小编Aru*_*run的帖子

我需要在将一些日期,我必须NSString以NSString这种格式:yyyy-MM-dd HH:mm:ss zzz 我写这篇文章的代码:

日期输入:日期---> 27/03/2012

-(NSString *)setDateStringFormat:(NSString *)date 
 {
     NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
     [formatter setDateFormat:@"dd/MM/yyyy"];
     [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
     //[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
     NSDate *dateFormatted = [formatter dateFromString:date];

     [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss zzz"];
     [formatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
 return [formatter stringFromDate:dateFormatted];
 }

输出:2012-03-27 00:00:00 GMT

你们都可以看到我得到了约会GMT而不是UTC 某个人有想法吗？

我有一个开发的项目,iOS 5.0现在我需要更新我的项目iOS 6.0.在这样做时,我xcode 4.5抛出的错误如下......

dyld: Library not loaded: @rpath/SenTestingKit.framework/Versions/A/SenTestingKit
  Referenced from: /Users/developer/Library/Application Support/iPhone Simulator/6.0/Applications/6EFF12B6-DA80-4DD8-B3CF-B217C5EA63DF/XxxxXxxx.app/xxxxXxxxXxx
  Reason: image not found

仍然它运行并在iOS 5设备中完美运行,我试图在iphone Simulator iOS 6.0它运行这个应用程序抛出错误...任何机构有任何想法...提前谢谢...

我的问题是我正在使用字典中的表数据源.这本词典中包含20多个元素.

我需要搜索字典中的元素,我需要将该元素滚动到可见单元格.

我的问题是我找到了元素,但它不在可见区域.我需要将其滚动到可见区域.

我怎样才能获得索引？

我试图淡出整个视图,但一个特定的subview,这将强调subview更清晰的外观.比方说,如果self.view有5个textfields和2个UIView作为subviews,我想1 UIView加以强调.是否有一种方法可以淡出/在整个自我中使用5 textfields和1 UIView而不触及强调UIView？

我已经尝试过使用方法了

+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion

如:

[UIView animateWithDuration:0.75
                 animations:^{
                     self.view.alpha = 0.5f;

                 }
                 completion:^(BOOL finished){self.view.layer.shouldRasterize = NO;}];

但是,似乎整个子视图都受到上面UIView动画的影响.任何建议或提示将不胜感激.

我有一个用户输入时间的选择器视图.当他们向下滚动到第23小时时,我希望小时0显示为下一个项目,并且要重新开始的序列.我怎样才能做到这一点？

这是我当前的选择器视图数据源:

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
    return 3; 
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
  NSArray *sectionContents = [[self dataForDatapickerRows] objectAtIndex:component];    
  NSInteger rows = [sectionContents count];     
  NSLog(@"component %d rows is: %d",component,rows);    
  return rows;  
}
- (NSString *)pickerView:(UIPickerView *)pickerView
             titleForRow:(NSInteger)row
            forComponent:(NSInteger)component {
  self.dataPickerInstance.backgroundColor=[UIColor whiteColor];       
  return ([[[self dataForDatapickerRows ]objectAtIndex:component] objectAtIndex:row]);
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    if(component==0)
    {
      [self setHou:(NSInteger*)[[[self dataForDatapickerRows ]objectAtIndex:component] objectAtIndex:row]];
    }
    else if(component==1)
    {
      [self setMinut:(NSInteger*)[[[self dataForDatapickerRows ]objectAtIndex:component] objectAtIndex:row]];
    }
    else if(component==2)
    {
      [self setSecon:(NSInteger*)[[[self dataForDatapickerRows ]objectAtIndex:component] objectAtIndex:row]];
    } …

我在将字符串数组转换为货币时遇到问题。

我创建了一个扩展currencyInputFormatting()。但是，逗号被放置在错误的位置。

这是我的代码：-

cell.balanceLabel.text? = (monthlyBalanceStringArray)[indexPath.row].currencyFormatting()

extension String {

    // formatting text for currency textField
    func currencyFormatting() -> String {

        var number: NSNumber!
        let formatter = NumberFormatter()
        formatter.numberStyle = .currency
        formatter.maximumFractionDigits = 2

        var amountWithPrefix = self

        let regex = try! NSRegularExpression(pattern: "[^0-9]", options: .caseInsensitive)
        amountWithPrefix = regex.stringByReplacingMatches(in: amountWithPrefix, options: NSRegularExpression.MatchingOptions(rawValue: 0), range: NSMakeRange(0, self.characters.count), withTemplate: "")

        let double = (amountWithPrefix as NSString).doubleValue
        number = NSNumber(value: (double))

        //    number = NSNumber(value: (double / 100))

        guard number != 0 …
