Strange UILabel

[gagvx290]

Hi,

I have got a bit of an issue with trying to get a line break to appear in a UILabel view. I have looked around on this forum and several other and found fixes for specific cases but none that seems to work for me.

I am using:

NSString *response = [NSString stringWithContentsOfURL:requestURL encoding:NSASCIIStringEncoding error:&error];

To hit my server which calls a php script that returns a string to my app. My app then uses:

NSArray *myArray = [[tableData objectAtIndex:row] componentsSeparatedByString:@"/484"];

to split the string that we returned into an array of smaller strings. I then set the text of a label to one of these smaller strings as follows:

[myLabel setText:[myArray objectsatIndex:0]];

The string stored in the array is definitely valid, and contains a "\n", and a "\r" just in case, but when I load the app it just displays the "\n" and "\r" as text and does not move to the next line.

If anyone has any idea why this is happening, or how I might be able to fix it, it would be much appreciated.

Thanks

This is from the Xcode documentation on UILabel:

numberOfLines
The maximum number of lines to use for rendering text.

@property(nonatomic) NSInteger numberOfLines
Discussion
This property controls the maximum number of lines to use in order to fit the label’s text into its bounding rectangle. The default value for this property is 1. To remove any maximum limit, and use as many lines as needed, set the value of this property to 0.

If you constrain your text using this property, any text that does not fit within the maximum number of lines and inside the bounding rectangle of the label is truncated using the appropriate line break mode.

When the receiver is resized using the sizeToFit method, resizing takes into account the value stored in this property. For example, if this property is set to 3, the sizeToFit method resizes the receiver so that it is big enough to display three lines of text.

The documentation is a wonderful thing.

Thanks, but I have numberOfLines set to 0, and my label quite happily wraps onto multiple lines so that it fits into the view. The problem is with wanting to add line breaks using the "\n" character at a user defined point within the text that is in the label. Setting this property does not seem to help with this..?
