可以重寫UISearchBar，然后調用layoutSubviews這個方法。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

- (void)layoutSubviews { ????UITextField *searchField; ????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]; ????????} ????} ????if(!(searchField == nil)) { ????????searchField.textColor = [UIColor whiteColor]; ????????[searchField.leftView setHidden:YES]; ????????[searchField setBackground: [UIImage imageNamed:@"SearchBarBackground.png"] ]; ????????[searchField setBorderStyle:UITextBorderStyleNone]; ????} ????? ????[super layoutSubviews]; }
