补充5：swift3.0以上 tableviewcell分割线显示不全解决方案
-
方案1：UITableViewCell.separatorInset和UIView.layoutMargins
if tableView.responds(to:#selector(setter: UITableViewCell.separatorInset)) {
tableView.separatorInset = UIEdgeInsets.zero
}
if tableView.responds(to:#selector(setter: UIView.layoutMargins)) {
tableView.layoutMargins = UIEdgeInsets.zero
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
if cell.responds(to: #selector(setter: UITableViewCell.separatorInset)) {
cell.separatorInset = UIEdgeInsets.zero
}
if cell.responds(to:#selector(setter: UIView.layoutMargins)) {
cell.layoutMargins = UIEdgeInsets.zero
}
}
-
方案2：draw(_ rect: CGRect)，通过在底部绘制颜色
// MARK: - 系统方法
override func awakeFromNib() {
super.awakeFromNib()
// 记得要设置contentView.backgroundColor为clear，否则颜色会被它挡住了
self.contentView.backgroundColor = UIColor.clear
}
override func draw(_ rect: CGRect) {
let context = UIGraphicsGetCurrentContext()!
context.setFillColor(UIColor.white.cgColor)
context.fill(rect)
context.setFillColor(UIColor(white: 0.9, alpha: 1.0).cgColor)
context.fill(CGRect(x: 0, y: rect.size.height - 3, width:rect.size.width, height: 3))
}
-
方案3：朋友教的，重写frame,高度-x,露出背景色
override var frame: CGRect {
didSet {
var tmpFrame : CGRect = super.frame
tmpFrame.size.height -= 3
super.frame = tmpFrame
}
}
-
总结：方法一和方法二需要去掉系统的分割线tb.separatorStyle = UITableViewCellSeparatorStyle.none效果更佳
OC方法改变Tableview分割线的边距
// tableView设置:
//1.调整(iOS7以上)表格分隔线边距
if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
self.tableView.separatorInset = UIEdgeInsetsZero;
}
// 2.调整(iOS8以上)view边距(或者在cell中设置preservesSuperviewLayoutMargins,二者等效)
if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
self.tableView.layoutMargins = UIEdgeInsetsZero;
}
// cell 设置:
cell.preservesSuperviewLayoutMargins = NO;
[cell setLayoutMargins:UIEdgeInsetsZero];
-
补充6：Swift3.0纯代码添加约束 可供参考
- 给需要设置约束的视图禁用autoresizing，禁用父视图autoresizing对子控件无效
// 说明
/*
constraintWithItem:需要设置约束的view
attribute:需要设置约束的位置
relatedBy:约束的条件
toItem:约束依赖目标
attribute:依赖目标约束位置
multiplier:配置系数
constant:额外需要添加的长度
*/
/*
计算公式:redView.attribute = self.view.attribute * multiplier + constant;
其中:＝符号取决于relatedBy:参数
typedef NS_ENUM(NSInteger, NSLayoutRelation) {
NSLayoutRelationLessThanOrEqual = -1, 小于等于
NSLayoutRelationEqual = 0, 等于
NSLayoutRelationGreaterThanOrEqual = 1, 大于等于
};
*/
tableView.translatesAutoresizingMaskIntoConstraints = false
let leftCon = NSLayoutConstraint(item: tableView, attribute: NSLayoutAttribute.left, relatedBy: NSLayoutRelation.equal, toItem: self.view, attribute: NSLayoutAttribute.left, multiplier: 1.0, constant: 0)
let rightCon = NSLayoutConstraint(item: tableView, attribute: .right, relatedBy: NSLayoutRelation.equal, toItem: self.view, attribute: .right, multiplier: 1.0, constant: 0)
let topCon = NSLayoutConstraint(item: tableView, attribute: .top, relatedBy: .equal, toItem: self.view, attribute: .top, multiplier: 1.0, constant: 0)
let bottomCon = NSLayoutConstraint(item: tableView, attribute: .bottom, relatedBy: .equal
, toItem: self.view, attribute: .bottom, multiplier: 1.0, constant: 0)
self.view.addConstraints([leftCon,rightCon,topCon,bottomCon])

cons += NSLayoutConstraint.constraints(withVisualFormat: "V:|-0-[tableView]-0-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: ["tableView": tableView])
view.addConstraints(cons)
-
eg1： "V:|-20-[redView(==50)]"
- 解释：redView(==50)是什么意思？V是代表垂直方向，垂直方向也就是高度，说明redView他的高度是50，同理如果是H开头呢，就是代表宽度 。-20-又是什么意思呢？距离父控件上边为20。
-
eg2："V:[redView]-20-[blueView(==50)]"
- 解释：同理blueView他的高度是50，V是代表垂直方向，而且blueView距离redView垂直距离为20
-
eg3:
let layout_frameView = ["frameView":frameView,"superView":self.view]
var frameView_constraints = NSLayoutConstraint.constraintsWithVisualFormat("H:[frameView(300.)]-(<=1)-[superView]", options: NSLayoutFormatOptions.AlignAllCenterY, metrics: nil, views: layout_frameView)
frameView_constraints = NSLayoutConstraint.constraintsWithVisualFormat("V:[frameView(200.0)]-(<=1)-[superView]", options: NSLayoutFormatOptions.AlignAllCenterX, metrics: nil, views: layout_frameView)
view.addConstraints(frameView_constraints)
- 解释：frameView宽度300和高度为200并且居中显示
-
补充7：Swift3.0控件存在屏幕底部，当键盘出现，控件出现在键盘上方
类似这个
// MARK:- 系统方法
override func viewDidLoad() {
super.viewDidLoad()
// 1.添加并且布局
view.addSubview(toolBar)
toolBar.snp_makeConstraints { (make) -> Void in
make.bottom.left.right.equalTo(view)
make.height.equalTo(44)
}
// 2.监听键盘尺寸的改变的通知

}
/// 监听键盘尺寸的改变的方法

UIKeyboardAnimationDurationUserInfoKey = "0.4";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 365}, {375, 302}}";
}
*/
let duration = (noti.userInfo![UIKeyboardAnimationDurationUserInfoKey]! as AnyObject).doubleValue
let offsetY = (noti.userInfo![UIKeyboardFrameEndUserInfoKey]! as AnyObject).cgRectValue.origin.y - MGScreenH
// toolBar: 是要挨着键盘的控件
toolBar.snp.updateConstraints { (make) -> Void in
make.bottom.equalTo(view.snp.bottom).offset(offsetY)
}
let CurveValue = noti.userInfo![UIKeyboardAnimationCurveUserInfoKey]! as! Int
UIView.animate(withDuration: duration!, delay: 0, options: UIViewAnimationOptions(rawValue: 0), animations: { () -> Void in
UIView.setAnimationCurve(UIViewAnimationCurve.init(rawValue: CurveValue)!)
self.view.layoutIfNeeded()
}, completion: nil)
}
-
补充8：Swift3.0tableView右边标题按钮兰的研究,通过KVC和Runtime可以改变颜色，系统API默认有提供接口sectionIndexColor和sectionIndexBackgroundColor。其他功能还没有研究到，要做这个其他功能自定义比较合适。（比如选中文字有颜色...等）
func test() {
let indexView = tableView.value(forKeyPath: "_index")
as? UIView
indexView?.setValue(UIColor.darkGray, forKey: "_indexColor")
indexView?.setValue(UIColor.randomColor(), forKey: "_indexTrackingBackgroundColor")
indexView?.setValue(UIColor.randomColor(), forKey: "_indexBackgroundColor")
let sel = NSSelectorFromString("endTrackingWithTouch:withEvent:")
let _ = indexView?.perform(sel)
self.mg_GetMethodAndPropertiesFromClass(cls: NSClassFromString("UITableViewIndex")!)
(NSClassFromString("UITableViewIndex") as! UIView.Type).init()
}
-
补充9：Swift3.0 URL的encode和decode

// MARK: - encoding 系统API

let originalString = str as CFString
let charactersToBeEscaped = "!*'();:@&=+$,/?%#[]" as CFString //":/?&=;+!@#$()',*" //转意符号

return result as String
}
/**

func stringByURLDecode() -> String {
if self.removingPercentEncoding != nil {
return self.removingPercentEncoding!
} else {
let en: CFStringEncoding = CFStringConvertNSStringEncodingToEncoding(String.Encoding.utf8.rawValue)
var decoded: String = self.replacingOccurrences(of: "+", with: " ")
decoded = (CFURLCreateStringByReplacingPercentEscapesUsingEncoding(nil, (decoded as CFString),nil, en) as String)
return decoded

}
}

补充10：In-Call Status Bar的监听及视图位置改变调整
//监听状态栏的改变
MGNotificationCenter.addObserver(self, selector: #selector(self.statusBarChange(noti:)), name: NSNotification.Name.UIApplicationWillChangeStatusBarFrame, object: nil)
-
通知方法，执行一些相应的的操作(感觉主要对frame布局的UI影响较大)
@objc fileprivate func statusBarChange(noti: Notification) {
// 获取变化参数
let rectValue: NSValue? = (noti.userInfo?[UIApplicationStatusBarFrameUserInfoKey] as? NSValue)
let statusRect: CGRect? = rectValue?.cgRectValue
let statusFrame: CGRect = view.convert(statusRect!, from: MGKeyWindow)
let statusHeight: CGFloat = statusFrame.size.height - 20
// 需要修改的控件，举个🌰：比如下面这个
if statusHeight == 0 {
settingBtn.frame = CGRect(x: 15, y: MGScreenH-64-44, width: 60, height: 44)
} else {
settingBtn.frame = CGRect(x: 15, y: MGScreenH-64-44-20, width: 60, height: 44)
}

补充16：iOS判断过期或者想要延时x天后才执行某方法（Swift3.x和Objective-c）
-
登录是否过期（连续5天未登录App,就重新登录)Objective-c（iOS判断过期）

你的这个UIDeviceOrientationIsLandscape(deviceOrientation)，deviceOrientation是参数，有系统的一个方法(屏幕发生变化)传进来的，UIDeviceOrientationIsLandscape(deviceOrientation)这个判断是放在那个方法里，用来判断屏幕旋转后此时是横屏还是竖屏的
