在手机中各个角度的位置
分享到微信再次分享出现图片不显示的问题
os上分享出来时是调用了微信的app分享sdk，已经通过验证和相关配置，所以第一次正常显示图片和标题等，这里的分享源头是APP。
然而分享到微信后，二次分享时，分享源头变成了微信客户端，这时微信是需要验证页面的jssdk分享配置的，验证成功才会为你添加图片和标题等。
所以解决办法是，在分享的页面里添加对微信jssdk分享接口的调用，添加相关配置参数，并且在微信公众号后台里配置好页面的所在的域名为安全域名才行。
设置距离今天18年前的date
NSDate *currentDate = currentDate = [NSDate date];
NSCalendar *calendar = nil; if ([UIDevice currentDevice].systemVersion.doubleValue >= 8.0)
{
calendar = [NSCalendar calendarWithIdentifier:NSCalendarIdentifierGregorian];
} else {
calendar = [NSCalendar currentCalendar];
}
NSDateComponents *dateComponents = [calendar components:NSYearCalendarUnit fromDate:currentDate];
[date Components setYear:-18];
NSDate *newdate = [calendar dateByAddingComponents:dateComponents toDate:currentDate options:0];
周几
- (NSString *)calculateWeek:(NSDate *)date{
//计算week数
NSCalendar * myCalendar = [NSCalendar currentCalendar];
myCalendar.timeZone = [NSTimeZone systemTimeZone];
NSInteger week = [[myCalendar components:NSWeekdayCalendarUnit fromDate:date] weekday];
NSLog(@"week : %zd",week);
switch (week) {
case 1: { return @"周日"; }
case 2: { return @"周一"; }
case 3: { return @"周二"; }
case 4: { return @"周三"; }
case 5: { return @"周四"; }
case 6: { return @"周五"; }
case 7: { return @"周六"; }

按钮文字对齐方式
Button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;//左对齐(UIControlContentHorizontalAlignment、CenterUIControlContentHorizontalAlignmentFill、UIControlContentHorizontalAlignmentRight)
Button.contentVerticalAlignment = UIControlContentVerticalAlignmentBottom;//底部对其(UIControlContentVerticalAlignmentCenter、UIControlContentVerticalAlignmentFill、UIControlContentVerticalAlignmentTop)
