I have this Tab Bar working properly on iOS 8 but not on iOS 7 can someone point me in the right direction, i use a JSON file to configure my UITabBar when it loads the first screen.
Do I have to use different images for iOS 7??
It is possible to change the size of de Button to avoid the behavior??
iOS 8:
iOS 7:
This is the code I use to load the images:
- (void)createTabBar
{
tabController = [self.storyboard instantiateViewControllerWithIdentifier:@"cCustomTabController"];
dValue = [dConfiguration objectForKey:@"Buttons"];
NSMutableArray *aControllers = [[NSMutableArray alloc] init];
int i = 0;
for (NSString* sProperty in dValue) {
NSString* d = @"Details";
NetworkStatus internetStatus = [_reachabilityInfo currentReachabilityStatus];
NSData *itemData = Nil;
if (internetStatus != NotReachable)
itemData = [util getSpecificJsonData:[sProperty valueForKeyPath:@"Item"]];
if(itemData != nil){
UIStoryboard *aStoryboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:[NSBundle mainBundle]];
UIViewController *vcCustom = [aStoryboard instantiateViewControllerWithIdentifier:[util getControllerName:[sProperty valueForKeyPath:@"ViewController"]]];
UIImage *imageBtn = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"Image"] andRetrina:[sProperty valueForKeyPath:@"ImageRetina"]]];
UIImage *imageBtnPress = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"ImageHeighlighted"] andRetrina:[sProperty valueForKeyPath:@"ImageRetinaHeighlighted"]]];
UITabBarItem *tab = [[UITabBarItem alloc] initWithTitle:[sProperty valueForKeyPath:@"Title"] image:imageBtn selectedImage:imageBtnPress];
UIImage * iSelected = imageBtnPress;
iSelected = [iSelected imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
[tab setSelectedImage:iSelected];
tab.tag = i;
if([[sProperty valueForKeyPath:@"Title"] isEqualToString:@"Notificaciones"])
tab.badgeValue=[sProperty valueForKeyPath:@"Badge"];
[vcCustom setTabBarItem:tab];
[vcCustom setTitle:[sProperty valueForKeyPath:@"Title"]];
[aControllers insertObject:navigationController atIndex:i];
i++;
}
else
{
UIStoryboard *aStoryboard = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:[NSBundle mainBundle]];
UIViewController *vcCustom = [aStoryboard instantiateViewControllerWithIdentifier:[util getControllerName:[sProperty valueForKeyPath:@"ViewController"]]];
UIImage *imageBtn = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"Image"] andRetrina:[sProperty valueForKeyPath:@"ImageRetina"]]];
UIImage *imageBtnPress = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"ImageHeighlighted"] andRetrina:[sProperty valueForKeyPath:@"ImageRetinaHeighlighted"]]];
UITabBarItem *tab = [[UITabBarItem alloc] initWithTitle:[sProperty valueForKeyPath:@"Title"] image:imageBtn selectedImage:imageBtnPress];
UIImage * iSelected = imageBtnPress;
iSelected = [iSelected imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
[tab setSelectedImage:iSelected];
tab.tag = i;
if([[sProperty valueForKeyPath:@"Title"] isEqualToString:@"Notificaciones"])
tab.badgeValue=[sProperty valueForKeyPath:@"Badge"];
[vcCustom setTabBarItem:tab];
[vcCustom setTitle:[sProperty valueForKeyPath:@"Title"]];
UINavigationController *navigationController = [[cCustomNavigationController alloc] initWithRootViewController:vcCustom];
[aControllers insertObject:navigationController atIndex:i];
i++;
}
}
tabController.delegate = self;
tabController.viewControllers = aControllers;
tabController.tabBar.tintColor = [UIColor blackColor];
}
Thanks in advance.
I have changed in my code this 2 lines:
UIImage *imageBtn = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"Image"] andRetrina:[sProperty valueForKeyPath:@"ImageRetina"]]];
UIImage *imageBtnPress = [UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"ImageHeighlighted"] andRetrina:[sProperty valueForKeyPath:@"ImageRetinaHeighlighted"]]];
For this 2:
UIImage *imageBtn = [self changeImageSize:[UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"Image"] andRetrina:[sProperty valueForKeyPath:@"ImageRetina"]]] scaledToSize:CGSizeMake(30, 30)];
UIImage *imageBtnPress = [self changeImageSize:[UIImage imageNamed:[util getImageName:[sProperty valueForKeyPath:@"ImageHeighlighted"] andRetrina:[sProperty valueForKeyPath:@"ImageRetinaHeighlighted"]]] scaledToSize:CGSizeMake(30, 30)];
And added this function to change the size of the image:
- (UIImage *)changeImageSize:(UIImage *)image scaledToSize:(CGSize)newSize {
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
[image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
I don't know if this is correct but for me is working.
Thanks to all and happy coding.
