Problem in getting Navigation Bar using JSQMessagesViewController, I have tried getting Navigation Bar in my project, but failed to get it. Please let me know what the methods need to be added to get it.

I try to calculate the size of a UIWebView with a given content, but without showing the view. I only need to know the size.
My Problem: When I execute the code, the delegate of the UIWebView isn't called. Why?

#import < Foundation/Foundation.h>
#class Message;
#interface MessageSizeCaluclator : NSObject <UIWebViewDelegate>

#synthesize message = _message;
#synthesize webView = _webView;

{
self = [super init];
if (self) {
_message = message;
// WebView
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_webView.delegate = self;
}
return self;
}
- (void)saveSize
{
NSLog(#"%s message = %#", __PRETTY_FUNCTION__, _message.text);
[_webView loadHTMLString:[NSString stringWithFormat:#"<div style='font-family:Helvetica;font-size:13px;'>This is a test</div>", _message.text]
baseURL:nil];
}

{
NSLog(#"%s", __PRETTY_FUNCTION__);
}
- (void)webViewDidFinishLoad:(UIWebView *)webView

}
#end
Implementation
MessageSizeCaluclator* messageSizeCalculator = [[MessageSizeCaluclator alloc] initWithMessage:message];
[messageSizeCalculator saveSize];
Add your UIWebView to some UIView, make its frame offscreen (so users can't see it). The delegate methods won't be called if UIWebView is not in the view hierarchy of the app.
The issue is that my UITextField wrapper class isn't getting the UITextField to appear within a UITableViewCell (however, a regular UITextField view works just fine):
Here is my custom UITextField:
Header:
#import <UIKit/UIKit.h>
#protocol TUTextFieldDelegate <NSObject>
- (BOOL)textField:(UITextField *)textField
shouldChangeCharactersInRange:(NSRange)range
replacementString:(NSString *)string;
- (BOOL)textFieldShouldClear:(UITextField *)textField;

#end
Implementation:
#import "TUTextField.h"
#interface TUTextField ()
#property (nonatomic, strong) UITextField *textField;
#end
#implementation TUTextField
- (id)initWithTextField:(UITextField *)textField
{
self = [super initWithFrame:textField.frame];
if (self) {
self.textField = textField;
_textField.delegate = self;
_fixedDecimalPoint = NO;
}
return self;
}
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.textField = [[UITextField alloc] initWithFrame:frame];
_textField.delegate = self;
[self addSubview:_textField];
_fixedDecimalPoint = NO;
}
return self;
}
- (void)setKeyboardType:(UIKeyboardType)keyboardType {
_textField.keyboardType = keyboardType;
}
- (void)setPlaceholder:(NSString *)placeholder {
_textField.placeholder = placeholder;
}
- (void)setBorderStyle:(UITextBorderStyle)borderStyle {
_textField.borderStyle = borderStyle;
}
-(void)setAdjustsFontSizeToFitWidth:(BOOL)adjustsFontSizeToFitWidth {
_textField.adjustsFontSizeToFitWidth = adjustsFontSizeToFitWidth;
}
-(void)setClearButtonMode:(UITextFieldViewMode)clearButtonMode {
_textField.clearButtonMode = clearButtonMode;
}
-(void)setText:(NSString *)text {
_textField.text = text;
}
/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
[self addSubview:self.textField];
}
*/
- (void)viewDidLoad {
[self addSubview:_textField];
}
- (void)viewWillAppear {
[self addSubview:_textField];
}
- (BOOL)textField:(UITextField *)textField
shouldChangeCharactersInRange:(NSRange)range
replacementString:(NSString *)string
{
if ([_delegate respondsToSelector:#selector(textField:shouldChangeCharactersInRange:replacementString:)]) {
return [_delegate textField:textField shouldChangeCharactersInRange:range
replacementString:string];
}
return YES;
}
- (BOOL)textFieldShouldClear:(UITextField *)textField {
if ([_delegate respondsToSelector:#selector(textFieldShouldClear:)]) {
return [_delegate textFieldShouldClear:textField];
}
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField {
if ([_delegate respondsToSelector:#selector(textFieldDidBeginEditing:)]) {
[_delegate textFieldDidBeginEditing:textField];
}
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
if ([_delegate respondsToSelector:#selector(textFieldDidEndEditing:)]) {
[_delegate textFieldDidEndEditing:textField];
}
}
#end
And here is the code to add my custom wrapper to the table view:
} else if (indexPath.row == 1) {
cell.textLabel.text = #"Tax Rate";
if (!_textField) {
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(220.0, 8.0, 60.0, 26.0)];
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.adjustsFontSizeToFitWidth = YES;
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.keyboardType = UIKeyboardTypeDecimalPad;
textField.placeholder = kTaxRateDefault;
_textField = [[TUTextField alloc] initWithTextField:textField];
_textField.delegate = self;
// retrieve saved settings
_taxRate = [[SettingsSingleton sharedManager] taxRate];
if (![_taxRate isEqualToString:#""])
_textField.text = _taxRate;
}
UILabel *percentSign = [[UILabel alloc] initWithFrame:CGRectMake(285.0, 6.0, 20.0, 26.0)];
percentSign.text = #"%";
percentSign.backgroundColor = [UIColor clearColor];
[cell addSubview:_textField];
[cell addSubview:percentSign];
}
}
Any help appreciated!
I don't think this is the best way to extend a UITextField.
Instead of making an NSObject with a UITextField under it you should be saying something like:
Interface:
#interface UITextField (extendedUITextField) {
// Variables
}
//Methods
#end
Implementation:
#implementation UITextField (extendedUITextField)
// Method implement
#end
Hope this helps.
I have a simple utility app, with a MainViewController.m & h and a FlipsideViewController.m & h. Within my storyboard I have a button on MainViewController. I want to be able to click the button and run a method in FlipsideViewController.m is this possible? this is my first app and I am a total novice. all comments / suggestion welcome.
enter code here
i have this in my FlipsideViewController.m this is what i want to call when i click the button.
- (void)SaveFPQData

You have mainly two ways:
add a property (eg. self.flipSideController) to your MainViewController to store a reference to the FlipsideViewController; then call SaveFPQData though it (eg. [self.flipSideController SaveFPQData]; or
use notification center to post a notification from saveButton: that triggers SaveFPQData; this would go like this:
//-- in flipsidecontroller `viewDidLoad`:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(SaveFPQData)
name:#"SaveFPQData"
object:nil];
//-- in saveButton:
[[NSNotificationCenter defaultCenter] postNotificationName:#"SaveFPQData" object:nil];
The second method is the simplest to implement, IMO, and it allows for the loosest coupling, at the expense of some clock cycles.
EDIT:
It is not entirely clear to me what you are trying to do (specifically, I don't understand fully how you can push the button in MainViewController once you FlipsideViewController is displayed; on the other hand, if you do not segue to the FlipsideViewController, then it is not there, so you cannot send a message to it), anyway you could try and initialise your self.flipsideViewController property in prepareForSegue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"showAlternate"]) {
UIViewController* controller = [segue destinationViewController];
[controller setDelegate:self];
if ([controller isKindOfClass:[FlipsideViewController class]])
self.flipsideViewController = (id)controller;
}
}
after doing that, your MainViewController will be able to send the saveFPQ message to the FlipsideViewController.
If you mean you would like to send the saveFPQ message before segue-ing to the FlipsideViewController, you should make the saveButton segue to it and the call the saveFPQ method.
What I suspect is you need some kind of "model" object accessible both from the main view and the flipside view controller.
Hope this helps.
my problem - I want to pass information from the TableView in DetailView, but somewhere in the self.detailViewController.detailItem no value is passed.
that is:
self.detailViewController.detailItem =#"123";

NSLog(#"%#", sss);
In NSLog output (null)
Here is my source code:

In what may be the problem and how to fix it?
P.S. Sorry for my english, I'm just learning))
Since you are using a storyboard, you should be opening the detail controller on a segue.
Look up the segue identifier (say, it's OpenDetail) in the story board, then add the following code to your initial controller:
-(void)prepareForSegue:(UIStoryboardPopoverSegue*)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"OpenDetail"]) {
DetailViewController *dest = segue.destinationViewController;
dest.detailItem =#"123";
}
}
