如何將陣列替換爲iPhone中的plist？

我的plist中的數據如何將陣列替換爲iPhone中的plist？

ArrayKey 

item0 100 
item1 200 
item2 300

我的功能是

- (IBAction)Save:(id)sender 
{ 
    NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"]; 
    NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] 
             initWithContentsOfFile:plistPath]; 
    NSMutableArray * array = (NSMutableArray *)[dictionary valueForKey:@"ArrayKey"]; 
    [array replaceObjectAtIndex:0 withObject:textView1.text]; 
    [array replaceObjectAtIndex:1 withObject:textView2.text]; 
    [array replaceObjectAtIndex:2 withObject:textView3.text]; 
    NSLog(@"Array is :%@",dictionary); 
    [dictionary writeToFile:plistPath atomically:YES]; 
}

哪裏是錯誤的。請幫助！

謝謝。
