iOS开发-自定义UIAlterView(iOS 7)

App中不可能少了弹框，弹框是交互的必要形式，使用起来也非常简单，不过最近需要自定义一个弹框，虽然iOS本身的弹框已经能满足大部分的需求，但是不可避免还是需要做一些自定义的工作。iOS7之前是可以自定义AlterView的，就是继承一下UIAlterView，然后初始化的时候通过addSubview添加自定义的View，但是iOS7之后这样做就不行了，不过还好有开源项目可以解决这个问题。

iOS默认弹框

viewDidLoad中添加两个按钮，代码如下:

UIButton  *orignalBtn=[[UIButton alloc]initWithFrame:CGRectMake(100, 40, 100, 50)];
[orignalBtn setBackgroundColor:[UIColor greenColor]];

[orignalBtn setTitle:@"iOS弹框" forState:UIControlStateNormal];

[orignalBtn addTarget:self action:@selector(orignalShow) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:orignalBtn];
 
UIButton  *customlBtn=[[UIButton alloc]initWithFrame:CGRectMake(100, 140, 100, 50)];
[customlBtn setBackgroundColor:[UIColor redColor]];

[customlBtn setTitle:@"自定义弹框" forState:UIControlStateNormal];

[customlBtn addTarget:self action:@selector(customShow) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:customlBtn];

　响应默认弹框事件:

-(void)orignalShow{

    UIAlertView *alterView=[[UIAlertView alloc]initWithTitle:@"提示" message:@"博客园-Fly_Elephant" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

    [alterView show];
}

　　效果如下:

自定义弹框

主要解决iOS7之后的系统无法自定义弹框的问题，使用开源项目，项目地址:https://github.com/wimagguc/ios-custom-alertview,其实就是自定义了一个类:

CustomIOSAlertView.h

#import <UIKit/UIKit.h>
 
@protocol CustomIOSAlertViewDelegate
 
- (void)customIOS7dialogButtonTouchUpInside:(id)alertView clickedButtonAtIndex:(NSInteger)buttonIndex;
 
@end
 
@interface CustomIOSAlertView : UIView<CustomIOSAlertViewDelegate>
 
@property (nonatomic, retain) UIView *parentView;    // The parent view this 'dialog' is attached to

@property (nonatomic, retain) UIView *dialogView;    // Dialog's container view

@property (nonatomic, retain) UIView *containerView; // Container within the dialog (place your ui elements here)
 
@property (nonatomic, assign) id<CustomIOSAlertViewDelegate> delegate;

@property (nonatomic, retain) NSArray *buttonTitles;

@property (nonatomic, assign) BOOL useMotionEffects;
 
@property (copy) void (^onButtonTouchUpInside)(CustomIOSAlertView *alertView, int buttonIndex) ;
 
- (id)init;
 
/*!

 DEPRECATED: Use the [CustomIOSAlertView init] method without passing a parent view.

 */

- (id)initWithParentView: (UIView *)_parentView __attribute__ ((deprecated));
 
- (void)show;

- (void)close;
 
- (IBAction)customIOS7dialogButtonTouchUpInside:(id)sender;

- (void)setOnButtonTouchUpInside:(void (^)(CustomIOSAlertView *alertView, int buttonIndex))onButtonTouchUpInside;
 
- (void)deviceOrientationDidChange: (NSNotification *)notification;

- (void)dealloc;
 
@end

CustomIOSAlertView.m

调用代码:

-(void)customShow{

    CustomIOSAlertView *alertView = [[CustomIOSAlertView alloc] init];

    [alertView setContainerView:[self customView]];

    [alertView setButtonTitles:[NSMutableArray arrayWithObjects:@"取消", @"确定", nil]];

    [alertView setDelegate:self];

    [alertView setOnButtonTouchUpInside:^(CustomIOSAlertView *alertView, int buttonIndex) {

        NSString *result=alertView.buttonTitles[buttonIndex];

        NSLog(@"点击了%@按钮",result);

        [alertView close];

    }];

    [alertView setUseMotionEffects:true];

    [alertView show];
 
}
 
- (UIView *)customView
{

    UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 240, 160)];

    UILabel *tip=[[UILabel alloc]initWithFrame:CGRectMake(100, 10, 50, 30)];

    [tip setText:@"提示"];

    [customView addSubview:tip];

    UILabel *content=[[UILabel alloc]initWithFrame:CGRectMake(10, 60, 210, 30)];

    [content setText:@"http://www.cnblogs.com/xiaofeixiang"];

    [content setFont:[UIFont systemFontOfSize:12]];

    [customView addSubview:content];

    return customView;
}

　效果如下:
