iOS开发基础UI控件之UIView

UIView继承自UIResponder

常用属性:userInteractionEnabled

        tag

        layer

常用方法:- (instancetype)initWithFrame:(CGRect)frame

UIView的扩展类(UIViewGeometry)

常用属性:frame

        bounds

        center

        transform

        autoresizingMask// simple resize. default is UIViewAutoresizingNone

        autoresizesSubviews// default is YES. if set, subviews are adjusted according to their autoresizingMask if self.bounds changes

常用方法:- (CGSize)sizeThatFits:(CGSize)size;// return 'best' size to fit given size. does not actually resize view. Default is return existing view size

        - (void)sizeToFit;// calls sizeThatFits: with current view bounds and changes bounds size.

UIView的扩展类(UIViewHierarchy)

常用属性:superview

        subviews

常用方法:

- (void)removeFromSuperview;

- (void)insertSubview:(UIView *)view atIndex:(NSInteger)index;

- (void)exchangeSubviewAtIndex:(NSInteger)index1 withSubviewAtIndex:(NSInteger)index2;

- (void)addSubview:(UIView *)view;

- (void)insertSubview:(UIView *)view belowSubview:(UIView *)siblingSubview;

- (void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview;

- (void)bringSubviewToFront:(UIView *)view;

- (void)sendSubviewToBack:(UIView *)view;

- (nullable__kindof UIView *)viewWithTag:(NSInteger)tag;// recursive search. includes self

- (void)layoutSubviews;   // override point. called by layoutIfNeeded automatically. As of iOS 6.0, when constraints-based layout is used the base implementation applies the constraints-based layout, otherwise it does nothing.

UIView的扩展类(UIViewRendering)

常用属性:clipsToBounds

        backgroundColor

        alpha

        hidden

        tintColor

常用方法:- (void)drawRect:(CGRect)rect;

UIView的扩展类(UIViewAnimation)

常用方法:

+ (void)beginAnimations:(nullableNSString *)animationID context:(nullablevoid *)context; // additional context info passed to will start/did stop selectors. begin/commit can be nested

+ (void)commitAnimations;// starts up any animations when the top level animation is commited

+ (void)setAnimationDuration:(NSTimeInterval)duration;             // default = 0.2

+ (void)setAnimationDelay:(NSTimeInterval)delay;                   // default = 0.0

+ (void)setAnimationStartDate:(NSDate *)startDate;                 // default = now ([NSDate date])

+ (void)setAnimationRepeatCount:(float)repeatCount;                // default = 0.0.  May be fractional

+ (void)setAnimationTransition:(UIViewAnimationTransition)transition forView:(UIView *)view cache:(BOOL)cache; // current limitation - only one per begin/commit block

UIView的扩展类(UIViewGestureRecognizers)

常用属性:gestureRecognizers

常用方法:- (void)addGestureRecognizer:(UIGestureRecognizer*)gestureRecognizerNS_AVAILABLE_IOS(3_2);

        - (void)removeGestureRecognizer:(UIGestureRecognizer*)gestureRecognizerNS_AVAILABLE_IOS(3_2);
