阅读更多

ios8是main.storyboard
不是原来的用file's owner绑定了
连线全练到View Controller就行了

把autorelease设置成no



ViewController.h

#import 
@interface ViewController : UIViewController{
    IBOutlet UITableView *tableViewList;
    NSMutableArray *dataItems;
}
@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    dataItems=[[NSMutableArray alloc]initWithObjects:@"中国",@"美国",@"日本",nil];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
 numberOfRowsInSection:(NSInteger)section
{
    return [dataItems count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }
    NSUInteger row=[indexPath row];
    cell.textLabel.text=[dataItems objectAtIndex:row];
    return cell;
}
@end

加个自适应都输入文本输入框

#import 
@interface ViewController : UIViewController{
    IBOutlet UITableView *tableViewList;
    NSMutableArray *dataItems;
    IBOutlet UITextField *talktxt;
}
@end

#import "ViewController.h"
@interface ViewController ()

@end

    //dataItems=[[NSMutableArray alloc]initWithObjects:@"",@"",@"",@"",@"",@"",@"",@"",@"",@"",nil];
