本文详细探讨了在iOS开发中如何使用UIView的Frame进行界面布局和交互。通过阅读，你将了解到Frame的重要属性及其在坐标系统中的应用，以及如何通过修改Frame实现视图动态调整。

#import <UIKit/UIKit.h>

@interface UIView (Frame)

@property (nonatomic,assign) CGFloat top;
@property (nonatomic,assign) CGFloat left;
@property (nonatomic,assign) CGFloat right;
@property (nonatomic,assign) CGFloat bottom;

@property (nonatomic,assign) CGFloat width;
@property (nonatomic,assign) CGFloat height;
@property (nonatomic,assign) CGSize  size;
@property (nonatomic,assign) CGPoint origin;

@property (nonatomic,assign) CGFloat centerX;
@property (nonatomic,assign) CGFloat centerY;

- (void)setMaskRadius:(float)radius;

@end

#import "UIView+Frame.h"

@implementation UIView (Frame)

- (void)setTop:(CGFloat)top{
    CGRect frame = self.frame;
    frame.origin.y = top;
    self.frame = frame;
}
- (CGFloat)top{
    return self.frame.origin.y;
}

- (void)setLeft:(CGFloat)left{
    CGRect frame = self.frame;
    frame.origin.x = left;
    self.frame = frame;
}
- (CGFloat)left{
