常见控件布局-懒加载模版

1、UILabel

- (UILabel *)indexLbl{
    if (!_indexLbl) {
        _indexLbl = [UILabel new];
        _indexLbl.font = HYUniFont3;
        _indexLbl.textColor = HYUniTextcor1;
    }
    return _indexLbl;
}

1、UIImageView

- (UIImageView *)activityImageView{
    if (!_activityImageView) {
        _activityImageView = [UIImageView new];
        _activityImageView.contentMode = UIViewContentModeScaleAspectFill;
        _activityImageView.image = [UIImage imageNamed:@"hardware_img_update2"];
    }
    return _activityImageView;
}
//设置网络图片
NSString *urlStr = [HYHardwareUtil imageUrlByModel:deviceModel];
[self.deviceImageView sd_setImageWithURL:[NSURL URLWithString:urlStr]];

1、UIView

- (UIView *)lineView{
    if (!_lineView) {
        _lineView = [UIView new];
        _lineView.backgroundColor = [UIColor colorWithHexValue:0xE4E4E4];
        _lineView.layer.cornerRadius = 5.0f;
        _lineView.clipsToBounds = NO;
    }
    return _lineView;
}

1、UIButton

#import <SDWebImage/UIButton+WebCache.h>

- (UIButton *)managerFamilyBtn{
    if (!_managerFamilyBtn) {
        _managerFamilyBtn = [UIButton new];
        _managerFamilyBtn.backgroundColor = [UIColor whiteColor];
        _managerFamilyBtn.tag = 101;
        [_managerFamilyBtn setImage:[UIImage imageNamed:@"nav_icon_set_black_nor"] forState:UIControlStateNormal];
        [_managerFamilyBtn setTitle:@"家庭管理" forState:UIControlStateNormal];
_managerFamilyBtn.imageView.contentMode = UIViewContentModeScaleAspectFit;
        [_managerFamilyBtn.titleLabel setFont:HYHwUniFont17];
        [_managerFamilyBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [_managerFamilyBtn addTarget:self action:@selector(buttonOnclick:) forControlEvents:UIControlEventTouchUpInside];
        _managerFamilyBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
        _managerFamilyBtn.imageEdgeInsets = UIEdgeInsetsMake(0, 16, 0, 0);
        _managerFamilyBtn.titleEdgeInsets = UIEdgeInsetsMake(0, 22, 0, 0);
_managerFamilyBtn.layer.cornerRadius = 4.0;
_managerFamilyBtn.layer.masksToBounds = YES;
    }
    return _managerFamilyBtn;
}
//设置网络图片
[_iconBtn sd_setImageWithURL:imgurl forState:UIControlStateNormal placeholderImage:[UIImage imageNamed:normalImage] options:SDWebImageRefreshCached];
