UIDatePicker 泄漏 [英] UIDatePicker leaks

问题描述

我似乎有一个泄漏的 UIDatePicker.我已经注意到用于设置 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，泄漏就会消失.这段代码泄漏了 1 个 CGColor 对象和 1 个 UIDeviceRGBColor 对象:

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;

通过评论 Instruments 报告的违规行，我没有发现任何泄漏:

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;

如果至少没有设置日期模式，UIDatePicker 就毫无价值.有没有人有解决方法?

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

推荐答案

这种方法对我有用:

在 xib 中创建 DatePicker 而不是编程方法.然后，在 Attributes Inspector 上，将 Mode 设置为 Date.

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