几句代码搞定计算每个控件的frame

程序员们都在因为计算每个控件的frame发愁, 因为控件frame是一个结构体类型, 不能直接进行修改, 需要..., 所以这里问我为大家写了一个类, 直接创建一个类, 进行拷贝就可以使用

• 这种方法的头文件最好写到pch 文件中, 因为pch 文件中, 因为这种计算控件的frame太常用了
• 这里对CGPoint几种不常用的点没有定义

• 创建一个UIVeiw+Extension的分类
• 在.h文件中需要定义属性
• 注意点: 在分类中定义的属性, 是不会生成带下划线的成员变量的

#import <UIKit/UIKit.h>

@interface UIView (Extension)

@property (nonatomic, assign) CGFloat x;
@property (nonatomic, assign) CGFloat y;
@property (nonatomic, assign) CGFloat width;
@property (nonatomic, assign) CGFloat height;
@property (nonatomic, assign) CGFloat centerX;
@property (nonatomic, assign) CGFloat centerY;
@property (nonatomic, assign) CGSize size;

@end

• 在.m文件中重写属性的getter 和setter方法, 对属性的frame进行修改

#import "UIView+Extension.h"

@implementation UIView (Extension)

-(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)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)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)width {

    return self.frame.size.width;
}

-(CGFloat)height {

    return self.frame.size.height;
}

-(void)setSize:(CGSize)size {
    CGRect frame = self.frame;
    frame.size = size;
    self.frame = frame;
    
}

-(CGSize)size {

    return self.frame.size;
}
@end
