當我按Enter鍵時，我的NSTextField突出顯示文本。我只想「輸入」在該字段中放置「NewLine」字符，以便我可以繼續輸入

Question

我只是想「輸入」在字段中放置「NewLine」字符，以便我可以繼續輸入。 THX

- (void)someAction:(id)sender 
{ 
    NSString *s = [tf1 stringValue]; 
    [tf1 setStringValue:[NSString stringWithFormat:@"%@%@",s, @"\nEnter\n" ]]; 
} 

- (void)myRun:(NSButton*)btn 
{ 
    NSString *s = [tf1 stringValue]; 
    [tf1 setStringValue:[NSString stringWithFormat:@"%@%@",s, @"hello\nthere" ]]; 
} 


- (void)windowControllerDidLoadNib:(NSWindowController *)aController 
{ 
    [super windowControllerDidLoadNib:aController]; 
    // Add any code here that needs to be executed once the windowController has loaded the document's window. 

    //[aController.window setFrame:CGRectMake(10,10,1000,600) display:TRUE]; 
    [aController.window setFrame:NSMakeRect(10,10,1000,600) display:TRUE]; 
    [aController.window setBackgroundColor:[NSColor grayColor]]; 



    //NSButton *b1 = [[NSButton alloc] initWithFrame:CGRectMake(10, 530, 100, 30)]; 
    NSButton *b1 = [[NSButton alloc] initWithFrame:NSMakeRect(10, 530, 100, 30)]; 
    [b1 setTitle:@"Run"]; 
    [b1 setAction:@selector(myRun:)]; 
    [aController.window.contentView addSubview:b1]; 

    tf1 = [[NSTextField alloc] initWithFrame:NSMakeRect(10, 10, 600, 500)]; 
    [aController.window.contentView addSubview:tf1]; 
    [tf1 setTarget:self]; 
    [tf1 setAction:@selector(someAction:)]; 

}
