iOS 修改SearchBar的Textfiled的Cursor游标颜色和字体样式和大小；Disable输入框

因为Search Bar的游标颜色和Tint颜色是统一的，如果要想将游标的颜色设置为其他颜色，则需要到textfiled内部去修改，对于字体也是同样。

实现代码：

- (void)setSearchBarTextfiled:(UISearchBar *)searchBar{
    for (UIView *view in searchBar.subviews){
        for (id subview in view.subviews){
            if ( [subview isKindOfClass:[UITextField class]] ){
                [(UITextField *)subview setTintColor:[UIColor grayColor]];
                [(UITextField *)subview setFont:[UIFont fontWithName:GENERAL_FONT size:13]];
                return;
            }
        }
    }
}

如果要实现用户不能输入到搜索框中，则需要是textfiled的输入失效：

一种方法是对于整个Searchbar设置Disable，但是这样如果有Scope Button等其他组件的话，也会连同失效：

[searchBar setUserInteractionEnabled:NO];

实现代码：

- (void)enableTextInput:(UISearchBar *)searchBar{
    for (UIView *view in searchBar.subviews){
        for (id subview in view.subviews){
            if ( [subview isKindOfClass:[UITextField class]] ){
                [subview setEnabled:YES];
                return;
            }
        }
    }
}

- (void)disableTextInput:(UISearchBar *)searchBar{
    for (UIView *view in searchBar.subviews){
        for (id subview in view.subviews){
            if ( [subview isKindOfClass:[UITextField class]] ){
                [subview setEnabled:NO];
                return;
            }
        }
    }
}
