简单的NSTextList问题 [英] Simple NSTextList question

问题描述

我试图使用 NSTextList 在多行 NSTextField 中显示数字列表，但它不是

$ b （IBAction）displayResult：（id）sender
{
NSTextList * list = [[NSTextList alloc] initWithMarkerFormat：self.markerFormat options：1]; // {Decimal}以标记格式传递
NSMutableParagraphStyle * paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[paragraph setTextLists：[NSArray arrayWithObject：list]];
[list release];
NSDictionary * attributes = [NSDictionary dictionaryWithObjectsAndKeys：paragraph，NSParagraphStyleAttributeName，nil];
NSAttributedString * attrString = [[NSAttributedString alloc] initWithString：self.inputString attributes：attributes]; // input string is- George \\\
Thomas \\\
Ashok
[self setOutputString：attrString];
[attrString release];
[paragraph release];
}

输入为 -

  George 
 
 Thomas 
 
 Ashok 
  

输出应为 -

  1 George 
 
 2 Thomas 
 
 3 Ashok 
  

但输出显示is -

  George 
 
 Thomas 
 
 Ashok 
  
 
 
 
任何人都可以建议如何实现预期的输出？
解决方案
您正在做的一切看起来都很好，华丽地给我:) 
输入字符串有一个问题
尝试这个，
  NSTextList * list1 = [[NSTextList alloc] initWithMarkerFormat：@{decimal}options：0]; // {Decimal}以标记格式传递
 NSMutableParagraphStyle * paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy]; 
 [list1 setStartingItemNumber：1]; 
 [paragraph setTextList：[NSArray arrayWithObject：list1]]; 
 
 NSDictionary * attributes = [NSDictionary dictionaryWithObjectsAndKeys：paragraph，NSParagraphStyleAttributeName，nil]; 
 NSMutableAttributedString * attrString = [[NSMutableAttributedString alloc] initWithString：[NSString stringWithFormat：@\t％@ Suhas \\\
 \t％@ Devarshi \\\
 \t％@ Rohith\\\
， [list1 markerForItemNumber：1]，[list1 markerForItemNumber：2]，[list1 markerForItemNumber：3]] attributes：attributes]; 
 [self.text setStringValue：attrString]; // self.text是一个NSTextField实例。请仔细忽略编译器警告:) 
  
 
I am trying to use NSTextList to display a numeric list in a multi-line NSTextField but it is not working as intended.

The sample code used is:
- (IBAction)displayResult:(id)sender
{
    NSTextList *list = [[NSTextList alloc] initWithMarkerFormat:self.markerFormat options:1]; // {Decimal} passed as marker format
    NSMutableParagraphStyle *paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    [paragraph setTextLists:[NSArray arrayWithObject:list]];
    [list release];
    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:paragraph, NSParagraphStyleAttributeName, nil];
    NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:self.inputString attributes:attributes] ; // input string is- George \n Thomas \n Ashok
    [self setOutputString:attrString]; 
    [attrString release];
    [paragraph release];
}
The input is - 
George 

Thomas 

Ashok
The output should be - 
1 George

2 Thomas

3 Ashok
but output it is showing is -
George 

Thomas 

Ashok
Can anyone suggest how to achieve the expected output?
解决方案
Everything you are doing looks fine and ornately to me:) 
    There is a problem with your input string
    Try this,
NSTextList *list1 = [[NSTextList alloc] initWithMarkerFormat:@"{decimal}" options:0]; // {Decimal} passed as marker format
NSMutableParagraphStyle *paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[list1 setStartingItemNumber:1];
[paragraph setTextLists:[NSArray arrayWithObject:list1]];

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:paragraph, NSParagraphStyleAttributeName, nil];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"\t%@ Suhas \n \t%@ Devarshi \n \t%@ Rohith\n", [list1 markerForItemNumber:1],[list1 markerForItemNumber:2],[list1 markerForItemNumber:3]] attributes:attributes] ;
 [self.text setStringValue:attrString];//self.text is a NSTextField instance. kindly ignore the compiler warning:)
