I want to draw a circle with text inside.Unable to display text.Any help?
Below image is ref. for expected behaviour.
Below is the code for reference:
UILabel *lblTitle = [[UILabel alloc]initWithFrame:CGRectMake(100, 40, 40, 40)];
lblTitle.text = #"Me";
lblTitle.textColor = [UIColor blackColor];
lblTitle.font = [UIFont fontWithName:#"HelveticaNeueLight" size:10.0] ;
lblTitle.textAlignment = NSTextAlignmentCenter;
[view addSubview:lblTitle];
CAShapeLayer *circleLayer = [CAShapeLayer layer];
circleLayer.path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(0, 0, 40, 40)].CGPath;
circleLayer.fillColor = [UIColor clearColor].CGColor;
circleLayer.fillColor = [UIColor colorWithRed:56.0/255.0 green:212.0/255.0 blue:203.0/255.0 alpha:1.0f].CGColor;
circleLayer.strokeColor = [UIColor blackColor].CGColor;
circleLayer.lineWidth = 1;
[lblTitle.layer addSublayer:circleLayer];
You can setting cornerRadius of UILabel as #Sujay said:
UILabel *lblTitle = [[UILabel alloc]initWithFrame:CGRectMake(100, 80, 40, 40)];
lblTitle.text = #"Me";
lblTitle.textColor = [UIColor blackColor];
lblTitle.layer.borderWidth = 1;
lblTitle.layer.borderColor = [UIColor blackColor].CGColor;
lblTitle.layer.cornerRadius = lblTitle.bounds.size.height / 2;
lblTitle.layer.masksToBounds = YES;
lblTitle.backgroundColor = [UIColor colorWithRed:56.0/255.0 green:212.0/255.0 blue:203.0/255.0 alpha:1.0f];
lblTitle.font = [UIFont fontWithName:#"HelveticaNeueLight" size:10.0] ;
lblTitle.textAlignment = NSTextAlignmentCenter;
[self.view addSubview:lblTitle];

how to set tableview scroll smooth and effective
how to set interface properties
tableview data is static
Use reusable UITableViewCell inside function viewForHeaderInSection and inside viewForFooterInSection
Do not create the new UIView and buttons for each function call.
Your table view scrolling is not smooth because the views inside viewForHeaderInSection and viewForFooterInSection methods are allocated multiple times. Why ? Because whenever you scroll up and down, both the methods are called as and when required.
Check whether header view is already allocated. If it is nil, then and then allocate it and return it. Otherwise, just return it. Same way in case of footer view.
Add comment in case of any doubt..
I am trying to put transparency (or a color gradient) on the title of an UIButton. I don't know how do that. I have tried to simply put a clearColor on the titleColor but we only see the background color.
So i hope that there is someone here who will be an amazing idea for my problem.
My solution
self.loginButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.loginButton.backgroundColor= [UIColor whiteColor];
self.loginButton.frame = CGRectMake(self.signUpButton.left,
0,
self.signUpButton.frame.size.width,
self.signUpButton.frame.size.height);
[self.loginButton.layer setBackgroundColor:[[UIColor blackColor] CGColor]];
self.loginButton.layer.borderColor = [[UIColor whiteColor] CGColor];
self.loginButton.layer.borderWidth = 1.0f;
self.loginButton.layer.cornerRadius = 3.0f;
[self.loginButton addTarget:self action:#selector(loginButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
self.loginButtonLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
self.loginButtonLabel.font = [UIFont fontWithName:#"OpenSans-Light" size:16.0f];
self.loginButtonLabel.textColor = [UIColor whiteColor];
self.loginButtonLabel.text = #"Connexion";
[self.loginButtonLabel sizeToFit];
UIColor *topColor = [UIColor blueColor];
UIColor *bottomColor = [UIColor orangeColor];
self.gradientView = [[UIView alloc] initWithFrame:self.loginButtonLabel.frame];
[self.loginButton addSubview:self.gradientView];
[self.loginButton sendSubviewToBack:self.gradientView];
[self.loginButton addSubview:self.loginButtonLabel];
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.gradientView.frame;
gradient.colors = [NSArray arrayWithObjects:(id)topColor.CGColor, (id)bottomColor.CGColor, nil];
gradient.startPoint = CGPointMake(0, 0.5);
gradient.endPoint = CGPointMake(1, 0.5);
[self.gradientView.layer addSublayer:gradient];
self.gradientView.layer.mask = self.loginButtonLabel.layer;
self.gradientView.layer.masksToBounds = YES;
self.gradientView.center = CGPointMake(self.loginButton.width / 2, self.loginButton.height / 2);
[self.view addSubview:self.loginButton];
But Now i need to put the gradient on the border. Any idea ?
So my solution is to create a custom button with an UILabel. I will use an UIView with a gradient for color the text.
The solution :
self.loginButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.loginButton.backgroundColor= [UIColor whiteColor];
self.loginButton.frame = CGRectMake(self.signUpButton.left,
0,
self.signUpButton.frame.size.width,
self.signUpButton.frame.size.height);
[self.loginButton.layer setBackgroundColor:[[UIColor blackColor] CGColor]];
self.loginButton.layer.borderColor = [[UIColor whiteColor] CGColor];
self.loginButton.layer.borderWidth = 1.0f;
self.loginButton.layer.cornerRadius = 3.0f;
[self.loginButton addTarget:self action:#selector(loginButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
self.loginButtonLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
self.loginButtonLabel.font = [UIFont fontWithName:#"OpenSans-Light" size:16.0f];
self.loginButtonLabel.textColor = [UIColor whiteColor];
self.loginButtonLabel.text = #"Connexion";
[self.loginButtonLabel sizeToFit];
UIColor *topColor = [UIColor blueColor];
UIColor *bottomColor = [UIColor orangeColor];
self.gradientView = [[UIView alloc] initWithFrame:self.loginButtonLabel.frame];
[self.loginButton addSubview:self.gradientView];
[self.loginButton sendSubviewToBack:self.gradientView];
[self.loginButton addSubview:self.loginButtonLabel];
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.gradientView.frame;
gradient.colors = [NSArray arrayWithObjects:(id)topColor.CGColor, (id)bottomColor.CGColor, nil];
gradient.startPoint = CGPointMake(0, 0.5);
gradient.endPoint = CGPointMake(1, 0.5);
[self.gradientView.layer addSublayer:gradient];
self.gradientView.layer.mask = self.loginButtonLabel.layer;
self.gradientView.layer.masksToBounds = YES;
self.gradientView.center = CGPointMake(self.loginButton.width / 2, self.loginButton.height / 2);
[self.view addSubview:self.loginButton];
I will drawing UILabel with code
CustomLabel *label = [[CustomLabel alloc] initWithFrame:CGRectMake(0, 0, 260, 100)];
label.layer.borderColor = [[UIColor redColor] CGColor];
label.layer.borderWidth = 3.0;
[label setFont:[UIFont fontWithName:#"Helvetica" size:16]];
CALayer * l1 = [label layer];
[l1 setMasksToBounds:YES];
[l1 setCornerRadius:10.0];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = NSTextAlignmentLeft; // UITextAlignmentCenter, UITextAlignmentLeft
label.textColor=[UIColor whiteColor];
label.backgroundColor = [UIColor redColor];
label.numberOfLines=4;
label.lineBreakMode=NSLineBreakByWordWrapping;
label.text = [NSString stringWithFormat:#"%#", message];
label.tag = index;
[label sizeToFit];
And of course, i will found a solution from stackoverflow for create padding for label
with code
- (id)initWithFrame:(CGRect)frame{
self = [super initWithFrame:frame];
if (self) {
self.edgeInsets = UIEdgeInsetsMake(5,5,5,5); //customize padding here
}
return self;
}
- (void)drawTextInRect:(CGRect)rect {
[super drawTextInRect:UIEdgeInsetsInsetRect(rect, self.edgeInsets)];
}
Everything working fine, but text in my label showing not good, here is my label screenshot.
I want like this.
Please help and thanks for your time.
you would want to have a look into this library.. its awesome and totally configurable...
https://github.com/AlexBarinov/UIBubbleTableView
In my UICollectionViewCell subclass I have this code to layout the subViews I want:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(97, 10, 190, 40)];
_titleLabel.font = [UIFont boldFlatFontOfSize:22];
_titleLabel.backgroundColor = [UIColor clearColor];
_fromLabel = [[UILabel alloc]initWithFrame:CGRectMake(97, 35, 190, 30)];
_fromLabel.font = [UIFont flatFontOfSize:14];
_fromLabel.backgroundColor = [UIColor clearColor];
UIView *containerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 90, 90)];
containerView.backgroundColor = [[UIColor colorWithPatternImage:[UIImage imageNamed:#"cream_pixels"]] colorWithAlphaComponent:0.8];
[self.contentView addSubview:containerView];
_iconView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 50, 50)];
[_iconView setCenter:containerView.center];
_iconView.backgroundColor = [UIColor whiteColor];
_iconView.contentMode = UIViewContentModeScaleAspectFit;
_iconView.image = [UIImage imageNamed:#"envelopeIcon.png"];
_iconView.backgroundColor = [UIColor clearColor];
[containerView addSubview:_iconView];
_dateLabel = [[UILabel alloc]initWithFrame:CGRectMake(97, self.contentView.frame.size.height - 23, self.contentView.frame.size.width-97, 25)];
[_dateLabel setBackgroundColor:[UIColor clearColor]];
[_dateLabel setFont:[UIFont boldFlatFontOfSize:13]];
[_dateLabel setTextColor:[[UIColor wetAsphaltColor] colorWithAlphaComponent:0.6f]];
[_dateLabel setTextAlignment:NSTextAlignmentLeft];
[_dateLabel setLineBreakMode:NSLineBreakByCharWrapping];
[_dateLabel setNumberOfLines:0];
_typeLabel = [[UILabel alloc]initWithFrame:CGRectMake(0.f, 0.f , 4, self.contentView.frame.size.height)];
_typeLabel.layer.cornerRadius = 0.f;
_typeLabel.backgroundColor = [UIColor belizeHoleColor];
[self.contentView addSubview:_titleLabel];
[self.contentView addSubview:_fromLabel];
[self.contentView addSubview:_typeLabel];
[self.contentView addSubview:_dateLabel];
self.backgroundColor = [[UIColor cloudsColor] colorWithAlphaComponent:1.f];
self.layer.cornerRadius = 3.2f;
self.layer.masksToBounds = NO;
self.layer.contentsScale = [UIScreen mainScreen].scale;
self.layer.borderColor = [[UIColor silverColor] colorWithAlphaComponent:0.2].CGColor;
self.layer.borderWidth = 0.5f;
self.layer.shadowOpacity = 0.35f;
self.layer.shadowRadius = 3.f;
self.layer.shadowOffset = CGSizeMake(0, 3.f);
self.layer.shadowPath = [UIBezierPath bezierPathWithRect:self.bounds].CGPath;
self.layer.shouldRasterize = YES;
[_titleLabel setText:#"Nuevo Mensaje"];
}
return self;
}
I understand that for performance, it's recommended that the subviews are added to the cell using custom drawing, and not by layering the contents of it.
How can I achieve this?
Why won't my UIView (created below) show up in the UITableViewHeader that I try to add it to?
UIView *view = [[UIView alloc] initWithFrame: CGRectMake ( 20, 20, 400, 400)];
searchBar = (UISearchBar *)self.tableView.tableHeaderView;
[searchBar.subviews objectAtIndex:0] removeFromSuperview];
searchBar.backgroundColor = [UIColor clearColor];
[view addSubview:searchBar];
self.tableView.tableHeaderView = nil;
view.backgroundColor = [UIColor redColor];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 60, self.view.frame.size.width, 60)];
label.shadowColor = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:.35];
label.shadowOffset = CGSizeMake(0, -1.0);
label.text = #"188 People";
label.textColor = [UIColor grayColor];
label.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:12.0];
label.backgroundColor = [UIColor clearColor];
[view addSubview:label];
self.tableView.tableHeaderView = view;
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *view = [[UIView alloc] initWithFrame: CGRectMake ( 20, 20, 400, 400)];
searchBar = (UISearchBar *)self.tableView.tableHeaderView;
[searchBar.subviews objectAtIndex:0] removeFromSuperview];
searchBar.backgroundColor = [UIColor clearColor];
[view addSubview:searchBar];
view.backgroundColor = [UIColor redColor];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 60, self.view.frame.size.width, 60)];
label.shadowColor = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:.35];
label.shadowOffset = CGSizeMake(0, -1.0);
label.text = #"188 People";
label.textColor = [UIColor grayColor];
label.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:12.0];
label.backgroundColor = [UIColor clearColor];
[view addSubview:label];
return view;//Please note the header will look the same for each section. You can add a switch or if/else to augment this
}
-As a side note, if you're planning on using the label here to set the text for the header, I suggest looking into the following methods:
-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section;
