I have text field, i need to show the cursor and hide the keyboard. It looks ok in the IOS 6 and IOS 5. But in IOS 7 i can see small white line on the bottom.
My code is
UIScrollView *scrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
[scrollview setDelegate:self];
[self.view addSubview:scrollview];
[self.view bringSubviewToFront:scrollview];
[scrollview setBackgroundColor:[UIColor blackColor]];
scrollview.contentSize = CGSizeMake(768, 1024);
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 500, 100)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.returnKeyType = UIReturnKeyDone;
[textField setUserInteractionEnabled:YES];
[textField setEnabled:YES];
[scrollview addSubview:textField];
// Here I need to show the cursor without showing keyboard
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
((UITextField*)textField).inputView = dummyView;
[((UITextField*)textField) becomeFirstResponder];
Anyone having any thought how to fix this?
I think this is due to the keyboard view, whose having the height as 1.
So if you change the line
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
to
UIView* dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
it will work.

Now i am hardcoding the origin x, y and everything. I want to use auto layout so that the left image and right image act as leading and trailing icon.
any suggestion?
Tried something like below, but not working:
`
[leftImageView setTranslatesAutoresizingMaskIntoConstraints:NO];
NSLayoutConstraint *leftImageViewConstraint = [NSLayoutConstraint constraintWithItem: leftImage attribute: NSLayoutAttributeLeading relatedBy: NSLayoutRelationEqual toItem: headerView attribute: NSLayoutAttributeLeading multiplier: 1 constant: 0];
[leftImageView addConstraints: #[leftImageViewConstraint]];
`
You need to activate each constraint that you add. When you have a bunch of constraints to set it's a lot easier to use NSLayoutConstraint activateConstraints. And using the various "anchor" properties for setting up the constraints is simpler than using the long form of creating an NSLayoutConstraint.
Here's your code updated with lots of constraints:
UIView* headerView = [[UIView alloc] initWithFrame:CGRectMake(8, 8, frameWidth, frameHeight)];
headerView.backgroundColor = UIColorFromRGB(0x5F70B9);
UIImage* leftImage = [UIImage imageNamed: #"search_list"];
UIImageView* leftImageView = [[UIImageView alloc] initWithImage: leftImage];
UITextView* textView = [[UITextView alloc] initWithFrame:CGRectZero];
textView.backgroundColor = UIColorFromRGB(0x5F70B9);
textView.textColor = UIColorFromRGB(0xFFFFFF);
textView.font = [UIFont preferredFontForTextStyle:UIFontTextStyleTitle3];
textView.text = STLocalizedString(#"message_overall_non_reply");
textView.editable = NO;
UIImage* rightImage = [UIImage imageNamed: #"arrow_mask"];
UIImageView* rightImageView = [[UIImageView alloc] initWithImage: rightImage];
leftImageView.translatesAutoresizingMaskIntoConstraints = NO;
textView.translatesAutoresizingMaskIntoConstraints = NO;
rightImageView.translatesAutoresizingMaskIntoConstraints = NO;
[headerView addSubview: leftImageView];
[headerView addSubview: textView];
[headerView addSubview: rightImageView];
[NSLayoutConstraint activateConstraints:#[
[leftImageView.leadingAnchor constraintEqualToAnchor:headerView.leadingAnchor constant:10],
//[leftImageView.topAnchor constraintEqualToAnchor:headerView.topAnchor constant:15],
[leftImageView.centerYAnchor constraintEqualToAnchor:headerView.centerYAnchor],
[leftImageView.widthAnchor constraintEqualToConstant:70],
[leftImageView.heightAnchor constraintEqualToConstant:50],
[rightImageView.trailingAnchor constraintEqualToAnchor:headerView.trailingAnchor constant:-10],
//[rightImageView.topAnchor constraintEqualToAnchor:headerView.topAnchor constant:30],
[rightImageView.centerYAnchor constraintEqualToAnchor:headerView.centerYAnchor],
[rightImageView.widthAnchor constraintEqualToConstant:15],
[rightImageView.heightAnchor constraintEqualToConstant:20],
[textView.leadingAnchor constraintEqualToAnchor:leftImageView.trailingAnchor constant:10],
[textView.trailingAnchor constraintEqualToAnchor:rightImageView.leadingAnchor constant:-10],
[textView.topAnchor constraintEqualToAnchor:headerView.topAnchor constant:20],
[textView.bottomAnchor constraintEqualToAnchor:headerView.bottomAnchor constant:-20],
]];
I made a few guesses here. Obviously you can change these to suit your needs.
How to make UITextField on background of UITableView?
I want to set textField in the top and when i scroll tableView my textField don't move.
Something like this
- (void)viewDidLoad {
[super viewDidLoad];
self.textField = [[UITextField alloc] initWithFrame:CGRectMake(20, 30, 100, 30)];
self.textField.backgroundColor = [UIColor redColor];
self.tableView = [[UITableView alloc] initWithFrame:self.tableView.frame style:UITableViewStyleGrouped];
self.tableView.contentInset = UIEdgeInsetsMake(50, 0, 0, 0);
[self.tableView registerClass:[TableViewCell class] forCellReuseIdentifier:NSStringFromClass([TableViewCell class])];
[self.view addSubview:self.textField];
}
You have another solution - besides one suggested in comments:
You can create UIViewController with tableView and text field. Assign delegate and dataSource to the view controller. Pin text field to the top and you have your desired behaviour. You will have to connect tableView with IBOutlets.
If you want to set textField in the top change textField frame
From
self.textField = [[UITextField alloc] initWithFrame:CGRectMake(20, 300, 100, 30)];
To
self.textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 30, 100, 30)];
self.textField.backgroundColor = [UIColor redColor];
[self.view addSubview:self.textField];
Also another solution is add textField to navigation item title.I tried this and it works fine.
textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 30, 100, 30)];
textField.backgroundColor = [UIColor redColor];
[self.view addSubview:textField];
self.navigationItem.titleView = self.textField;
I have an application in landscape mode, now I am adding a view in appdelegate but it's showing as in portrait mode. it is 90 degree rotated
below is my code added in appdelegate
-(void)addProcessingView{
UIView*container = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 500, 100)] autorelease];
container.backgroundColor = [UIColor grayColor];
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(100, 0, 400, 100)] autorelease];
[container addSubview:label];
UIActivityIndicatorView *active = [[[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0, 0, 100 , 100)] autorelease];
[container addSubview:active];
container.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[self.window addSubview:container];
container.center = self.window.center;
}
See image
I think you have to change the frame size of the view. Replace below line into your code.It will sort out your problem.
UIView*container = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 500)] autorelease];
I can not get rid of this strange spacing between line 0 and 1.
I want the same spacing between lines 0 and 1 as I have between line 1 and 2.
[self.tableView setBackgroundColor:TABLE_VIEW_BACKGROUND_COLOR];
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 250)];
UIImageView *headerBackgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"addres_box"]];
[headerBackgroundImageView setFrame:CGRectMake(headerView.frame.origin.x + 10, headerView.frame.origin.y + 10, headerView.frame.size.width - 20, 160)];
[headerView addSubview:headerBackgroundImageView];
UILabel *headerTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(headerBackgroundImageView.frame.origin.x + 10, headerBackgroundImageView.frame.origin.y + 10, headerBackgroundImageView.frame.size.width - 20, 20)];
[headerTextLabel setBackgroundColor:[UIColor clearColor]];
[headerTextLabel setFont:[UIFont boldSystemFontOfSize:headerTextLabel.font.pointSize]];
[headerTextLabel setTextColor:[UIColor whiteColor]];
[headerTextLabel setLineBreakMode:UILineBreakModeTailTruncation];
[headerTextLabel setNumberOfLines:0];
NSString *headerTextString = #"0";
NSString *detailTextString = #"1\n2";
[headerTextLabel setText:headerTextString];
[headerView addSubview:headerTextLabel];
_headerTextLabel = headerTextLabel;
UILabel *headerDetailTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(headerTextLabel.frame.origin.x, headerTextLabel.frame.origin.y+20, headerTextLabel.frame.size.width, 140)];
[headerDetailTextLabel setBackgroundColor:[UIColor clearColor]];
[headerDetailTextLabel setTextColor:[UIColor whiteColor]];
[headerDetailTextLabel setLineBreakMode:UILineBreakModeTailTruncation];
[headerDetailTextLabel setNumberOfLines:0];
[headerDetailTextLabel setText:detailTextString];
[headerView addSubview:headerDetailTextLabel];
_headerDetailTextLabel = headerDetailTextLabel;
[self.tableView setTableHeaderView:headerView];
[self.tableView setSeparatorColor:TABLE_VIEW_SEPARATOR_COLOR];
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
I hope someone can help me!
Perhaps your headerDetailTextLabel is centered vertically, try adding more lines like "1\n2\n3\n4" and see the result.
Thanks for the hints, I solved it by adding "sizeToFit" and now every things look good
[headerDetailTextLabel setText:detailTextString];
[headerDetailTextLabel sizeToFit]; //this line fixed the spacing problem
[headerView addSubview:headerDetailTextLabel];
I used the below codes
CGRect scrollserviceViewFrame1 = CGRectMake(60,610, 650, 150);
//CGRect scrollViewFrame =[[UIScreen mainScreen] applicationFrame];
//UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollViewFrame];
UIScrollView *servicescrollView1 = [[UIScrollView alloc] initWithFrame:scrollserviceViewFrame1];
[self.view addSubview:servicescrollView1];
//scrollView.backgroundColor=[UIColor greenColor];
[servicescrollView1 setBackgroundColor:[UIColor redColor]];
[servicescrollView1 setCanCancelContentTouches:NO];
//scrollView.indicatorStyle = UIScrollViewIndicatorStyleBlack;
servicescrollView1.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview
servicescrollView1.scrollEnabled = YES;
servicescrollView1.autoresizesSubviews=YES;
[servicescrollView1 setContentSize: CGSizeMake(1050, 100)];
//scrollView.delegate = self;
servicescrollView1.pagingEnabled = YES;
servicescrollView1.showsHorizontalScrollIndicator = NO;
[servicescrollView1 scrollRectToVisible:CGRectMake(servicescrollView1.frame.size.width, 0, self.view.frame.size.width, self.view.frame.size.height) animated:YES];
NSLog(#" scroll view width :%i ",servicescrollView1.frame.size.width);
NSLog(#"scroll view height :%i ",self.view.frame.size.height);
NSLog(#"self view width :%i",self.view.frame.size.width);
CGRect CGRectZero = CGRectMake(60,710,200, 100);
UIView* myserviceView1 = [[UIView alloc] initWithFrame: CGRectZero];
myserviceView1.backgroundColor=[UIColor blackColor];
[servicescrollView1 addSubview:myserviceView1];
[myserviceView1 release];
[servicescrollView1 release];
The scroll view is created , butcannot add the UIVIew to scrollview...
Any suggestions for solving this query???
Thanks in advance
Near the bottom of your code where you create myserviceView1, you (attempt to) reset a constant (CGRectZero).
And then when you create your myserviceView1 UIView, you're giving it a frame size of {0, 0, 0, 0}.
