的plist值替換添加

Question

喜，而不是我要補充一些數據的plist在**在下面的圖像格式如下像**

但實際IAM越來越是喜歡這裏

請幫助我的代碼，這是...

-(void)updatePlist 
{ 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *pathOfPricePlist= [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Price.plist"]; 
    NSMutableDictionary *mutableDictionary=[[NSMutableDictionary alloc]init]; 
    NSMutableArray *finalList=[[NSMutableArray alloc]init]; 
    for(int i=0;i<[sharedManager.bookidList count];i++) { 

     [mutableDictionary setValue:[sharedManager.sharedProductPrice objectAtIndex:i] forKey:@"price"]; 
     [mutableDictionary setValue:[sharedManager.bookidList objectAtIndex:i] forKey:@"booknumber"]; 

     NSLog(@"%@",mutableDictionary); 
     [finalList addObject:mutableDictionary]; 
     NSLog(@"%@",finalList); 
    } 

    [finalList writeToFile:pathOfPricePlist atomically:YES]; 

}

您需要在for循環的每一步創建一個新的mutableDictionary。像這樣：

-(void)updatePlist 
{ 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *pathOfPricePlist= [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Price.plist"]; 

    NSMutableArray *finalList=[[NSMutableArray alloc]init]; 
    for(int i=0;i<[sharedManager.bookidList count];i++) { 

     NSMutableDictionary *mutableDictionary=[[NSMutableDictionary alloc]init]; 


     [mutableDictionary setValue:[sharedManager.sharedProductPrice objectAtIndex:i] forKey:@"price"]; 
     [mutableDictionary setValue:[sharedManager.bookidList objectAtIndex:i] forKey:@"booknumber"]; 

     NSLog(@"%@",mutableDictionary); 
     [finalList addObject:mutableDictionary]; 
     NSLog(@"%@",finalList); 
    } 

    [finalList writeToFile:pathOfPricePlist atomically:YES]; 

} 

否則，您只需在該數組中重複添加相同的字典。
