вы можете создать подкласс UISearchBar
и переопределить метод layoutSubviews
:
- (void)layoutSubviews {
UITextField *searchField;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++) {
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
searchField = [self.subviews objectAtIndex:i];
}
}
if(!(searchField == nil)) {
searchField.textColor = [UIColor whiteColor];
[searchField setBackground: [UIImage imageNamed:@"yourImage.png"] ];
[searchField setBorderStyle:UITextBorderStyleNone];
}
[super layoutSubviews];
}
Также вы можете:
//to clear searchbar backgraound
- (void) clearSearchBarBg
{
for (UIView *subview in theSearchBar.subviews)
{
if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
[subview removeFromSuperview];
break;
}
}
}
//display showSearchButtonInitially in a keyboard
- (void)showSearchButtonInitially
{
UIView * subview;
NSArray * subviews = [theSearchBar subviews];
for(subview in subviews)
{
if( [subview isKindOfClass:[UITextField class]] )
{
NSLog(@"setEnablesReturnKeyAutomatically");
[((UITextField*)subview) setEnablesReturnKeyAutomatically:NO];
((UITextField*)subview).delegate=self;
[((UITextField*)subview) setEnabled:TRUE];
((UITextField*)subview).borderStyle = UITextBorderStyleNone;
break;
}
}
}
