自己整理的ios app实现自动升级

主要是写cordova插件

<!---------------------------CheckUpdate.h文件----------------------------------------->

#import <Cordova/CDVPlugin.h>

@interface CheckUpdate : CDVPlugin{

NSString *trackViewUrl;

}

@property (nonatomic,retain) NSString *trackViewUrl;

- (void)checkUpdate:(NSMutableArray*)arguments withDict:(NSDictionary*)options;

@end

<!---------------------------CheckUpdate.m文件----------------------------------------->

#import "CheckUpdate.h"

@implementation CheckUpdate

@synthesize trackViewUrl;

- (void)checkUpdate:(NSMutableArray*)arguments withDict:(NSDictionary*)options{

NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];

NSString *nowVersion = [infoDict objectForKey:@"CFBundleVersion"];

NSError *error;

NSURL *url = [NSURL URLWithString:@"http://itunes.apple.com/lookup?id=739680648"];

NSURLRequest *request= [NSURLRequest requestWithURL:url];

NSData *response=[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

NSDictionary *dict= [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];

NSArray *res= [dict objectForKey:@"results"];

if([res count]){

NSDictionary *resDict= [res objectAtIndex:0];

NSString *newVersion = [resDict objectForKey:@"version"];

self.trackViewUrl=[resDict objectForKey:@"trackViewUrl"];

if([nowVersion isEqualToString:newVersion]==NO)

{

NSString *message=[[NSString alloc] initWithFormat:@"当前版本为%@，最新版本为%@", nowVersion, newVersion];

UIAlertView *alert= [[UIAlertView alloc] initWithTitle:@"检测版本更新" message:message delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"更新", nil ];

[alert show];

[alert release];

}else{

UIAlertView *alert= [[UIAlertView alloc] initWithTitle:@"检测版本更新" message:@"已经是最新版本了" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:nil];

[alert show];

[alert release];

}

}

}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

if(buttonIndex == 1){

NSURL *url= [NSURL URLWithString: self.trackViewUrl];

[[UIApplication sharedApplication] openURL:url];

[url release];

}

}

@end
