1:AFNetwork判断网络状态
#import “AFNetworkActivityIndicatorManager.h"- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {//网络[[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
[[AFNetworkReachabilityManager sharedManager] startMonitoring];//网络状态判断[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {switch(status) {caseAFNetworkReachabilityStatusNotReachable:{
[self showMBPHudTipStr:@"当前无网络连接"];
break;
}caseAFNetworkReachabilityStatusReachableViaWiFi:{
[LogUtil logUtilstring:@"WiFi网络"];
break;
}caseAFNetworkReachabilityStatusReachableViaWWAN:{
[self showMBPHudTipStr:@"无线网络"];
break;
}default:
break;
}
}];returnYES;
}
2:UIButton倒计时
当在倒计时uibutton不能被响应事件；-(void)startTime{
__blockinttimeout=60;//倒计时时间dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0);
dispatch_source_t _timer= dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER,0,0,queue);
dispatch_source_set_timer(_timer,dispatch_walltime(NULL,0),1.0*NSEC_PER_SEC,0);//每秒执行dispatch_source_set_event_handler(_timer, ^{if(timeout<=0){//倒计时结束，关闭dispatch_source_cancel(_timer);
dispatch_async(dispatch_get_main_queue(),^{//设置界面的按钮显示 根据自己需求设置[self.againBtn setTitle:@"重发验证码"forState:UIControlStateNormal];
self.againBtn.userInteractionEnabled=YES;
self.labNoMessage.text=@"没有收到验证码吗？";
self.labNoMessage.textColor=[UIColor redColor];
});
}else{intseconds = timeout %60;
NSString*strTime = [NSString stringWithFormat:@"%.2d", seconds];
dispatch_async(dispatch_get_main_queue(),^{//设置界面的按钮显示 根据自己需求设置[self.againBtn setTitle:[NSString stringWithFormat:@"重发激活邮件(%@)",strTime] forState:UIControlStateNormal];
self.againBtn.userInteractionEnabled=NO;
self.labNoMessage.text=@"激活邮件发送成功";
self.labNoMessage.textColor=[UIColor colorWithHexString:@"84BF20"];
});
timeout--;
}
});
dispatch_resume(_timer);
}
3:判断iphone设备
#defineIS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)#defineIS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)#defineIS_RETINA ([[UIScreen mainScreen] scale] >= 2.0)#defineSCREEN_WIDTH ([[UIScreen mainScreen] bounds].size.width)#defineSCREEN_HEIGHT ([[UIScreen mainScreen] bounds].size.height)#defineSCREEN_MAX_LENGTH (MAX(SCREEN_WIDTH, SCREEN_HEIGHT))#defineSCREEN_MIN_LENGTH (MIN(SCREEN_WIDTH, SCREEN_HEIGHT))#defineIS_IPHONE_4_OR_LESS (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)#defineIS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)#defineIS_IPHONE_6 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)#defineIS_IPHONE_6P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
4:在IOS8以下报一个自动布局的BUG,而在IOS8却能正常运行
会导致APP挂掉,BUG内容:
Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Auto Layout still required after executing-layoutSubviews.
UITableView’s implementation of -layoutSubviews needs to call super.’- (void)layoutSubviews
{//自动布局的内容放在super layoutSubviews前面[self _updateConstraints];
[super layoutSubviews];
}
5:与JS交互,并把JS代码兼容android跟IOS
JS代码:
$(function () {varu = navigator.userAgent, app =navigator.appVersion;varisAndroid = u.indexOf('Android') > -1|| u.indexOf('linux') > -1;//android终端或者uc浏览器varisiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/);//ios终端if(isAndroid) {
$('#btn_Success').attr('href','javascript:mailActive.backHome()');
}elseif(isiOS) {
$('#btn_Success').attr('href','protoclo://backHome');
}
});
而IOS则是shouldStartLoadWithRequest:-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSString*newURL=[[request URL] absoluteString];if([newURL hasprefix:@"protoclo://"])
{
NSArray*stringArray=[newURL componentsSeparatedByString:@"//"];if(stringArray.count>1&&[[stringArray objectAtIndex:1] isEqualToString:@"backHome"]) {
[self webJavascriptBackHome];
}
}returnYES;
}
注:比较好IOS的JS交互第三方插件WebViewJavascriptBridge;在IOS开发调试内嵌webView时可以用Safari进行调试,它可以设置出开发模式菜单,开发->ios simulator 就可以实现查看网页的运行详情(Safari->偏好设置-高级-在菜单中显示“开发”);
