先看效果图：
需求：在绿色框内实现图片的均匀布局。
思路：
1.先获取绿色框的宽度
2.再获取所有图片的宽度
3.获取图片间的间距（（绿色框的宽度-所有图片的宽度）／（图片数-1））
4.进行布局
代码：
CGFloat allImageW = 0.0f;
NSInteger picCount = 5; // 图片数
CGFloat w = self.view.frame.size.width;
for (NSInteger i = 0; i < picCount; i ++) {
UIImageView * picView = [[UIImageView alloc] init];
[bottomView addSubview:picView];
picView.image = [UIImage imageNamed:@"hotArea"];
[self.imageArr addObject:picView];
CGFloat imageW = picView.image.size.width;
allImageW += imageW;
w -= picView.image.size.width;
}
// 图片间距
CGFloat gap = (w - 20) / (picCount - 1);
CGFloat foreImagesW = 0.0f;
for (NSInteger i = 0; i < picCount; i ++) {
UIImageView * picView = self.imageArr[i];
CGFloat left = i * gap + foreImagesW;
[picView mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(bottomView.mas_left).offset(left);
make.centerY.equalTo(bottomView.mas_centerY);
}];
foreImagesW += picView.image.size.width;
}
