I have been working on this for a long time.
I need to expand and collapse the UILabel text on click of a button located at the end of text of UILabel.
Thinks I have tried
I have use VSWordDetector to detect which word of UILabel get tapped but it not gave correct word tapped.
I suggest you just use UIButton without visible frame with titleLabel.text #"..." or #"▼".
So, for example, you have a string #"Some long long, really long string which couldn't be presented in one line". Then take a substring for UILabel text, and put a button described above on the right from your label. Add an action for ▼-buuton to update label.text and hide button.
Code snippet:
#interface YourClass
#property (strong, nonatomic) UILabel* longStringLabel;
#property (strong, nonatomic) UIButton* moreButton;
#property (strong, nonatomic) NSString* text;
#end
#implementation YourClass
// Some method, where you add subviews, for example viewDidLoad
{
// ...
self.longStringLabel.frame = CGRectMake(0, 0, 100, 44);
[self addSubview:self.longStringLabel];
self.moreButton.frame = CGRectMake(CGRectGetMaxX(self.longStringLabel.frame), 0, 20, 44);
[self addSubview:self.moreButton];
// ...
}
- (UILabel*)longStringLabel
{
if (!_longStringLabel)
{
_longStringLabel = [UILabel new];
_longStringLabel.lineBreakMode = NSLineBreakByTruncatingTail;
}
return _longStringLabel;
}
- (UIButton*)moreButton
{
if (!_moreButton)
{
_moreButton = [UIButton buttonWithType:UIButtonTypeCustom];
_moreButton.titleLabel.text = #"▼";
[_moreButton addTarget:self action:#selector(moreButtonDidTap:) forControlEvents:UIControlEventTouchUpInside];
}
return _moreButton;
}
- (void)moreButtonDidTap:(UIButton*)sender
{
self.longStringLabel.frame = [self.text boundingRectWithSize:CGSizeMake(self.longStringLabel.frame.size.width + self.moreButton.frame.size.width, 100)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{ NSFontAttributeName : self.longStringLabel.font }
context:nil];
self.longStringLabel.text = self.text;
self.moreButton.hidden = YES;
}

I am new in iOS and I am facing problem regarding to get the value from custom table view cell to view controller. I am using rate view for rating and I am checking if value of rate is less then 3 then it show have to enter text in the text view and I want to get value in view controller
My code is like this

How can I get label and textview value in viewcontroller and I want to set rate view value to rate view after reload table.
Hear in the Image i am getting five star and If I click on less then 3 star it should have to write comment.I am taking rate value in the label.How can I get both label and textvalue in view controller.Please tell me to update question if you want more data.Thanks in Advance!
So write this in your CustomTableViewCell.h
#property(nonatomic,assign)NSInteger selectedRating;
everytime when the rating is updated in the Cell, you have to change the value of this variable.
In the viewController it depends on when you want to get the value of this cell. For example in this method:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
CustomTableViewCell *yourCell = (CustomerTableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
NSLog(#"%lu",yourCell.selectedRating);
}
Let me know if this was helpful!
Another way without a variable is to read the NSString in the statusLabel and change the string to a NSInteger variable...
If you are using your delegate...
Then implement the delegate RateViewDelegatein the viewController. The delegate is called in the class to which it is assigned...
Try this
You have to add the #property (nonatomic, weak) NSObject<RateViewDelegate>* delegate;
to the header file of your CustomTableViewCell.h in the method
-(UITableViewCell) cellForRowAtIndexPath....
you have to assign the delegate like this
cell.delegate = self;
Now modify your cell delegate method to this
- (void)rateView:(RateView *)rateView ratingDidChange:(int)rating {
self.statusLabel.text = [NSString stringWithFormat:#"%d", rating];
NSLog(#"Rating value =%#",self.statusLabel.text);
StatusValue=statusLabel.text;
NSLog(#"Status Value String =%#",StatusValue);
// Hear I am getting value of rating..in StatusValue..
int status=[StatusValue intValue];
if(status<=3)
{
commenttxtview.hidden=NO;
}
else{
commenttxtview.hidden=YES;
}
if([self.delegate respondsToSelector:#selector(rateView:ratingDidChange:)]){
[self.delegate rateView:rateView ratingDidChange:rating];
}
}
I'm writing a custom UIView class that has its own sub UIView. I want this UIView to be centered inside the superView with two UIButtons inside of it, two UILabels.
I overwrite my init with the parameters I want in the custom UIView and in that init method in implementation, I am alloc/initializing all my objects and at the end of my init method, I add my subView to self. And I add all the buttons and objects to the subView.
The problem is, even after setting my coordinates and frames in layoutSubviews, my buttons and labels do not appear in the subView.
Here's my method code:
#property (nonatomic, weak) UIView *alertSubView; // this will be the message view in middle of screen
#property (nonatomic, weak) UILabel *alertTitleLabel; // This will be the title within the alertSubView
#property (nonatomic, weak) UILabel *alertMessageLabel; // This will be the alert message under the alert title
#property (nonatomic, weak) UIButton *doNotAskButton; // This will be the do not ask button
#property (nonatomic, weak) UIButton *cancelButton; // This will be the cancel button, bottom left of alertView
#property (nonatomic, weak) UIButton *confirmButton; // This will be the confirm button, bottom right of alertView
#property (nonatomic) BOOL doNotAsk;
#end
#implementation MyAlertView
- (instancetype)initWithFrame:(CGRect)frame messageTitle:(NSString *)title messageSubject:(NSString *)subject shouldAskForDoNotAsk:(BOOL)doNotAsk delegate:(id<MyAlertViewDelegate>)delegate
{
if (self = [super initWithFrame:frame]) {
self.delegate = delegate;
UILabel *alertLabel = [[UILabel alloc] init];
alertLabel.text = title;
alertLabel.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:15];
self.alertTitleLabel = alertLabel;
UILabel *messageLabel = [[UILabel alloc] init];
messageLabel.text = subject;
alertLabel.font = [UIFont fontWithName:#"HelveticaNeue-Light" size:15];
self.alertMessageLabel = messageLabel;
self.backgroundColor = [UIColor colorWithRed:170.0f/255.0f green:170.0f/255.0f blue:170.0f/255.0f alpha:0.75];
UIView *alertBoxView = [[UIView alloc] init];
self.alertSubView = alertBoxView;
[self.alertSubView addSubview:self.alertTitleLabel];
[self.alertSubView addSubview:self.alertMessageLabel];
if (doNotAsk) {
UIButton *buttonDoNotAsk = [[UIButton alloc] init];
buttonDoNotAsk.titleLabel.text = #"Do not ask me again";
self.doNotAskButton = buttonDoNotAsk;
[self.alertSubView addSubview:self.doNotAskButton];
}
UIButton *cancelButton = [[UIButton alloc] init];
cancelButton.titleLabel.text = #"Cancel";
cancelButton.titleLabel.textColor = [UIColor blueColor];
cancelButton.backgroundColor = [UIColor whiteColor];
cancelButton.opaque = YES;
self.cancelButton = cancelButton;
[self.alertSubView addSubview:self.cancelButton];
UIButton *confirmButton = [[UIButton alloc] init];
confirmButton.titleLabel.text = #"OK";
self.confirmButton = confirmButton;
[self.alertSubView addSubview:self.confirmButton];
self.alertSubView.backgroundColor = [UIColor whiteColor];
[self addSubview:self.alertSubView];
}
return self;
}
- (void)layoutSubviews
{
// place the alertView in the center of self view
CGFloat alertHeight = kAlertHeightModifier * self.frame.size.height;
CGFloat alertWidth = kAlertWidthModifier * self.frame.size.width;
[self.alertSubView setFrame:CGRectMake(0, 0, alertWidth, alertHeight)];
[self.alertSubView addSubview:self.cancelButton];
[self setUpButtonsAndLabels];
[self.alertSubView setCenter:self.center];
}
- (void) setUpButtonsAndLabels {
CGFloat alertHeight = kAlertHeightModifier * self.frame.size.height;
CGFloat alertWidth = kAlertWidthModifier * self.frame.size.width;
CGFloat buttonWidth = 0.5 * alertWidth;
CGFloat buttonHeight = 0.2 * alertHeight;
[self.cancelButton setFrame:CGRectMake(15, 45, buttonWidth, buttonHeight)];
[self.confirmButton setFrame:CGRectMake(0, 0, buttonWidth, buttonHeight)];
[self.confirmButton setCenter:self.center];
}
Try replacing your - (void)layoutSubviews with this .
- (void)layoutSubviews
{
// place the alertView in the center of self view
CGFloat alertHeight = kAlertHeightModifier * self.frame.size.height;
CGFloat alertWidth = kAlertWidthModifier * self.frame.size.width;
[self.alertSubView setFrame:CGRectMake(0, 0, alertWidth, alertHeight)];
[self.alertSubView addSubview:self.cancelButton];
[self setUpButtonsAndLabels];
[self.alertSubView setCenter:self.center];
[super layoutSubviews];
}
Or else initialize the button in viewdidload .It will work .
Try doing it in viewDidLoad. Should help to eliminate the problem, because the view will be fully initialized and ready to use.
I would like to start by saying that I am fairly new to iOS programming, so excuse my ignorance.
I have three UITextFields in my CustomLayout. I am asking users to fill in their name, age and sex. I would like two things, if possible. First I would like, as soon as a user hits the return button from the keyboard, the input string to be stored in an NSArray. In addition, the secondary objective is to iterate through the UITextFields when the user hits the same button.
// CustomLayout.h
#interface CustomLayout : UIView {
UITextField *nameField;
UITextField *ageField;
UITextField *sexField;
UILabel *nameLabel;
UILabel *ageLabel;
UILabel *sexLabel;
UIButton *startButton;
}
#property (nonatomic, strong) UITextField *nameField;
#property (nonatomic, strong) UITextField *ageField;
#property (nonatomic, strong) UITextField *sexField;
#property (nonatomic, strong) UILabel *nameLabel;
#property (nonatomic, strong) UILabel *ageLabel;
#property (nonatomic, strong) UILabel *sexLabel;
#property (nonatomic, strong) UIButton *startButton;
-(void)textFieldShouldReturn:(UITextField*)textField;
#end
In the implementation file
//CustomLayout.m
#implementation CustomLayout
#synthesize nameField, ageField, sexField;
#synthesize nameLabel, ageLabel, sexLabel;
#synthesize startButton;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self setBackgroundColor:[tkStyle viewBackgroundColor]];
NSString *startButtonLabel = #"Start Experiment";
//alocate and position views
CGRect viewRect;//placeholder rect, reused for each view
//nameLabel and nameField
nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(120, 95, 150, 40)];
nameLabel.textColor = [UIColor colorWithRed:106/256.0 green:180/256.0 blue:150/256.0 alpha:1.0];
nameLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:25];
nameLabel.backgroundColor=[tkStyle viewBackgroundColor];
nameLabel.text=#"Enter Name:";
nameField = [[UITextField alloc] initWithFrame:CGRectMake(280, 90, 200, 40)];
nameField.textColor = [UIColor colorWithRed:0/256.0 green:84/256.0 blue:129/256.0 alpha:1.0];
nameField.font = [UIFont fontWithName:#"Helvetica-Bold" size:25];
nameField.borderStyle = UITextBorderStyleRoundedRect;
nameField.backgroundColor=[tkStyle viewBackgroundColor];
textFieldShouldReturn:nameField.text;
// same for ageField and sexField
//startButton
viewRect = CGRectMake(250, sexField.frame.origin.y+75, 200, 40);
startButton = [[UIButton alloc] initWithFrame:viewRect];
[startButton setTitle:startButtonLabel forState:UIControlStateNormal];
[startButton setTitleEdgeInsets:UIEdgeInsetsMake(4, 0, 0, 0)];
[startButton setButtonIsActive:true];
//[startButton setOSCAddress:OSCStopPressedString];
[startButton addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchDown];
//and so on adjust your view size according to your needs
[self addSubview:nameField];
[self addSubview:ageField];
[self addSubview:sexField];
[self addSubview:nameLabel];
[self addSubview:ageLabel];
[self addSubview:sexLabel];
[self addSubview:startButton];
}
return self;
}
// that should allow for users to hit 'return' button to move through textfields
-(void)textFieldShouldReturn:(UITextField*)textField;
{
//[(NSArray *) userInfoArray addObject:textField.text];
}
// that should change Views as soon as the user presses 'Start Experiment'
-(void)buttonAction:(id)sender
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"startTest" object:self];
}
#end
Any help would be appreciated.
NSDictionary will be a good approach. you can have unique key for each textfield value.
-(void)textFieldShouldReturn:(UITextField*)textField;
should be:
- (BOOL)textFieldShouldReturn:(UITextField*)textField;
Also, don't forget to return TRUE or FALSE (or YES or NO).
To make this work, implement the UITextFieldDelegate protocol in your class.
Put the following line of code in your .m file, above the #implementation:
#interface CustomLayout () <UITextFieldDelegate>
#end
then, set the delegate in your UITextFields with:
nameField.delegate = self;
ageField.delegate = self;
sexField.delegate = self;
This way the textFieldShouldReturn: method will be called when the user presses 'enter'
A couple of things:
Given your delegate methods, I assume you've actually specified the delegate for your three UITextField controls to be the object in which you've implemented these various delegate methods.
If you want to control the behavior of the return key, implement the textFieldShouldReturn method:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
if (textField == self.nameField) {
[self.ageField becomeFirstResponder];
} else if (textField == self.ageField) {
[self.sexField becomeFirstResponder];
} else if (textField == self.sexField) {
[textField resignFirstResponder];
[self saveResults];
}
return NO;
}
I'd generally be inclined to do something like the above, where pressing return takes me to the next field, and pressing return on the last one dismisses the keyboard and tries to save the results.
BTW, in IB, I'd make sure that the "return key" setting for the first two control would be "Next", and for the last one, either "Go" or "Done".
Your save routine would simply populate an object with the contents of the three controls:
- (void)saveResults
{
Person *person = [[Person alloc] init];
person.name = self.nameField.text;
if (self.ageField.text) {
person.age = #([self.ageField.text integerValue]);
}
person.sex = self.sexField.text;
// now do whatever you want with this object
}
This obviously assumes that you have a Person class:
#interface Person : NSObject
#property (nonatomic, copy) NSString *name;
#property (nonatomic, strong) NSNumber *age;
#property (nonatomic, copy) NSString *sex;
#end
#implementation Person
#end
If you'd rather use a NSDictionary or NSArray, that's fine, too (make sure you check the text fields are not nil, though), though I personally prefer a well-defined model object like above.
As a refinement, you might want to make sure you only enter numeric values for age (if that's how you want to store the age):
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
if (textField == self.ageField) {
NSCharacterSet *invalid = [[NSCharacterSet characterSetWithCharactersInString:#"1234567890"] invertedSet];
NSRange range = [string rangeOfCharacterFromSet:invalid];
return range.location == NSNotFound; // if non-numeric character not found, return true
}
return YES;
}
I've got a couple of UIButtons with all the same style, but sometimes they have different colors and sometimes they have different widths. However, I hate to make a seperate class for a new button that just needs a slightly different color, so I thought that there must be a way to style a button and take, for instance, the color and height as a property. After that I image it would work just as importing a UITableView's datasource/delegate.
So a more concrete question: is there a way to make a class for a UIButton that takes parameters such as width and height, and is it possible to declare this kind of class to a UIButton?
That's no problem at all. Create a category or subclass of UIButton. Define a custom init method like - (instancetype)initWithColor:(UIColor *)color size:(CGSize)size. In the init method call self = [super initWithFrame:CGRectZero] and then set those properties on self.
About the frequently used style, you can make a method which return a styled button.
- (UIButton *)styledButtonWithFrame:(CGRect)frame
{
UIButton *btn = [[UIButton alloc] initWithFrame:frame];
[btn setBackgroundColor:[UIColor redColor]];
[btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
return btn;
}
and you can create an instance of styledButton
UIButton *styledBtn = [self styledButtonWithFrame:CGRectMake(0, 0, 10, 10)];
The second question, you can use category.
#interface UIView (BKExpansion)
#property (nonatomic, assign) CGFloat frameX;
#property (nonatomic, assign) CGFloat frameHeight;
#end
#implementation UIView (BKExpansion)
- (CGFloat)frameX
{
return self.frame.origin.x;
}
- (void)setFrameX:(CGFloat)frameX
{
CGRect frame_ = self.frame;
frame_.origin.x = frameX;
self.frame = frame_;
}
- (CGFloat)frameWidth
{
return self.frame.size.width;
}
- (void)setFrameWidth:(CGFloat)frameWidth
{
CGRect frame_ = self.frame;
frame_.size.width = frameWidth;
self.frame = frame_;
}
#end
You can add frameY, frameBottom, and so on.
If you want to change frameX or frameWidth, just use
[styledBtn setFrameY:30];
I've created 5 UIView dynamically, which consists of one UILabel and one UIButton each. When I click button, the UIView will setHidden. But it works only on one not other four uiviews.

Kindly help me. I am new in iOS development. I need here to create UIView with differrnt reference and that reference assign to UIButton to close that particular UIView but I could not get result out.
You could use UISegmentedControl along with number of xib for each UIView.
In each UIView you can place the required UIControls and link the same.
In the delegate method of SegmentedControl 'indexDidChangeForSegmentedControl:(UISegmentedControl *)sender' on each index remove the earlier UIView and add the required UIView.
In the main header file add the IBOutlet for each UIView
#property (nonatomic, weak) IBOutlet UIView *view1;
#property (nonatomic, weak) IBOutlet UIView *view2;
In .m file in the delegate method 'indexDidChangeForSegmentedControl'
- (IBAction)indexDidChangeForSegmentedControl:(UISegmentedControl *)sender {
NSUInteger index = sender.selectedSegmentIndex;
if (UISegmentedControlNoSegment != index) {
if (currentIndex == index) {
return;
}
currentIndex = index;
switch (index) {
case 0:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view1];
self.previousView = view1;
}
break;
case 1:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view2];
self.previousView = view2;
}
break;
}
}
}
Hope this helps.
If you want to use properties, you will have to make a property for each view. Instead, if you want to create them dynamicaly you could store the references to each view in an array.
The next you should know/do is to add a tag to each button. A tag is just a number, which in this case should reference to its position in the Array.
Then based on the button tag (that you can retrieve from the sender) you can retrieve the proper view/button from the array and change the Hidden property on it.
For example (pseudo code/this wont compile):
Creating the views array
#property (nonatomic, strong) NSMutableArray *views;
In View did load create the views
views = [[NSMutableArray alloc] init];
int nrOfViews = 5;
for(int a=0; a<=nrOfViews; a++){
UIView *view = create UIView here.
UIButton *button = create button here.
[view addSubView: button];
[button setTag: a];
[views addObject: view];
}
reference to the view through the pointer retained in the array, find the right one based on the button tag.
-(void)buttonPressed:(UIButton *)sender
{
UIView *view = [views objectAtIndex: sender.tag]; //using the button tag to identify the right view.
[view setHidden: yes];
}
Try something like this:
- (void) buttonPressed: (UIButton*) sender
{
UIView* view = sender.superview;
view.hidden = YES;
}
You need to make some changes as follows
#property(nonatomic,strong)IBOutlet UILabel *welcome; // new arc code
#property(nonatomic,strong)UIView *custom; // new arc code
self.custom = [[UIView alloc]initWithFrame:CGRectMake(20, yAxis, 100, 44)];
