以编程方式添加uiscrollview

Question

I am trying to add a UIScrollView to the following code but a little unsure as it contains content from a txt file. Would appreciate some help on this. Thanks :)

#import "AboutController.h"


@implementation AboutController

- (NSString *)textForView 
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"txt"];
    NSError *error;
    return [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];
}

#pragma mark - View lifecycle

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
    [super viewDidLoad];
    [self showLogoInNavBar:YES];
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

In your:

- (void)loadView
{
     CGRect scrollViewFrame = CGRectMake(0, 0, 320, 460);
     UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollViewFrame];
     [self.view addSubview:scrollView];
     CGSize scrollViewContentSize = CGSizeMake(640, 460);
     [scrollView setContentSize:scrollViewContentSize];
}

Hope that helps!!
