Question

我有以下代码供图片选择器使用：

- (void)actionSheet:(UIActionSheet *)popup clickedButtonAtIndex:(NSInteger)buttonIndex {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;

switch (popup.tag) {
    case 1: {
        switch (buttonIndex) {
            case 0:
                picker.sourceType = UIImagePickerControllerSourceTypeCamera;
                [self presentViewController:picker animated:YES completion:NULL];
                break;
            case 1:
                picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
                [self presentViewController:picker animated:YES completion:NULL];
                break

同时出现以下错误：

[__NSCFArray pointSize]: unrecognized selector sent to instance 0x6a5e640

终止调用抛出异常

Answer 1

它有点旧，但最近我遇到了类似的问题。检查你是否有某个地方

NSFontAttributeName: "Some string"

这应该替换为

NSFontAttributeName: UIFont(name: "Some-font", size: yourSize)

这对我有用。

- (IBAction)OnClickbutton:(id)sender {

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle: nil
                                                         delegate: (id)self
                                                cancelButtonTitle: @"Cancel"
                                           destructiveButtonTitle: nil
                                                otherButtonTitles: @"Take a new photo", @"Choose from existing", nil];
[actionSheet showInView:self.view];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex];

if  ([buttonTitle isEqualToString:@"Take a new photo"]) {
    [self takeNewPhotoFromCamera];
}
if ([buttonTitle isEqualToString:@"Choose from existing"]) {
    [self choosePhotoFromExistingImages];
}


}

- (void)takeNewPhotoFromCamera
{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.editing = YES;
imagePickerController.delegate = (id)self;

[self presentViewController:imagePickerController animated:YES completion:nil];

}

 -(void)choosePhotoFromExistingImages
 {
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary])
{
    UIImagePickerController *controller = [[UIImagePickerController alloc] init];
    controller.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    controller.allowsEditing = NO;
    controller.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypePhotoLibrary];
    controller.delegate = (id)self;
    controller.navigationBar.barStyle = UIBarStyleBlackTranslucent; // Or whatever style.

    [self.navigationController presentViewController: controller animated: YES completion: nil];
}
}

UiimagepickerView：在呈现uiimagepickerview时应用程序崩溃了？
