I've spent a whole day trying to change the colour of a UIBarButtonItem and now i'm thinking it is an iOS 11 bug unless someone can tell me it's by design.
I can change the colour of the text by using this code
[self.refreshButton setTitleTextAttributes:#{NSForegroundColorAttributeName: [UIColor orangeColor]} forState:UIControlStateNormal];
If I add the code to the viewWillAppear:animated function it works fine, however if you add it to viewDidAppear:animated it does not work.
It seems to work on the iOS 9 simulator, but not iOS 11.
Has something changed in this regard in iOS 11?
If all you want to do is change the title color of your UIBarButtonItem you can set the tintColor property instead of setTitleTextAttributes:. If you want all of your UIBarButtonItems to have the same title color you can set the tintColor of your tool/navigation bar.
I had the same issue on iOS11 but needed to set the font by setTitleTextAttributes. Unfortunately this does also not work by appearance. The only solution I found was to create new BarButtonItems as copy of the old ones and then set them as navigationItem.rightBarButtonItems.
For reference for other users having the same issue.
This Stack Overflow answer may explain why the method doesn't work.
An improper setting of UIControlState() may be the problem.
I'm using Xcode 6.1.1
Is it possible to set the background colour in code for the selected/highlighted state for UIButton? - Not a background image!
I'm using ID's for colors (e.g. #"theme.brand.primary") that are linked to a json file i.e. .plist file
I've done it for setTitleColor UIControlStateHighlighted which works fine... example code:
[button setTitleColor:[config getColour:#"button.text.pressed-state"] forState:UIControlStateHighlighted];
However I want the colour of the button to change not the title.
There is no option for setBackgroundColor:forState: ???
Does anyone know if theres a simple way to do this?
Can you not just check for highlighted?
if (myButton.highlighted) {
myButton setBackgroundColor.......
}
I have open-sourced a class, STAButton, to fill this functionality hole. Available under the MIT license. Works for iOS 7+ (I have not tested with older iOS versions).
I am trying to change the button background image. This code is working fine with IOS 6/7. After I upgrade to IOS 7.1 suddenly it is stop working.
[monday setBackgroundImage:[UIImage imageNamed:#"toggleTopRight"] forState:UIControlStateNormal];
BWT: the image is ok, because this code is being called in view will appear and this ok there ... when i press on the button that need to change the setBackgroundImage it's not working.
This is a bug on 7.1 SDK and Xcode 5.1.
The workaround is to call [UIButton setNeedsLayout] after your changes.
That should do the trick.
I had the same problem. I finally found out that setting a button's (background) image doesn't work on iOS 7.1, if the button is disabled.
Not sure if this fixes your problem, but it was mine. Calling setNeedsLayout didn't help in my case, unfortunately. What you can do as a workaround is either to override UIButton or to add a category that contains a method like the following to set an image:
- (void)setBackgroundImage:(UIImage *)img forButtonState:(UIControlState)state
BOOL shouldEnable = self.enabled;
self.enabled = YES;
[self setBackgroundImage:img forState:state];
self.enabled = shouldEnable;
}
Filed a bug report for this issue (16497031).
For me it's the foreground image that covered the background image. So make your foreground image transparent then the background image will show. Setting background image actually works fine now.
I am using the below code to get a shadow to button title label.
theCuLabel.titleLabel.shadowColor=[UIColor blackColor];
theCuLabel.titleLabel.shadowOffset=CGSizeMake(-3.0,2.5);
In IOS 6 its working properly like below
But in IOS 7 its not working as expected like below
I didn't find solution for this, can any one tell me the solution or any update in IOS 7 that happened for this.
Thanks in Advance...
[button setTitleShadowColor:[UIColor blackColor] forState:UIControlStateNormal];
this is the correct method to set the shadow color for a UIButton.
I have tried this and is working in all versions.
Is it possible to have a segmented control on an iOS 7 device show up as the iOS 6 version of the control?
We really aren't ready for an interface redesign and the new flat control doesn't jive with the rest of our UI. It would definitely be best to keep the iOS 6 style for now, if possible.
To clarify, I am compiling using the iOS 6.1 Base SDK. I am aware that this is the "obvious" answer to my question, but it does not work. Most other UI elements will show up with iOS 6 styling by doing this, but like the UIAlertView and UIActionSheet, the UISegmentedControl does not. However, unlike the UIAlertView and UIActionSheet, UISegmentedControls do not feel like a "system" item; they should be able to display in iOS 6 mode.
Edit: I thought it would be helpful if I finally included a picture with this (probably should have done this from the start). However, the answer I provided did fix the issue. Also, in retrospect, it looks like this might be the iOS 6 style after all, it's just displaying so wrong that it appears like iOS 7 style.
I manage to do a pretty good job of solving this problem by setting all the attributes manually, but it is not quite perfect.
This is what I ended up doing:
- (void)fixSegmentedControlForiOS7
{
NSInteger deviceVersion = [[UIDevice currentDevice] systemVersion].integerValue;
if(deviceVersion < 7) // If this is not an iOS 7 device, we do not need to perform these customizations.
return;
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont boldSystemFontOfSize:12], UITextAttributeFont,
[UIColor whiteColor], UITextAttributeTextColor,
nil];
[self.segmentedControl setTitleTextAttributes:attributes forState:UIControlStateNormal];
NSDictionary *highlightedAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor];
[self.segmentedControl setTitleTextAttributes:highlightedAttributes forState:UIControlStateHighlighted];
self.segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
self.segmentedControl.tintColor = [UIColor colorWithRed:49.0 / 256.0 green:148.0 / 256.0 blue:208.0 / 256.0 alpha:1];
}
To fix images assigned with InterfaceBuilder use this code:
- (void)fixImagesOfSegmentedControlForiOS7
{
NSInteger deviceVersion = [[UIDevice currentDevice] systemVersion].integerValue;
if(deviceVersion < 7) // If this is not an iOS 7 device, we do not need to perform these customizations.
return;
for(int i=0;i<toSegmentedControl.numberOfSegments;i++)
{
UIImage* img = [toSegmentedControl imageForSegmentAtIndex:i];
UIImage* goodImg = [img imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
// clone image with different rendering mode
[toSegmentedControl setImage:goodImg forSegmentAtIndex:i];
}
}
I just ran into this problem today myself. The app I'm working on updating is quite old, and still uses xib files, so I do not know if this works on storyboards or not. As others suggested above, you still need to use the iOS 6.1 SDK, but this alone is not enough. After performing the following steps, I was able to get the old UISegmentedControl appearance back:
Open the interface builder document in question
Go to the file inspector (first inspector tab; has a document icon)
Under the "Interface Builder Document" section, change "Opens in" to Xcode 4.6
I do believe this is a bug, and I would not be surprised if there isn't a workaround for UISegmentedControl instances created in code. I'm guessing this is somewhat related to the deprecation of the segmentedControlStyle property in iOS 7 (see https://developer.apple.com/library/ios/documentation/uikit/reference/UISegmentedControl_Class/DeprecationAppendix/AppendixADeprecatedAPI.html#//apple_ref/occ/instp/UISegmentedControl/segmentedControlStyle).
Hope this helps someone out there.
If you save the iPhoneOS6.1.sdk file from the previous version of XCode and add it to Xcode 5 in the same path you can then build an app against the 6.1 SDK so that when it runs on 7 everything is like 6. Linking against iOS7 SDK tells iOS to make everything look like iOS7 if possible. Essentially then you have an iOS6 app but building it with XCode 5.
If you use images on any of your UISegmentedControl segments, you'll need to add some code to set those properly on iOS 7, otherwise they'll be used as a template image and the selected segment will be a cutout of the segment's background.
UISegmentedControl under iOS 7 interprets its images as being in rendering mode UIImageRenderingModeAlwaysTemplate unless otherwise specified. I had to use -[UIImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] on each segment's image for iOS 7 to achieve the previous behavior.
Either you could:
Not update your app at all for iOS7 until you're ready to make some UI changes. Apps compiled against the iOS6 SDK will run in iOS6 Compatibility mode on iOS7 and will look exactly the same as they did in iOS6.
Apply custom background, separator, etc images to your segmented controls that mimic the look they had in iOS6.
Yes, it is possible if you recreate the control by your own. Create a fake segmented control that looks like and work like one.
In my app, I have set the Segmented control to "Bar" style. It renders in ios6 style on my ios7 iphone5 (whoa, 5,6,7). However, the text inside the segments are cut and have the three dots "..." added, no matter how wide the view is.
So the ios6 segmented control rendering in ios7 seems really buggy
Is it possible? Not really...
You could make your own custom segmented control.
Or you could use the UIAppearance proxy to customise your segmented control with images but then it's your responsibility to make it look like it was on iOS 6.
