There is a reason why this method doesn't work?
-(void)textViewDidBeginEditing:(UITextView *)textView
{
textView.text = #"";
}
I just want that when I tap on UITextView, the text inside is canceled...
Thanks and have a nice day!
REPLACE:
OK. Here is what you need to do. First, in your class add the protocol:
#interface ClrssEditSearchVC : UITableViewController <UITextViewDelegate>
Then go into Interface Builder/Storyboard and Ctrl-drag from the UITextView to the source file and it will give you the option to create the event. Then add your code to the new method.
ADD:
Another thing with your current implementation. First, correction in terms. You are working with a UITextField (not UITextView). To get your original impl working:
First, be sure you you have added the protocol to your class.
#interface YourVC : UIViewController <UITextViewDelegate>
Second, in your viewDidLoad method, add the following:
self.myTextField.delegate = self;
Finally, your method sig needs to change to ("view" -> "field"):
-(void)textFieldDidBeginEditing:(UITextField *)textField

My EditView is:
//.addChild(
EditView::new().fixed_width(30).with_name("customer_names")
//)
Now when try set content:
siv.call_on_name("customer_names", |view: &mut EditView| {
view.set_content("helloooo");
});
Does nothing. :<
However, the textviews work well! 🙈
let view = siv.find_name::<TextView>("customer_id").unwrap();
view.set_content("this is ok helloo!!");
Thanks in advance!
I found the problem.
It didn't work because of the order of calling the functions. This is the creation of the editview:
EditView::new().fixed_width(30).with_name("customer_names") //no work
The search by name function was not finding the view. If I do so, if it finds the view:
EditView::new().with_name("customer_names").fixed_width(30) //this work ok!!
I have to put the with_name() first before other properties, otherwise it puts a wrapper on it and the editview doesn't work.
I am having a problem passing an object from a TableView to a ViewController in an IOS app. I am using storyboard and have elected ARC and passing the delegate in my "prepareForSegue" method.
Here is my code in my TableView which segues via a push to another ViewController:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NextViewController *vc = (NextViewController *)[segue destinationViewController];
vc.managedObjectContext = managedObjectContext;
if ([[segue identifier] isEqualToString:#"EditCategory"])
{
NSInteger selectedIndex = [[self.tableView indexPathForSelectedRow] row];
// I get a red warning which states "Cast of 'NSInteger' (aka 'int') to 'Entity' is disallowed with ARC" on this line:
[vc setEntity:(Entity *)selectedIndex];
}
}
Does anybody have any suggestions for how I can pass my object from the TableView to the ViewController? I am new to programming and have tried various expressions but nothing seems to work.
The error you're getting has to do with types.
The class NextViewController apparently has a method called -setEntity: that takes an object of type Entity *. The error is because you're trying to give -setEntity: an argument of the wrong type. You're trying to give it an NSInteger (which is a number like 0, 5, -999), but it wants an Entity.
You're on the right track for passing data from the table view to the NextViewController. You just need to do one of the following:
pass an Entity to -setEntity: (does the Entity class perhaps
have a constructor that takes an NSInteger?)
add a method to NextViewController that takes an NSInteger, and call that instead of -setEntity:
I am using UICsutomSwitch for my application. When I try to create it, I am getting an exception like,
Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSArray objectAtIndex:]: index 2 beyond bounds for empty array'
My code is as follows,
UICustomSwitch.h
#import <Foundation/Foundation.h>
#interface UICustomSwitch : UISwitch
{
}
-(void)setLeftLabelText:(NSString *)labelText;
-(void)setRightLabelText:(NSString *)labelText;
#end
UICustomSwich.m
#import "UICustomSwitch.h"
#implementation UICustomSwitch
-(UIView *)slider
{
return [[self subviews ] lastObject];
}
-(UIView *)textHolder
{
return [[[self slider] subviews]objectAtIndex:2];
}
-(UILabel *)leftLabel
{
return [[[self textHolder] subviews]objectAtIndex:0];
}
-(UILabel *)rightLabel
{
return [[[self textHolder] subviews]objectAtIndex:1];
}
-(void)setLeftLabelText:(NSString *)labelText;
{
[[self leftLabel] setText:labelText];
}
-(void)setRightLabelText:(NSString *)labelText
{
[[self rightLabel]setText:labelText];
}
#end
View Controller:
UICustomSwitch* switchView=[[[UICustomSwitch alloc]initWithFrame:CGRectMake(200,5,90,30)]autorelease];
[switchView setLeftLabelText:#"F"];
[switchView setRightLabelText:#"M"];
[switchView addTarget:self action:#selector(genderAction:) forControlEvents:UIControlEventValueChanged];
[elementView addSubview:switchView];
I am getting exception at " return [[[self slider] subviews]objectAtIndex:2];" call. I don't know what is the wrong, Can you guys please suggest me on this.
Thanks in advance,

I ran across this issue and found the answer here:Custom UISwitch Text
Basically in iOS 4, there were UILabel's in the UISwitch's subviews that represented the "On/Off" labels. In iOS 5, there are no UILabels in the subviews array (hence the array error you're getting). The above link offers an external class you can download and customize. In my opinion, it seems like Apple is discouraging customization of UISwitch. The functionality you're after could be accomplished another way (segmented control, simulated checkbox, etc).
Also, in the given link above, the author proposes that the issue might be with not including armv6. I tried this and it does not fix the problem.
The exception indicates you are attempting to access an element of the array that is out of bounds (in a place that is larger than the actual size of the array).
You can use breakpoints and/or NSLog() calls carefully placed in your code to determine if this array ever is not-empty, and if that is so, you can continue to use these calls to find out just where the array becomes empty.
Clearly if the array is empty then the switch is setup differently than you expect it to be.
I need to track changes in my UITextView method (actianly for limiting number of lines), but none of UITextViewDelegate methods are being called when editing in UITextView begins. Not even - (void)textViewDidChange:(UITextView *)textView;
I dont know what Im doing wrong
I added UITextViewDelegate method to header file like that:
#interface PirmasViewController : UIViewController <UITextViewDelegate, MFMa......
And I put any methods for tracking changes in my implementation file:
- (void)textViewDidChange:(UITextView *)textView{NSLog(#"something changed");}
- (BOOL)textView:(UITextView *)aTextView shouldChangeTextInRange:(NSRange)aRange replacementText:(NSString*)aText{
NSLog(#"something changed");
return YES;
}`
but no rezults.
I was missing one line of code:
UITextViewFieldName.delegate = self;
I am looking for help to achieve the following
The Diagram represents a car, users can add engine and colour
when I view the XML it looks like this:
<Car>
<Engine>BigEngine</Engine>
<Colour>Pink</Colour>
</Car>
What I would like to do is to wrap the car inside 'vehicle', i.e
<Vehicle>
<Car>
<Engine>BigEngine</Engine>
<Colour>Pink</Colour>
</Car>
</Vehicle>
I am not sure of the best way to achieve this. I want the model explorer and the generated XML to be wrapped in 'vehicle' but for all other intents and purposes the user is working with a car only
Info: Visual Studio 2010, C# and DSL SDK for 2010
I would try two different approaches:
1st: override DSL Package class DocData
In DocData.cs file and override method
protected override void OnDocumentSaved(System.EventArgs e)
and then I would create the wrapper
afterwards I'd override in DocData.cs
protected override void OnDocumentLoading(System.EventArgs e)
and before calling the base method base.OnDocumentLoading(e); i would delete from the file.
2nd: Under DSL Explorer go to XML Serialization Behaviour and set Car Domain Class "Is Custom = true".
This solution is not straightforward but it's not as complicated as it seems at the first place. You'll must define every single method but for each custom method you can call a DSL generated method called "DefaulMethod" which has the default DSL serializer behaviour.
I am currently using VS 2005, so some things might have changed...
I have fixed this by the following. I am double deriving the Car class and in the Car serializer I am doing this:
Writing the extra elements:
public partial class CarSerializer : CarSerializerBase
{
public override void Write(SerializationContext serializationContext, ModelElement element, XmlWriter writer, RootElementSettings rootElementSettings)
{
// Adds the Model and LobSystem root elements to match that required by the SharePoint BCS
writer.WriteStartElement("Garage");
writer.WriteStartElement("Cars");
base.Write(serializationContext, element, writer, rootElementSettings);
writer.WriteEndElement();
writer.WriteEndElement();
}
}
To be able to read this back in I am overriding the Car LoadModel method in the SerializationHelper and where it is getting the reader I am reading the elements until I get to Car.
....
XmlReader reader = XmlReader.Create(fileStream, settings);
reader.MoveToContent();
while (!reader.EOF && !reader.Name.Equals("Car"))
{
reader.Read();
}
reader = reader.ReadSubtree();
// using (global::System.Xml.XmlReader reader = global::System.Xml.XmlReader.Create(fileStream, settings))
using (reader)
{
....
