UIDatePicker泄漏 [英] UIDatePicker leaks

问题描述

我似乎有一个泄漏的UIDatePicker。我已经注意到设置datePickerMode以显示日期和时间的内存泄漏。但是，我只是想显示日期。我相当确定这是一个框架泄漏，因为当我注释掉几个UIDatePicker属性分配时，泄漏就消失了。此代码泄漏1个CGColor对象，1个UIDeviceRGBColor对象：

  datePicker = [[UIDatePicker alloc] initWithFrame：[self detailViewRect]] ; 
 
 
 datePicker.datePickerMode = UIDatePickerModeDate; //设置这个
时泄漏CGColor datePicker.hidden = NO; 
 datePicker.timeZone = [NSTimeZone systemTimeZone]; // leaks UIDeviceRGBColor 
 datePicker.maximumDate = [NSDate date]; // leaks UIDeviceRGBColor 
 datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
  

通过评论仪器报告为违规行为，我没有泄漏：

  datePicker = [[UIDatePicker alloc] initWithFrame：[self detailViewRect]]; 
 
 //datePicker.datePickerMode = UIDatePickerModeDate; //设置这个
时泄漏CGColor datePicker.hidden = NO; 
 //datePicker.timeZone = [NSTimeZone systemTimeZone]; // leaks UIDeviceRGBColor 
 //datePicker.maximumDate = [NSDate date]; // leaks UIDeviceRGBColor 
 datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
  

如果没有至少设置日期模式，UIDatePicker是没有价值的。有没有人有解决方法？

解决方案

这种方法适用于我：

创建DatePicker xib而不是编程方法。然后，在属性检查器上，将模式设置为日期。

I appear to have a leaky UIDatePicker. I have noted memory leaks for setting the datePickerMode to show date and time. But, I'm only trying to display date. I'm fairly certain this is a framework leak because when I comment out several UIDatePicker property assignments, the leaks go away. This code leaks 1 CGColor object, and 1 UIDeviceRGBColor object:

datePicker = [[UIDatePicker alloc] initWithFrame:[self detailViewRect]];


datePicker.datePickerMode = UIDatePickerModeDate; //leaks CGColor when setting this
datePicker.hidden = NO;
datePicker.timeZone = [NSTimeZone systemTimeZone]; //leaks UIDeviceRGBColor
datePicker.maximumDate = [NSDate date];//leaks UIDeviceRGBColor
datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth;

By commenting the lines Instruments reported as offending, I get no leaks:

datePicker = [[UIDatePicker alloc] initWithFrame:[self detailViewRect]];

//datePicker.datePickerMode = UIDatePickerModeDate; //leaks CGColor when setting this
datePicker.hidden = NO;
//datePicker.timeZone = [NSTimeZone systemTimeZone]; //leaks UIDeviceRGBColor
//datePicker.maximumDate = [NSDate date];//leaks UIDeviceRGBColor
datePicker.autoresizingMask = UIViewAutoresizingFlexibleWidth;

Without at least date mode set, the UIDatePicker is worthless. Does anyone have a workaround?

解决方案

This approach worked for me:

Create the DatePicker in xib instead of the programmatic approach. Then, on the Attributes Inspector, set Mode to Date.
