在我的应用程序中，有一个选择照片按钮，当点击按钮时，它应该拍摄 iPhone 照片并只显示图像而不显示视频。使用我的代码，它显示图像和视频。只显示图像的方法是什么.寻求帮助，感谢advanace。下面是我的代码：

#import <AssetsLibrary/AssetsLibrary.h>
-(void)choosePhotoFromExistingImages
{
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary])
{
    controller = [[UIImagePickerController alloc] init];
    controller.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    controller.allowsEditing = NO;
    controller.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: UIImagePickerControllerSourceTypePhotoLibrary];
    controller.delegate = self;
    [self.navigationController presentViewController: controller animated: YES completion: nil];
}

}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
if (picker==controller){
    [self.navigationController dismissViewControllerAnimated: YES completion: nil];
    UIImage *image1 = [info valueForKey: UIImagePickerControllerOriginalImage];

    CGFloat compression = 0.9f;
    CGFloat maxCompression = 0.1f;
    int maxFileSize = 250*1024;

   NSData *imageData = UIImageJPEGRepresentation(image1, compression);

    while ([imageData length] > maxFileSize …

我想UITableView在点击时显示UITextView.键盘不应该显示.问题在于点击UITextView两者UITableView和键盘都显示出来.我只希望显示表格视图.我想显示从Web服务获取的数据,UITextView这是不可编辑的.按下导航栏中的编辑按钮,点击时UITextView,UITableView应该弹出而不是键盘.

我的代码如下:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{

if([text isEqualToString:@"\n"]) {
    [textView resignFirstResponder];
    return NO;
}

return YES;
}

-(void)textViewDidBeginEditing:(UITextView *)textView{


[self.view endEditing:YES];

tableVw=[[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320, 500)];
tableVw.dataSource=self;
tableVw.delegate=self;


[self.view addSubview:tableVw];

 }
 -(void)viewDidLoad{

 [super viewDidLoad];

 txtVwDescription=[[UITextView alloc]initWithFrame:CGRectMake(10, 270, 300,stringSize.height+10)];
 txtVwDescription.backgroundColor=[UIColor clearColor];
txtVwDescription.layer.cornerRadius=5;
txtVwDescription.backgroundColor=[UIColor colorWithRed:0.662745 green:0.662745 blue:0.662745 alpha:0.3];

[txtVwDescription setFont:[UIFont systemFontOfSize:13.0]];
txtVwDescription.contentInset=UIEdgeInsetsMake(0, 0, 0, 0);
[txtVwDescription setUserInteractionEnabled:NO];
txtVwDescription.editable=NO;
txtVwDescription.delegate=self;
[self.view addSubview:txtVwDescription];
}

 -(void)edit{
 [txtVwDescription setUserInteractionEnabled:YES];
 txtVwDescription.editable=NO; …
