Change text on swipe - ios

Question

I am creating a text jokes app what i need is i want the UITextView in swipe form like when i swipe the first joke after a gap another UITextview comes in with another joke , so far what i have done is i have manually created the UITextView ( like if there is 10 jokes then 10 uitextview ) and added them in a scroll but that is taking too much time in viewdidload method and the app takes 6,7 second to load ...
if you have anyother idea please do let me know
for (int i = 0; i < arrresult.count; i++) {
CGRect frame;
frame.origin.x = self.scrollmain.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.scrollmain.frame.size;
// UITextView *subview = [[UITextView alloc] initWithFrame:CGRectMake((frame.origin.x)+40,(frame.origin.y)+10, 230, 120)];
// UITextView *subview2 = [[UITextView alloc]initWithFrame:CGRectMake((frame.origin.x)+40,(frame.origin.y)+160,230, 120)];
UITextView *subview = [[UITextView alloc] initWithFrame:CGRectMake((frame.origin.x)+40,(frame.origin.y)+10, 230, 120)];
UITextView *subview2 = [[UITextView alloc]initWithFrame:CGRectMake((frame.origin.x)+40,(frame.origin.y)+160,230, 120)];
subview.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"BG_text.png"]];
subview2.backgroundColor = [UIColor whiteColor];
[subview setFont:[UIFont boldSystemFontOfSize:14]];
[subview2 setFont:[UIFont boldSystemFontOfSize:14]];
subview.layer.cornerRadius = 10 ;
subview2.layer.cornerRadius = 10;
NSString *p = [duaobj2 dua_arabic];
NSString *b = [duaobj2 eng_trans];
subview.text = p;
subview2.text = b;
[self.scrollmain addSubview:subview];
[self.scrollmain addSubview:subview2];
subview.editable = NO;
subview2.editable = NO;
subview.textColor = [UIColor blackColor];
subview2.textColor = [UIColor blackColor];
subview.backgroundColor = [UIColor whiteColor];
subview2.backgroundColor = [UIColor whiteColor];
scrollmain.showsHorizontalScrollIndicator = NO;
CGRect frame1 = subview.frame;
CGRect frame2 = subview2.frame;
frame1.size.height = subview.contentSize.height;
frame2.size.height = subview2.contentSize.height;
subview.frame = frame1;
subview2.frame = frame2;
}
self.scrollmain.contentSize = CGSizeMake(self.scrollmain.frame.size.width * arrresult.count,self.scrollmain.frame.size.height);
scrollmain.pagingEnabled = TRUE;
scrollmain.delegate = self;

There is no need to load the subviews at the time of viewDidLoad.
You should delay this by using scrollView delegate methods.
You should create only 3 textviews at max. Current, previous and next.
On scrollViewDidScroll delegate method, you should wisely remove previously loaded textview and you should add new textview.
