第一次写，不知道咋弄呢。先放个 UIView的Category 试试
下面的是 .h代码
#import <UIKit/UIKit.h>
@interface UIView (UIView_Category)
@property (nonatomic, assign) CGFloat x;
@property (nonatomic, assign) CGFloat y;
@property (nonatomic, assign) CGFloat centerX;
@property (nonatomic, assign) CGFloat centerY;
@property (nonatomic, assign) CGFloat width;
@property (nonatomic, assign) CGFloat height;
@property (nonatomic, assign) CGSize size;
@property (nonatomic, assign) CGPoint origin;
@property (nonatomic, assign) CGFloat minX;
@property (nonatomic, assign) CGFloat minY;
@property (nonatomic, assign) CGFloat maxX;
@property (nonatomic, assign) CGFloat maxY;
-(void)setMaskRadius:(float)radius;
@end
下面的是 .m代码
#import "UIView+Category.h"
@implementation UIView (UIView_Category)
- (void)setX:(CGFloat)x
{
CGRect frame = self.frame;
frame.origin.x = x;
self.frame = frame;
}
- (void)setY:(CGFloat)y
{
CGRect frame = self.frame;
frame.origin.y = y;
self.frame = frame;
}
- (CGFloat)x
{
return self.frame.origin.x;
}
- (CGFloat)y
{
return self.frame.origin.y;
}
- (void)setCenterX:(CGFloat)centerX
{
CGPoint center = self.center;
center.x = centerX;
self.center = center;
}
- (CGFloat)centerX
{
return self.center.x;
}
- (void)setCenterY:(CGFloat)centerY
{
CGPoint center = self.center;
center.y = centerY;
self.center = center;
}
- (CGFloat)centerY
{
return self.center.y;
}
- (void)setWidth:(CGFloat)width
{
CGRect frame = self.frame;
frame.size.width = width;
self.frame = frame;
}
- (void)setHeight:(CGFloat)height
{
CGRect frame = self.frame;
frame.size.height = height;
self.frame = frame;
}
- (CGFloat)height
{
return self.frame.size.height;
}
- (CGFloat)width
{
return self.frame.size.width;
}
- (void)setSize:(CGSize)size
{
CGRect frame = self.frame;
frame.size = size;
self.frame = frame;
}
- (CGSize)size
{
return self.frame.size;
}
- (void)setOrigin:(CGPoint)origin
{
CGRect frame = self.frame;
frame.origin = origin;
self.frame = frame;
}
- (CGPoint)origin
{
return self.frame.origin;
}
- (void)setMinX:(CGFloat)minX{
self.minX = self.x;
}
- (CGFloat)minX{
return CGRectGetMinX(self.frame);
}
- (void)setMinY:(CGFloat)minY{
self.maxY = self.y;
}
- (CGFloat)minY{
return CGRectGetMinY(self.frame);
}
- (void)setMaxX:(CGFloat)maxX{
self.maxX = self.x +self.width;
}
- (CGFloat)maxX{
return CGRectGetMaxX(self.frame);
}
- (void)setMaxY:(CGFloat)maxY{
self.maxY = self.y + self.height;
}
- (CGFloat)maxY{
return CGRectGetMaxY(self.frame);
}
-(void)setMaskRadius:(float)radius{
self.layer.masksToBounds = YES;
self.layer.cornerRadius = radius;
}
@end
