以下是我用来展示- (IBAction)takePhoto:(UIButton *)sender {
if (![UIImagePickerController
isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertController *alert = [UIAlertController
alertControllerWithTitle:NSLocalizedString(@"Error", nil)
message:NSLocalizedString(@"Device has no camera", nil)
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *ok =
[UIAlertAction actionWithTitle:NSLocalizedString(@"OK", nil)
style:UIAlertActionStyleDefault
handler:nil];
[alert addAction:ok];
[self presentViewController:alert animated:YES completion:nil];
} else {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.videoQuality = UIImagePickerControllerQualityTypeMedium;
[self presentViewController:picker animated:YES completion:NULL];
}
}
的代码:
UIButton
目前我运行此方法(例如点击:parent has_many :kids
:kid has_many :schools
@parent = Parent(parent_params)
@parent = HTTParty.post("http://localhost:3001/parents/import",
:body => { :parent_id => @parent.id,
:terms_accepted => @parent.terms_accepted,
:email => @parent.email,
:kids => {
@parent.kid.school.name => @parent.kid.school_name,
@parent.kid.age => @parent.kid.age
}
}.to_json,
:headers => { 'Content-Type' => 'application/json' } )
)我可以在乐器中看到这一点:
如果我换成Cycles&根:
因此,如果我将鼠标悬停在第一次泄漏上,按下弹出的箭头,我就明白了:
如果我为这个方法打开堆栈跟踪,我会看到:
所以主要是系统调用。同样适用于其他泄漏,只是系统调用......所以这是一个bug还是?如果我几次打开和关闭图像选择器,我会得到更多泄漏,更多......
有人注意到了吗?
答案 0 :(得分:1)
你需要使UIImagePickerController * picker成为一个强大的属性。因此,该应用程序具有对该选择器的全局引用,您将能够将其解除。
