处理键盘的ViewController基类
使用方法： 设置基类或者子类的isNeedHandleKeyboard成员变量为YES（默认NO），这个变量必须在BaseViewController的ViewDidLoad执行之前设置，因 为在BaseViewController的ViewDidLoad里面会执行检索代码，给所有输入框添加键盘关闭栏。
使用示例： @interface ViewController : BaseViewController
@end
@implementation ViewController
// --------- 使用纯代码构建ViewController的示例
-
(void) loadView { self.isNeedHandleKeyboard = YES; // 设置键盘处理
UIView *viewMain = [UIView new]; [viewMain setFrame:[UIScreen mainScreen].bounds]; [viewMain setBackgroundColor:RGBColor(255, 255, 255)]; [viewMain setUserInteractionEnabled:YES]; [self setView:viewMain];
int width = 200; int height = 40; int x = (CGRectGetWidth(viewMain.bounds) - width)/2; int y = CGRectGetHeight(viewMain.bounds) - height - 10; _textView = [UITextView new]; [_textView setFrame:CGRectMake(x, y, width, height)]; [_textView setBackgroundColor:RGBColor(244, 30, 30)]; [viewMain addSubview:_textView]; }
// --------- 使用storyboard构建ViewController的示例
- (instancetype) instanceForViewController { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"StoryboardName" bundle:nil]; ViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"]; [viewController setIsNeedHandleKeyboard:YES]; // 设置键盘处理 return viewController; }
