我收到如下错误请帮助我 Advance Thanks, This is the error iam getting index 0 beyond bounds for empty array' *** First throw call stack:--->> 下面是我的代码:
-(void)retriveContactsFromAddressBook
{
//CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
if (addressBook!=nil)
{
NSArray *allContacts=(__bridge_transfer NSArray*)ABAddressBookCopyArrayOfAllPeople(addressBook);
NSUInteger i=0;
for ( i = 0; i<[allContacts count]; i++)
{
ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
NSString *lastName=(__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);
if (i==0) {
self.FirstName=[NSMutableArray arrayWithObject:firstName];
if (lastName==nil) {
self.LastName=[[NSMutableArray alloc]init];
} else {
self.LastName=[NSMutableArray arrayWithObject:lastName];
}
} else {
[self.FirstName addObject:firstName];
if (lastName==nil) {
[self.LastName addObject:@""];
} else {
[self.LastName addObject:lastName];
}
}
NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];
if (i==0) {
self.fullName=[NSMutableArray arrayWithObject:full];
} else {
[self.fullName addObject:full];
}
}
}
else
{
NSLog(@"Error Address book empty");
}
}
我遇到如下错误---->>>

最佳答案
-(void)retriveContactsFromAddressBook
{
//CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
self.LastName=[[NSMutableArray alloc]init];
self.FirstName=[[NSMutableArray alloc]init];
self.fullName=[NSMutableArray arrayWithObject:full];
if (addressBook!=nil)
{
NSArray *allContacts=(__bridge_transfer NSArray*)ABAddressBookCopyArrayOfAllPeople(addressBook);
NSUInteger i=0;
for ( i = 0; i<[allContacts count]; i++)
{
ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];
NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonFirstNameProperty);
NSString *lastName=(__bridge_transfer NSString*)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);
if (firstName == nil) {
[self.FirstName addObject:@""];
} else {
[self.FirstName addObject:firstName];
}
if (lastName==nil) {
[self.LastName addObject:@""];
} else {
[self.LastName addObject:lastName];
}
NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];
[self.fullName addObject:full];
}
}
else
{
NSLog(@"Error Address book empty");
}
}
像这样使用..
self.LastName=[[NSMutableArray alloc]init];
这一行就是问题所在.. 如果姓氏为 nil 你没有插入任何对象
NSString *full=[NSString stringWithFormat:@"%@ %@",[self.FirstName objectAtIndex:i],[self.LastName objectAtIndex:i]];
但在这一行 [self.LastName objectAtIndex:i]
中,您尝试从有问题的空数组中检索对象...
