UIView之常用方法

• 將一個(gè)視圖添加為子視圖，并使之在最上面顯示
  -(void)addSubView:(UIView *)view;
• 將指定子視圖移動(dòng)到頂部
  -(void)bringSubViewToFront:(UIView *)view;
• 將指定之視圖放到最下面
  -(void)sendSubViewToBack:(UIView *)view;
• 將指定視圖添加到subviews數(shù)組的index位置
  -(void)insertSubview:(UIView *)view atIndex:(NSInteger)index;
• 將指定視圖添加到指定子視圖下面
  -(void)insertSubview:(UIView *)view belowSubview:(UIView *)siblingSubview;
• 將指定視圖添加到指定子視圖上面
  -(void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview;
• 交換subviews數(shù)組中兩個(gè)位置的子視圖
  -(void)exchangeSubviewAtIndex:(NSInteger)index1 withSubviewAtIndex:(NSInteger)index2;
• 從父視圖中移除
  -(void)removeFromSuperview;
• 根據(jù)tag值獲取對(duì)應(yīng)的子孫控件
  -(UIView *)viewWithTag:(NSInteger)tag;
• 將視圖中點(diǎn)從自己的坐標(biāo)系轉(zhuǎn)換到指定的視圖坐標(biāo)系中
  -(CGPoint)convertPoint:(CGPoint)point toView:(UIView *)view;
• 將指定視圖中坐標(biāo)系內(nèi)的某點(diǎn)轉(zhuǎn)換到自己的坐標(biāo)系中
  -(CGPoint)convertPoint:(CGPoint)point fromView:(UIView *)view;
• 將視圖中矩形區(qū)域從自己的坐標(biāo)系轉(zhuǎn)換到指定的視圖坐標(biāo)系中
  -(CGRect)convertRect:(CGRect)rect toView:(UIView *)view;
• 將指定視圖中坐標(biāo)系內(nèi)的矩形區(qū)域轉(zhuǎn)換到自己的坐標(biāo)系中
  -(CGRect)convertRect:(CGRect)rect fromView:(UIView *)view;
• 刷新視圖,調(diào)用后自動(dòng)調(diào)用drawRect:(CGRect)rect
  -(void)setNeedsDisplay;

• 繼承自UIResponder用于響應(yīng)觸摸事件的方法

1.- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
2.- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
3.- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
4.- (void)touchesCancelled:(nullable NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;

以上方法需要自定義view重寫，若需要對(duì)觸摸點(diǎn)到判斷（使用）那么重寫方法時(shí)，在方法體內(nèi)首先獲取觸摸點(diǎn)：

1.UITouch *touch = [touches anyObject];
2.CGPoint point = [touch locationInView:self];

• 動(dòng)畫

1.// 首先需要設(shè)置動(dòng)畫頭，告訴編譯器下面是動(dòng)畫
2.[UIView beginAnimations:nil context:nil];
3.// 再設(shè)置動(dòng)畫執(zhí)行的配置、動(dòng)畫
4.[UIView setAnimationDuration:0.5];
5.[UIView setAnimationRepeatCount:2];
6.[UIView setAnimationDelay:3.0];
7.// balabala需要執(zhí)行的動(dòng)畫
8. ................
9.// 最后提交動(dòng)畫
10.[UIView commitAnimations];

• 使用block設(shè)置動(dòng)畫
  
  • 方法一
    +(void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations;
  • 方法二
    +(void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
  • 方法三
    + (void)animateWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^ __nullable)(BOOL finished))completion
