plist操作

很早以前写了一个库，结果找不到了。再害怕遗忘，随便整理了几点操作，以后想起来再补充。

//.h

#import <Foundation/Foundation.h>


@interface BPlistFileManager : NSObject {
@private NSMutableString* filename_;
@private NSString *path;
    
}

+(BPlistFileManager*)getInstance;

-(void)setPlistName:(NSString*)filename withPath:(NSString*)filepath;

-(void)setPlistName:(NSString*)filefullname;

-(void)createPlistWithArray:(NSMutableArray*)array;

-(void)createPlistWithDictionary:(NSMutableDictionary*)dictionary;


-(NSArray*)readPlistwithArray;
-(NSDictionary*)readPlistwithDictionary;

@end

//.m
static BPlistFileManager* instance;

@implementation BPlistFileManager

-(id)init
{
    self = [super init];
    if (self) {
 
    }
    return self;
}
+(BPlistFileManager*)getInstance
{
    if (instance==nil) {
        instance = [[BPlistFileManager alloc] init];
                
    }
    return instance;
}

-(void)setPlistName:(NSString*)filename withPath:(NSString*)filepath
{
    if(filepath==nil)
    {
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
        path = [paths objectAtIndex:0];

    }
    else
    {
        path =[filepath retain];
    }
    
    if(filename!= nil)
    {
     filename_ = [NSMutableString stringWithString:filename];   
    }
    filename_ = [NSMutableString stringWithString:[path stringByAppendingPathComponent:filename_]];
}

-(void)setPlistName:(NSString*)filefullname
{
    if(filefullname!= nil)
    {
        filename_ = [NSMutableString stringWithString:filefullname];   
    }
}

-(void)createPlistWithArray:(NSMutableArray*)array
{
    if (array!=nil)
    [array writeToFile:filename_ atomically:YES];
    
}

-(void)createPlistWithDictionary:(NSMutableDictionary*)dictionary
{
    if(dictionary != nil)
    [dictionary writeToFile:filename_ atomically:YES];
}


-(NSArray*)readPlistwithArray
{
    NSArray *array = [NSArray arrayWithContentsOfFile:filename_];
    
   // [[NSArray alloc] initWithContentsOfFile:filename_];
    return [array autorelease];
}
-(NSDictionary*)readPlistwithDictionary
{
    NSDictionary* dic = [NSDictionary dictionaryWithContentsOfFile:filename_];
    return [dic autorelease];
    
}

@end

//main.m中的操作

BPlistFileManager *obj = [BPlistFileManager getInstance];

    //create file
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    NSString* path = [paths objectAtIndex:0];
    NSString* filename =@"test.plist";
    [obj setPlistName:filename withPath:path];
     NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"test1",@"test2", nil];
    [obj createPlistWithArray:array];

    
    //read file
    NSArray *arrayobj = [obj readPlistwithArray];
    for(id obj in arrayobj)
    {
        NSLog(@"obj:%@",obj);
    }
    
    //read existed file.
    NSBundle *thisBundle = [NSBundle mainBundle];
    NSString* commonDictionaryPath  = [thisBundle pathForResource:@"dic" ofType:@"plist"];
    if(commonDictionaryPath != nil)
    {
        [obj setPlistName:commonDictionaryPath];
        NSDictionary *dic = [obj readPlistwithDictionary];
        NSDictionary *subdic=[dic objectForKey:@"dic"];
        NSString* name =[subdic objectForKey:@"name"];
        NSLog(@"name:%@",name);
        NSString* address =[subdic objectForKey:@"address"];
        NSLog(@"address:%@",address);
    }
