UIView 확장

작은 도구 라 고 할 수 있 습 니 다. 여러분 의 이후 코드 속 도 를 향상 시 킬 수 있 습 니 다!효 과 는 다음 과 같 습 니 다:

self.view.frame.size.width
//    
self.width

저 희 는 UIView 확장 하나만 하면 돼 요.
UIView+Extension.h

#import 

@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) CGSize  size;
@property (nonatomic, assign) CGFloat centerX;
@property (nonatomic, assign) CGFloat centerY; 
@end

UIView+Extension.m

#import "UIView+Extension.h"

@implementation UIView (Extension)

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

- (CGFloat)x
{
    return self.frame.origin.x;
}

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

- (CGFloat)y
{
    return self.frame.origin.y;
}

- (void)setWidth:(CGFloat)width
{
    CGRect frame = self.frame;
    frame.size.width = width;
    self.frame = frame;
}

- (CGFloat)width
{
    return self.frame.size.width;
}

- (void)setHeight:(CGFloat)height
{
    CGRect frame = self.frame;
    frame.size.height = height;
    self.frame = frame;
}

- (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;
}

- (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

자, 효과 좀 봅 시다.

- (void)layoutSubviews {
//    [super layoutSubviews];
    
    //      frame
    int btnCount = (int)self.btnArray.count;
    CGFloat btnW = self.width / btnCount;
    CGFloat btnH = self.height;
    for (int i = 0; i < btnCount; i++){
        UIButton *btn = self.btnArray[i];
        btn.width = btnW;
        btn.height = btnH;
        btn.y = 0;
        btn.x = i *btnW;
    }
    
    int divideCount = (int)self.lineArray.count;
    for (int i = 0; i < divideCount; i++){
        UIImageView *divide = self.lineArray[i];
        divide.width = 1;
        divide.height = btnH;
        divide.centerX = (i + 1) *btnW;
        divide.centerY = btnH * 0.5;
    }
}

훨씬 편 하지 않 아 요?어린이 신발 들, UIView 확장 에 코드 를 복사 하면 됩 니 다!!
