收集常用的代碼塊是加快開發的有效途徑,收集的操作步驟這里不在贅述,僅僅貢獻上一些常用的功能性代碼

1、與高度和寬度有關的

 /*獲取導航欄高度*/
 public func getNavigationBarHeight() -> CGFloat {
  let navRect:CGRect! = self.navigationController?.navigationBar.frame
  return navRect.size.height
 }
 /*獲取標簽欄高度*/
 public func getTabBarHeight() -> CGFloat {
  let tabBarRect:CGRect! = self.tabBarController?.tabBar.frame
  return tabBarRect.size.height
 }
 /*獲取狀態欄高度*/
 public func getStatusBarHeight() -> CGFloat {
  let rectStatus:CGRect = UIApplication.shared.statusBarFrame
  return rectStatus.size.height
 }

 /*根據提供的字體大小,寬度獲取字文字的高度*/
 func getTextHeigh(textStr:String,font:UIFont,width:CGFloat) -> CGFloat {
  let normalText: NSString = textStr as NSString
  let size = CGSize(width: width, height: 10000)
  let dic:NSDictionary = NSDictionary(object: font, forKey: NSAttributedStringKey.font as NSCopying)
  let stringSize = normalText.boundingRect(with: size, options: .usesLineFragmentOrigin, attributes: dic as? [NSAttributedStringKey : Any], context:nil).size
  return stringSize.height
 }
 
 /*提供文字大小,控件高度,獲取到文字的寬度*/
 func getTexWidth(textStr:String,font:UIFont,height:CGFloat) -> CGFloat {
  let normalText: NSString = textStr as NSString
  let size = CGSize(width: 10000, height: height)
  let dic:NSDictionary = NSDictionary(object: font, forKey: NSAttributedStringKey.font as NSCopying)
  let stringSize = normalText.boundingRect(with: size, options: .usesLineFragmentOrigin, attributes: dic as? [NSAttributedStringKey : Any], context:nil).size
  return stringSize.width + 40
 }

 UIScreen.main.bounds.size.width // 屏幕寬度
 UIScreen.main.bounds.size.height // 屏幕高度


 /*UIFont的適配(創建UIFont的擴展)*/
+ (void)load {
 Method newMethod = class_getClassMethod([self class], @selector(adjustFont:));
 Method method = class_getClassMethod([self class], @selector(systemFontOfSize:));
 method_exchangeImplementations(newMethod, method);
}

+ (UIFont *)adjustFont:(CGFloat)fontSize {
 UIFont *newFont = nil;
 //BaseWidth 為設計圖的尺寸
 newFont = [UIFont adjustFont:fontSize * [UIScreen mainScreen].bounds.size.width / BaseWidth];
 return newFont;
}

 

2、處理類相關

/*十六進制顏色*/
func RGBColorFromHex(rgbValue: Int) -> (UIColor) {
 return UIColor(red: ((CGFloat)((rgbValue & 0xFF0000) >> 16)) / 255.0,
 green: ((CGFloat)((rgbValue & 0xFF00) >> 8)) / 255.0,
 blue: ((CGFloat)(rgbValue & 0xFF)) / 255.0,
 alpha: 1.0)
}

/*時間戳轉化成自定義時間格式*/
func getTimeWithTimeInterval(timeInterval:TimeInterval, dataFormart:String) -> String {
  let date:Date = Date(timeIntervalSince1970: timeInterval / 1000)
  let formatter:DateFormatter = DateFormatter.init()
  formatter.dateFormat = dataFormart
  let timeStr:String = formatter.string(from: date)
  return timeStr
 }

/*字符串MD5加密*/
- (NSString *)md5String:(NSString *)str
{
 if (!str) return nil;

 unsigned char result[CC_MD5_DIGEST_LENGTH];
 CC_MD5(cStr, (CC_LONG)strlen(cStr), result);
 NSMutableString *md5Str = [NSMutableString string];
 for (int i = 0; i < CC_MD5_DIGEST_LENGTH; ++i) {
  [md5Str appendFormat:@"%02x", result[i]];
 }
 return md5Str;
}

 NSMutableDictionary *signParams = [NSMutableDictionary dictionary];
 [signParams setObject:appid_key forKey:@"appid"];//微信appid 例如wxfb132134e5342
 [signParams setObject:noncestr_key forKey:@"noncestr"];//隨機字符串
 [signParams setObject:package_key forKey:@"package"];//擴展字段  參數為 Sign=WXPay
 [signParams setObject:partnerid_key forKey:@"partnerid"];//商戶賬號
 [signParams setObject:prepayid_key forKey:@"prepayid"];//此處為統一下單接口返回的預支付訂單號
 [signParams setObject:[NSString stringWithFormat:@"%u",timestamp_key] forKey:@"timestamp"];//時間戳
 
 NSMutableString *contentString  =[NSMutableString string];
 NSArray *keys = [signParams allKeys];
 NSArray *sortedArray = [keys sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
  return [obj1 compare:obj2 options:NSNumericSearch];
 }];
 for (NSString *categoryId in sortedArray) {
  if (![[signParams objectForKey:categoryId] isEqualToString:@""]
&& ![[signParams objectForKey:categoryId] isEqualToString:@"sign"]
&& ![[signParams objectForKey:categoryId] isEqualToString:@"key"]
)
  {
[contentString appendFormat:@"%@=%@&", categoryId, [signParams objectForKey:categoryId]];
  }
 }
 [contentString appendFormat:@"key=%@", @"utNO9LVL7LgMhfloAl8yO6ORrKIo2iky"];
 NSString *result = [self md5String:contentString];
 return result;
}

 if (result == nil) {
  block(kBarcodeFormatQRCode,nil);
  return;

}

/*swift執行一次的Dispatch_once函數*/
public extension DispatchQueue {
 private static var _onceTracker = [String]()
 public class func once(key: String, block:()->Void) {
  objc_sync_enter(self)
  defer { objc_sync_exit(self) }
  
  if _onceTracker.contains(key) {
return
  }
  _onceTracker.append(key)
  block()
 }
}

/*擴大按鈕響應區域(創建UIButton擴展)*/
static char topNameKey;

static char leftNameKey;
- (void)setEnlargeEdgeWithTop:(CGFloat) top right:(CGFloat) right bottom:(CGFloat) bottom left:(CGFloat) left {

  let orderDate:Date = Date.init(timeIntervalSince1970: timeInterval / 1000)
  let currentDate:Date = Date.init(timeIntervalSinceNow: 0)
  /*時間判斷*/
  if orderDate.compare(currentDate) == .orderedAscending {
isBefore = false
