我想按字母顺序显示手机联系人以及桌面视图中的图片。在桌面视图中显示联系人图像以及联系人姓名
我设法以正确的顺序显示联系人姓名，但无法以正确的顺序显示图像。
我一直在尝试这些几天，但不能成功。
我知道如何排序数组，但不知道如何排序图像数据。
请帮帮我吧。
这里是我的演示代码：用于显示在细胞图像
NSArray *sortedFirstNames;
- (void)getPersonDetails
{
CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
if (addressBook != nil)
{
NSLog(@"Succesful.");
NSArray *allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
NSUInteger i = 0;
NSMutableArray *firstNames = [[NSMutableArray alloc] init];
NSMutableArray *firstimages = [[NSMutableArray alloc] init];
for (i = 0; i < [allContacts count]; i++)
{
Person *person = [[Person alloc] init];
ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);
NSString *fullName;
if (lastName == nil)
{
fullName = [NSString stringWithFormat:@"%@", firstName];
[firstNames addObject: fullName];
}
else if(firstName ==nil)
{
fullName = [NSString stringWithFormat:@"%@", lastName];
[firstNames addObject: fullName];
}
else
{
fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName];
[firstNames addObject: fullName];
}
person.firstName = firstName;
person.lastName = lastName;
person.fullName = fullName;
//email
imgdata=(__bridge NSData*)ABPersonCopyImageDataWithFormat(contactPerson, kABPersonImageFormatThumbnail);
NSLog(@"newstris%@",imageStr);
if(imgdata==nil)
{
}
else
{
[firstimages addObject:imgdata];
}
[self.tableData addObject:person];
}
sortedFirstNames = [firstNames sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
}
CFRelease(addressBook);
}
代码：
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
dispatch_async(queue, ^{
UIImage *image1;
// cell.imageView.frame = CGRectMake(0, 0, 50, 50);
if (person.imgdata==nil) {
image1=[UIImage imageNamed:@"default_profile_pic.jpg"];
}
else
{
image1 = [UIImage imageWithData:person.imgdata];
}
UIImageView *imageView = [[UIImageView alloc] initWithImage:image1];
imageView.frame = CGRectMake(6.5, 6.5, 45., 45.);
dispatch_sync(dispatch_get_main_queue(), ^{
[cell addSubview:imageView];
});
});
谢谢..
感谢您的回答，我已经做到了，但图像没有显示相关的名称。我想要图像以及那里的名称在阿尔法（A-Z） –
您确定图像数据在cellForRowAtIndexPath中不为空吗？ –
@VarunVishnoi：你使用过财产吗？ –
