDirector]openGLView]addSubview:TextViewDownFlagData];
[self addChild:flag];
}
@end
，但在功能objcountry年底将是空的或从参考数据任何一个可以解释我，这是为什么happaning
请只包括实际引用您的问题代码正在谈论，这太长了。 – jrturton 2011-12-19 16:40:19
我以为可能是人们无法理解我在说什么，为什么我把所有的代码放在这里主要问题是那个objcountry在函数的末尾丢了值或者被破坏了所以为什么会发生那个 – 2011-12-19 16:45:24
@live.logic你可以使用它下面的“编辑”链接编辑这个问题。无需删除并重新发布。 – 2011-12-22 05:20:03
