Re: iPhone: UIWebView not displaying until scrolled?
Hi Eric,
can you post how your web view is animated?
If I setup quick test case:
@implementation WebViewController
@synthesize webView;
- (void)viewDidLoad
{
[super viewDidLoad];
self.webView.delegate = self;
NSString *path = [[NSBundle mainBundle] pathForResource:@index
ofType:@html];
NSURL *url = [[NSURL alloc] initFileURLWithPath:path];
[self.webView loadRequest:[NSURLRequest requestWithURL:url]];
self.webView.alpha = 0.0;
[url release]; url = nil;
}
- (void)viewDidUnload
{
self.webView = nil;
}
- (void)dealloc
{
[webView release]; webView = nil;
[super dealloc];
}
-(void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString *loadHandlerStr = @window.pageLoaded();
[self.webView stringByEvaluatingJavaScriptFromString:loadHandlerStr];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
self.webView.alpha = 1.0;
[UIView commitAnimations];
}
@end
both UIWebView is animated (and visible) and also content within html
web page is drawn (and animated):
(JavaScript/CSS)
from opacity 0.0:
-webkit-transition: opacity 2s linear;
to 1.0:
elem.style.opacity = 1.0;
maybe that is some different issue that somehow became apparent on
your web view use,

Hello, all ...
I've a question about the UINavigationController backBarButtonItem property.
I wanted to merely set my own image for the back button, instead of it using
the title of the controller above in the hierarchy. So, this is what I did
(yes this app is using Three20, but I don't think that's the reason):
- (id)initWithNavigatorURL:(NSURL *)URL query:(NSDictionary *)query
{
if (self = [super initWithNavigatorURL:URL query:query])
{
self.navigationItem.backBarButtonItem = [[[UIBarButtonItem
alloc] initWithImage:[UIImage imageNamed:@backarrow.png]
style:UIBarButtonItemStylePlain target:self action:@selector(back)]
autorelease];
}
return self;
}
- (void)back:(id)sender
{
}
Now, this worked -- but I wasn't _expecting_ it to work. I was expecting that
my back selector would be called, and I would have to tell the nav
controller to pop. However, my back selector isn't called, and the back
button _works_ like it always has. While i'm not in any way against freebees
like this, i'm a bit concerned as to _why_ it works like this. Any
explanation would be appreciated, explanations that actually edify me more so
:-)

John

Hello,
I have the following issue:
There is a label nameLabel which text needs to be set from a certain field
in the dictionary. I don't want to set the label's text property directly in
the main thread's method - instead I use an NSString instance called name
to store the text. This is an ivar, see property declaration below.
Before the thread is finished and returns, it schedules the method
-upadateLabels on the main thread which finally sets the label's text
property (shown below).
- (void) updateLabels
{
self.nameLabel.text = self.name;
}
One *important* observations is here:
Before generating the URL request, I actually need a parameter which is asked
from the user via an interface.
When the user starts to edit the input (a UITextField) the view controller
gets notified through a method, shown below.
The purpose of this method is to clear the previous results.
** IFF I do not set the text property to nil, the NSString instance name
remains valid. So, it seems, that the string object will be *shared* - but
not copied. Hence the auto release pool does not dealloc the string. The
label's text property is declared as: @property(nonatomic, copy) NSString*
text
This looks strange to me. Any thoughts?
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
// User entered editing: clear labels:
self.nameLabel = nil; // if uncommented, the ivar name remains valid
}

Re: [iPhone] Why can't a UITextField be its own delegate?
Hi WT,
have you tried - to avoid everything discussed in thread - to use

proper avoiding discussed issues and at the same time it hides
everything into your subclass (wrapped delegate class details are
hidden into module):

@implementation CustomTextFieldDelegate
-(BOOL)textField:(UITextField*)text_field
shouldChangeCharactersInRange: (NSRange) range replacementString:
(NSString*) string
{
NSLog(@-textField: shouldChangeCharactersInRange: replacementString:);
return YES;
}
-(BOOL)textFieldShouldBeginEditing:(UITextField*)text_field
{
NSLog(@-textFieldShouldBeginEditing:);
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField*)text_field
{

{

}
@end

{
_customDelegate = [[CustomTextFieldDelegate alloc] init];
self.delegate = _customDelegate;

Hello all,
I need to create a subclass of UITextField for a text field that performs
some control over its own editing. The obvious idea is to make the subclass
instance set itself up as its own delegate, but that freezes the app as soon
as the delegate method -textFieldDidBeginEditing returns.
Looking at Activity Monitor, the CPU usage of the app goes up to nearly 100%.
I've since created the most trivial app with a UITextField subclass that
conforms to the UITextFieldDelegate protocol and which sets itself up as its
own delegate and, sure enough, the app freezes.
Here's the subclass. Set up a project then add a text field to a view and
make its class be CustomTextField. Compile and run, and watch it freeze when
you attempt to edit the text in the field.
So... why can't the field be its own delegate?
Thanks in advance.

Hi,
i'm trying to execute a javascript function on the iPhone and get
the return value.
The function is simple:
return hello;
I'm using a UIWebView and the -
stringByEvaluatingJavaScriptFromString: method but, while it works
on os x, it doesn't on the iPhone.

Re: -stringByEvaluatingJavaScriptFromString: return value iphone
hi Marco,
I'm not John Resig (http://ejohn.org/) but I would not assume that
return o will actually evaluate to javascript object/function call,
I would rather script:
NSString *scriptCode = @\Hello\;
or:
NSString *scriptCode = @(function(){return \hello\;})();;
but I would also fire up Safari (WebKit) script console (ALT+CMD+C)
and take few trials with code.
Because you're correct of differencies between UIWebView and WebView
(@return \hello\ works in WebView) I would look into other place
(webkitsk-dev list). Maybe that is because WebKit on OS X is bridged
JavaScriptObjective-C while on Touch OS is not (return o does not
work in WebKit/Safari interactive console while it works in WebView
string code evaluating call).
regards,
Peter

Re: release static pointers
hi Christian,

I'm wondering if and how
the pointer to the statement will be released. In the code samples I
saw there is no trace of the releasing (in this case,
sqlite3_finalize(statement)).
This is the example:
http://icodeblog.com/wp-content/uploads/2008/08/9-todom.png
It looks like you started in wrong place. The sample code is certainly
based on official Apple's sqlite integration sample:
http://developer.apple.com/iphone/library/samplecode/SQLiteBooks/
(go there, registration for online type of ADC account is free),
which is far more better place to start I think. To finalize
statements there is dedicated class method defined in entity class
that gets called when application is to be closed (in blog sample that
could be implemented as:
@interface ...
+(void)finalizeStatements;
@implementation
+(void)finalizeStatements
{
if(stmt){
sqlite3_finalize(stmt);
stmt = NULL;
};
}
called as:
[Todo finalizeStatements]
from one of controllers.

Peter
