UItextfield adding extra spaces beneath timestamp - objective-c

I have a relatively simple comment box (UITextfield) for a photo app into which I've found that when entering long comments (usually more than half a dozen words) a lot of blank space appears below the timestamp ("X minutes ago") within the comment box. The longer the post, the more blank space appears within the box. Everything else works fine, the comment is vertically aligned correctly, and the timestamp is directly below this.
self.backgroundColor = [UIColor clearColor];
mainView = [[UIView alloc] initWithFrame:CGRectMake( 20.0f, 0.0f, 280.0f, 51.0f)];
mainView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"BackgroundComments.png"]];
[self addSubview:mainView];
UIImageView *messageIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"IconAddComment.png"]];
messageIcon.frame = CGRectMake( 9.0f, 17.0f, 19.0f, 17.0f);
[mainView addSubview:messageIcon];
UIImageView *commentBox = [[UIImageView alloc] initWithImage:[[UIImage imageNamed:#"TextFieldComment.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(5.0f, 10.0f, 5.0f, 10.0f)]];
commentBox.frame = CGRectMake(35.0f, 8.0f, 237.0f, 35.0f);
[mainView addSubview:commentBox];
commentField = [[UITextField alloc] initWithFrame:CGRectMake( 40.0f, 10.0f, 227.0f, 31.0f)];
commentField.font = [UIFont systemFontOfSize:14.0f];
commentField.placeholder = #"Add a comment";
commentField.returnKeyType = UIReturnKeySend;
commentField.textColor = [UIColor colorWithRed:73.0f/255.0f green:55.0f/255.0f blue:35.0f/255.0f alpha:1.0f];
commentField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
[commentField setValue:[UIColor colorWithRed:154.0f/255.0f green:146.0f/255.0f blue:138.0f/255.0f alpha:1.0f] forKeyPath:#"_placeholderLabel.textColor"];
[mainView addSubview:commentField];
Any help would be much appreciated!

Cannot change the Y cordinate of the UILabel programmatically

hi Im programmatically creating an UILabel like this
`
- (UILabel *)titleLabel {
if (!_titleLabel) {
_titleLabel = [[[UILabel alloc] init] initWithFrame:CGRectMake(0.0, _photoView.frame.size.height, _photoView.frame.size.width, 100.0)];
// _titleLabel.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.5];
_titleLabel.backgroundColor =[UIColor clearColor];
_titleLabel.textColor = [UIColor whiteColor];
_titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:14];
_titleLabel.textAlignment = NSTextAlignmentRight;
[self addSubview:_titleLabel];
}
return _titleLabel;
}`
this _photoView is an UIImageView I have created already. I want to change the UILabel View Y value. But the problem is when I change this second parameter label y position is not changing. Any one can tell e the reason for this.
And this is how I created the ImageView
`
- (UIImageView *)photoView {
if (!_photoView) {
_photoView = [[UIImageView alloc] init];
_photoView.contentMode = UIViewContentModeScaleAspectFill;
_photoView.clipsToBounds = YES;
_photoView.layer.cornerRadius = 5;
_photoView.clipsToBounds = YES;
[self addSubview:_photoView];
}
return _photoView;
}`
Thanks
In this line , you have used two types init
[[[UILabel alloc] init] initWithFrame:CGRectMake(0.0, _photoView.frame.size.height, _photoView.frame.size.width, 100.0)]
change this line to
[[UILabel alloc] initWithFrame:CGRectMake(0.0, _photoView.frame.size.height, _photoView.frame.size.width, 100.0)]

Strange behaviour when laying out subviews

I am creating a UI that the user can page through multiple views by using a UIScrollView. I create the UIView objects in code and add them to UIScrollView. I use the code below to create the views.
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
UIView *brandView = [[UIView alloc] initWithFrame:frame];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 50.0, frame.size.width, 30)];
label.text = [brand objectForKey:#"name"];
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor redColor];
[brandView addSubview:label];
UIImageView *logoImageView = [[UIImageView alloc] init];
logoImageView.frame = CGRectMake(20.0, 100.0, 280.0, 300.0);
[brandView addSubview:logoImageView];
logoImageView.file = [brand objectForKey:#"logo"];
[logoImageView loadInBackground];
Although I give 50.0 for the y coordinate for the label, I can't see the label at all when I run the app. And logoImageView has 100.0 for its top but it appears just below the status bar, as if it had 0.0 for it's y coordinate.
What is the reason for this strange behaviour, am I doing something wrong?
Note: Auto layout for the UIScrollView is disabled on IB.
Below code will work for you !
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * 10;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
UIView *brandView = [[UIView alloc] init]; // CHANGE THAT HAS TO BE DONE
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 50.0, self.scrollView.frame.size.width, 30)];
label.text = #"Test";
label.textAlignment = UITextAlignmentCenter; // DEPRECATED IN iOS 6.0
label.backgroundColor = [UIColor redColor];
[brandView addSubview:label];
[self.scrollView addSubview:brandView];

self.navigationItem.titleView cutting off UIBarButtonItem after rotation

I use a self.navigationItem.titleView and I set two UIButtons as the self.navigationItem.rightBarButtonItems in the UINavigationBar. I have achieved this in my navigationBar like so
Whenever I rotate the view controller landscape and then back, the uibarbutton item gets cut off like so
The code I use to set the titleView is this:
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 44)];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.numberOfLines = 2;
titleLabel.font = [UIFont boldSystemFontOfSize:13.0f];
titleLabel.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.textColor = [UIColor whiteColor];
titleLabel.text = self.tabTitle;
self.navigationItem.titleView = titleLabel;
I have no idea why this is happening and I wonder if if any of you know how to fix this.

setting alpha of UITextField inputAccessoryView does not work

The inputAccessoryView is shown successfully, but it is totally black.
_textField = [[UITextField alloc] initWithFrame: CGRectZero]; // update frame later
_textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
UIView *inputAccessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 180)];
inputAccessoryView.backgroundColor = [UIColor blackColor];
inputAccessoryView.alpha = 0.2;
_textField.inputAccessoryView = inputAccessoryView;
I am completely confused over this... can anyone explain why it happens?
Use This method of UIColor on previous line instead of setting alpha:-
[UIColor colorWithHue:saturation:brightness:alpha:];

Showing a Title and an Image Into the Table Header

I am trying to show into the header of my UITableViewController a title and under it an image illustrating the title. The next code (written into the viewDidLoad method) shows only the image, and this image over the rest of the table sections. How I can fix it to do what I want?
// Creates a header view.
UIView *containerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)] autorelease];
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 40)] autorelease];
headerLabel.text = self.name;
headerLabel.textColor = [UIColor blackColor];
headerLabel.font = [UIFont boldSystemFontOfSize:16];
headerLabel.backgroundColor = [UIColor clearColor];
GRect imageRect = CGRectMake(0.0f, 0.0f, 320.0f, 109.0f);
UIImageView *headerImage = [[UIImageView alloc] initWithFrame:imageRect];
UIImage *image = [UIImage imageNamed:self.imagePath];
[headerImage setImage:image];
headerImage.opaque = YES;
[containerView addSubview:headerLabel];
[containerView addSubview:headerImage];
self.tableView.tableHeaderView = containerView;
Thanks for reading.
Just adjust the views' frames accordingly. The container view's frame must be tall enough to contain the label and image view, and the image view's y coordinate must be set so that it is positioned below the label. The frame rects you are using in your code do not match.
