UIToolbar shows different color on ios 5.0 and ios

问题:

I have set tintcolor for my UIToolBar.It displays Correctly in ios 6.0 but it shows black color on ios 5.0 simulator. My code is here

originalBounds = mysearchBarBarItem.customView.bounds;
mySearchBar.bounds = CGRectMake(0,0,215,44);
myTopToolbar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]];
myTopToolbar.barStyle = UIBarStyleDefault;

mySearchBar.barStyle = UIBarStyleDefault;
mySearchBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]];

[myTopToolbar setItems:toolBarItemsArray animated:YES];

回答1:

I don't know if this can make a difference, but you could try to change the order in which you assign the style and color of the bar. Try:

myTopToolbar.barStyle = UIBarStyleDefault;   
myTopToolbar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]];

It's possible that assigning the style after changing the tintcolor resets the color.

EDIT

Why this would affect only ios5 and not ios6 I don't know.

回答2:

You can use UIAppearance (for iOS 5.0 and above) .

回答3:

Try to set color property

myTopToolbar.tintColor = [UIColor redColor]; 

If this works fine in both iOS6 and iOS5, then problem should be in image.

Edited Check this question

Try to do this in your app delegate implementation class this will change the toolBar and searchBar color throughout the application

for setting tint of searchbar

[[UISearchBar appearance] setTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]]];

OR

[[UISearchBar appearance] setTintColor:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1]];

for setting tint of toolbar

[[UIToolbar appearance] setTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]];

OR

[[UIToolbar appearance] setTintColor:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1]];

for setting background image

[[UIToolbar appearance] setBackgroundImage:[UIImage imageNamed:@"bgtoolbar.png"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
