iOS 7 사용자 정의 셀이 테이블보기에 표시되지 않습니다.

Question

제발 저와 함께 있으십시오. iOS 개발을 시작했습니다. 스토리 보드 을 스토리 보드 tableView에 표시하려고합니다. 나는 다음을했다.

내가

에 tableViewCell로 새로운 .xib을 만든 I는이에 대한 사용자 정의 클래스를 만들었습니다. .H 파일은 내 TableViewController.m에서 내가 가져온이

#import <UIKit/UIKit.h> 

@interface CustomTableCell : UITableViewCell 

@property (weak, nonatomic) IBOutlet UIImageView *thumbnailImageView; 
@property (weak, nonatomic) IBOutlet UILabel› *titleLabel; 

@end 

처럼 보이는 CustomTableCell.h 내가하지만, 10 행

이 구축 잘 보인다

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
    return 1; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return 10; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"CustomTableCell"; 
    CustomTableCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    if(cell == nil) 
    { 
     NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomTableCell" owner:self options:nil]; 
     cell = [nib objectAtIndex:0]; 
    } 

    cell.titleLabel.text ="test text"; 


    return cell; 
} 

을 위해 다음을 수행하고 때 프로젝트로드 아무것도 일어난다. 어떤 조언도 훌륭합니다.

cellForRowAtIndexPath 메서드에 중단 점을 배치했지만이 지점에 도달하지 않습니다. 여기 시뮬레이터

Answer 1

당신은 펜촉을로드하는 방법은 정말 구식 오래된이다. 펜촉을 등록하고 dequeueReusableCellWithIdentifier:forIndexPath:을 사용하면 훨씬 더 좋습니다 (iOS 6 이후).

사용자 지정 셀을 가져 오는 네 가지 방법 중 my explanation을 참조하십시오.

Answer 2

대리인 및 데이터 소스가 jQuery과의 스토리 보드에 설정되어 있는지 확인의 스크린 샷이다. 이렇게하면 각 행에 cellForRowAtIndexPath이 호출됩니다. 동일한 방법을 확인하기 위해 해당 방법에 NSLog 메시지를 넣을 수 있습니다.

또한 스토리 보드를 사용하고 있으므로 UITableView의 프로토 타입 셀을 살펴볼 수 있습니다. 그것들은 같은 일을하는 훨씬 쉬운 방법입니다 - 커스텀 셀을 가지고 UITableView를 생성하십시오.

여기에 스토리 보드의 jQuery과 내에서 프로토 타입의 세포를 사용하는 방법에 괜찮은 튜토리얼입니다 :

Answer 3

아주 기본적인 질문,하지만 당신은 표시되어야하는 세포 나타내는있는 tableview의 대리자 메서드를 구현? 위임 방법은 다음과 같다 :

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    //Return number of cells to display here 
    return 1; 
} 

Answer 4

당신은 당신의 .xib 파일을 등록해야합니다. 당신의 viewDidLoad 방법에서, 다음을 추가 :

는

[self.tableView registerNib:[UINib nibWithNibName:@"CustomTableCell" bundle:nil] 
    forCellReuseIdentifier:@"CustomTableCell"]; 

Answer 5

- (void) viewDidLoad { 

    [super viewDidLoad]; 

    UINib *cellNib = [UINib nibWithNibName:@"CustomTableCell" bundle:[NSBundle mainBundle]]; 
    [self.tableView registerNib:cellNib forCellReuseIdentifier:@"CustomTableCell"]; 

} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"CustomTableCell"; 
    CustomTableCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    if(cell == nil) 
    { 
     cell = [[CustomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
    } 

    cell.titleLabel.text ="test text"; 


    return cell; 
}
