自定义导航栏按钮

首先，写一个类，继承于UIButton。

头文件：
Ios代码
#import <Foundation/Foundation.h>

@inte易做图ce BlueButton : UIButton {

}

- (id)init;

@end

3 Ios代码

6 @implementation BlueButton

8 - (id)init {
9   if(self = [super init]) {
10     self.frame = CGRectMake(0, 0, 49.0, 30.0);
11     self.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
12     self.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
13
14     UIImage *image = [UIImage imageNamed:@"blueButton.jpg"];
15     UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:15.0 topCapHeight:0.0];
16     [self setBackgroundImage:stretchImage forState:UIControlStateNormal];
17
18     self.backgroundColor = [UIColor clearColor];
19     [self setTitleShadowColor:[UIColor blackColor] forState:UIControlStateNormal];
20     self.titleShadowOffset = CGSizeMake(0, -1);
21     self.titleLabel.font = [UIFont boldSystemFontOfSize:13];
22   }
23
24   return self;
25 }

32 - (void)viewDidLoad {
33     [super viewDidLoad];
34
35     BlueButton *blueButton = [[BlueButton alloc] init];
36     [blueButton setTitle:@"Add" forState:UIControlStateNormal];
37     [blueButton addTarget:self action:@selector(add)
38              forControlEvents:UIControlEventTouchUpInside];
39
40     UIBarButtonItem *button = [[UIBarButtonItem alloc]
41                                                          initWithCustomView:blueButton];
42     self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(Cancel)];
43     self.navigationItem.rightBarButtonItem = button;
44
45     [button release];
46     [blueButton release];
