推荐一个Button 弹起PickerView的源码,也可以作为工具类使用。
利用inputView 做键盘弹起动画。该如何做呢?
1.继承UIView
2.重写属性&方法
@property (readwrite) UIView *inputView; @property (readwrite) UIView *inputAccessoryView; - (BOOL)isUserInteractionEnabled { return YES; } - (BOOL)canBecomeFirstResponder { return YES; }
3.添加TapGesture
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(touchAction)]; [tap setNumberOfTouchesRequired:1]; [tap setNumberOfTapsRequired:1]; [self addGestureRecognizer:tap];
4.实现方法touchAction
