iPad UIImagePicker 相机教程

发布于 2024-11-19 15:34:15 字数 152 浏览 2 评论 0原文

我在 google 上寻找完整的教程，并寻找有关使用 UIImagePicker 从相机获取图片以及从 iPad 2 上的库或相机胶卷获取图片的完整示例堆栈。

我找到了代码片段，说明只需添加 PopOverController中，但未能成功实施。

提前致谢。

我这样做我检测 iPhone 或 iPad 以及弹出窗口中显示的 (self.album.bounds) 只是您希望弹出窗口箭头出现在这种情况下 self.album 是触发以下操作的按钮

-(IBAction)selectPicture:(id)sender {

NSLog(@"Image is not set");

// Create image picker controller
thePicker = [[UIImagePickerController alloc] init];

// Set source to the camer roll;
thePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

// Delegate to self
thePicker.delegate = self;

//Allow editing of image NO
thePicker.allowsEditing = NO;


if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {


[self presentModalViewController:thePicker animated:YES];

}

else{

    popover = [[UIPopoverController alloc]initWithContentViewController:thePicker];
    [popover presentPopoverFromRect:self.album.bounds inView:self.album permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
    popover = popover;

}

}

I do it like this I detect if iPhone or iPad and in the popover where it says (self.album.bounds) is just were you want the popover arrow to appear in this case self.album is the button that fires the below action

-(IBAction)selectPicture:(id)sender {

NSLog(@"Image is not set");

// Create image picker controller
thePicker = [[UIImagePickerController alloc] init];

// Set source to the camer roll;
thePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

// Delegate to self
thePicker.delegate = self;

//Allow editing of image NO
thePicker.allowsEditing = NO;


if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {


[self presentModalViewController:thePicker animated:YES];

}

else{

    popover = [[UIPopoverController alloc]initWithContentViewController:thePicker];
    [popover presentPopoverFromRect:self.album.bounds inView:self.album permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
    popover = popover;

}

}
