iOS开发笔记-ios7 UIAlertView自定义

来源：互联网发布：php json数组格式编辑：程序博客网时间：2024/06/05 18:42

之前一个项目适配ios7之后，发现原先的UIAlertView无法正常显示。

后来发现ios7里面原生态的UIAlertView不支持自定义了。

然后就去github上找了下。发现了一个不错的第三方库。和我们之前的使用习惯差不多。

mark一下。

下面给个简单的示例。

1.导入文件。

将这两个文件加入我们的工程下。

2.添加头文件

在需要使用UIAlertView的地方,添加头文件。

#import "CustomIOS7AlertView.h"

并且添加协议。

比如我的.h文件

#import <uikit uikit.h="">#import "CustomIOS7AlertView.h" @interface ViewController : UIViewController<customios7alertviewdelegate> @end</customios7alertviewdelegate></uikit>

3.添加UIAlertView

先给出.m文件。

#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad{    [super viewDidLoad];     // Just a subtle background color    [self.view setBackgroundColor:[UIColor colorWithRed:0.8f green:0.8f blue:0.8f alpha:1.0f]];     // A simple button to launch the demo    UIButton *launchDialog = [UIButton buttonWithType:UIButtonTypeCustom];    [launchDialog setFrame:CGRectMake(10, 30, self.view.bounds.size.width-20, 50)];    [launchDialog addTarget:self action:@selector(launchDialog:) forControlEvents:UIControlEventTouchDown];    [launchDialog setTitle:@"Launch Dialog" forState:UIControlStateNormal];    [launchDialog setBackgroundColor:[UIColor whiteColor]];    [launchDialog setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];    [launchDialog.layer setBorderWidth:0];    [launchDialog.layer setCornerRadius:5];    [self.view addSubview:launchDialog];} - (IBAction)launchDialog:(id)sender{    // Here we need to pass a full frame    CustomIOS7AlertView *alertView = [[CustomIOS7AlertView alloc] init];     // Add some custom content to the alert view    [alertView setContainerView:[self createDemoView]];     // Modify the parameters    [alertView setButtonTitles:[NSMutableArray arrayWithObjects:@"Close1", @"Close2", @"Close3", nil]];    [alertView setDelegate:self];         // You may use a Block, rather than a delegate.    [alertView setOnButtonTouchUpInside:^(CustomIOS7AlertView *alertView, int buttonIndex) {        NSLog(@"Block: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]);        [alertView close];    }];         [alertView setUseMotionEffects:true];     // And launch the dialog    [alertView show];} - (void)customIOS7dialogButtonTouchUpInside: (CustomIOS7AlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex{    NSLog(@"Delegate: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]);    [alertView close];} - (UIView *)createDemoView{    UIView *demoView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 290, 200)];     UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 270, 180)];    [imageView setImage:[UIImage imageNamed:@"demo"]];    [demoView addSubview:imageView];     return demoView;} @end

这里,通过一个button绑定弹出UIAlertView。当然，你也可以在其他条件触发launchDialog方法。

然后UIAlertView载入自己定义的视图(createDemoView)。

另外,块内的setOnButtonTouchUpInside 和单独的delegate customIOS7dialogButtonTouchUpInside方法都能响应我们的选择。

具体选择哪种方式因人而异。
