Xcode快捷键:
格式化代码:
control + i (Editor-Structure-Re indent)
移动代码:
alt+command+[ (Editor-Structure-Move Line Up)
alt+command+] (Editor-Structure-Move Line Down)
从当前位置删除到分隔符:
例如: 如下代码, 我们想把dataArray改为resultArray:
let group = dataArray[section]
通常做法是将鼠标放到data后面, 然后按delete多次删除data, 其实删除的这一步可以按住alt+delete; 这样就会删除当前鼠标指针到前面分隔符之间的字符.
向后删除:
fn + delete; 只是Mac系统的功能, 也就是说, 所有的编辑界面都可以用, 不仅限于Xcode
创建桥接文件:
因为目前QMUI还没有Swift版本, 是OC版本, 而我们是Swift项目, 所有需要创建桥接文件, 方法是在项目里面创建一个OC文件, 会自动弹出提示询问是否添加桥接文件, 选择是就行了
#import <QMUIKit/QMUIKit.h>
使用:
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = UIColor.systemPink
view.addSubview(showMoreButtonView)
}
@objc func onPrimaryClick(){
print("点击了按钮")
}
//懒加载

let result = QMUIButton(frame: CGRect(x: 50, y: 100, width: 200, height: 45))
result.adjustsButtonWhenHighlighted = true//自动调整高亮效果
result.titleLabel?.font = UIFont.systemFont(ofSize: 15)
result.setTitleColor(.white, for: .normal)

result.layer.cornerRadius = 5
result.setTitle("从底部显示更多弹窗按钮", for: .normal)
result.addTarget(self, action: #selector(onPrimaryClick), for: .touchUpInside)
return result
}()
}

SnapKit -- 设置页
在SettingView.swift中, 封装组件:
/// 设置itemVIew
class SettingView: UIView {
//重写构造方法
init(){
super.init(frame: CGRect.zero)
innerInit()//定义公共的init方法
}
//重写可视化的init方法
required init?(coder: NSCoder) {
super.init(coder: coder)
innerInit()//定义公共的init方法
}
func innerInit() {
backgroundColor = .white
addSubview(iconView)
addSubview(titleView)
addSubview(moreIconView)
}
/// 当视图加入父视图时 / 当视图从父视图移除时调用
override func didMoveToSuperview() {
super.didMoveToSuperview()
//添加约束
iconView.snp.makeConstraints { make in
make.left.equalToSuperview().offset(16)
make.centerY.equalToSuperview()
make.width.equalTo(20)
make.height.equalTo(20)
}
titleView.snp.makeConstraints { make in
make.left.equalTo(iconView.snp.right).offset(16)
make.centerY.equalToSuperview()
//不用设置宽高, 根据内容自动宽高
}
moreIconView.snp.makeConstraints { make in
make.right.equalToSuperview().offset(-16)
make.centerY.equalToSuperview()
make.width.equalTo(20)
make.height.equalTo(20)
}
}
/// 左侧图标
lazy var iconView: UIImageView = {
let result = UIImageView()
result.image = UIImage(named: "Setting")

/// 标题
lazy var titleView: UILabel = {

return result
}()
/// 右侧图标
lazy var moreIconView: UIImageView = {
let result = UIImageView()

在SettingController.swift中, 使用组件:

self.view.backgroundColor = .systemGray
//-------设置item
self.view.addSubview(settingView)
self.view.addSubview(collectionView)
//-----设置约束
settingView.snp.makeConstraints { make in
make.left.equalToSuperview()
make.right.equalToSuperview()
if #available(iOS 11.0, *) {
make.top.equalTo(self.view.safeAreaLayoutGuide.snp.top).offset(16)
} else {
// Fallback on earlier versions
}
make.height.equalTo(55)
}
collectionView.snp.makeConstraints { make in
make.left.equalToSuperview()
make.right.equalToSuperview()
make.top.equalTo(self.settingView.snp.bottom).offset(0.5)
make.height.equalTo(55)
}
}
/// 设置Item
lazy var settingView: SettingView = {
let result = SettingView()
result.titleView.text = "设置"
//设置点击事件
result.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(onSettingClick(recognizer:))))
return result
}()
/// 收藏Item
lazy var collectionView: SettingView = {
let result = SettingView()
result.titleView.text = "收藏"
return result
}()
@objc func onSettingClick(recognizer:UITapGestureRecognizer) {
print("点击了设置界面的一个item")
}
}
