UIView里面的UITableView无法像UITextField一样按预期工作

Question

好吧，大家好，这是问题所在。我加载一个UIView内的UITableView，它不是显示两个文本框：

.H：

#import <UIKit/UIKit.h> 

@interface LoginViewController : UIViewController <UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate> { 

    UITableView *loginTableView; 
    UITextField *username; 
    UITextField *password; 

} 

@property UITableView *loginTableView; 
@property UITextField *username; 
@property UITextField *password; 

@end 

.M：

#import <QuartzCore/QuartzCore.h> 
#import "LoginViewController.h" 

@interface LoginViewController() 

@end 

@implementation LoginViewController 

@synthesize loginTableView, username, password; 

- (void)viewDidLoad { 

    [super viewDidLoad]; 

    // Make rounded corners view 
    [self.view.layer setCornerRadius:4.0]; 
    [self.view.layer setMasksToBounds:YES]; 
    self.view.layer.opaque = NO; 
    self.view.backgroundColor = [UIColor whiteColor]; 

    // Add login table view to main view 
    loginTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)]; 
    loginTableView.delegate = self; 
    loginTableView.dataSource = self; 
    [self.view addSubview:loginTableView]; 

} 

- (void)didReceiveMemoryWarning { 

    [super didReceiveMemoryWarning]; 

} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ 

    return 2; 

} 

- (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    UITableViewCell *cell = [table dequeueReusableCellWithIdentifier:@"Cell"]; 

    if(cell == nil) { 
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"]; 
    } 
    if (indexPath.row == 0) { 
     username = [[UITextField alloc] initWithFrame:CGRectMake(5, 0, 280, 21)]; 
     username.placeholder = @"Username"; 
     username.autocorrectionType = UITextAutocorrectionTypeNo; 
     [username setClearButtonMode:UITextFieldViewModeWhileEditing]; 
     cell.accessoryView = username; 
    } 
    if (indexPath.row == 1) { 
     password = [[UITextField alloc] initWithFrame:CGRectMake(5, 0, 280, 21)]; 
     password.placeholder = @"Password"; 
     password.secureTextEntry = YES; 
     password.autocorrectionType = UITextAutocorrectionTypeNo; 
     [password setClearButtonMode:UITextFieldViewModeWhileEditing]; 
     cell.accessoryView = password; 
    } 

    username.delegate = self; 
    password.delegate = self; 

    [loginTableView addSubview:username]; 
    [loginTableView addSubview:password]; 

    cell.selectionStyle = UITableViewCellSelectionStyleNone; 
    return cell; 

} 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ 

    return 1; 

} 

@end 

任何人都可以请告诉我，我什么做错了？

Answer 1

它看起来就像是增加了文本框在tableview中，而不是实际的细胞

[loginTableView addSubview:username]; //you're saying to add it to the table 

另外，您要添加的username两次
