无法在NSTextView中设置文本

Question

::Edit:: It works now? haha, maybe I just didn't save my latest IB...who the hell knows. Thanks!

Hey,

This is my first time playing around with desktop applications (I have experience with iphone applications) and I'm stuck - My text view will not update to show any text:

.m:
@synthesize textView;

    NSString *txt = [[[NSString alloc] initWithData:responseData encoding: NSASCIIStringEncoding] autorelease];
    NSLog(@"txt = %@", txt);
    [textView setString:txt];

.h:
    IBOutlet NSTextView *textView;
}
@property(nonatomic, retain) IBOutlet NSTextView *textView;

And IB says textView -> Text View, so everything looks good:

• NSLog above outputs the contents of the url resource Im fetching

So, what am I missing?

Answer 1

Double check if the outlets are done in IB. That's probably the reason (textView is probably nil here).

Answer 2

Where is this setString code being called? It's possible the IB outlet isn't instantiated yet. You can check this with a simple

if (textView) {
    NSLog(@"textView is not nil);
} else {
    NSLog(@"textView is nil");
}

To be sure that everything is set up when you call this, make sure it's after 'awakeFromNib' is called in any objects created through IB.

See NSNibAwaking Protocal

Answer 3

Can you double check NSTextView properties like isEditable, textColor etc to make sure none of them are set incorrectly.

Other than that the code looks good.

Answer 4

我重新连接了IB中的所有内容，进行了保存，重建，并且可以正常工作... = [
