Iphone SKPSMTPMessage和UIProgressView

我正在使用这个图书馆http://code.google.com/p/skpsmtpmessage/ 在我的iPhone应用程序中发送电子邮件

如何在发送过程中实现UIProgressView

谢谢你的帮助

1.在.h中创建UIProgressView以及BOOL和NSTimer，并 一个名为updateProgress的函数

2.在.m文件中进行合成

3.在viewDidLoad中，将BOOL的初始值设置为NO，并创建一个 计时器

您的.h文件应该包括

UIProgressView * progressView;
BOOL emailSent;
NSTimer * timer;

-(void)updateProgress;
@property(nonatomic, retain)UIProgressView * progressView;
@property(nonatomic, assign)BOOL emailSent;
@property(nonatomic, retain)NSTimer * timer;

@synthesize progressView, emailSent,timer;

//viewdidload
//set initial value to no
emailSent = NO;

//since we cant interact with UIElements on anything but the Main thread we use a timer
//because you are probably sending the email in a seperate thread
timer= [NSTimer scheduledTimerWithTimeInterval:.1 target:self selector:@selector(updateProgress) userInfo:nil repeats:YES];

//create this function
-(void)updateProgress{


    //wait for email to be done
    if (emailSent == NO) {

// you'll have to tweak this area to get the correct data "progress"    
float fullValue = .0032;
int progressInt = (app.parsedCount * z);

//progressInt is the representation of how much data has been completed.
        progressView.progress = progressInt;
    }
    else {

    //email is done 
    emailSent = YES;

        //kill the timer so it doesnt continue to run
    [timer invalidate];
    //email sent so you can remove your progress view
         [self.view removeSubView:progressView];
    }
}

你的.m文件应该包括

UIProgressView * progressView;
BOOL emailSent;
NSTimer * timer;

-(void)updateProgress;
@property(nonatomic, retain)UIProgressView * progressView;
@property(nonatomic, assign)BOOL emailSent;
@property(nonatomic, retain)NSTimer * timer;

@synthesize progressView, emailSent,timer;

//viewdidload
//set initial value to no
emailSent = NO;

//since we cant interact with UIElements on anything but the Main thread we use a timer
//because you are probably sending the email in a seperate thread
timer= [NSTimer scheduledTimerWithTimeInterval:.1 target:self selector:@selector(updateProgress) userInfo:nil repeats:YES];

//create this function
-(void)updateProgress{


    //wait for email to be done
    if (emailSent == NO) {

// you'll have to tweak this area to get the correct data "progress"    
float fullValue = .0032;
int progressInt = (app.parsedCount * z);

//progressInt is the representation of how much data has been completed.
        progressView.progress = progressInt;
    }
    else {

    //email is done 
    emailSent = YES;

        //kill the timer so it doesnt continue to run
    [timer invalidate];
    //email sent so you can remove your progress view
         [self.view removeSubView:progressView];
    }
}

好的。。但我的问题是，你说你必须调整这个区域以获得正确的数据进度，非常感谢你@路易：詹基提到的对我来说也很有趣！我的意思是，我知道，大概是邮件的大小，但不知道在通过课堂发送电子邮件时当前发送了多少！我真的不想编辑SKPSMTPMessage类来获取当前进度状态的信息，但我想，这是唯一的选择，对吗？顺便说一句，有了计时器，这实际上是一个很好的观点！
