Я вложил в UISearchBar субкласс, чтобы настроить пользовательское изображение для кнопки результатов поиска следующим образом (файл .m):
#import "CustomUISearchBar.h"
#define RGB(r, g, b) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1]
#define RGBA(r, g, b, a) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a]
@implementation GipUISearchBar
- (void)layoutSubviews
{
UITextField *searchField = nil;
UIView *backGround = nil;
UIButton *cancelButton = nil;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++)
{
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]])
{
searchField = [self.subviews objectAtIndex:i];
}
else if ([[self.subviews objectAtIndex:i] isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
backGround = [self.subviews objectAtIndex:i];
}
else if ([[self.subviews objectAtIndex:i] isKindOfClass:[UIButton class]])
{
cancelButton = [self.subviews objectAtIndex:i]; [cancelButton setTintColor:RGB(22.0,38.0,111.0)];
}
}
if(!(searchField == nil))
{
searchField.layer.cornerRadius=15.0f;
searchField.layer.masksToBounds=YES;
searchField.layer.borderColor = [RGB(26.0,141.0,223.0)CGColor];
searchField.layer.borderWidth = 2.0f;
UIImage *glassImage = [UIImage imageNamed: @"search_icon.png"];
UIImageView *iView = [[UIImageView alloc] initWithImage:glassImage];
searchField.leftView = iView;
[iView release];
UIImage *historyImage = [UIImage imageNamed:@"history_button.png"];
UIButton *historyButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[historyButton setBackgroundImage:historyImage forState:UIControlStateNormal];
[historyButton setBackgroundImage:historyImage forState:UIControlStateSelected];
[historyButton setBackgroundImage:historyImage forState:UIControlStateDisabled];
[historyButton setBackgroundImage:historyImage forState:UIControlStateHighlighted];
historyButton.frame = CGRectMake(0,
0,
historyImage.size.width-3,
historyImage.size.height-3);
historyButton.layer.borderColor = [RGBA(0.0,0.0,0.0,0.0)CGColor];
historyButton.layer.borderWidth = 0.0f;
searchField.rightView = historyButton;
}
if (!(backGround == nil))
[backGround removeFromSuperview];
[super layoutSubviews];
}
Проблема в том, что когда я касаюсь внутри панели поиска, и она меняет размеры, я вижу, как эта кнопка перемещается слева направо. Как я могу отключить это поведение?
