iphone应用开发教程（工具为Xcode6以上，使用storyboard）

https://developer.apple.com/library/ios/documentation/iphone/conceptual/iphone101/Articles/05_ConfiguringView.html

重点是学习交互事件，控件如何与代码关联，主要是拖动控件到.h 或.m文件。

.h文件内如如下：

#import <UIKit/UIKit.h>
 
@interface HelloWorldViewController : UIViewController <UITextFieldDelegate>
 
@property (weak, nonatomic) IBOutlet UITextField *textField;
@property (weak, nonatomic) IBOutlet UILabel *label;
@property (nonatomic, copy) NSString *userName;
 
- (IBAction)changeGreeting:(id)sender;
 
@end

.m文件内容如下：

The Implementation File: HelloWorldViewController.m
#import "HelloWorldViewController.h"
 
@implementation HelloWorldViewController
 
@synthesize textField=_textField;
@synthesize label=_label;
@synthesize userName=_userName;
 
 
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
    if (theTextField == self.textField) {
        [theTextField resignFirstResponder];
    }
    return YES;
}
 
- (IBAction)changeGreeting:(id)sender {
    self.userName = self.textField.text;
 
    NSString *nameString = self.userName;
    if ([nameString length] == 0) {
        nameString = @"World";
    }
    NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!", nameString];
    self.label.text = greeting;
}
@end
