I have tried to concatenate to attributed string with different properties,But not reflecting any changes,Here my code
//White color
NSMutableAttributedString *attributedString2 = [[NSMutableAttributedString alloc] initWithData:[[NSString stringWithFormat:#"%#",readingPartCntnt] dataUsingEncoding:NSUnicodeStringEncoding] options:#{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
[attributedString2 addAttribute:NSForegroundColorAttributeName value:[UIColor whiteColor] range:NSMakeRange(0, attributedString2.length)];
[attributedString2 addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, attributedString2.length)];
//Blue color
NSMutableAttributedString *attributedString3 = [[NSMutableAttributedString alloc] initWithData:[[NSString stringWithFormat:#"%#",readingFootCntnt] dataUsingEncoding:NSUnicodeStringEncoding] options:#{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
[attributedString3 addAttribute:NSForegroundColorAttributeName value:[UIColor colorWithRed:(154.0/255.0) green:(224.0/255.0) blue:(250.0/255.0) alpha:1.0] range:NSMakeRange(0, attributedString3.length)];
[attributedString3 addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, attributedString3.length)];
//UITextview
readingContent.attributedText = [NSMutableAttributedString attributedStringWithAttachment:attributedString2,attributedString3];
I want to concatenate both attributedString2 attributedString3 into readingContent.What change required in my code?Please help me to resolve

I am trying to mock different method return when passing different argument for the same method.
self.myMock = [OCMockObject mockForClass:[MyClass class]];
[[[self.myMock expect] andReturnValue:5] myStaticMethod:3];
[[[self.myMock expect] andReturnValue:10] myStaticMethod:6];
But it only takes the first one, when argument is 3 then return 5, and when argument is 6, it return nil instead of 10. Does anyone know whether is a way to test this?
the real code:
-(NSMutableArray*)convertChildStringToChildDic:(NSString*)strchildren
{
NSArray *kididarray = [strchildren componentsSeparatedByString:#","];
//处理小孩信息
/*children = (
{
avatarSmall = "<null>";
currentStatus = 0;
displayName = stu1;
"id_str" = "70938032-3811-e411-946a-005056c00008";
title = Child;
}
)*/
NSMutableArray *rstchildarray = [NSMutableArray arrayWithCapacity:1];
for (NSString *enrollment_id in kididarray) {
if (enrollment_id.length <= 0) {
continue;
}
**NSMutableDictionary *mdic = [[RoomInfoManager sharedManager] getKidDictionaryByID:enrollment_id];**
[mdic setValue:enrollment_id forKey:#"id_str"];
if (mdic != nil) {
[rstchildarray addObject:mdic];
}
}
return rstchildarray;
}
Test:
-(void) testconvertChildStringToChildDic_InvalidAgruments {
NSMutableDictionary *childdic = [[NSMutableDictionary alloc] init];
childdic[#"id"] = #"josh";
NSMutableDictionary *childdic1 = [[NSMutableDictionary alloc] init];
childdic1[#"id"] = #"joy";
id mockRIM = OCMClassMock([RoomInfoManager class]);
**OCMStub([mockRIM getKidDictionaryByID:#"josh"]).andReturn(childdic);
**OCMStub([mockRIM getKidDictionaryByID:#"joy"]).andReturn(childdic1);****
RoomInfoManager *roomInfoMgr = [RoomInfoManager alloc];
id mockPartialRIM = OCMPartialMock(roomInfoMgr);
OCMExpect([mockPartialRIM sharedManager]).andReturn(mockRIM); // use expect
NSString *childStr = #"josh,joy";
NSMutableArray *childarray = [[ReportOperator alloc] convertChildStringToChildDic:childStr];
NSDictionary *childrenArraydic = #{#"id" : #"josh", #"id_str": #"josh"};
NSMutableArray *resultArray = [NSMutableArray arrayWithObjects:childrenArraydic, nil];
[mockPartialRIM verify]; // verify expect,验证该对像是否被调用。
XCTAssertEqualObjects(childarray, resultArray);
}
the second call
OCMStub([mockRIM getKidDictionaryByID:#"joy"]).andReturn(childdic1);
does not seem take effect and return nil instead.
I try to use FirstLineHeadIndent,but when i use, The string will be truncated.
NSString *string = #"hello，i am aaa，123456 my name is";
UIFont *textFont = [UIFont systemFontOfSize:15];
self.textView = [UILabel new];
_textView.backgroundColor = [UIColor clearColor];
[self.view addSubview:_textView];
_textView.numberOfLines = 0;
NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
paragraphStyle.lineHeightMultiple = 1.4;
[paragraphStyle setLineSpacing:4];
[paragraphStyle setFirstLineHeadIndent:30];
[paragraphStyle setAlignment:NSTextAlignmentJustified];
[paragraphStyle setLineBreakMode:NSLineBreakByWordWrapping];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:string attributes:#{NSParagraphStyleAttributeName:paragraphStyle,NSFontAttributeName:textFont,NSForegroundColorAttributeName:[UIColor darkGrayColor]}];
[_textView setAttributedText:string];
The results of the intercept is hello，i am aaa，123456 my.
about the first line retract, am i wrong? thanks！
Using NSCalendar and its method dateByAddingComponents:toDate:options: the method sometimes return a wrong value. For instante:
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setYear:2013];
[components setMonth:2];
[components setDay:27];
NSDate *date = [calendar dateFromComponents:components];
NSLog(#"%#", date); // 2013-02-27
NSDateComponents *addingComponents = [[NSDateComponents alloc] init];
[addingComponents setMonth:1];
[addingComponents setDay:4]; // value 5 give the same result.
date = [calendar dateByAddingComponents:addingComponents toDate:date options:0];
NSLog(#"%#", date); // 2013-03-31
The console log: 2013-02-27 and 2013-03-31.
Now, if a change the day component value to 5, the method return the same NSDate, but if a change to 6, the date if 2013-04-01.
Anyone has an answer for this behavior? Thanks on advance.

I am currently using a UILabel to display multiple lines of text. The line break most is set to NSLineBreakByWordWrapping so the the label automatically inserts line breaks. How can I detect where those line breaks are? Basically, I want to return a string with each \n break included.
Here is my work around for detecting line breaks inside UILabel
- (int)getLengthForString:(NSString *)str fromFrame:(CGRect)frame withFont:(UIFont *)font
{
int length = 1;
int lastSpace = 1;
NSString *cutText = [str substringToIndex:length];
CGSize textSize = [cutText sizeWithFont:font constrainedToSize:CGSizeMake(frame.size.width, frame.size.height + 500)];
while (textSize.height <= frame.size.height)
{
NSRange range = NSMakeRange (length, 1);
if ([[str substringWithRange:range] isEqualToString:#" "])
{
lastSpace = length;
}
length++;
cutText = [str substringToIndex:length];
textSize = [cutText sizeWithFont:font constrainedToSize:CGSizeMake(frame.size.width, frame.size.height + 500)];
}
return lastSpace;
}
-(NSString*) getLinebreaksWithString:(NSString*)labelText forWidth:(CGFloat)lblWidth forPoint:(CGPoint)point
{
//Create Label
UILabel *label = [[UILabel alloc] init];
label.text = labelText;
label.numberOfLines = 0;
label.lineBreakMode = NSLineBreakByWordWrapping;
//Set frame according to string
CGSize size = [label.text sizeWithFont:label.font
constrainedToSize:CGSizeMake(lblWidth, MAXFLOAT)
lineBreakMode:UILineBreakModeWordWrap];
[label setFrame:CGRectMake(point.x , point.y , size.width , size.height)];
//Add Label in current view
[self.view addSubview:label];
//Count the total number of lines for the Label which has NSLineBreakByWordWrapping line break mode
int numLines = (int)(label.frame.size.height/label.font.leading);
//Getting and dumping lines from text set on the Label
NSMutableArray *allLines = [[NSMutableArray alloc] init];
BOOL shouldLoop = YES;
while (shouldLoop)
{
//Getting length of the string from rect with font
int length = [self getLengthForString:labelText fromFrame:CGRectMake(point.x, point.y, size.width, size.height/numLines) withFont:label.font] + 1;
[allLines addObject:[labelText substringToIndex:length]];
labelText = [labelText substringFromIndex:length];
if(labelText.length<length)
shouldLoop = NO;
}
[allLines addObject:labelText];
//NSLog(#"\n\n%#\n",allLines);
return [allLines componentsJoinedByString:#"\n"];
}
How to use
NSString *labelText = #"We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far.";
NSString *stringWithLineBreakChar = [self getLinebreaksWithString:labelText forWidth:200 forPoint:CGPointMake(15, 15)];
NSLog(#"\n\n%#",stringWithLineBreakChar);
You just need to set parameters required by getLinebreaksWithString and you will get a string with each "\n" break included.

Here is my solution to this problem.
I iterate through all whitespace characters in the provided string, set substrings (from beginning to current whitespace) to my label and check the difference in the height. When the height changes I insert a new line character (simulates a line break).
func wordWrapFormattedStringFor(string: String) -> String {
// Save label state
let labelHidden = label.isHidden
let labelText = label.text
// Set text to current label and size it to fit the content
label.isHidden = true
label.text = string
label.sizeToFit()
label.layoutIfNeeded()
// Prepare array with indexes of all whitespace characters
let whitespaceIndexes: [String.Index] = {
let whitespacesSet = CharacterSet.whitespacesAndNewlines
var indexes: [String.Index] = []
string.unicodeScalars.enumerated().forEach { i, unicodeScalar in
if whitespacesSet.contains(unicodeScalar) {
let index = string.index(string.startIndex, offsetBy: i)
indexes.append(index)
}
}
// We want also the index after the last character so that when we make substrings later we include also the last word
// This index can only be used for substring to this index (not from or including, since it points to \0)
let index = string.index(string.startIndex, offsetBy: string.characters.count)
indexes.append(index)
return indexes
}()
var reformattedString = ""
let boundingSize = CGSize(width: label.bounds.width, height: CGFloat.greatestFiniteMagnitude)
let attributes = [NSFontAttributeName: font]
var runningHeight: CGFloat?
var previousIndex: String.Index?
whitespaceIndexes.forEach { index in
let string = string.substring(to: index)
let stringHeight = string.boundingRect(with: boundingSize, options: .usesLineFragmentOrigin, attributes: attributes, context: nil).height
var newString: String = {
if let previousIndex = previousIndex {
return string.substring(from: previousIndex)
} else {
return string
}
}()
if runningHeight == nil {
runningHeight = stringHeight
}
if runningHeight! < stringHeight {
// Check that we can create a new index with offset of 1 and that newString does not contain only a whitespace (for example if there are multiple consecutive whitespaces)
if newString.characters.count > 1 {
let splitIndex = newString.index(newString.startIndex, offsetBy: 1)
// Insert a new line between the whitespace and rest of the string
newString.insert("\n", at: splitIndex)
}
}
reformattedString += newString
runningHeight = stringHeight
previousIndex = index
}
// Restore label
label.text = labelText
label.isHidden = labelHidden
return reformattedString
}

This solution worked really well in my case, hope it helps.
This is the Resolution for Paypal (Sandbox) Error "589023" in iPhone Application
-(void)payWithPayPal{
for (int i=0;i
PayPal *payPal=[PayPal getPayPalInst];
payPal.shippingEnabled = FALSE;
payPal.dynamicAmountUpdateEnabled = NO;
payPal.feePayer = FEEPAYER_EACHRECEIVER;
PayPalPayment *payment = [[[PayPalPayment alloc] init] autorelease];
payment.recipient = #"UKMCA2010#GMAIL.COM";
payment.paymentCurrency = #"USD";
payment.description = #"Payment Discription here...";
SampleSingleton *sample=[SampleSingleton sharedInstance];
payment.merchantName =[sample getStrRestaurantName];

payment.invoiceData.invoiceItems = [NSMutableArray array];
PayPalInvoiceItem *item = [[PayPalInvoiceItem alloc] init];
item.totalPrice=[NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:#"%.2f", 126.34545]]; // If u give xxx.xx , no need to give the %.2f , u can give directly %f
item.name = objTempReceived.strItemName;
item.itemId = #"Item ID";
[payment.invoiceData.invoiceItems addObject:item];
[item release];
}
payment.subTotal = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:#"%.2f",126.34545]]; //Total and Subtotal must be equal
payment.invoiceData.totalTax = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:#"%.2f",3.34]];
NSLog(#"Total Tax is :%#",[payment.invoiceData.totalTax stringValue]);
[payPal checkoutWithPayment:payment];
}
Here the total and subtotal and Tax allows only two digits after the .(dot) Ex: (234.xx). So by using the %.2f to work perfectly.
