I have designed a xib whose configuration I have set as shown in the pic
I have added a UIImageView to the xib view and added proper constraints
So that the UIImageView appears full screen but the problem is that this works good for iPhone 5 but fails to scale on iPhone 6, I am not understanding the problem.
The UIImageView Configurations are as in the pic
To fill the UIImageView full screen, set the mode to Scale to fill. If it does not fill screen yet, then the size of image is not appropriate. i would recommend you to use vector graphics.
I was making a silly mistake while adding the UIView as subview I was not describing the frame
Describing the frame as,
[self.profileView setFrame:CGRectMake(0, 0, Get_Bounds.width, Get_Bounds.height - 64)];
This does the trick.
I am new to cocoa development.
Is there a way to reduce the height of a NSProgressIndicator from interface builder? I see the height is grayed out on 19 pt there!
I see also a size property with small and regular but what about I creating my own size?
I was not working with NSProgressIndicator but I worked a lot with UIProgressView (iOS analog of NSProgressIndicator). And it is impossible to change UIProgressView's height neither in IB neither by changing its frame property.
But there is a nice workaround! In iOS you can use transform property to change the height. Following will reduce height by 50%:
_progressView.transform = CGAffineTransformMakeScale(1.0f, 0.5f);
Maybe you can use the same workaround for NSProgressIndicator.
I have an UISegmentedControl with 100x42 bounds. I've set up three segments with 26x26 images and 4x42 divider images. The three segment images should fit in the segments, but they are scaled and for the worse they seem to fit vertically and are only scaled down horizontally, thus loosing proportions.
This problem appeared after i changed to Xcode 5 and iOS 7 SDK. Before that the segment images were displayed with correct proportions and in original size.
I'm not using interface builder. I've tried to set the segment sizes manually and setting the segmented control's contentMode to UIViewContentModeScaleAspectFill without help.
Is there any way to force the UISegmentedControl to simply render the images as they are?
You may set auto layout constraints to correctly define UISegmentedControl frame. Like this
I know this is a late answer but I have the same issue testing an app for IOS 7.1.
If you set the image in the code it's working properly. Example:
- (void)viewDidLoad {
[super viewDidLoad];
[_segmentedControl setImage:[UIImage imageNamed:#"779-users-toolbar"] forSegmentAtIndex:0];
}
In my project I have the normal image, and the #2x & #3x versions of the image.
I tested the code in 7.1, xcode 6.1.
When I run it in 8.1 the image set via IB works properly as well, so this may be a bug in 7.1 that has been fixed in 8.
Last week I asked a question about a Simulator bug with NSAttributedString not displaying: iOS 7 Simulator Bug - NSAttributedString does not appear
Unfortunately it now appears this is not a simulator bug but an iOS 7 bug. I have now reproduced this issue on an iPhone 5 device.
The bug appears to be the combination of using NSUnderlineStyleAttributeName & NSParagraphStyleAttributeName as attributes for a NSAttributedString.
I have only tested on two iOS 7 devices so far, and the issue has only appeared on one of them. Even after they have both been upgraded to the exact same version:
1st iPhone 5 with iOS 7.0 (11A465): Text does NOT appear
1st iPhone 5 after upgrading to 7.0.2 (11A501): Text does NOT appear
2nd iPhone 5 running iOS 7.0 (11A4449d): Text displays correctly
2nd iPhone 5 after upgrading to 7.0.2 (11A501): Text does NOT appear
So it appears Apple introduced this bug after iOS 7.0 (11A4449d). I've filed a bug with them and will update you on any response I get.
Steps to reproduce bug
If you are running iOS 7.0.2 then you should be able to reproduce this bug.
Either download and run this project on your device https://github.com/rohinnz/iOS-7-BUG---NSAttributedString-does-not-appear
or
1) In Xcode 5 create a new 'Single View Application'. Call it whatever.
2) In ViewController.m, replace the viewDidLoad method with:
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableParagraphStyle* paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.alignment = NSTextAlignmentCenter;
NSAttributedString* attrStr = [[NSAttributedString alloc] initWithString:#"Lorem ipsum dolor sit" attributes:
#{NSUnderlineStyleAttributeName:#(NSUnderlineStyleSingle),
NSParagraphStyleAttributeName:paragraph}];
UILabel* myLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 30, 0, 0)];
myLabel.backgroundColor = [UIColor greenColor];
myLabel.attributedText = attrStr;
[myLabel sizeToFit];
[self.view addSubview:myLabel];
}
3) Compile and run on your device. Depending on your version of iOS 7, the text will either display, or will not. The UILabel's background color will display in both cases.

My Question
Is anyone able to reproduce this issue on a device?
I have found a workaround for this bug. In your github code, to use the workaround, you would say this:
NSAttributedString* attrStr =
[[NSAttributedString alloc] initWithString:#"Lorem ipsum dolor sit\n" // <---
attributes:
#{NSUnderlineStyleAttributeName:#(NSUnderlineStyleSingle),
NSParagraphStyleAttributeName:paragraph}];
UILabel* myLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 30, 0, 0)];
myLabel.backgroundColor = [UIColor greenColor];
myLabel.attributedText = attrStr;
[myLabel sizeToFit];
myLabel.numberOfLines = 2; // <---
I have made two changes: I've appended a newline character to your original string, and I've set the label's numberOfLines to 2.
What the workaround does is to force the label's text up against the top of the label. This seems to solve the problem. In other words, the bug appears to stem from the label's attempt to vertically center its text; if you deliberately make the text too long for the size of the label by juggling the label's height, numberOfLines, and excess newline characters at the end of the text, the attributed string will be drawn.
EDIT I've just found another workaround along the same lines: let the label resize itself to fit the text. See my code and explanation here: https://stackoverflow.com/a/19545193/341994 In that code, I do the same thing from the opposite end, as it were: I give the label a fixed width constraint but a flexible height constraint, and by setting its own height, the label brings the top of its text up against the top of itself, and thus is able to display the text correctly. In other words, this is just another way of preventing the label from centering its text vertically, which is what seems to trigger the bug.
FURTHER EDIT I have the sense that this bug may get fixed in iOS 7.1.
I also had the same problem when setting the background color on text of a UILabel in a UITableViewCell. My workaround was to use a UITextView with UserInteraction disabled instead of a UILabel in the cell and it worked.
Update: Found the issue only appearing with UILabel included in Basic UITableViewCell.
Update 2: Also found that the problem does not occur when a UILabel wraps to multiple lines of text. One workaround is to force text to wrap by adding a newline and space. Very hacky, but it works. Make sure numberOfLines is set to zero and lineBreakMode is set to NSLineBreakByWordWrapping.
I had the same issue in my application. It was occurring in the simulators, as well as on my device (iPhone 5 running 7.0.2 (11A501)). I then realized that my UILabels living in other ViewControllers were displaying NSAttributedStrings using the NSUnderlineStyleSingle attribute properly.
After some troubleshooting. It seems that if you're using the default font (I'm using System 17.0) and your UILabel has a height of less than 62 pixels, it will display correctly regardless of what background color, text color, or alignment you are using. A change of the UILabel's height to a value greater than 61 pixels, allowing auto-sizing to change the height for you, or a change of the font to a Custom one will result in the disappearing of the underlined NSAttributedText.
At first I thought this issue might be due to my positioning the UILabel behind the new Status Bar (or lack thereof), but even in positions which would interact with this new feature, the height-rule still held. I find it hard to believe that the height of the UILabel would cause such an issue, but that's the conclusion I came to.
Wow, took me a while to find this. Looks like I'm have a similar problem as Indi. Setting the background color of an attributed string caused the text to just disappear. Only place I can reproduce this is on a device running iOS 7.0.3.
workaround: use an image view
CGRect rect = self.frame;
CGRect rr = [attribText boundingRectWithSize:rect.size options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesDeviceMetrics context:nil];
UIGraphicsBeginImageContextWithOptions(rr.size, NO, 0.);
[attribText drawWithRect:rr options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesDeviceMetrics context:nil];
UIImage* image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageView *imView = [[UIImageView alloc]initWithImage:image];
[self addSubview:imView];
I noticed this problem occurring in a similar way but ended up with a different solution. The string would sometimes disappear, while the solution proposed above helped ensure the text did not disappear, the text would often show up without any of the attributes I had set (strikethrough, different colours, etc.)
Here's the setup:
A legacy project using springs and struts being built using Xcode 6.1.1 and iOS SDK 8.1. The problem was more noticeable on iPad devices as compared to iPhone devices (~ 5% of the time on iPhones vs. 95% on iPads). Regardless whether I used numberOfLines, sizeToFit or other methods, the attributes would not show up correctly on an iPad or iPhone 100% of the time.
The solution was to switch to Auto Layout and employ the solution above (numberOfLines = 2, sizeToFit seemed optional for my situation)
It seems there's a bug with Attributed Text on UILabels with Springs and Struts when they get stretched horizontally.
Hope this helps someone!
i had this problem also and it seams to manifest only on specific languages and on iOS 7.0 , i had this issue when i want to underline the text in chinese, solved the problem with [ label sizeToFit] hope it will help ;)

Pretty self explanatory, see this image:
Steps to reproduce:
"Before" marks the view position in portrait orientation prior to autorotation.
Rotate the device to landscape.
Rotate back to portrait. "After" shows the view position after this return to portrait.
It appears that the height of the container view has been increased. Has anyone experienced this before? I'm sure there is some obscure setting that is slightly off.
Are you sure you've set auto resizing masks correctly? Maybe that's the issue
You say in the comments that this is happening on the iPhone 5. I had some problems positioning views on the iPhone 5, and these issues could not be fixed with autoResizingMask no matter what setting I tried. I eventually solved the problem by adding these two lines of code in viewDidLoad:
UIScreen *screen = [UIScreen mainScreen];
[self.view setFrame:[screen applicationFrame]];
Since your problem is on a rotation, you probably need these lines to be executed upon rotation rather than in viewDidLoad.
