ios7 UIAlertView自定义

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。

<CustomIOS7AlertViewDelegate>

比如我的.h文件

#import <UIKit/UIKit.h>
#import "CustomIOS7AlertView.h"

@interface ViewController : UIViewController<CustomIOS7AlertViewDelegate>

@end

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。
