I am setting a label inside of an empty table view's background view, which is placing the label in the middle of the tableview.
I'd like to move that label up a bit, so it's near the top of the table view, however the code below isn't working:
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, 20)];
messageLbl.text = #"NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
[messageLbl sizeToFit];
//set back to label view
self.tableView.backgroundView = messageLbl;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.backgroundView.frame = CGRectMake(0, 0, self.tableView.bounds.size.width, 100);
Another easy solution is to add your messageLbl to tableHeaderView:
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, 50)];
messageLbl.text = #"\n\n NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
messageLbl.numberOfLines = 0;
[messageLbl sizeToFit];
//set back to label view
self.tableView.tableHeaderView = messageLbl;
Quick solution is just by adding \n at the end the of text and set no of lines to 0. Try this
messageLbl.numberOfLines = 0;
messageLbl.text = #"NO REGISTRATIONS FOUND\n\n\n\n";
Looks like you were hiding the Y axis behind Navigation bar
try it by setting some Y axis height & Don't forget to add SubView
UILabel *messageLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 100, self.tableView.bounds.size.width, 20)];
messageLbl.text = #"NO REGISTRATIONS FOUND";
messageLbl.font = [UIFont fontWithName:#"Sansation-Bold" size:20.0f];
messageLbl.textColor = [UIColor lightGrayColor];
messageLbl.textAlignment = NSTextAlignmentCenter;
[messageLbl sizeToFit];
//set back to label view
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
[self.view addSubview: messageLbl];

I've to create a view in objective c with two labels on it, label1 has single line and label2 is multi line based on content.
Based on content in the labels I want to adjust view height how can I do that?
Width of the view should be 20 left and right to screen width with below code I can show in portrait but in landscape it was not coming properly, It crops on the right side. How can I do show that right 20 for landscape?
Portrait
Landscape
UIView *emptyTreeView = [[UIView alloc] initWithFrame:CGRectMake(20,20,self.view.frame.size.width - 40,400)];
UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(30.0, 30.0, self.view.frame.size.width - 100, 30.0)];
UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(30.0, 90.0, self.view.frame.size.width - 100, 100.0)];
emptyTreeView.backgroundColor=[UIColor blueColor];
label1.backgroundColor = [UIColor redColor];
label1.textAlignment = NSTextAlignmentCenter;
label1.textColor = [UIColor blackColor];
label1.font = [UIFont boldSystemFontOfSize:18];
label1.numberOfLines = 0;
label1.text = #"The Page Cannot be displayed.";
label2.backgroundColor = [UIColor whiteColor];
label2.textAlignment = NSTextAlignmentCenter;
label2.textColor = [UIColor grayColor];
label2.font = [UIFont systemFontOfSize:15];
label2.numberOfLines = 0;
label2.text = #"Please use this feature or contact your internal contact person directly.";
[emptyTreeView addSubview:label1];
[emptyTreeView addSubview:label2];
[self.view addSubview:emptyTreeView];
Am I doing anything wrong?
A few observations:
Do not add subviews in viewDidLayoutSubviews. That is only for adjusting frame values.
If you refer to self.view, reference its bounds, not its frame. The former is for coordinates of subviews within self.view. The latter is in the coordinate system of its superview (which might not introduce any differences right now, but is just the wrong coordinate system.
If you want the view to resize on rotation, set its autoresizingMask, e.g.
emptyTreeView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
Or
emptyTreeView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin;
Nowadays, setting frame values and autoresizing masks is a bit of an anachronism. We would generally use constraints, e.g.
- (void)viewDidLoad {
[super viewDidLoad];
UIView *emptyTreeView = [[UIView alloc] init];
UILabel *label1 = [[UILabel alloc] init];
UILabel *label2 = [[UILabel alloc] init];
emptyTreeView.backgroundColor = [UIColor blueColor];
label1.backgroundColor = [UIColor redColor];
label1.textAlignment = NSTextAlignmentCenter;
label1.textColor = [UIColor blackColor];
label1.font = [UIFont boldSystemFontOfSize:18];
label1.numberOfLines = 0;
label1.text = #"The Page Cannot be displayed.";
label2.backgroundColor = [UIColor whiteColor];
label2.textAlignment = NSTextAlignmentCenter;
label2.textColor = [UIColor grayColor];
label2.font = [UIFont systemFontOfSize:15];
label2.numberOfLines = 0;
label2.text = #"Please use this feature or contact your internal contact person directly.";
[emptyTreeView addSubview:label1];
[emptyTreeView addSubview:label2];
[self.view addSubview:emptyTreeView];
emptyTreeView.translatesAutoresizingMaskIntoConstraints = false;
label1.translatesAutoresizingMaskIntoConstraints = false;
label2.translatesAutoresizingMaskIntoConstraints = false;
[NSLayoutConstraint activateConstraints:#[
[emptyTreeView.leftAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.leftAnchor constant:20],
[emptyTreeView.rightAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.rightAnchor constant:-10],
[emptyTreeView.topAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.topAnchor constant:20],
[label1.leftAnchor constraintEqualToAnchor:emptyTreeView.leftAnchor constant:20],
[label1.rightAnchor constraintEqualToAnchor:emptyTreeView.rightAnchor constant:-20],
[label1.topAnchor constraintEqualToAnchor:emptyTreeView.topAnchor constant:20],
[label2.leftAnchor constraintEqualToAnchor:emptyTreeView.leftAnchor constant:20],
[label2.rightAnchor constraintEqualToAnchor:emptyTreeView.rightAnchor constant:-20],
[label2.topAnchor constraintEqualToAnchor:label1.bottomAnchor constant:20],
[emptyTreeView.bottomAnchor constraintEqualToAnchor:label2.bottomAnchor constant:20]
]];
}
Note the translatesAutoresizingMaskIntoConstraints is false and the constraints.
My goal is to use title and subtitle with different font sizes in navigation controller page title (title should be bigger, subtitle should be lower accordingly).
I found example of code to implement this. The only one problem is that font size is not applied - both title and subtitle have the same font size. Like the code for font size doesn't work.
How to fix that? Thank you
// prepare title label
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor whiteColor];
titleLabel.font = [UIFont fontWithName:#"HelveticaNeueLight" size:19.0];
titleLabel.text = locationInfo;
[titleLabel sizeToFit];
// prepare subtitle label
UILabel *subtitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 18, 0, 0)];
subtitleLabel.backgroundColor = [UIColor clearColor];
subtitleLabel.textColor = [UIColor whiteColor];
subtitleLabel.font = [UIFont fontWithName:#"HelveticaNeueLight" size:12.0];
subtitleLabel.text = dateInfo;
[subtitleLabel sizeToFit];
UIView *twoLineTitleView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, MAX(subtitleLabel.frame.size.width, titleLabel.frame.size.width), 30)];
[twoLineTitleView addSubview:titleLabel];
[twoLineTitleView addSubview:subtitleLabel];
float widthDiff = subtitleLabel.frame.size.width - titleLabel.frame.size.width;
if (widthDiff > 0) {
CGRect frame = titleLabel.frame;
frame.origin.x = widthDiff / 2;
titleLabel.frame = CGRectIntegral(frame);
} else{
CGRect frame = subtitleLabel.frame;
frame.origin.x = fabs(widthDiff) / 2;
subtitleLabel.frame = CGRectIntegral(frame);
}
self.navigationItem.titleView = twoLineTitleView;
It's with the setFont method, not .font
[titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:12.0]];
And also you have an error in the font name:
it's HelveticaNeue-Light
Use SetFont instead of Font::
[titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-UltraLight" size:14.0]];
I have this code to add a footer view to my table view
UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(0.0f,0.0f,320.0f,80.0f)];
UILabel *tableFooter = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];
tableFooter.textColor = [UIColor blueColor];
tableFooter.backgroundColor = [self.tableView backgroundColor];
tableFooter.opaque = YES;
tableFooter.font = [UIFont boldSystemFontOfSize:15];
tableFooter.text = #"test";
[footerView addSubview:tableFooter];
self.tableView.tableFooterView = footerView;
but then I when I run this I do not see the label at the bottom of my code, I am it to my view, and then set my view as to footer, I see the extra space but not the label?
Not sure why this is happening?
Thanks
Hello in Xcode I am trying to add two labels to my image programmatically but when I add the second one it will overwrite my first one. Here is my code:
//first label
UILabel* caption = [[UILabel alloc] initWithFrame:
CGRectMake(-25, 0, 320, 50)
];
caption.backgroundColor = [UIColor whiteColor];
caption.textColor = [UIColor blackColor];
caption.textAlignment = UITextAlignmentLeft;
caption.font = [UIFont systemFontOfSize:16];
caption.text = [NSString stringWithFormat:#" #%#",[data objectForKey:#"username"]];
[self addSubview: caption];
//second label
UILabel* bottomBox = [[UILabel alloc] initWithFrame:
CGRectMake(-25, -200, 320, 50)
];
caption.backgroundColor = [UIColor whiteColor];
caption.textColor = [UIColor blackColor];
caption.textAlignment = UITextAlignmentCenter;
caption.font = [UIFont systemFontOfSize:16];
caption.text = [NSString stringWithFormat:#" Testing"];
[self addSubview: bottomBox];
I've tried changing the "0 to -200 to modify the Y coordinates so that the second label will shift down but it just overwrites the first one for some reason. Any help would be greatly appreciated thanks.
All the code for your 2nd label is referencing the 1st variable caption instead of bottomBox. You want:
//second label
UILabel* bottomBox = [[UILabel alloc] initWithFrame:CGRectMake(20, 200, 320, 50)];
bottomBox.backgroundColor = [UIColor whiteColor];
bottomBox.textColor = [UIColor blackColor];
bottomBox.textAlignment = UITextAlignmentCenter;
bottomBox.font = [UIFont systemFontOfSize:16];
bottomBox.text = #"Testing";
[self addSubview: bottomBox];
I'm using a UILabel as the leftView of a UITextField. The issue is that the textField's text is higher than the label's.
This is the code I've used so far
UILabel *startsWith = [[UILabel alloc] init];
startsWith.font = [UIFont systemFontOfSize:14];
startsWith.textColor = [UIColor blackColor];
startsWith.backgroundColor = [UIColor clearColor];
startsWith.text = #"Text";
[startsWith sizeToFit];
self.textField.leftViewMode = UITextFieldViewModeAlways;
self.textField.leftView = startsWith;
I've tried slightly changing the label's frame but it didn't work...
How can I align both texts?
You could create a container view in which you position the UILabel 1px up.
UIView * v = [[UIView alloc] init];
v.backgroundColor = [UIColor clearColor];
UILabel *startsWith = [[UILabel alloc] init];
startsWith.font = self.textfield.font;
startsWith.textAlignment = self.textfield.textAlignment;
startsWith.textColor = [UIColor blackColor];
startsWith.backgroundColor = [UIColor clearColor];
startsWith.text = #"Text";
[startsWith sizeToFit];
startsWith.frame = CGRectOffset(startsWith.frame, 0, -1);
v.frame = startsWith.frame;
[v addSubview:startsWith];
self.textfield.leftViewMode = UITextFieldViewModeAlways;
self.textfield.leftView = v;
