以编程方式设置NSTextField的文本 [英] Setting the text of an NSTextField programmatically

问题描述

我有一个建立在IB（Xcode 4）上的GUI。

它有一个静态文本字段连接到NSTextField。从XML文件读取信息后，应该将文本更改为来自XML的任何内容

I have a GUI built on IB (Xcode 4).
It has a Static Text field connected to an NSTextField. After reading the information from an XML file it's supposed to change the text to whatever it is coming from the XML

.h如下：

IBOutlet NSTextField * DataBaseLocation;

.m

NSMutableArray* DBLoc = [[NSMutableArray alloc] initWithCapacity:1];
NSXMLElement* root  = [doc rootElement];
NSArray* DBarray = [root nodesForXPath:@"//DataBaseLocation" error:nil];
for(NSXMLElement* xmlElement in DBarray)
    [DBLoc addObject:[xmlElement stringValue]];

NSString * DBLocationString = [DBLoc objectAtIndex:0];
[DataBaseLocation setStringValue:DBLocationString];

NSLog(@"DBLoc: %@", DBLoc);

NSLog 显示 DBLoc 有正确的字符串，但文本字段为空，永远不会设置。

The NSLog shows that DBLoc has the correct string, yet the Text Field is empty and never gets set.

是的，我检查了IB中的连接。
任何想法？感谢！

yes, I checked the connections in IB. Any ideas? thanks!

I needed to initialize the NSXMLDocument with NSXMLDocumentTidyXML like:

NSXMLDocument* doc = [[NSXMLDocument alloc] initWithContentsOfURL: [NSURL fileURLWithPath:input] options:NSXMLDocumentTidyXML error:NULL];
