This used to work in iOS 3.0, but I know some things have changed since then. Could someone point me in the correct direction to get this fixed? Here is my current code.
Code:
#import "Blank_FillerViewController.h"
#import <QuartzCore/QuartzCore.h>
@implementation Blank_FillerViewController
@synthesize scroll;
@synthesize textField;
@synthesize textFeild;
@synthesize scrollView;
#define kOFFSET_FOR_KEYBOARD 185.0
- (void)keyboardWasShown:(NSNotification*)aNotification {
if (keyboardShown) return;
NSDictionary* info = [aNotification userInfo];
// Get the size of the keyboard.
NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
// Resize the scroll view (which is the root view of the window)
CGRect viewFrame = [scrollView frame];
viewFrame.size.height -= keyboardSize.height;
scrollView.frame = viewFrame;
// Scroll the active text field into view.
CGRect textFieldRect = [activeField frame];
[scrollView scrollRectToVisible:textFieldRect animated:YES];
keyboardShown = YES;
}
- (void)keyboardWasHidden:(NSNotification*)aNotification {
NSDictionary* info = [aNotification userInfo];
// Get the size of the keyboard.
NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
// Reset the height of the scroll view to its original value
CGRect viewFrame = [scrollView frame];
viewFrame.size.height += keyboardSize.height;
[scrollView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];
scrollView.frame = viewFrame;
keyboardShown = NO;
}
- (void)touchesEnded: (NSSet *)touches withEvent: (UIEvent *)event {
for (UIView* view in self.view.subviews) {
if ([view isKindOfClass:[UITextField class]])
[view resignFirstResponder];
}
}
- (BOOL)textFieldShouldReturn: (UITextField *)textField {
[textField resignFirstResponder];
return YES;
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
sleep(3);
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(keyboardWasShown:)
name: UIKeyboardDidShowNotification
object: nil];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(keyboardWasHidden:)
name: UIKeyboardDidHideNotification
object: nil];
keyboardShown = NO; // 1
[scrollView setContentSize: CGSizeMake( 320, 480)]; // 2
scrollView.maximumZoomScale = 4.0;
scrollView.minimumZoomScale = 0.75;
scrollView.clipsToBounds = YES;
scrollView.delegate = self;
[scrollView addSubview:imageview];
}
- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
return imageview;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
activeField = textField;
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
activeField = nil;
}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (YES);
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
