A summary of common property methods for IOS UIView _ios

The following example code gives you a detailed introduction to the common property methods for iOS UIView, as shown in the following code:

Uiview:uiresponder/** Initializes a UI control/(ID) initWithFrame by a frame: (CGRect) frame; YES: Can interact with the user @property (nonatomic,getter=isuserinteractionenabled) BOOL userinteractionenabled;        A tag of the default is YES//control (the parent control can find the corresponding child control by tag) @property (nonatomic) nsinteger tag;
The default is 0//layer (which can be used to set rounded corners effect \ Shadow effect) @property (Nonatomic,readonly,retain) Calayer *layer;
@interface UIView (uiviewgeometry)//Position and dimensions (in the upper-left corner of the parent control as the coordinate origin (0, 0)) @property (nonatomic) cgrect frame;
Position and size (in the upper-left corner of the coordinate origin (0, 0)) @property (nonatomic) cgrect bounds;   
Midpoint (in the upper-left corner of the parent control as the coordinate origin (0, 0)) @property (nonatomic) Cgpoint Center;  Deformation properties (pan \ Zoom \ Rotate) @property (nonatomic) Cgaffinetransform transform; Default is cgaffinetransformidentity/YES: Multi-Touch @property (nonatomic,getter=ismultipletouchenabled) BOOL supported  multipletouchenabled;
The default is NO @end @interface uiview (Uiviewhierarchy)//Parent control @property (nonatomic,readonly) UIView *superview; Child controls (the newly added control defaults to the Subviews array, and the newly added control defaultsare shown on the top top top) @property (nonatomic,readonly,copy) Nsarray *subviews;
Gets the window @property (nonatomic,readonly) UIWindow *window where the current control is located;
Removes a control from the parent control-(void) Removefromsuperview;
Add a child control (you can insert a child control into the subviews array in the position of index)-(void) Insertsubview: (UIView *) View Atindex: (nsinteger) index;
Swap the position of the child control in the Subviews array-(void) Exchangesubviewatindex: (Nsinteger) index1 Withsubviewatindex: (Nsinteger) Index2;
Add a child control (the newly added control defaults to the Subviews array, and the newly added control defaults to the top \ Top)-(void) Addsubview: (UIView *) view;
Add a child control view (blocked under Siblingsubview)-(void) Insertsubview: (UIView *) View Belowsubview: (UIView *) Siblingsubview;
Add a child control view (covered above siblingsubview)-(void) Insertsubview: (UIView *) View Abovesubview: (UIView *) Siblingsubview;
Pull one of the child controls to the top (top) to display-(void) Bringsubviewtofront: (UIView *) view;
Pull one of the child controls to the bottom (bottommost) to display-(void) Sendsubviewtoback: (UIView *) view;
The/** system is automatically invoked (left to subclass to implement) **/-(void) Didaddsubview: (UIView *) Subview;
-(void) Willremovesubview: (UIView *) Subview; -(void) Willmovetosuperview: (UIView *) NewsupeRview;
-(void) Didmovetosuperview;
-(void) Willmovetowindow: (UIWindow *) NewWindow;
-(void) Didmovetowindow; The/** system automatically invokes **///is a child control of the view or child control (whether it is a descendant of view)-(BOOL) Isdescendantofview: (UIView *) view;
 Returns YES for self.   The corresponding child control (or child control) can be obtained by tag-(UIView *) Viewwithtag: (nsinteger) tag; Recursive search. Includes self/** system automatic invocation (left to subclass to implement) when the **///control's frame changes, it is invoked, where the layout child control is overridden, and the location and size of the placement sub-controls are overridden//The Write method is rewritten and must be called [Super Layoutsubviews]
;
-(void) layoutsubviews;
@end @interface UIView (uiviewrendering)/YES: Content that is outside the bounds of the control is clipped @property (nonatomic) BOOL clipstobounds; Background color @property (nonatomic,copy) Uicolor *backgroundcolor;           Default is nil//transparency (0.0~1.0) @property (nonatomic) cgfloat Alpha;           Default is 1.0/YES: Opaque No: Transparent @property (nonatomic,getter=isopaque) BOOL opaque;
 Default is yes/Yes: Hide NO: Displays @property (Nonatomic,getter=ishidden) BOOL hidden; Content mode @property (nonatomic) Uiviewcontentmode conTentmode; Default is Uiviewcontentmodescaletofill @end//Animation @interface UIView (uiviewanimationwithblocks) + (void) animatewithdu Ration: (nstimeinterval) Duration delay: (nstimeinterval) Delay options: (uiviewanimationoptions) Options animations: (
